Description

The technical field

The invention relates to the field of aldimines and moisture curing polyurethane polymers.

The level of technology

Polyurethane compositions are precursors to synthetic materials, which for a long time are used, for example, as adhesives, sealants, coatings and linings. Usually they include containing isocyanatomethyl polymer derived from polyols and polyisocyanates, which are mixed with other components and to the application stored in the absence of moisture. This song is called one-component composition, it cures when exposed to moisture on a synthetic material. These in themselves known systems have the disadvantage that when they are curing, followed by the release of carbon dioxide (CO2) the reaction of isocyanate groups with water, the cured synthetic material can begin the formation of undesirable gas bubbles; this happens in particular when the curing rate is high. To suppress the formation of bubbles during curing isocyanatomethyl compositions in the composition can be added blocked amines, for example in the form of aldimines as a so-called "latent amines" or "latent hardeners". Upon contact with moisture blocked amino latent the of tergites hydrolyzed and then react with the isocyanate groups of the composition without allocation of CO 2. The use of aldimines as latent hardeners in isocyanatomethyl composica described, for example, in patent US 3420800. However, the presence aldimine fraught with the danger that the composition due to the outbreak of premature reaction between alliminum and isocyanate groups will be stable when stored for only a short time or it might not be stable.

Known for containing aldimine composition based on isocyanates, distinguished by good storage stability, as, for example, described in documents US 4469831, US 4853454 and US 5087661. In document WO 2004/013200 A1 describes containing polyamideimide compositions, which are stable in storage and which, if moisture otverzhdajutsja odorless. The composition described in the above publications have the disadvantage that they are for curing relatively a lot of water, which is twice more than in the case when present in the composition isocyanatomethyl polyurethane polymer cures without latent hardener, i.e. in the direct reaction of isocyanate groups with water. In the case of curing with moisture of the air composition hardens from outside to inside, and the water required for the curing reaction must diffuse through becoming thicker layer of synthetic material; therefore, the availability of water, especially when the use of the drop of thick layers of the composition, becomes the limiting factor already after a short time of reaction curing. Therefore, increased consumption of water leading to the curing of the crosslinking reactions automatically leads to slower curing.

Isocyanatobenzene compositions which require curing less water than the system described above, is known. So, in patents US 4108842, US 4404379 and US 6136942 describes compositions which contain reaction products of polyisocyanates and amidofunctional of aldimines, or cyclonically as their tautomeric forms, and which quickly otverzhdajutsja adding moisture and can be applied, for example, as adhesives, sealants or coatings. However, the composition described in the above-mentioned publications, have poor stability during storage. This is due to the fact that they contained a protected amino group, in the form of alvinovich or cyclonically groups do not remain completely inert towards isocyanate groups, and slow to respond to them, particularly with reactive aromatic isocyanate groups, in the absence of moisture, and thereby cause an increase in viscosity, which already after a short time can make the composition unusable. In addition, when applying the compositions have an unpleasant smell due to the emitted during curing (as a result of hydrolysis alvinegro) aldehydes, and so are limitedly applicable, especially in the interior of the applicable limited. In addition, compositions according to the US 6136942 in utverzhdenii form have problems with lightfastness.

Detailed description of the invention

In this regard, the present invention is to develop compositions that are stable during storage, quickly and without bubbles otverzhdajutsja with the introduction of moisture during curing does not cause the formation of odor and are suitable as precursors of synthetic materials. It was unexpectedly found that this problem is solved eliminatorias connection on p. 1 of the claims.

These compositions have excellent storage stability. Adding moisture they quickly otverzhdajutsja without the formation of bubbles and odorless. They are suitable as precursors of synthetic materials, in particular for use as adhesives, sealants, coatings and linings, which can also be used in applications involving no odor, such as bonding, sealing, coating or flooring inside vehicles or buildings, and which have very good properties, in particular, high early strength. Other forms of implementation are subject to the following independent claims. Other advantageous form of implementation, the image is etenia emerge from the dependent claims.

Ways of carrying out the invention

The object of the invention are compositions that include at least one containing isocyanatomethyl the polymerPand at least one eliminatorias compound of formula (I). This isocyanatomethyl polyurethane polymerPobtained from at least one MDI and at least one polyol.

In the formula (I), m denotes an integer from 1 to 4, p is an integer from 1 to 6, and q denotes an integer from 0 to 5, with the proviso that the sum of p and q is from 2 to 6. Further, R1means any monovalent hydrocarbon residue with 6-30 C atoms, which may contain at least one heteroatom, in particular in the form of a simple oxygen of the ether, or R1means the Deputy of the formula (II).

