Abstract

A composition is disclosed which can hydrophilify the surface of a member to impart an antifogging property to the surface of the member. The composition for hydrophilifying the surface of the member comprises at least (a) photocatalytic particles of a metallic oxide, (b) a precursor capable of forming a silicone resin film or a precursor capable of forming a silica film, and (c) a solvent, the total content of the photocatalytic particle and the solid matter of the precursor in the composition being 0.01 to 5% by weight. The hydrophilic property can be imparted simply by applying the composition onto a member and drying or heating the composition applied to the member. The resultant hydrophilic thin film is transparent and, hence, does not sacrifice the transparency and appearance of a member required to be transparent. Further, the surface of a member with the above composition applied thereto has such a property that water droplets adhered thereon can be immediately removed by vaporization and the surface is less likely to be soiled and, even when a contaminant is adhered thereon, can easily release the contaminant therefrom.

More specifically, the present invention relates to a composition which highly hydrophilizes the mirror surface 'glass, lenses' and other elements to prevent the surface of the object or element from fogging, forming water droplets, or cleaning The surface of the component, or evaporation, accelerates the removal of water droplets on the surface of the component, so that the object or the surface of the component dries quickly. TECHNICAL BACKGROUND When windshields or window glass of automobiles and other vehicles, window glass of buildings, spectacle lenses, and cover glass of various instrument panels are exposed to cold weather, they often fog due to condensation of moisture. In addition, mirrors and spectacle lenses in bathrooms or washrooms are often blurred by water vapor. Object surface Exposure to a temperature below the dew point of the atmosphere will cause moisture in the atmosphere to condense on the surface of the object, forming water droplets, and generating mist. When the condensed water droplets are small and have a diameter of about half the wavelength of visible light, the water droplets scatter light, making glass and mirrors opaque, and as a result lose their visibility. The re-condensation of moisture combines the condensed small water droplets into larger separated water droplets, causing the light at the interface between the water droplet and the surface of the object and the interface between the water droplet and the air to refract the light. Fog situation. Therefore, for transparent objects such as glass, the perspective image will be distorted, reducing its perspective, and the mirror's reflection image will be disturbed.

Invention Description (2 ~~; In addition, when the vehicle windshield or window glass, building window glass, Vehicle rearview mirrors, spectacle lenses, and masks or helmet shields are exposed to rain or sprayed with water, and a large amount of water droplets adhere to the surface, which makes the surface of the object cloudy, fuzzy, and spots or other fogging conditions. Visibility is lost again. Needless to say, "fogging or clouding" will greatly affect the safety and efficiency of various tasks. For example, in cold or rainy days, the vehicle windshield or window glass and the vehicle rearview mirror Fogging or clouding makes poor visibility and obstructs vehicle traffic safety. Fogging of endoscopes, dental mirrors, and condensers of laser dental instruments can prevent proper diagnosis, surgery, and treatment. Cover of instrument panel The fog of the film will make it difficult to read the data. In addition, in terms of buildings and coatings, environmental pollution problems also plague the building's 'to the exterior materials of the building' and its coating. When the weather is good, the floating Dust and particles swimming in the air are deposited on the roof and external walls of the building.

However, in recent years, it has been recognized that the coating surface is as hydrophilic as possible. It is more effective for large amounts of hydrophobic urban dust (Kobunshi, Vol. 44, May 1995, p. 307). Therefore, there have been reports of applications of hydrophilic graft polymers in building coatings (`` Japan Chemical Week ", January 30, 1995). According to this report, the coating has a hydrophilicity of 30 to 40 on the contact angle with water. . Generally, the soil inorganic dust has a contact angle of 20 with water. To 50. Therefore, the contact angle with water is 30. To 40. The graft polymer has an affinity and is likely to adhere to its surface. Therefore, the grafted polymer coating cannot completely prevent the sludge of inorganic dust.

