Description

  In the present invention, particulate allergen substances composed of fine particles such as pollen and mite carcasses are difficult to adhere, and even if they adhere, allergens contained in these substances can be inactivated, and have excellent antiallergenic properties and dust resistance. The present invention relates to a composite member having

  In recent years, various allergic diseases caused by floating substances such as cedar pollen, mite carcasses, mold spores, and house dust have become serious social problems. These particulate floating substances are likely to adhere to clothes and air conditioner filters, and this is a new cause of particulate contamination on clothes and filters and causing indoor environmental pollution. In a filter such as a machine or a ventilation fan, the suction power and ventilation capacity are reduced. These particulate floating substances are easy to adhere to a fiber structure having a complicated structure with uneven surfaces and voids, and cedar pollen has a protruding structure on its surface. Therefore, it is a major factor that brings cedar pollen into the room because it easily adheres to the fiber structure. In addition, air conditioner filters made of resin-molded members, their housings, fans for ventilation fans, vacuum cleaners, etc. are charged by friction, so particulate floating substances adhere to them and cause dirt and deterioration of product functions. It is well known that this is a major cause.

  Recently, as a countermeasure against cedar pollen, fibers and treatment methods that are difficult to attach cedar pollen have been proposed. For example, a fabric treated with a treating agent to which a silica sol containing colloidal silica modified with a nonionic antistatic agent and aluminosilicate and an aqueous emulsion of polyethylene (for example, see Patent Document 1), Cellulosic fibers (for example, see Patent Document 2) to which 1.0 μm or less of alumina fine particles are attached or impregnated, colloidal silicas and glyoxal resins, and fiber structures treated with a treatment liquid containing a silicone resin compound (for example, Patent Document 3).

In addition, methods for inactivating allergens have also been studied in the past, and methods for destroying with heat and ultraviolet rays, and methods for inactivating allergens with fibers and fiber treatment agents containing antiallergen agents have been proposed. . For example, a fiber product carrying a metal phthalocyanine that decomposes allergens by catalysis (see, for example, Patent Document 4), a filter carrying a proteolytic enzyme (see, for example, Patent Document 5), a phenolic hydroxyl group, and the like. And a fiber treatment agent using a water-insoluble polymer anti-allergen agent having, for example, Patent Document 6.

  However, the above-mentioned fabrics and fiber structures having dustproof properties and antiallergenic properties have the following various problems.

  For example, in the fabric described in Patent Document 1, since a nonionic antistatic agent, that is, a surfactant is added with an anti-adhesion function, the surfactant is washed away in laundry or outdoors where it rains. Therefore, it is difficult to maintain the effect of preventing pollen adhesion for a long period of time. Moreover, in the fiber product described in Patent Document 2, alumina fine particles are adhered and fixed to cellulosic fibers, and there is a problem that the type of fiber material is limited. Furthermore, the fiber structure described in Patent Document 3 is obtained by fixing colloidal silica on the fiber surface with a binder made of glyoxal resin, and depending on the resin component, it becomes easy to be charged, and particulate floating substances adhere. However, there are problems that the attached particulate floating substances are difficult to be detached.

  The fiber added with the allergen inactivating function also has problems such as long-term function maintenance and elution of the anti-allergen agent, so that a large amount of binder is used to keep the anti-allergen agent on the fiber surface as in Patent Document 5. Need. For this reason, the anti-allergen agent is buried in the binder, and the amount of the anti-allergen agent that can function on the binder surface has been limited. In addition, in order for the anti-allergen agent to efficiently exhibit its function, a hydrophilic polymer is often required (for example, Patent Documents 6 and 7), and the treated fiber is expected to be sticky and used. There has been a problem that the application is limited, and the amount of allergens that can be inactivated is limited due to the difficulty in detaching the adhering particulate floating substances.

  The present invention has been made to solve such a conventional problem. Inorganic particulates coated with a silane monomer are immobilized on a substrate, and an antiallergen agent is combined with this to form particulate floating. As a result, it was found that a composite member excellent in dustproof property that can easily be removed even if it adheres and that can inactivate allergens efficiently can be obtained.

  Below, the composite member which has antiallergenic property and dustproof property of embodiment of this invention is explained in full detail using a figure.

