The area of technical applications

The present invention relates to preventing pollution of the composite material, which almost never happens deposits from airborne particles of matter composed of tiny particles (like dirt, dust, sand dust or pollen)or liquid substances (a type of soy sauce, coffee or juice), or such material which easily removes airborne particles or liquid substances, even if their deposition on the material.

Background of invention

In recent years, serious social problem became allergic diseases caused by suspended substances like pollen, cedar, dead mites, fungal spores or house dust. Airborne particles are easily deposited on the clothing or the filter of the air conditioner. Therefore, particles of a substance deposited on clothing and filters, in turn, can get away from them, polluting the environment in the room. In addition, these particles reduce the suction power or the ventilating capacity of the filter cleaning devices or fans.

Suspended particles tend to be deposited on the fibrous structures with a complex structure, including a rough surface and emptiness. Further, since the pollen of cedar of Joutsenniemi, it is easily deposited on the fibrous structures. Thus the cedar pollen is able to easily penetrate into the accommodations. The filters of air conditioners and plating, as well as fans or air purifiers, having nodes from molded plastic, the friction charging. Therefore, it is well known that airborne particles are deposited on these sites and are a major cause of pollution and deterioration of the work.

In addition, the deposition on clothing, Wallpaper or carpets liquid substances (a type of soy sauce, coffee or juice) may cause staining or the appearance of mold, which, in turn, produces fungal spores. In addition, after the above liquid dry matter contained in components that are able to precipitate in the air, polluting the internal environment.

As preventing pollution (hereinafter also referred to as dust) methods of preventing the deposition of "hard dirt" (such as litter or dust), it was recently proposed fiber, which almost never happens deposition of pollen, cedar, or such treatments, which prevent precipitation of the specified pollen. Examples of such fibers include fabric, treated with special detergents containing nonionic antistatic agent; silica Sol that contains kolloidn the th silica, modified aluminum silicate, and an aqueous emulsion of polyethylene (see, for example, patent document 1); fiber-based pulp, which precipitated fine particles of aluminum oxide with a size of 1.0 μm or below, or fibers based on cellulose, impregnated with fine particles of aluminum oxide (see, for example, patent document 2); and a fibrous structure, the treated colloidal silica, and technical liquid containing resin on the basis of glyoxal, or a silicone resin (see, for example, patent document 3).

Processing service, Wallpaper or carpet to be water-repellent is usually done as a way to prevent pollution and designed to prevent deposits of liquid dyes (a type of soy sauce, coffee, juice, oil, dirty water or blood), and solids (type of litter or dust). Examples of water-repellent means include aqueous solutions containing acrylate or methacrylate, each of which has an alkyl fluoride group and alkoxysilane a crosslinking agent (see, for example, patent document 4); technical liquids containing alkoxysilane and modified alkyl silicone oil, dispersed in an organic solvent (see, for example, patent document 5); and compositions containing compounds of phosphoric acid, including performanceline group of thermoplastic resin or thermosetting resin (see, for example, patent document 6). These compositions to be applied on the fiber surface (such as clothing or carpet) to give her property to prevent pollution.

The increase in the content of the binder component 4 can lead to an increase in the strength and durability of the layer of the fine inorganic particles 10. However, if the content of the binder component 4 (such as a vinyl monomer with unsaturated bonds; silane monomer with unsaturated bonds; acrylic monomer containing performanceline group; a crosslinking agent based on silane containing performanceline group; unsaturated polyester, unsaturated acrylic; epoxyacrylate; urethaneacrylate; acrylate esters; an acrylate ethers; polybutadiene; silicone acrylate; maleimide or oligomer type Poliana/politial) above 40 wt.% from the content of the inorganic fine particles 2, the increase in the specific surface area of these particles contributes to the electrification of the surface.

Electrification reports besieged and airborne particles solids dust-and the ability to separate, due to the electrification of origin is it also coagulation of inorganic fine particles 2. Coagulation of small inorganic particles 2 causes many defects such as small holes in the layer of fine inorganic particles 10. If the content of the binder component 4 below 0.1 wt.% from the content of the inorganic fine particles 2, the layer of fine inorganic particles cannot be reliably fixed to the substrate 1, resulting in insufficient durability. Thus, to improve wear resistance (assuming dust protection and the ability to separate yourself from the dust) it is preferable that the content of the binder component 4 ranged from 0.1 wt.% up to 40 wt.% from the number of small inorganic particles 2.

Introducing the option for preventing contamination of a composite material containing hydrophobic or mesonephroma substance (such fluorinated compounds), representing at least part of the binder component. The specified binder component containing a fluorinated compound, randomly located on the surface of fine particles, showing low concentrations hydrophobicity or melaniemadisont. In addition, the presence of a very small volume of space through which can pass electrons, makes it difficult for the electrification by friction, preventing, thus, the deposition of suspended in the hcpa is heh particles (type a dirt dust or pollen) or the deposition of liquid substances (a type of soy sauce, coffee or juice). Consequently, it is possible provision preventing pollution of composite material having wide practical application.

