Gluing method

FIELD: chemistry.

SUBSTANCE: method involves applying a UV curable adhesive resin composition, containing a photolatent base, onto at least one transparent surface of at least one of a first and a second substrate. The substrates are then brought together so that said adhesive composition lies in between. The adhesive composition is then exposed to actinic radiation for curing. The UV curable adhesive is a OH/NCO system or SH/NCO system. In another version of the gluing method, the first and second substrates are brought together after exposing the adhesive composition in between to actinic radiation.

EFFECT: disclosed gluing method enables faster curing of the adhesive.

The present invention relates to a method of bonding the first substrate with the second substrate using the radiation-curable adhesive composition comprising votolatino base.

Finding the right balance between stability education and reactivity at low temperature outdoors is an important task for most adhesive systems.

For two-component adhesives are usually based on the NCO/OH, NCO/SH and epoxides/amines have had, for curing in a short period of time at low temperature requires the addition of the catalyst, which reduces the viability of composition.

For one-component adhesives are usually based on epoxides or Blagodatnaya the isocyanates, it is also necessary the presence of a catalyst to accelerate the curing at a low temperature, which is also characterized by a significant disadvantage in deterioration of the stability of the composition. Other songs one-component adhesives, such as cyanacrylate or modified silane polymer, also interact with the water environment, which leads to low stability of the compositions.

Anaerobic adhesives, usually containing small amounts of peroxide and accelerator, remain liquid until they interact with atmospheric oxygen, but usually otverzhdajutsja a few cha is s when hit in an inert atmosphere or in the interaction with the metal surface. To eliminate premature gelation during storage vessel should half fill the air.

Curing UV adhesive systems react at room temperature after activation by light and remain stable in the dark. However, the curing partially suppressed dissolved and diffusing oxygen in the case of acrylates or they are sensitive to moisture in the case of epoxides. To date, the choice of curing UV-radiation groups limited to epoxy groups and double bonds.

Glue or plastisol must be processed at high temperature (120 to 240°C) before use, which limits their field of application substrates, which is resistant to heat.

In the European patent EP 898202 B1 (Ciba) described cured under catalysis by base composition containing alpha-aminoketone as a latent base, and their use in adhesives based on epoxy resins (see paragraph 0002). A suitable resin is, for example, polyacrylate containing 3-5% of carboxypropyl, and novolak epoxy-novolak (see example 1).

International application WO 01/923 62 (AKZO) refers to photoactivated composition coating containing at least one polyisocyanate and at least one compound containing isocyanate reactive groups of Isocyanate reactive groups include at least one Tilney group, and photoinitiation is votolatino basis. The compositions of the coatings are particularly suitable for use as transparent coatings, primer coatings, pigmented exterior coatings, basic coatings, primers and fillers. In WO 01/92362, apparently, does not contain assumptions about the use of any of such copolymers as an adhesive or glue.

In the International application WO 06008251 (Ciba) describes how to use votolatino base, in which the adhesive containing the specified catalyst is irradiated prior to use. However, its adhesive ability is not enough.

According to the invention it was found that irradiation after application leads to a faster cure.

In addition, diamino catalyst, usually contained in systems of OH/NCO or SH/NCO, you can replace the latent basis.

Thus, the present invention relates to a method of bonding the first substrate with the second substrate, which includes stages

a) applying a curing UV adhesive resin composition comprising votolatino base, at least one transparent surface, at least one of the specified first and second substrates;

b) combining the above first and second substrates located between the specified adhesive composition,

Another object of the present invention is a method of bonding the first substrate with the second substrate, which includes stages

a) applying a curing UV adhesive resin composition comprising votolatino base, on the surface,

b) irradiating the specified adhesive composition of actinic radiation to perform curing,

c) combining the above first and second substrates located between the specified adhesive composition.

Prepolymerisation adhesives containing isocyanate and a reactive group (protected or unprotected), for example, is treated at a high temperature and is applied on a substrate in accordance with the technology of thermocline, and then spend the complete curing with additional stage curing held with participation of reactive groups, which is done by photoactivation votolatino catalyst (i.e. votolatino Foundation).

Hot melts are of interest as cured under pressure adhesives (APC) and is suitable for replacement of compositions based solvents, to the that are unsuitable from the point of view of environmental protection. Due to the high viscosity of flow of the hot melt adhesive may be carried out at high temperature. The composition proposed in the present invention contains a reactive group suitable for use as cross-linking means for the formation of a coating of hot melt adhesive, in which the cross-linking means enter into chemical reaction with functional groups of the comonomers (meth)acrylate APC. After applying the concentration limit to first sew or thermally, in accordance with the mechanism of double knitting, then RCL sew UV radiation. The stitching UV radiation is usually carried out using short-wave ultraviolet radiation in the wavelength range from 200 to 400 nm, depending on the UV photoinitiator. Such systems and techniques are described, for example, in US 2006/0052472.