  FIG. 1 is an enlarged schematic view of a part of a cross section of a composite member 100 having antiallergenicity and dustproofness according to an embodiment of the present invention.

  On the outermost surface of the inorganic fine particles 2 of this embodiment, a silane monomer 3 having an unsaturated bond is aligned and bonded with the unsaturated bonds facing the outside of the inorganic fine particles 2 to form a coating. Since the silanol group at one end of the silane monomer 3 is hydrophilic, it is attracted to the surface of the inorganic fine particles 2 that are hydrophilic. On the other hand, since the unsaturated bond at the reverse end is hydrophobic, it tends to leave the surface of the inorganic fine particles 2. For this reason, the silanol group is bonded to the surface of the inorganic fine particle 2 by dehydration condensation, and the unsaturated bond is oriented outward.

  As a method for this, the silane monomer 3 is added to a solution in which the inorganic fine particles 2 are dispersed in an organic solvent in an amount of 0.01% to 40% by mass with respect to the mass% of the inorganic fine particles 2.

  Solvents used include lower alcohols such as ethanol, methanol, propanol and butanol, lower alkyl carboxylic acids such as formic acid and propionic acid, aromatic compounds such as toluene and xylene, ethyl acetate and butyl acetate, etc. Esters and cellosolves such as methyl cellosolve and ethyl cellosolve may be used alone or in combination.

  The inorganic fine particles 2 used in the composite members 100 and 200 having antiallergenic properties and dustproof properties of the present embodiment are used for production in a state dispersed in the silane monomer 3 solution described above. The inorganic fine particles 2 are dispersed by stirring and dispersing using a homomixer or a magnetic stirrer, pulverizing / dispersing using a ball mill, sand mill, high-speed rotating mill, jet mill, or the like, or using ultrasonic waves. Is called.

  In addition, the inorganic fine particles 2 are used in the manufacture of the composite member 100 having antiallergenic properties and dustproof properties in the state of a dispersed colloidal dispersion liquid or a dispersion liquid obtained by pulverization. The dispersion of inorganic fine particles 2 is obtained by adding silane monomer 3 to a colloidal dispersion or a dispersion obtained by pulverization, and then dehydrating and condensing silane monomer 3 on the surface of inorganic fine particles 2 while heating under reflux. After forming the coating composed of the silane monomer 3 by bonding by reaction, after adding the silane monomer 3 to the dispersion obtained by micronization by pulverization, or after micronization by pulverization by adding the silane monomer 3 The silane monomer is bonded to the surface of the inorganic fine particles 2 by a dehydration condensation reaction by solid-liquid separation and heated at 100 to 180 ° C., and then pulverized and crushed for redispersion.

  After adding the silane monomer 3 to the dispersion obtained by micronization by pulverization or by adding silane monomer 3 and micronizing by pulverization, solid-liquid separation and heating at 100 ° C. to 180 ° C. to heat the silane monomer 3 is reactively bonded to the surface of the inorganic fine particles 2, the mass ratio of the inorganic fine particles 2 to 0.01% by mass to 40% by mass of the silane monomer 3 (that is, the mass ratio of the inorganic fine particles 2 to the silane monomer 3 is 100: 0.01 to 40) is bonded to the surface of the inorganic fine particles 2, the bonding strength to the surface of the substrate 1 in which at least the surface of the inorganic fine particles 2 is made of resin is not a problem in practice.

  The anti-allergen agent 5 combined with the inorganic fine particle layers 10 and 20 of the present embodiment is added after the inorganic fine particles 2 are coated with the silane monomer 3. The anti-allergen agent 5 of this embodiment is a substance selected from at least one of the group consisting of an organic polymer compound and a plant extract. Examples of organic polymer compounds include polymer compounds having phenolic hydroxyl groups, polyphenols such as catechin and tannic acid, flavonoids, carotenoids, amphoteric surfactants, amino acids, polypeptides, and enzymes. In addition, if it is a plant extract, extracts obtained from bamboo shoots, bamboo, ginkgo leaves, tea leaves, cypress, bonito, bodaiju, yucca, moon peach, tea tree, eucalyptus, lemongrass, thyme, olive genus, genus privet There is. The anti-allergen agent 5 may be used alone or in combination of two or more.