According to the presented variant of the binder component 4 are distributed on the surface of the inorganic fine particles 2 coated with celanova monomer 3, at random intervals. Therefore, the amount of the binder component 4 can be reduced. In addition, the binder component 4 shows the hydrophobicity or melaniemadisont. By replacing part of the binder component 4 substance that possesses antimicrobial, antiviral, anti-allergic and/or antithrombotic properties that could be provided to prevent contamination of the composite material a variety of actions, while not deteriorating the dust-and the ability to separate yourself from the dust, and property, prevent pollution (type, hydrophobicity and massenproteste).

Next will be described a method of chemical compound substrate 1 with a solution containing fine inorganic particles with the silane monomer and the binder component 4. In the present embodiment, the chemical bond is preferably formed during the graft copolymerization.

According to the variant example of the graft copolymerization prepyatstvuyushchego the pollution of the composite material 100 is a graft copolymerization in the presence of peroxide catalyst, graft copolymerization using heat or light energy, and graft copolymerization with the use of radiation (radiation polymerization).

Of these processes on the principles of ease of polymerization and performance is the most appropriate radiation polymerization. Examples of the radiation used in the graft copolymerization include α-, β-, and γ-irradiation, irradiation with electron beam, and UV-irradiation. In the present embodiment, particularly suitable are γ-irradiation, irradiation with electron beam and UV radiation.

According to the presented option prevents contamination of the composite material 100 is obtained by graft copolymerization method as follows.

The following describes the first method for the specified option. First to disperse solution containing inorganic fine particles 2, chemically related to celanova monomer 3, add a binder component 4. After sufficient stirring the obtained solution is applied to the selected surface of the substrate 1 (the polymer surface). If necessary, the solvent is removed, for example, by heating. Then the surface of the substrate 1, on which is applied inorganic fine particles 2, chemically related to celanova monomer 3, irradiated and is the source of the radiation (like gamma radiation, irradiation with electron beam or UV irradiation). When this happens as graft copolymerization silane monomer 3 with the surface of the substrate 1, and the chemical binding of the inorganic fine particles 2; this process represents the simultaneous radiation graft copolymerization.

Hereinafter is described a second preferred method presented. Previously the surface of the substrate 1 is irradiated by the radiation source (of type γ-irradiation, irradiation with electron beam or UV irradiation). The binder component 4 is added to the dispersion solution of the inorganic fine particles 2, chemically related to celanova monomer 3. Sufficiently mixed solution is applied on the surface of the substrate 1 in order to perform both the interaction of the silane monomer 3 and substrate 1, and the chemical binding of the inorganic fine particles 2; this process is a simultaneous pre-radiation graft copolymerization.

In the present embodiment, as described above, preventing contamination of the composite material obtained by the introduction of the binder component 4 in the dispersion solution of the inorganic fine particles 2 and the subsequent application of a sufficiently mixed solution to the surface of the substrate 1.

Dispersion liquid of fine reorganizes is their particles 2 can be applied in a standard way: coating methods centrifugation, dipping, spraying, pouring, coating, removing the excess with a strap, coating using a special device with grooved microsilica or device with a grooved roller. Partially dispersion liquid of the inorganic fine particles 2 can be applied using screen printing, offset printing, dry offset printing, flexo printing, inkjet printing or by any other suitable method.

In order to effectively and homogeneous graft copolymerization silane monomer 3 the surface of the substrate 1 is first subjected to the hydrophilic treatment (such as corona treatment, plasma discharge processing, processing, flame or chemical treatment with aqueous solutions of oxidizing acids (type oil emulsions recovery or perchloro acid) or an alkaline aqueous solution containing sodium hydroxide.

As described above, according to the presented option prevents contamination of the composite material 100 includes a substrate 1, having a polymer surface, and mounted on the specified substrate layer 10 fine inorganic particles. This layer 10 fine inorganic particle includes a binder component 4 and the inorganic fine particles 2 coated with celanova monomer with unsaturated bonds. The content of the binder component 4 is 0.1 mA is.% up to 40 wt.% from the number of small inorganic particles 2. The binder component 4 are distributed over the surface of these fine particles 2 coated with celanova monomer 3, uniformly at random intervals. Thus, according to the presented option to prevent pollution of the composite material 100 is able to prevent the deposition of airborne fine particles (type dirt, dust, sand or pollen) or the deposition of liquid substances (a type of soy sauce, coffee, juice or salad oil). Even if their deposition on preventing pollution of the composite material 100 has occurred, the material has a high capacity to the Department that allows easy removal of airborne particles.