Printed by the Consumer Cooperative of the Central Bureau of Procurement, Ministry of Economic Affairs. To hydrophilize the components of the coating composition, the surface is illuminated with light. The phenomenon of hydrophilization is considered to proceed through the following reaction mechanism. However, this reaction mechanism is only hypothetical and does not limit the fe range of the present invention. When light is given, its energy is still the energy difference between the upper limit of the valence band of the photocatalyst and the lower limit of the conduction electron band. Either or both of them are used to provide the polarity of the photocatalyst surface (probably electron-drawing properties). This allows more water to be chemically adsorbed on the surface than the atmospheric equilibrium water. Then, the surface free energy 'induced by hydrogen bonding is increased to generate physical adsorption, so that the number of water molecules attached to the surface is increased due to the increase of the surface free energy. In general, when the surface free energy of one substance is close to the surface free energy of another substance, these substances may adhere to each other. Therefore, water molecules are physically adsorbed on the surface and have good water wettability, that is, the surface is hydrophilized. In addition, the degree of hydrophilization of the surface provided by the composition of the present invention does not depend on the thickness of the film of the composition. It is known that a photocatalyst is oxidizing, and a film containing a photocatalyst has antifouling, antibacterial, and deodorizing effects due to this activity. The present inventors have confirmed that the amphipathic nature of this oxidative decomposition depends on the thickness of the photocatalyst-containing film. In addition, the present inventors have confirmed that the thickness of the film of the composition of the present invention induced hydrophilization is sufficient to make the oxidative decomposition activity very low or even absent. Furthermore, the inventor ^ confirmed that the thickness of the film provided by the composition of the present invention can be as small as not to affect the transparency of the transparent element, and the chemical decomposition activity is very limited, or 7 papers are suitable for the countries of the financial country (CNS) A4 specification (21 () χ29 ») 467943 Α7 '_ Β7 V. Description of invention (.7) In some cases, there is no such thing at all. When the surface is hydrophilized, the hydrophilicity can be maintained for a week even when placed in a dark place. In order to make the surface highly hydrophilized by the photocatalytic effect of the photocatalyst, the irradiation intensity of the excitation light is preferably not less than 0.001 mff / cm2, and more preferably not less than 0.01 mff / cm2, and the best It is not less than 01 raW / cm2. When the photocatalytic oxide is anatase titanium oxide, rutile titanium oxide, zinc oxide, or strontium titanate, daylight, indoor lamp, fluorescent lamp, mercury lamp, incandescent lamp, xenon lamp, high-pressure sodium lamp, metal halide lamp, BLB lamps and the like can be used as light sources for photocatalytic photoexcitation. In addition, when the photocatalytic oxide is tin oxide, a sterilization lamp, a BLB lamp, etc. can be suitably used as the light source. The thickness of the surface layer formed on the surface of the element by using the composition of the present invention is preferably not more than 0.4 μm. When it does not exceed 0.04 μm, turbidity caused by irregular reflection can be avoided, so the surface layer is substantially transparent. In order to effectively avoid the occurrence of surface color caused by light interference, its surface thickness is more preferably not more than 0.2 μπ}. The smaller the thickness of the surface layer, the better the transparency of the surface layer, and the better the resistance to damage.

In the structure shown in Fig. 3, there is an inner container (13) in the container of Fig. 1, which is filled with a coating liquid sample D11 and a propellant gas such as nitrogen: DEM 'or LPG. This structure has the advantage that even if the resin liner has a small hole, the composition of the present invention does not enter and directly contacts the metal container frame ⑴. …, In the structure shown in Figure 4, in the container shown in Figure 丄, there is a balloon container (14), which has pressure resistance and good pressure transmission, and there is a hole in the bottom of the container. This configuration allows gas and liquid to be filled into the relevant parts of the container separately. For example, the balloon-like container (14) (illustrated in the figure) is filled with the composition of the present invention, and the space between the outer container and the balloon-like container (part in Figure B) is filled with nitrogen.

Description of Invention (.26 ) The light shines for an hour. Then, the anti-fogging property of the coating was evaluated. The evaluation criteria are as follows. :: The layer-coated glass was blown, and as a result, it was not fogged. 〇: The layer-coated glass is blown, and the result is slightly fogged, but the image can be clearly seen through the layer-coated glass. A: Blowing on the layer-coated glass results in fogging, but the image cannot be clearly seen through the layer-coated glass, although the fogging is not serious compared to the matrix glass itself. X: The layer-coated glass is blown. As a result, compared with the producer of the matrix glass, there is a fogging phenomenon. As for the anti-fogging property, samples A1 and A2 were rated as ◎, and sample A3 was X. The adhesion of the coating of the sample A1 to the substrate and the peelability of the coating from the substrate were evaluated. In this case, in order to evaluate the adhesion of the coating to the substrate, a immersed Kimwipe slipped over the coating and the number of times it was necessary to peel off the coating from the substrate was measured. The adhesion of the coating to the substrate was evaluated by the number of slips. In addition, in order to evaluate the peelability of the coating from the substrate, a plastic wiper was used to slide over the coating, and the number of slips required to peel the coating from the substrate was measured. The coating was evaluated by the peelability of the substrate by the number of slips. Each test was repeated three times. As a result, in terms of the adhesion of the coating to the substrate, the sliding motion was repeated 20 times without peeling. In addition, the coating is peeled from the substrate by the sliding action of the substrate 2 to 3 times.