  The content of the anti-allergen agent 5 contained in the inorganic fine particle layers 10 and 20 of the present embodiment may be added at 1% by mass or more with respect to the content of the inorganic fine particles 2 coated with the silane monomer 3. The higher the amount, the better the antiallergenicity. However, when the amount of the anti-allergen agent 5 is increased, the ratio of covering the surface of the inorganic fine particles 2 is increased, so that the surface is easily charged, and the dustproof property and the dust separation property of the adhering particulate floating substance are lowered.

  In particular, even when the content of the anti-allergen agent 5 contained in the inorganic fine particle layers 10 and 20 formed on the substrate 1 is as low as 1% by mass with respect to the content of the inorganic fine particles 2 coated with the silane monomer 3, It exhibits antiallergenic properties.

  FIG. 3 is a schematic diagram showing a state in which the silane monomer 3 and the anti-allergen agent 5 on the inorganic fine particles 2 are aligned and bonded. As shown in FIG. 3, when the silane monomer 3 on the inorganic fine particle 2 and the hydrophobic portion 5a of the anti-allergen agent 5 cause a hydrophobic interaction, the hydrophilic portion 5b of the anti-allergen agent having an anti-allergen function efficiently faces outward. Along with the uniform distribution in the inorganic fine particle layers 10 and 20, the anti-allergenicity is exhibited in a small amount.

  However, if the content of the anti-allergen agent 5 contained in the inorganic fine particle layers 10 and 20 is more than 20% by mass with respect to the content of the inorganic fine particles 2 coated with the silane monomer 3, it tends to be charged, and thus is dustproof. In addition, the reduction in dust separation becomes remarkable. When the dustproof property and dust separation property are lowered, the particulate suspended matter containing allergen is likely to accumulate on the surface of the member. As a result, the particulate suspended matter newly flying on the surface of the member does not come into contact with the anti-allergen agent, and the anti-allergen property does not function.

  Therefore, the range in which the antiallergen property can be exhibited while maintaining the dustproof property and dust separation property is the inorganic fine particle 2 in which the content of the antiallergen agent 5 contained in the inorganic fine particle layers 10 and 20 is coated with the silane monomer 3. Is 1% by mass or more and 20% by mass or less, preferably 3% by mass or more and 15% by mass or less, and more preferably 3% by mass or more and 10% by mass or less.

  Furthermore, when the inorganic fine particle layer 10 composed of the inorganic fine particles 2 and the anti-allergen agent 5 becomes thick, the inorganic fine particle layer 10 may be deteriorated due to cohesive failure depending on the stress of the inorganic fine particle layer 10 and the use environment. After coating the inorganic fine particles 2, it is preferable to add a binder component 6 together with the anti-allergen agent 5.

Examples of the binder component 6 include monofunctional, bifunctional, and polyfunctional vinyl monomers having an unsaturated bond, such as acrylic acid, methyl methacrylate, ethyl acrylate, n-butyl acrylate, 2-hydroxyethyl acrylate, acrylamide, and methacrylic. Amide, acrylonitrile, vinyl acetate, styrene, itaconic acid, trimethylolpropane triacrylate, pentaerythritol triacrylate, silane monomer having an unsaturated bond, Si (OR ₁ ) ₄ (wherein R ₁ is carbon number 1 As an example, tetramethoxysilane, tetraethoxysilane, or the like, R _2n Si (OR ₃ ) _{4 -n} (wherein R ₂ is a carbon number of 1 to 6 hydrocarbon group, R ₃ is an alkyl group having 1 to 4 carbon atoms, n represents an integer of 1 to 3 In addition, for example, methyltolylmethoxysilane, methyltriethoxysilane, dimethyldiethoxysilane, phenyltriethoxysilane, hexamethyldisilazane, hexyltrimethoxysilane, etc. An alkoxy oligomer or the like is used.

  Furthermore, as the binder component 6, an oligomer or a polymer such as unsaturated polyester, unsaturated acrylic, epoxy acrylate, urethane acrylate, polyester acrylate, polyether acrylate, polybutadiene acrylate, silicone acrylate, maleimide, etc. Is used.

  Further, as the binder component 6, stearic acid acrylate, reactive silicone oil, and reactive silicone oligomers such as Fresella D manufactured by Matsushita Electric Industrial Co., Ltd. are used as compounds exhibiting water repellency and oil repellency.