Thus R6means a divalent hydrocarbon residue with 2 to 20 C atoms, which may contain at least one heteroatom, in particular in the form of a simple oxygen ether. R7means monovalent hydrocarbon residue with 1-20 atoms C.

Further, R2and R3mean either two independent from each other Deputy, who represent a monovalent hydrocarbon residue with 1 to 12 C atoms, or R2and R3the place constitute the only Deputy, represents a divalent hydrocarbon residue with 4 to 20 C atoms, which is part of a carbocyclic ring with 5 to 8, preferably 6 atoms C. This carbocyclic ring may in any case be substituted.

Further, R4means (m+1)-valent hydrocarbon residue with 2 to 12 C atoms, which may contain at least one heteroatom, in particular in the form of a simple oxygen ether or tertiary amine nitrogen.

Further, R5means either (p+q)-valent organic residue (the residue may contain heteroatoms and may be obtained by removing (p+q) NCO-groups of R5-[NCO]p+qor R5means N, NR14, O, OC(O)O, Si, P(O)O3or SO2. Thus R14means monovalent hydrocarbon residue with 1-20 atoms C.

In addition, X represents O, S or N-R8and here R8means any monovalent hydrocarbon residue with 1-20 C atoms, which may contain at least one group of ester of carboxylic acid, a nitrile, a nitro-group, a group of ester phosphonic acid, sulfonic group or the group of ester sulfonic acid or means the Deputy of the formula (III).

The dotted line in formulas indicate connection with the above substituents.

Containing aldimine connected to the e of the formula (I) can be obtained by reaction of at least one aldimine formula (XI), containing active hydrogen, with at least one polyisocyanateD. When this bearing active hydrogen reactive group aldimine formula (XI) is reacted in the reaction of joining with one or more isocyanate groups MDIDwith the formation of eliminatorias the compounds of formula (I), hereinafter also called the "product of accession". The term "active hydrogen" in this document means capable of deprotonation of the hydrogen atom linked to the nitrogen atom, oxygen or sulfur. The term "reactive group containing active hydrogen"means a functional group bearing an active hydrogen, in particular primary or secondary amino group, hydroxyl group, mercaptopropyl or group of urea. These distinctive properties of substances, as eliminatethe" or "isocyanatomethyl"indicates that these substances are specified functional groups, i.e. aldimine group or isocyanate group. The prefix "poly" in the designation of substances, for example, "polyamidimide", "polyamine, polyisocyanate or polyol" in this document indicates that the corresponding substance is formally molecule contains more than one functional group which brought his name.

R1, R2 , R3, R4and X and m have the meanings already described for containing aldimine the compounds of formula (I).

Aldimine formula (XI) can be obtained from at least one sterically constrained aliphatic aldehydeAand at least one aliphatic amineBcorresponding to the formula [H2N]m-R4-XH, which, along with one or more primary amino groups includes another reactive group containing active hydrogen.

The interaction between the aldehydeAand AminBoccurs in the condensation reaction with elimination of water. Such condensation reaction is well known and is described, for example, in Houben-Weyl, "Methods der organischen Chemie", Vol. XI/2, page 73ff. This aldehydeAused in stoichiometric amount or in a stoichiometric excess in relation to the primary amino groups AminB. Usually such the condensation reaction is conducted in the presence of a solvent, whereby formed during the reaction, water is diverted azeotrope. However, for aldimines formula (XI) is the preferred way to obtain without the use of solvents, and formed by condensation water is drained from the reaction mixture directly by application of vacuum. Upon receipt in the absence of solvent becomes unnecessary Stripping of the solvent on okoncane the receipt, that simplifies the process of obtaining. In addition, this aldimine has no residual solvent, which could be the cause of odor.

To obtain aldimine formula (XI) used at least one sterically hindered aliphatic aldehyde A formula (IV).

In the formula (IV) R1, R2and R3have the same value as what is described for formula (I).

AldehydeAhas no smell. Under the substance "unscented" means a substance that has such a weak smell, that it is for most people imperceptible, that is not perceived by the nose.

AldehydeAget, for example, from carboxylic acids R1-COOH and β-hydroxyaldehyde formula (V) in the esterification reaction. This esterification can be carried out by known methods described, for example, in Houben-Weyl "Methods der organischen Chemie", Vol. VIII, p. 516-528. β-Hydroxyaldehyde formula (V) are obtained, for example, in the cross-aldol condensation of formaldehyde (or oligomeric forms of formaldehyde as paraformaldehyde or 1,3,5-trioxane) and the aldehyde of formula (VI).