The result of good dispersibility shows that the addition of copper as the antibacterial metal to the coating liquid does not affect the operation of the coating liquid, so the coating liquid can be applied as in Example 1. Example A3 Silica was added. Titanium oxide sol (TA-15) was diluted with ethanol to prepare a coating liquid, in which the concentration of oxidized particles was 0.5% by weight. In addition, titanium oxide sol (TA-15) was mixed with silica sol (" Glasca A, " average particle diameter is 10 nm 'made by Japan Synthet ic Rubber Co., Ltd.), and the mixture was diluted with ethanol to prepare 5% 重量 比。 The coating liquid, wherein the concentration of titanium oxide particles is 0.5% by weight, and the concentration of silica particles is 0.5% by weight. Each coating liquid layer was applied to a 10 cm 2 soda-lime glass substrate. The coating substrate was placed at 50 ° C. for one hour, and then allowed to stand for 15 minutes to cool the coating substrate to obtain samples A4 and A5. Inspect samples A4 and A5 for coating. As a result, the sample A4, the coating highly reflects visible light and has a flash, while the sample A5, the coating substantially does not reflect visible light and has good visible light permeability. In addition, the samples A4 and A5 were irradiated with light from a light source (BLB fluorescent lamp) having an intensity of 0.25 mW / cm2 for 2 hours. Assess coating anti-fog properties. As a result, both samples had good anti-fogging properties in the evaluation method of anti-fogging properties as in Example A1 (©). The above results show that the addition of silica with a refractive index lower than that can make the coating have excellent anti-fogging properties while retaining the visible light transmittance of the surface.

Description of the invention (30) As shown in Figure 7, no matter how long the ultraviolet light is irradiated The matrix glass basically only exhibits anti-fogging grade X. However, after 50 hours of UV light irradiation, the samples of all coating liquid samples B1 to B4 have good anti-fogging properties on the surface of the matrix glass (◎ ). The coating liquid samples B1 did not exhibit anti-fogging properties before UV light irradiation, and the coating liquid samples B2 to B4 showed anti-fogging properties before and after UV light irradiation. Coating liquid sample B1 The reason that the coating sample does not have initial anti-fogging property is considered to be that ethanol remains in the coating. Increasing the irradiation time to obtain anti-fogging 'may be due to the photo-excited reaction of the photocatalyst to decompose ethanol. In contrast, the samples prepared from the coating liquid samples B2 to B4 doped with a surfactant have antifogging properties due to the presence of the surfactant plus ethanol. After a short time, it loses its anti-fog property and then recovers. The reason is as follows. The photo-excited reaction of the photocatalyst not only decomposes ethanol, but also decomposes the surfactant 'to obtain an intermediate product. During the decomposition process, the hydrophilicity is lost' and the antifog property is temporarily lost. However, after the surfactant is completely decomposed ', it returns to its hydrophilicity, and the antifogging property is restored. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs This result proves that the addition of surfactants in addition to photocatalytic titanium oxide particles, silica, and ethanol will not only obtain permanent antifog, but also get initial antifog . The larger the amount of surfactant, the longer it will temporarily lose the anti-fog property. In particular, the coating liquid sample B2 coating sample has a surfactant addition amount as small as 0.4 parts by weight, compared to one part by weight photocatalytic titanium oxide particles, the time lost is about 2 hours, and the coating Liquid sample B3 coating The paper size is in accordance with Chinese National Standard (CNS) A4 specification (21〇χ 297 mm) ~ "^ 67943 A7 B7 V. Sample of invention description (31), the surfactant addition amount is 1 Part by weight ratio, compared to one part by weight photocatalytic oxidation of Chin particles, the time lost is about 5 hours, while the coating liquid sample B4 coating sample, the surfactant addition amount is 2 parts by weight, compared to At a weight ratio of photocatalytic titanium oxide particles, the loss time is about 24 hours. In addition, the sample of the coating liquid coating had the surfactant added at a reset ratio of 10 parts, and the lost time was about 200 hours or more compared to one part by weight of the photocatalytic titanium oxide particles. When the coating liquid is an aerosol formulation, the time for which the antifogging property is temporarily lost is preferably 1 day or less. The added amount of the surfactant is preferably less than 10 parts by weight, and more preferably More than 2 parts by weight. In addition, the substrate glass and coating liquid samples B1 to B4 irradiated with BLB light for 50 hours were measured on the glass surface, and the contact angle between the sample surface and water was measured. Using a contact angle angle goniometer (CA_X150, manufactured by Kyowa Interface Science Co., Ltd.), a piece of water was dripped onto the sample surface with a microsyringe, and the contact angle of the sample surface with water was measured after 30 seconds. Printed by the Consumers' Cooperative of the Central Government Bureau of the Ministry of Economic Affairs, the contact angle of the matrix glass was 30. 'And all coating liquid samples B1 to B4 coated substrate glass samples have good contact angle of blood and water, that is, the contact angle is about the same, coating liquid samples B1 to B4 coating prepared Samples on the surface of the matrix glass. These samples have been tested for contact angle with water to evaluate the possibility of removing oil. Specifically, the surface of each sample was coated with an oleic acid layer, and then each sample was immersed in water in a water tank, so that the surface of the sample was placed horizontally. As a result, oleic acid becomes spherical, and light rubbing causes oil droplets to be released from the surface of the sample. . This paper applies the national standard (CNS) A4 standard of towels.