  Furthermore, as the binder component 6, as a substance having water repellency or oil repellency, an acrylic monomer having a perfluoroalkyl group, for example, 2- (perfluoropropyl) ethyl acrylate or 2- (perfluorobutyl) ethyl Acrylate, 2- (perfluoropentyl) ethyl acrylate, 2- (perfluorohexyl) ethyl acrylate, 2- (perfluoroheptyl) ethyl acrylate, 2- (perfluorooctyl) ethyl acrylate, 2- ( Perfluoronoryl) ethyl acrylate, 2- (perfluorodecyl) ethyl acrylate, 3-perfluorohexyl-2-hydroxypropyl acrylate, perfluorooctylethyl methacrylate, 3-perfluorooctyl-2-hydroxyl And pills acrylate, fluorine compounds such as 3-perfluorodecyl-2-hydroxypropyl acrylate are used.

  Furthermore, as the binder component 6, as a substance having water repellency and oil repellency, for example, 2-perfluorooctylethanol, 2-perfluorodecylethanol, 2-perfluoroalkylethanol, and perfluoro (propyl vinyl ether). Alternatively, fluorine compounds such as perfluoroalkyl iodide, perfluorooctylethylene, and 2-perfluorooctylethylphosphonic acid are used.

Furthermore, as the binder component 6, as a substance having water repellency or oil repellency, a silane coupling agent having a perfluoroalkyl group, for example, CF ₃ (CH ₂ ) ₂ Si (OCH ₃ ) ₃ , CF ₃ (CF ₂ ) ₅ (CH ₂ ) ₂ Si (OCH ₃ ) ₃ , CF ₃ (CF ₂ ) ₇ (CH ₂ ) ₂ Si (OCH ₃ ) ₃ , CF ₃ (CF ₂ ) ₁₁ (CH ₂ ) ₂ Si ( OCH _{3) 3 and, CF 3 (CF 2) 15} (CH 2) 2 Si (OCH 3) 3 _{and, CF 3 (CF 2) 7} (CH 2) 2 Si (OC 2 H 5) 3 and, CF ₃ (CH ₂ ) ₂ SiCH ₃ (OCH ₃ ) ₂ , CF ₃ (CF ₂ ) ₂ (CH ₂ ) ₂ SiCH ₃ (OCH ₃ ) ₂ , CF ₃ (CF ₂ ) ₅ (CH ₂ ) ₂ SiCH ₃ (OCH _{3) 2} Ya _{CF 3 (CF 2) 7 (} CH 2) 2 SiCH 3 (OCH 3) 2 _{and, CF 3 (CF 2) 7} (CH 2) 2 SiCH 3 (OC 2 H 5) 2 _and, CF 3 _(CF 2) ₇ (CH ₂ ) ₂ Si (OCH ₃ ) ₃ , CF ₃ (CF ₂ ) ₇ (CH ₂ ) ₂ Si (OC ₂ H ₅ ) ₃ , CH ₃ (CF ₂ ) ₉ (CH ₂ ) ₈ Si ( OC ₂ H ₅ ) ₃ , CF ₃ (CF ₂ ) ₇ CONH (CH ₂ ) ₃ Si (OCH ₃ ) ₃ , CF ₃ (CF ₂ ) ₇ CONH (CH ₂ ) ₂ SiCH ₃ (OCH ₃ ) ₂ An oligomer having a perfluoroalkyl group and a silanol group, for example, a fluorine compound such as KP-801M (manufactured by Shin-Etsu Chemical Co., Ltd.) or X-24-7890 (manufactured by Shin-Etsu Chemical Co., Ltd.) is used.

  The binder component 6 may be used alone or in combination of two or more.

  Here, the binder component 6 binds the inorganic fine particles 2 coated with the silane monomer 3 and the inorganic fine particles 2 and the substrate 1 to each other, and suppresses the inorganic fine particle layers 10 and 20 from being deteriorated due to cohesive failure or the like and peeling off. To be added. The binder component 6 includes a vinyl group, an epoxy group, a styryl group, a methacrylo group, an acryloxy group, a reaction site that can be chemically bonded to the reactive group of the silane monomer 3 that covers the inorganic fine particles 2. It is desirable to have an unsaturated group such as an isocyanate group or an alkoxy group as a molecular component.