In formulas (V) and (VI) R2and R3shall have the same meaning as described for formula (I).

Obtaining aldehydeAis carried out preferably without solvent. While β-hydroxyaldehyde formula (V) and without the use of solvents is directly in the reaction with carboxylic acid, and formed by the esterification of the water is removed in vacuum. In addition, it is preferable to carry out the aldol condensation and esterification leading to the aldehydeA,from the source materials in a common process step, for example, in one reactor.

The interaction of the aldehydeAwith AminCwith the formation of an intermediate product of the formula (VII) occurs in the condensation reaction with elimination of water, as already described above for the interaction of the aldehydeAwith AminB. Thus the stoichiometry between the aldehydeAand AminCis chosen so that m moles of aldehydeAhad 1 mol amineC, which contains m+1 mol of primary amino groups. The preferred method of obtaining without solvent, and formed by condensation water is removed from the reaction mixture by application of vacuum.

Reaction of the intermediate product of the formula (VII) with a Michael acceptor of the formula (VIII) is conducted, for example, the fact that the intermediate product in a stoichiometric or slightly oversexualization number mixed with a Michael acceptor of the formula (VIII) and the mixture is heated to a temperature of from 20 to 110°C until complete conversion of the intermediate products which act in algemin formula (XI). The reaction is preferably carried out without solvents.

In certain cases aldimine formula (XI) can be in equilibrium with cyclic forms, which for example is shown by formula (X). These cyclic form in the case of aminoalkenes are cyclic aminase, as, for example, imidazolidin or tetrahydropyrimidin; in the case of hydroxyarginine - cyclic aminoacetate, as, for example, oxazolidin or tetrahydrooxazolo; in the case of mercaptoethylamine - cyclic thiaminase, as, for example, thiazolidin or tetrahydrothiophene.

In the formula (X) m, R1, R2, R3, R4and X have the same values as described for formula (I).

It was unexpectedly found that the majority of aldimines formula (XI) are not prone to cyclization. In particular, for aminoalkenes using the methods of IR - and NMR-spectroscopy it is possible to show that these compounds are mainly in the form of open circuits, i.e. in aliminosa form, while cyclical, meaning that analnye forms, are absent or are present only in trace quantities. This differs from the behavior of aminoalkenes corresponding to the prior art, which are described, for example, in US 4404379 and US 6136942: those are always predominantly in the form of cycloamylose. Also, hydroxy - and mercaptoamines, in which the s primary amino group separated from hydroxy, accordingly mercaptopropyl chain of at least 5 atoms, or ring, does not detect cyclization. The almost total absence of cyclic structures in aldimine formula (XI) should be regarded as an advantage, in particular from the point of view of their application in isocyanatomethyl compositions, so as thereby aldimine are inherently contained in aminullah, oxazolidine and thioamines basic nitrogen atoms, which may degrade the stability isocyanatomethyl composition during storage.

Aldimine formula (XI) are odorless. In suitable conditions, in particular with the exclusion of moisture, they are stable during storage. When moisture aldimine group of aldimines can be either hydrolyzed through an intermediate stage, formally, to the amino groups, and allocates the corresponding aldehydeAused to obtain aldimine. Since this hydrolysis reaction is reversible and the chemical equilibrium is markedly shifted towards aldimine, should proceed from the fact that in the absence of active amines groups partially or completely hydrolyzed only part alvinovich groups.

As MDIDsuitable two - or polynuclear Monomeric and/or oligomeric aliphatic, cycloaliphatic, arylaliphatic and aromatic polyisocyanates of the formula (XII),