In addition, the silane monomer 3 with unsaturated bonds, chemically active with respect to the substrate 1, is associated with the surface of the inorganic fine particles 2 by condensation with dehydration. These inorganic fine particles 2 is fixed on the substrate 1 by combining unsaturated bonds linking the surface of the inorganic fine particles 2, or through the interaction of unsaturated bonds linking the surface of the inorganic fine particles 2 with the polymer surface of the substrate 1. There is also a binder component. Thus, according to the presented variant in preventing for who to raneniyu composite material 100 inorganic fine particles 2, covered celanova monomer 3, firmly connected together, and these inorganic fine particles 2 is also strongly coupled with the substrate 1. Preventing the contamination of the composite material 100, thus, capable of a long period of time to be very high dust-proof properties, and very high protivotarannymi action.

Further, according to the presented variant, if a portion of the binder component 4 on the surface of the inorganic fine particles 2 coated with silane monomer 3, to replace the substance with antimicrobial, antiviral, anti-allergic and/or antithrombotic properties, preventing contamination of the composite material can easily purchase these options, it does not deteriorate its dust-and the ability to separate yourself from the dust, and property, prevent pollution (type, hydrophobicity and massenproteste).

In addition, according to the presented variant of the inorganic fine particles 2 can be firmly fixed to the substrate 1 by chemical bonds 5. Thus, after the product form given by molding or manufacturing process, the inorganic fine particles 2 can be fixed to the substrate 1. Therefore, the presence of the inorganic fine particles 2, possessing the x different functions, does not impair the formation.

Further, inorganic fine particles 2 may be formed from a monolayer of particles, or a laminated layer on the substrate, having a form of a film, a polymer plate, fiber or fabric. Thus, the inorganic fine particles 2 are not impair the texture of the substrate. Therefore, according to the presented option to prevent pollution of the composite material may find application in a variety of applications.

In the present embodiment, the substrate may have given the appearance (shape, size, etc.) type film, fiber, fabric, mesh or honeycomb. Therefore, there is a wide variety of substrates can be dust tight.

Presents can be applied to various products, such as agricultural materials (type films for greenhouses and film for passes in greenhouses), construction materials (type of materials for the exterior walls, window frames, doors and protective glasses; materials for interior decoration, such as the Wallpaper, carpet and plastic tiles), shoes, clothing, female toilet, hosiery products, gloves and shoes; bedding accessories (like pajamas, mattresses, sheets, pillows, pillowcases, blankets, towels, quilts and duvet covers for them); caps and hats; handkerchiefs; towels; carpets; ø the oram; filters for air purifiers; air conditioners; fans; vacuum cleaners and household fans; the electrodes and separators for fuel cells; mosquito nets; screens for screen printing; to the components, which tends biological pollution (types of marine vessels, onshore facilities, canned fish, fish nets, buoys, holes for water extraction, water purification filters).

The evaluation of the properties

Property dust protection: For testing were cut samples of size 10 cm × 10 cm on Top of each sample according to JIS Z 8901 were evenly scattered KANTO loam, quartz sand or mixed dust. The weight of samples was measured before and after deposition of dust.

Wettability: the wettability of the surface represents the unit's ability to prevent contamination. On the composite material drops caused 2 μl of distilled water. Boundary angle drops were measured on the analyzer interface solid - liquid, was used for this analyzer DropMaster 300 manufactured by Kyowa Interface Science Co., Ltd. Usually the boundary angle of greater magnitude is an indicator of a higher ability to prevent contamination in case of liquids (repulsion or fluid resistance to liquid dyes).

Electric potential due to friction: Test sample (10 cm × 10 cm) was Electrosoul by friction feather duster to remove dust. Electrostatic potential was determined by measuring static electricity (SV-73A produced by Nippo Static Co., Ltd.)

Durability dust-proof properties: the test sample was rinsed with technical movements of the lips forward and back 10 times under a 100 g load. Change dust protection was determined as a measure of durability. For comparative examples 2, 3, 4 and 5 test the durability was not conducted because the original properties of the dust protection were low.

"80>" in table 2 indicates that the boundary angle is equal to approximately less 80°.

From table 1 it is seen that in the test for durability in the case of example 1, containing a binder component 4, the mass deposited on the sample to be tested is mixed dust remained virtually unchanged, indicating that the conservation properties of dust protection. In comparative example 1, there was a significant difference in the mass deposited on the sample to be tested is mixed dust; this indicates, is that the dust fell. The results obtained demonstrate that the addition of the binder component 4 increases the durability dust protection.