  The binder component 6 may be added in an amount of 0.1% by mass or more with respect to the inorganic fine particles 2 coated with the silane monomer 3, and an improvement in durability can be expected as the addition amount increases. However, when the amount of the binder component 6 increases, the ratio of covering the surface of the inorganic fine particles 2 increases, so that the surface becomes easy to be charged, and the dustproof property and the dust separation property of the attached particulate floating substance are lowered.

  In particular, when the binder component 6 contained in the inorganic fine particle layer 10 formed on the substrate 1 is more than 40% by mass with respect to the inorganic fine particles 2 coated with the silane monomer 3, the binder component 6 is likely to be charged, so that dust resistance and dust separation are increased. The decrease in sex becomes remarkable. Therefore, the range in which durability can be improved while maintaining antiallergenicity, dustproofness, and dust separation properties is the content of the inorganic fine particles 2 coated with the silane monomer 3 contained in the inorganic fine particle layers 10 and 20. On the other hand, the total content of the anti-allergen agent 5 and the binder component 6 is 40% by mass or less, and the content of the inorganic fine particles 2 coated with the silane monomer 3 contained in the inorganic fine particle layers 10 and 20 is Thus, the content of the binder component 6 is 0.1% by mass or more and 40% by mass or less, preferably 0.1% by mass or more and 30% by mass or less, more preferably 0.1% by mass or more and 20% by mass or less.

  Next, a method for chemically bonding the substrate 1 and a solution in which the inorganic fine particles 2 having a silane monomer bonded to the surface and the anti-allergen agent 5 are mixed will be described. In the present embodiment, as a method of chemically bonding, a bonding method by graft polymerization is used.

  Examples of the graft polymerization in the composite members 100 and 200 having anti-allergenicity and dust resistance of the present embodiment include graft polymerization using a peroxide catalyst, graft polymerization using heat and light energy, and graft polymerization using radiation (radiation grafting). Polymerization).

  Of these, radiation graft polymerization is particularly suitable from the viewpoints of simplicity of the polymerization process and production speed. Here, examples of the radiation used in the graft polymerization include α rays, β rays, γ rays, electron beams, ultraviolet rays, and the like. Lines and ultraviolet rays are particularly suitable.

  The method for producing the composite member 100 having antiallergenicity and dustproofness using graft polymerization in the present embodiment is suitably produced by the method described below.

  As a first preferred method in the present embodiment, the anti-allergen agent 5 is added to the solution in which the inorganic fine particles 2 chemically bonded with the silane monomer 3 are dispersed and mixed sufficiently, and then the substrate 1 to be bonded is bonded. After coating on the surface (resin surface) and removing the solvent by heat drying or the like as necessary, inorganic fine particles 2 in which silane monomer 3 is chemically bonded to γ rays, electron beams, or ultraviolet rays are formed. By irradiating the surface of the coated substrate 1, the silane monomer 3 is graft-polymerized on the surface of the substrate 1, and at the same time, the inorganic fine particles 2 are bonded, so-called simultaneous irradiation graft polymerization.

  In addition, as a second preferred method in the present embodiment, inorganic fine particles 2 in which the surface of the substrate 1 is irradiated with radiation such as γ rays, electron beams, or ultraviolet rays and then chemically bonded with the silane monomer 3 are used. It is produced by so-called pre-irradiation graft polymerization in which an anti-allergen agent 5 is added to the dispersed solution and a sufficiently mixed solution is applied to react the silane monomer 3 with the substrate 1 and simultaneously bind the inorganic fine particles 2.

  In the present embodiment, as described above, a solution in which the anti-allergen agent 5 is added and mixed sufficiently to the solution in which the inorganic fine particles 2 to be immobilized are dispersed is applied to the surface of the substrate 1 to be immobilized, and the composite member is formed. To manufacture.

  As a specific method for applying the dispersion liquid of the inorganic fine particles 2, generally used spin coating method, dip coating method, spray coating method, cast coating method, bar coating method, micro gravure coating method, Various methods such as screen printing, pad printing, offset printing, dry offset printing, flexographic printing, and inkjet printing can be used as gravure coating methods or partial coating methods. There is no particular limitation as long as it can be used and can be applied according to the purpose.