as, for example, 1,6-hexamethylenediisocyanate (HDI), 2-methylpentanediol-1,5-diisocyanate, 2,2,4 - and 2,4,4-trimethyl-1,6-hexamethylenediisocyanate (TMDI), 1,12-dodecyltrimethoxysilane, lysine diisocyanate and lysine ester, cyclohexane-1,3 - and -1,4-diisocyanate and any mixtures of these isomers, 1-isocyanato-3,3,5-trimethyl-5-isocyanatomethyl (=isophorondiisocyanate, or IPDI), perhydro-2,4'- and -4,4'-diphenylmethanediisocyanate (HMDI), 1,4-diisocyanato-2,2,6-trimethylcyclohexane (TMCDI), 1,3 - and 1,4-bis-(isocyanatomethyl)-cyclohexane, m - and p-xylylenediisocyanate (m - and p-XDI), 1,3,5-Tris-(isocyanatomethyl)-benzene, m - and p-tetramethyl-1,3 - and -1,4-xylylenediisocyanate (m - and p-TMXDI), bis-(1-isocyanato-1-methylethyl)-naphthalene, α,α,α',α',α",α"-HEXAMETHYL-1,3,5-mesitylenesulfonic, dimeric and trimeric isocyanates fatty acids, as 3,6-bis-(9-isocyanatophenyl)-4,5-di-(1-heptenyl)-cyclohexan (dimerisation), 2,4 - and 2,6-toluylenediisocyanate and any mixtures of these isomers (TDI), 4,4'-, 2,4'- and 2,2'-diphenylmethanediisocyanate and any mixtures of these isomers (MDI), mixtures of MDI and MDI homologs (polymer MDI or PMDI), 1,3 - and 1,4-delete the entry, 2,3,5,6-tetramethyl-1,4-diisocyanates, naphthalene-1,5-diisocyanate (NDI), 3,3'-dimethyl-4,4'-diisocyanatobutane (TODI), Tris-(4-isocyanatophenyl)-methane, Tris-(4-isocyanatophenyl)-thiophosphate; oligomers of these isocyanates containing uretdione, which is or iminoimidazolidine group; modi is these two - and polynuclear isocyanates, containing ester -, urethane-, biuret-, allophanate, carbodiimide, uretonimine, oxadiazoline group or urea group; and isocyanatobenzene polyurethane polymers, i.e. containing more than one isocyanate group of the reaction products of polyisocyanates with substances containing two or more hydroxyl groups (the so-called "polyols"), as, for example, two - or polynuclear alcohols, glycols or aminoalcohols, polyhydroxybutyrate ethers, polyesters, polyacrylates, polycarbonates or paleogeography, in particular, polyethers.

The interaction between aldimines formula (XI) and polyisocyanateDwith the formation of the product of accession, meet the formula (I), is carried out in known conditions, which are typically used for the reaction between the reactive groups involved in the relevant transformations, for example, at a temperature of from 20 to 100°C. the Reaction is carried out using a solvent or preferably without solvents. It is possible, may optionally be used excipients, such as, for example, catalysts, initiators or stabilizers. For aminoacidemia reaction is carried out preferably at room temperature without catalyst, hydroxy-, mercapto - and mcevisualaid - when temperature is from 40 to 100°C and using a catalyst, what is used for the reaction between isocyanates and alcohols to form urethanes, for example ORGANOTIN compound, a complex of bismuth, a tertiary amine compound or a combination of such catalysts.

If the response of the merger between aldimines formula (XI) and polyisocyanateDto obtain eliminatorias the compounds of formula (I) is carried out with stoichiometric proportions, i.e., one molar equivalent of active hydrogen aldimine one molar equivalent of isocyanate groups MDIDeliminating the reactive group reacts completely, as a product of accession, meet the formula (I), is obtained polyamidimide. A simple way to get a variety of polyamidimide without needing to obtain the corresponding primary polyamines, which are only partially accessible in industry and Commerce. Depending on the structure, functionality and molecular weight MDIDand aldimines formula (XI) these polyamidimide may have very different properties; thus, they can be chosen according to the needs for specific applications.

If, on the contrary, the reaction of the merger between aldimines formula (XI) and polyisocyanateDheld in posteriorities conditions, i.e. when is the Eney than one molar equivalent of active hydrogen aldimine one molar equivalent of isocyanate groups MDI (which isocyanate groups will react only partially), the quality of the product attach it turns out heterofunctional compound, i.e. the compound of formula (I), which in addition to one or more alvinovich groups has one or more isocyanate groups. It is shown that the value of the index q is greater than 0.

Collected in this way the addition products of aldimines formula (XI) to the MDIDi.e. aldimine-containing compounds of the formula (I), does not smell, as aldimine formula (XI). In suitable conditions, in particular in the absence of moisture, they are stable when stored.

Aldimine formula (XI), and eliminatorias the compounds of formula (I) have a very wide scope. In principle, they can be used everywhere, where they can serve as a source of aldehydes of the formula (IV) and/or aminesB. In particular they can be used in functions protected amines, respectively, protected aldehydes, active aldehyde and/or amine systems, and there may purposefully protection may be removed. In particular, they find application in systems in which there are compounds that react with primary amines. Removing the protection is carried out hydrolytically, for example, by contact with water or moisture, in particular air moisture.