In comparative example 2, which included 50 wt.% the binder component 4, due to electrification by friction has not been demonstrated nor the properties of the dust protection, no otdelimosti dust. Examples 1-8, in which the content of the binder component 4 ranged from 0.1 wt.% up to 40 wt.%, showed property dust protection. The results show that if the content of the binder component 4 is from 0.1 wt.% up to 40 wt.% regarding the number of small inorganic particles 2, preventing contamination of the composite material 100 has a very high dust tight, very high properties otdelimosti dust, as well as sufficient for practical purposes durability.

In examples 2, 3, 5, 6, 7 and 8 as a binder component 4 is used hydrophobic or mesonephroma substance. These examples show that even if the content of the binder component 4 is low, it is approximately 15%, the boundary angle for water and the test sample is 100° or higher, have demonstrated high hydrophobicity. This assumes that the test sample has the property to prevent pollution, prevent Rasa deposition on liquid chemicals (type of juice or soy sauce). In addition, the friction does not cause electrification. This indicates that the test sample has a dust-proof properties.

In contrast, non-woven material made of polyethylene terephthalate (PET) of comparative example 4, as well as non-woven fabric of polytetrafluoroethylene (PTFE) of comparative example 5 were hydrophobic, but the friction has acquired an electric charge. In addition, they have no dust.

Further, in examples 2, 3, 5, 6 and 7 changes precipitated on the test samples of the mixed mass of dust, which is a measure of durability, differed slightly from the original properties of dust protection. Thus, the use of hydrophobic or mesonephroma substance as a binder component 4 capable of preventing contamination of a composite material with high durability. Even if airborne particles or liquid substances deposited on preventing pollution of the composite material, these airborne particles or liquid substances can be easily removed with this material.

In addition, various durability in example 7 and example 8 shows that consolidation of small inorganic particles by graft copolymerization increases durability.

As a show of rezultatefinale, regarding the durability, since the binder component 4 has an unsaturated group (type vinyl groups, epoxy groups, steriley group, metallinou group, akilattirattu, isocyanate group or alkoxygroup)representing such a position, which can be chemically linked to an active group of the silane monomer 3, located on the inorganic fine particles 2, the composite material has a very high dust tight, very high ability to separate yourself from the dust, and durability sufficient for practical use. Fabric containing a blend of 65% polyester and 35% cotton, which is usually used for lining or protective coating was applied as a serial product. The fabric treated as described in example 3 (2) and shown in figa, drops put soy sauce. Drops instantly spread through untreated tissue (pigv) and stained it. On the contrary, the treated fabric drops did not change its shape (figa), and after their immediate removal from the tissue with no her coloring was not saved.

As one of the commercially available filters used sieve for flour milling, which were processed according to the present invention. Wheat flour was sifted through the sieve, as shown in figa. A cell made of 62 μm n is Ilona 66 main yarn and 80 μm nylon 66 weft yarn (NBC Inc., NXX7), processed as described in example 4 (1). This cell is secured on a square frame, the internal dimensions of which was 200 mm × 200 mm, resulting in a sieve. The sieve set in vibration setting. After 600 g wheat flour dropped out, the sieve was removed, and light strikes have removed all the flour, remaining on the sieve (figa). Through a sieve of untreated cells after it has been sifted 500 g wheat flour, was able to pass a small amount of flour. In the light taps on the sieve wheat flour has closed almost all of its holes (pigv).

Mosquito mesh 50 mesh, is woven from 100 microns of polyester staple fibres, processed as described in example 4 (4). On top of this grid sprinkled cotton fluff, as shown in figa. After the cotton fluff was sprinkled on the horizontally disposed mosquito net, placed vertically and tapping tried to remove the cotton fluff (figa). In the case of untreated mosquito nets to remove the Pooh was hard, and he remained in the cells of this grid (pigv).

As a separate object you can use building materials, such as metals, wood, ceramics and plastics. The surface of building materials is often painted, coated with polymers or laminate type polymer film. As a note the RA construction material was used polymeric fluorocarbon film thickness of 50 μm (Asahi Glass Co., Ltd., ETFE film, Aflex 50 N), the film was processed as described in example 1(3). On top of this film sprinkled mixed with dust, as shown in figa. After mixed dust (corresponding to the conditions of JIS Z 8901) was sprinkled on the horizontally disposed film, placed vertically and tapping tried to delete a mixed dust (figa). In the case of a raw film to remove dust was hard, and she remained on the film (pigv).

As a material for interior decoration was selected commercially available polyester fabric for curtains, it was processed as described in example 1(3). On top of this fabric sprinkled mixed with dust, as shown in figa. After mixed dust (corresponding to the conditions of JIS Z 8901) was sprinkled on the horizontally disposed fabric, picked it up and tapping tried to delete a mixed dust (figa). In the case of raw cloth to remove dust was hard, and she remained on the specified tissue (pigv).