  Further, in order to perform graft polymerization of the silane monomer 3 efficiently and uniformly, the surface of the substrate 1 is previously subjected to corona discharge treatment, plasma discharge treatment, flame treatment, chromic acid, perchloric acid, or the like. Hydrophilic treatment may be performed by chemical treatment with an aqueous solution of an oxidizing acid or an alkaline aqueous solution containing sodium hydroxide.

  As described above, according to the composite member 100 having anti-allergenicity and dustproofness according to the embodiment of the present invention, at least the surface 1 is made of resin, and is fixed to the surface of the substrate 1, and the anti-allergen agent 5 An inorganic fine particle layer 10 including inorganic fine particles 2 coated with a silane monomer 3 having an unsaturated bond, and resists the content of the inorganic fine particles 2 covered with the silane monomer 3 in the inorganic fine particle layers 10 and 20. Since the allergen agent 5 content is 1% by mass or more and 20% by mass or less, it is difficult for particulate floating substances such as dust, sand dust, or pollen to adhere, and even if these particulate floating substances adhere. It can be easily removed and can inactivate allergens in particulate suspended matter.

  Further, the silane monomer 3 having an unsaturated bond having excellent reactivity with the surface of the substrate 1 is chemically bonded to the surface of the inorganic fine particle 2 by a dehydration condensation reaction to introduce an unsaturated bond. The inorganic fine particles 2 are fixed by reacting with the unsaturated bonds introduced on the surface of the resin or the resin surface of the substrate 1. In addition, by adding the binder component 6, the anti-allergen effect and the dust-proof effect excellent in durability for strongly bonding the inorganic fine particles 2 coated with the silane monomer 3 and between the inorganic fine particles 2 and the substrate 1 for a long time. It can be maintained.

  Further, according to the present embodiment, since the inorganic fine particles 2 can be firmly fixed on the substrate 1 by the chemical bond 4, it can be performed after the spinning into a product shape or in the process of commercialization. For this reason, there exists a merit that presence of the inorganic fine particle 2 which has various functions does not affect spinnability.

  Further, since the inorganic fine particles 2 can be formed in a single particle film shape or a multilayer particle film shape on a substrate made of a film, a resin plate, a fiber, a cloth, or the like, since the texture of these substrates is not impaired, It becomes possible to provide a composite member having dust resistance that can be applied.

  In the embodiment of the present invention, the substrate can be in various forms (shape, size, etc.) suitable for the purpose of use, such as film, fiber, cloth, mesh, and honeycomb. It is. Therefore, it is possible to add antiallergenic and dustproof functions to these various types of substrates, and to build agricultural materials such as house films and tunnel house films, exterior wall materials, sashes, doors and blinds. Interior materials such as clothing, wallpaper, carpets, resin tiles, clothing, innerwear, socks, gloves, shoes, footwear, pajamas, mats, sheets, pillows, pillowcases, blankets, towels, duvets and duvet covers It can be applied to products of textile structures such as filters, insect screens, meshes for screen printing, etc. for equipment, hats, handkerchiefs, towels, carpets, curtains, air cleaners and air conditioners, ventilation fans, vacuum cleaners, electric fans, etc. . Therefore, the present invention is a useful member that can provide various products excellent in various fields.

  Next, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to only these examples.

  In the following examples and comparative examples according to the method of the present invention, the fine particle immobilization body is produced by electron beam graft polymerization using an electro curtain type electron beam irradiation apparatus, CB250 / 15 / 180L, manufactured by Iwasaki Electric Co., Ltd. did.

(Preparation of silane monomer-coated fine particle liquid)

(Comparative Example 4)
Comparative Example 4 is the same as Comparative Example 4 except that a polymer compound having a phenolic hydroxyl group as an antiallergenic agent (made by Sekisui Chemical Co., Ltd., Allele Buster) in methanol is equivalent to Comparative Example 2 (equivalent to 30% by mass).

(Comparative Example 5)
As Comparative Example 5, evaluation was performed using an untreated mesh.

(Dustproof evaluation)
Dust resistance is measured by cutting each sample to a size of 10 x 10 cm, sprinkling the mixed dust mixed with Kanto Loam, silica sand, cotton linter and carbon black in accordance with JIS Z 8901, and measuring the weight. The weight of the mesh before and after dust adhesion was measured and evaluated.