When moisture aldimine product group accession of the formula (I) can hydrolysates through an intermediate stage, formally to the amino groups, and allocates the corresponding aldehydeAused to obtain aldimine formula (XI). Since this hydrolysis reaction is reversible and the chemical equilibrium is markedly shifted towards aldimine, should proceed from the fact that in the absence of active amines groups partially or completely hydrolyzed only part alvinovich groups. The reaction of the isocyanate groups with gidrolizuemye alliminum groups do not have to go through the amino group. Needless to say, it is also possible reaction with the intermediate stages of hydrolysis. For example, it is possible to gidrolizuacy aldimine group in the form of polyamines directly reacted with isocyanate groups.

In addition, the composition includes isocyanatomethyl polyurethaneP. The term "polymer" refers here and throughout this document to a set of chemically identical but differ in the degree of polymerization, molecular weight and chain length of the macromolecules, which were obtained by polyreactive, as well as to derive such a set of macromolecules from polyeucte, i.e. to compounds, which were obtained by reactions, such as, for example, addition or substitution of functional groups of the above macromolecules and which may be chemically identical or chemically reading is unchanged. The term "polyurethane polymer" includes all polymers that are obtained by the method of diisocyanate polyaddition. It also includes polymers which almost do not contain or not contain urethane groups, such as simple polyetherurethane, complex polyetherurethane, simple palifermin, polyurea complex palifermin, polyisocyanurate, polycarbamide etc.

The term "predecessor synthetic material" in this document are indicated Monomeric, oligomeric or polymeric organic compounds (or homogeneous or heterogeneous compositions containing such compounds), which are contained in them available for polyreactive active groups capable, alone or together with other molecules to react with the formation of high-molecular synthetic material, organic polymers - a process that is commonly called "hardening" or "curing", regardless of whether taking place during the curing reaction to covalently or otherwise crosslinked structures.

The concept of "polyreactive" includes all types of reactions polyaddition, polycondensation and polymerization.

Polyurethane polymerPobtained by reaction of at least one polyol with at least one polyisocyanate. This is aimogasta can be bringing in the usual way polyol and a polyisocyanate in the reaction, for example, at temperatures from 50°C to 100°C, possibly with the addition of suitable catalysts, the polyisocyanate is dosed so that its isocyanate groups were in stoichiometric excess relative to the hydroxyl groups of the polyol. Excess MDI is selected so that the resulting polyurethane polymerPafter all react the hydroxyl group of the polyol, the content of free isocyanate groups remained equal, for example, 0.1 to 15 wt.%, in particular 0.5 to 5 wt.% in the calculation for the entire polyurethane polymerP. Perhaps polyurethane polymerPcan be obtained by the additional use of plasticizers, and used plasticizers do not contain active isocyanate groups.

These polyols have an average molecular weight 250-30000 g/mol, in particular 1000-30000 g/mol and an average OH functionality in the range from 1.6 to 3.

Additionally these these polyols in obtaining polyurethane polymer Pcan be used a small amount of low molecular weight two - or polynuclear alcohols, such as 1,2-ethanediol, 1,2 - and 1,3-propandiol, neopentylglycol, diethylene glycol, triethylene glycol, isomers of dipropyleneglycol and dipropyleneglycol, isomers of butanediol, pentanediol, hexanediol, heptanediol, octanediol, nonanediol, decanediol, undecanol, 1,3 - and 1,4-cyclohexanedimethanol, hydrogenated bisphenol A, dimeric fatty alcohols, 1,1,1-trimethyloctane, 1,1,1-trimethylolpropane, glycerol, pentaerythritol, sugar alcohols like xylitol, sorbitol or mannitol, sugars as sucrose, other higher alcohols, low molecular weight products alkoxysilane the above two - and polynuclear alcohols, and also mixtures of the aforementioned alcohols.

As polyisocyanates to obtain such isocyanatobenzene polyurethane polymer used monomers or oligomers two - or polynuclear isocyanates, which were listed as polyisocyanatesDsuitable for receiving eliminatorias the compounds of formula (I). As polyisocyanates are suitable, in particular, MDI, HDI, TDI and IPDI.

As described above, present in the composition eliminatorias compound of formula (I) can be obtained separately and introduced into the composition as it is. However, it can also be obtained in situ, i.e. in the course of obtaining the composition, t is m, what is a suitable amount of at least one aldimine formula (XI) and at least one MDIDresult in reaction in situ, i.e. in the presence of other components of the composition. When the polyisocyanateDpreferably is isocyanatomethyl polyurethane polymerPwhat has been described in detail above.

