摘要： PROBLEM TO BE SOLVED: To obtain a sealing material for building that can reduce the exudation of a plasticizer and a fat or oil component that are included in a polymer sealing material and increase the staining on external finishing materials. SOLUTION: In a sealing material including organic substances 1, for example, a plasticizer, a fat or oil component, particularly a silicone oil-containing silicone sealing material, fine particles of a photocatalyst 3 area allowed to distribute in the material to decompose or degenerate the organic substances, the included plasticizer, fat and oil components, and the like, by the action of the photocatalyst, thereby reducing the staining of buildings due to adhesion of these organic substances to the buildings. The photocatalyst fine particles may be dispersed in the sealing material or may distribute on the surface of the sealing material. Further, a layer including the photocatalyst fine particles may be formed on the sealing material, when necessary, via a layer that inhibits the action of the photocatalyst.

摘要： PROBLEM TO BE SOLVED: To provide production by which a photocatalyst layer that shows good covering power and excellent adhesion even to an aluminum alloy base material having a complicated shape, can be formed without reducing strength of the aluminum alloy base material. SOLUTION: This production comprises: subjecting a base material 11 that consists of an aluminum alloy, to anodic oxidation treatment to form an anodic oxide coating film 12 on the base material 11; further immersing the treated material in a solution contg. suspended fine semiconductor particles 10, coating the treated material with the solution contg. suspended fine semiconductor particles 10 (liquid suspension of fine semiconductor particles 10) or subjecting the treated base material to electrophoresis treatment in the liquid suspension of fine semiconductor particles 10, to deposit the fine semiconductor particles 10 on the anodic oxide coating film 12; and thereafter, subjecting the resulting material to sealing treatment to form a photocatalyst layer consisting of a composite phase in which a swelled anodic oxide coating film 12a and the fine semiconductor particles 10 coexist, and also to improve corrosion resistance of the aluminum alloy base material 11. At this time, since the production is a wet process, the photocatalyst layer that shows good covering power even to the base material having a complicated shape, can be formed even at room temp. Thus, the formation of the photocatalyst layer also having sufficient massproductivity can be performed without any possibility of reducing strength of the aluminum alloy base material 11.

摘要： PROBLEM TO BE SOLVED: To preserve a constructive material with fungicidal property by mixing semiconductor particles, which shows a feeble photocatalyst action, in a base material composed of polymeric materials specifying the particle size and mixture ratio. SOLUTION: A fungicidally constructive watertight and airtight material 10, such as a gasket for fixing glass to a window, has semiconductor particles 2 showing a feeble degree of photocatalyst action that may not cause any damage to a base material mixed in the base material composed of polymeric materials 1 and is formed by depositing an antibacterial metal or an antibacterial metal compound 3 on the base material surface. The particles 2, whose diameter is 0.01 to 10μm, or preferably 0.1 to 1μm, are mixed on the base material in an amount of 0.5 to 100weight%, or preferably 1 to 20weight% with respect to the base material so that at least a part of the particles 2 may be show up above the base material surface. The antibacterial metal or the antibacterial metal compound 3 is then separately stuck on the particles 2 appearing on the base material. Thus not only can excellent antibacterial and fungicidal properties be displayed for a long period but also manufacturing can be facilely accomplished at low cost and deterioration of a mechanical property of the polymeric materials can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a photocatalyst film structure capable of forming a matte photocatalyst film low in glossiness without lowering the original action such as antistaining action, antibacterial action, antifungal action, deodorizing action or air cleaning action and durability of the photocatalyst film and capable of controlling finish glossiness. SOLUTION: An intermediate layer 2 is interposed between a base material 1 and a photocatalyst layer 3 and a filler comprising inorganic fine particles 4, for example, metal fine particles or oxide fine particles having a refractive index different from that of the matrix itself of the intermediate layer is added to the intermediate layer 2 and the difference between the refractive index of the filler and that of the intermediate layer is utilized or the surface of the intermediate layer or the internal surface (cross-sectional face of the intermediate layer) is made uneven to make it possible to scatter incident light to lower glossiness. By controlling the addition amount or mean particle size of the filler, glossiness can be controlled arbitrarily and freely. As the inorganic fine particles, metal fine particles, oxide fine particles or mixed fine particles of them can be used but SiO2 fine particles are especially preferable.

摘要： PROBLEM TO BE SOLVED: To form a photocatalyst film which has a good throwing power even to an aluminum alloy base material having intricate shapes without degrading the strength of the base material and has an excellent adhesion property and photocatalyst activity. SOLUTION: After the base material 11 consisting of an aluminum alloy is subjected to an anodic oxidation treatment, the base material is immersed into a soln. suspended with semiconductor particulates 10 having the photocatalyst effect or the suspension of the semiconductor particulates 10 is applied thereon or an electrophoresis method is executed in the suspension of the semiconductor particulates, by which the semiconductor particulates are deposited on the anodically oxidized film 12. The film is thereafter impregnated with an inorg. high polymer 13, by which the photocatalyst film 14 consisting of the mixture composed of the semiconductor particulates and the inorg. high polymer is formed on the anodically oxidized film. This process is a process of a wet type and, therefore, the throwing power to the aluminum alloy base material 11 having the intricate shapes is good. In addition, the formation of the photocatalyst film at a low temp. is possible and, therefore, there is no possibility of degrading the strength of the aluminum alloy base material. The method for forming the photocatalyst film having the high mass productivity is thus obtd. The photocatalyst film has a high content of the semiconductor particulates and exhibits the excellent photocatalyst activity.

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a functional member, capable of forming a functional film such as a photocatalytic film having superb adhesive properties on an organic coating film while the outer appearance and design of the organic coating film are preserved, without impairing the original function of the functional film. SOLUTION: In the manufacture of the functional member consisting of a functional film formed on the surface of the organic coating film, especially in a photocatalytic functional member comprising a photocatalytic layer formed through an intermediate layer 3 made up of a material which is not eroded by a photocatalytic function, a film 2 of a heat-curable resin coating material is formed on a base 1 and a heat-curable resin coating film is preheated in such a manner that the coating film is insufficiently cured without changing its outer appearance. In addition, a layer containing a functional material is formed or a functional material layer 4 is formed after the intermediate layer 3 is formed, and then the layer is finally baked. For the preheating treatment of the heat-curable resin coating film, it is performed at a lower temperature than the final baking temperature of the coating film, preferably at a low temperature such as 10-60 deg.C. Further, the preferable resin coating film is the one of an acrylic resin or an acrylic melamine coated by electrodeposition.