  In addition, dust separation is evaluated by cutting each sample to a size of 10 x 10 cm, sprinkling the mixed dust compliant with JIS Z 8901 evenly, applying impact, and measuring the weight change of the sample before and after impact. did.

  The durability of the dustproof property was measured after the sample surface was washed 10 times back and forth using a commercially available sponge while applying a load of 100 g.

(Antiallergenicity evaluation)
For evaluation of antiallergenicity, each sample was cut to a size of 3 × 3 cm, further cut into pieces, and then immersed in 3 ml of a 10 μg / ml mite allergen protein solution. After 24 hours, the amount of mite allergen in the supernatant was determined. A mite checker (manufactured by Shinto Fine Co., Ltd.), a simple mite allergen test kit, was used to determine the amount of mite allergen.

  Table 2 shows the criteria for determining the mite allergen amount by the Mighty Checker. Determine the level of mite allergen concentration in the color development state of the test paper line. The determination with "-" and "+-" is judged to be effective because the allergen concentration is kept low by the anti-allergen agent. “+” And “++” were judged to have no effect by the anti-allergen agent.

  In addition, anti-allergen durability was evaluated after each sample was placed in boiling water for 30 minutes.

  From the results in Table 3, the following became clear. In other words, if the anti-allergen agent is 1% by mass or more and 20% by mass or less with respect to the silane monomer-coated inorganic fine particles, it is possible to form a composite member having excellent anti-allergen properties, dust resistance, and dust separation properties (implementation) Examples 1-6).

  In contrast, when the amount of the anti-allergen agent is as small as 0.5% by mass, the inorganic fine particle layer is excellent in dustproofing and dust-removing properties, but the antiallergenic effect is weak (Comparative Example 1). It was confirmed that both the dustproof property and the antiallergenic property were reduced when the amount was increased to 30% by mass (Comparative Example 2).

  Moreover, although the anti-allergen property was shown in the mesh processed only with the anti-allergen agent, the dustproof property was inferior to the untreated mesh (Comparative Examples 3 and 4). This is thought to be because the anti-allergen agent has light tackiness even after drying.

  The antiallergenicity is not proportional to the amount of the antiallergen, and is 3 to 15% by mass (Examples 2 to 5 and 7 to 11), particularly 5 to 10% by mass (Examples 3, 4, 7, 8, and 11). It showed a strong effect. This is because the silane monomer on the inorganic fine particle and the hydrophobic part of the anti-allergen agent are bonded by hydrophobic interaction, and at a low concentration, it is efficiently dispersed together with the inorganic fine particle, but at a high concentration, a hydrophobic bond occurs between the anti-allergen agents. Therefore, it is presumed that the efficiency has decreased. Alternatively, since it is an inorganic fine particle film, the surface area is increased and an excellent effect is exhibited even at a low concentration, but it is also considered that when the anti-allergen agent is added excessively, the area between the inorganic particles is filled and the working area is reduced.

  Furthermore, the addition of the binder component increased the strength of the inorganic fine particle layer and improved the durability against dust (Examples 7 to 9 and 11).

  However, when the amount of binder component added is increased, the dust resistance and dust separation properties begin to deteriorate. When the total amount of the anti-allergen agent and the binder component is 40% by mass, a decrease in the dust resistance and anti-allergen property is also observed. (Example 10).

  Further, even when a compound having water repellency and oil repellency was used as the binder component, it exhibited dust resistance, durability and antiallergenicity equivalent to those of the conventional binder component. Thereby, the possibility of exhibiting antifouling properties and antiallergenic properties against liquid dirt and allergens contained therein was found (Example 11).

  In the examination of anti-allergenic durability by boiling test, the anti-allergen agent applied directly to the mesh can maintain the durability when applied at a high concentration (Comparative Example 4), but 10% by mass With considerable application, the antiallergenic durability decreases (Comparative Example 3). When the same amount of anti-allergen agent as in Comparative Example 3 is used in combination with inorganic fine particles coated with a silane monomer, it is observed that anti-allergenicity is sustained (Example 4).

  Furthermore, in the embodiments of the technology according to the present invention, the substrate is formed in various forms (shape, size, etc.) suitable for the purpose of use, for example, film shape, fiber shape, cloth shape, mesh shape, honeycomb shape, and the like. Therefore, the present invention can be applied to products obtained by adding a dustproof function to various types of substrates.