Typically eliminatorias compound of formula (I) is present in an amount of from 0.1 to 30 wt.%, preferably from 0.5 to 20 wt.% and, in particular, from 1 to 10 wt.% in the calculation of the composition.

For the case when eliminatorias compound of formula (I) is a heterofunctional, its content can be more than 30 wt.%. In this case, its content may also reach almost to 100 wt.%, since this composition by adding water crosslinks. This occurs when m, q and p in the formula (I) are chosen so that m*p ≤ q.

Advantageously, if the composition, in addition to eliminatorias the compounds of formula (I) and a polyurethane polymer P contains at least one catalystKAT-1. As catalystKAT-1suitable compounds that are stable when stored together with isocyanate groups and which accelerate leading to the curing of the composition of the reaction of the isocyanate groups, in particular the reaction with alliminum groups, as well as moisture.

In addition, the composition may include polymers containing hydrolyzable organoalkoxysilanes groups, which are referred to herein as "wilanowie groups". As examples of such polymers containing silane groups, should include the following: the reaction products isocyanatomethyl polyurethane polymers with active isocyanates by organoalkoxysilanes, as, for example, mercaptoethylamine or aminoalkylsilane described, for example, in US 3632557, in particular, the reaction products isocyanatomethyl polyurethane polymers from the reaction products, joining Michael aminoalkylsilanes and esters of maleic or fumaric acid, as described, for example, in EP 0403921 B1; the reaction products of gidrauxilirovania polymers having terminal double bonds, in particular polyoxyalkylene polymers with allyl end groups, with al what oxirane, described, for example, in US 3971751 and US 6207766; the reaction products of polymers containing active hydrogen atoms, such as hydroxyl or mercaptopropyl, isocyanatobenzene described, for example, in US 4345053 and US 5990257; polymers containing 3-(N-celelalte)-aminopropanoic groups, which are the reaction products of polymers containing 3-oxopropionate group, with aminoalkylsilane described, for example, in WO 2004/056905 A1.

The composition can also contain polymers, which have both isocyanate and silane groups.

The molar ratio between alliminum and isocyanate groups in the composition is preferably of 0.1 to 1.1, preferably of 0.25 to 1.0, particularly preferably 0.5 to 1.0.

Composition was prepared and stored in the absence of moisture. In a suitable airtight container or layout, as, for example, in a barrel, bottle or cartridge, it has excellent storage stability. In this document the term "stable storage" and "storage stability" in connection with the composition indicated condition, when the viscosity of the composition under suitable storage for the considered period of time does not change or changes only so that the composition remains applicable as defined.

Described composition is suitable as a synthetic precursor of the mother of the La.

If the composition is brought into contact with moisture, it solidifies with the formation of high molecular weight polyurethane polymer. Thus, the composition is a moisture curing and is called one-component moisture curing composition. Curing is based on the combination of different reactions of hydrolysis, addition and condensation between contained in the composition of the reactive groups, namely alliminum groups and isocyanate groups, and also the audience may wilanowie groups. Aldimine groups hydrolyzed to formally amino group and quickly react with isocyanate groups to form urea groups. Isocyanate groups react with each other with formation of urea groups and silane groups react with each other with the formation of siloxane groups. The reaction between gidrolizuemye alliminum groups and isocyanate groups is faster than the reaction of isocyanate groups with each other, and proceeds to complete or almost complete disappearance alvinovich groups. This gidrolizuacy aldimine do not need to react with isocyanate groups in the fully hydrolyzed form, i.e. as amino groups, but can also react with the isocyanate groups in the partially hydrolyzed form, for example, in the de pollinating groups. In addition to the moisture curing compositions contribute and also other factors, such as intense heat, for example, from 80 to 200°C, or UV radiation, or a combination of these factors.

Provided that there is enough moisture, the composition cures rapidly and completely to essentially non-adhesive mass. Curing proceeds without formation of bubbles, as the isocyanate groups are partially or completely reacted with gidrolizuemye alliminum groups, and therefore produced little CO2or not formed. Curing is accelerated in the presence of catalysts, for example the above-mentioned organic carboxylic acids or sulfonic acids, for additional hydrolysis alvinovich groups, without causing the formation of bubbles. The moisture required for curing may take from the air (air moisture), and the composition is cured by diffusion of moisture from the outside in. However, you can also bring the composition into contact with the aqueous components, for example, by lubricating, for example, a polishing agent, by spraying or by immersion, or can be added to the aqueous composition components, for example, in the form of aqueous paste, which, for example, homogeneous or heterogeneous mixed with the composition in a static mixer.

Due to the absence of odor in Aldini the containing compounds of formula (I), composition before, during, and after curing has no smell. Thus, it can also be used in applications involving no smell, as, for example, for bonding, sealing, coating or lining inside vehicles or buildings.

The composition can be used for different purposes as a predecessor of synthetic material. In particular, it is suitable for use as an adhesive for bonding different bases, for example, for bonding of structural parts in the manufacture of motor vehicles, rail vehicles, ships or other industrial objects as different kinds of sealants, for example, for sealing joints in building constructions, as well as a coating or cladding for different products or different bases. As preferred coatings protective paint, varnish coating and the protective coating. From facing as preferred, it should be mentioned, in particular, flooring. Such facings get what the song is usually poured on the ground and level, where it cures to receive flooring. For example, these flooring are used for offices, residential premises, hospitals, schools, warehouses, automotive garages, and other private or industrial applications. As these applications have a place in the big PLO is Adah, the already paltry selection of substances from the deck leads to problems with health and/or smell, even if we are talking about applying on the open areas. Of course, a large part of the flooring is put in the interior, making small education smell is of special significance.

In one preferred embodiment, the implementation of the described compositions are applied as an adhesive or sealant.

When applied as an adhesive composition is applied on the basis ofS1and/orS2. Thus, the adhesive may be applied to one or the other, or on both bases. Then glued the parts together, then glue cures. Thus it is necessary to ensure that the connection parts took place during the so-called open time, to ensure that both the joined parts securely glued with each other.

When used as a sealant composition is applied between the bases of theS1andS2and then there is a cure. Usually sealant presoviet in the seam.

In both applications the basis ofS1and the basis ofS2may be the same or different.

Suitable basesS1orS2are, for example, inorganic bases such as glass, glass ceramic, concrete, mortar, brick, tile, plaster and natural stone such as granite or marble; metals is whether the alloys, as aluminum, steel, nonferrous metals, galvanized metals; organic bases, such as wood, synthetic materials, such as PVC, polycarbonates, PMMA, polyester, epoxy resins; coated with the basics, such as metals or alloys with a dusting powder; and also paints and varnishes, in particular automotive lacquers.

It is possible to apply adhesive or sealant, the basics can be pre-processed. This pre-processing includes, in particular, the processes of physical and/or chemical cleaning, such as grinding, sandblasting, brushing or the like, or processing cleaners or solvents, or the application of the adhesion promoter, the solution of the adhesion promoter or primer.

By "primer" herein means a composition suitable as a primer, which in addition to inactive volatile substances and optional solid additive contains at least one polymer and/or at least one substance with reactive groups and which is capable, when applied to the base to harden to a solid film having good adhesion with the layer thickness of typically 10-15 μm, and curing is carried out either by evaporation inactive volatile substances, such as solvent or water, or through chemical reaction, or by a combination of these factors, and Kotor which forms a good bond with done next layer, for example with glue or sealant.

The adhesive or sealant is preferably uniformly. The coating composition can be carried out in a wide temperature range. For example, the composition can be applied at room temperature, which is typical for elastic adhesive or sealant. However, the composition can also be applied at lower or higher temperatures. The latter is advantageous especially when the composition contains a highly viscous or fusible components which are usually present in the hot melt adhesives, for example, in a moderately hot melt (Warm-Melt and hot melt (Hot Melt) adhesives. Temperature mapping for moderately hot melt adhesives are, for example, from 40 to 80°C, and melt - from 80 to 200°C, in particular from 100 to 150°C.

After bonding or sealing of the fundamentalsS1andS2using the compositions have glued or sealed product. This product can be a structure, in particular ground or underground structure, or vehicle, for example, water or land vehicle, in particular a car, bus, truck, train or ship, or any part thereof.

In particular, if the composition is used as an adhesive for elastic bonding, it preferably has a pasty consistency with strukturnovyazkikh properties. This adhesive is applied on the basis of the approach is Asim device, preferably in the form of tracks that may be essentially circular or triangular cross-section. Suitable methods of applying the adhesive are, for example, application of the standard cartridges, which are manually or which operate on compressed air, or the application of barrels or tin containers with a pressure pump or extruder, possibly with the help of a robot for the application. Adhesive with good characteristics of the coating has a high resistance and a short ductility. This means that after the application saves the marked form, i.e. does not spread, and after a stop device for applying no or very short filaments, so that the basis is not contaminated.

The composition has a high early strength. For application, in particular as glue this means that the adhesive connection before full curing may to some extent be able to withstand that in industrial production, for example in car Assembly, has a great advantage, because the pasted items are already in a relatively short time due to the bonding can be installed in place and thereby bonded object can be moved without additional fixing and continue processing.

The composition in the cured state has a superb properties. For example, it has high is some elasticity and high tensile strength tensile. Its modulus of elasticity varies depending on the components used to produce compositions, such as polyols, polyisocyanates or polyamine, and can be installed in accordance with the requirements of the particular application, for example, high values for glue or low values for the sealant. Its adhesion to different bases is great that because of the rapid curing it is not taken for granted, since, according to experience, fast curing compositions are often too poorly prone to the formation of the clutch. With regard to resistance to the effects of aging, such as heat, sunlight or UV radiation, moisture, steam or the influence of chemicals, there are no deviations from the behavior typical of isocyanatomethyl polyurethane polymers in dry condition.

Composition (precursors of synthetic material)

Examples 1 to 7 and example 8 (comparison)

Each sample was weighed 100.0 g of polyurethane polymerPPI, the receipt of which is described below, in a polypropylene Cup with screw cap and placed in an atmosphere of dry nitrogen. To this was added 0.3 g of a solution of salicylic acid (5% wt. in dioctyladipate)and specified in table 1 aldimine formula (XI) in the specified amount, the mixture was thoroughly stirred using a centrifugal mixer (SpeedMixer™ DAC 150, FlackTek Inc.), immediately thereafter poured into an interior coated with varnish aluminum tube and sealed it closed. The number of added aldimine formula (XI) in all the examples corresponds to the ratio between the isocyanate groups in the polyurethane polymer and the amount of the reactive groups (aldimine group plus amino or hydroxyl group) in aldimine 1.0/0,7.

Polyurethane polymerPP1produces the following way:

1300 g of polyoxypropylene (Acclaim®4200 N, Bayer; OH number 28.5 mg KOH/g), 2600 g polyoxypropyleneamine polyoxyethylene (Caradol®MD34-02, Shell; OH number of 35.0 mg KOH/g), 605 g of 4,4'-etilendiamindisuktsinatov (MDI; Desmodur®44 MC L, Bayer) and 500 g of diisodecylphthalate (DIDP; Palatinol®Z, BASF) were brought to reaction at 80°C with the formation of the polyurethane polymer with terminal NCO groups and a content of free isocyanate groups 2,07% wt. and a viscosity at 20°C 48 PA·S.

Obtained composition was tested for stability during storage, during the formation of crusts, blisters, odor and mechanical properties after curing.

The storage stabilitywas determined from the change in the viscosity when stored in warm. For this purpose, the predecessor of the synthetic material in a closed tube was kept in an oven at 60°C and measured its viscosity for the first time in 12 hours, and the second time after 7 days of storage. The storage stability is expressed through the percentage increase of the second viscosity values compared to the first.

The results are given in table 1.

Obtained in this way, the adhesives were tested at the time of formation of a crust, the smell, the mechanical properties after curing and adhesion to glass. The results are given in table 6.

The shore hardnesswas determined according to DIN 53505.

Testing the tensile strength of the tensile and shear for each dimension corresponding 2 glass plates with a thickness of 6 mm, a width of 25 mm and a length of 75 mm float glass; firm Rocholl, Schönbrunn, Germany) was pre-treated with Sika activator®(available in sale Sika Shweiz AG). After drying for 10 minutes the plate using a suitable form of PTFE was set relative to each other with a vertical distance of 5 mm so that they overlap in the head part 10 mm Region of overlap between the plates was filled with adhesive, and the adhesive was activated on the sides of the plates. The glue was utverjdala within 7 days at 23°C and relative humidity of 50%, then use the machine for tensile test was determined breaking strength at a constant shear rate of 20 mm/min according to DIN EN 1465. The values shown are the average of three measurements.

Adhesion to glass was determined by the picture of a break on the test samples used for determination of ultimate strength in tension and shear after the test. Gap, cohesive 100%, that is trapped completely in the glue, it was estimated by the value "1", and cohesion at 0%, then there is a gap that occurred entirely between the surface of the glass and glue and adhesive which, it was estimated by the value "5". Adhesion with the values of cohesive rupture less than 75% was regarded as unsatisfactory.

Other tests were carried out as described in example 1.
