で、幅広い需要が見込まれている。2. Description of the Related Art In recent years, composite molded articles made of synthetic resin have been developed in which a photocatalytic layer is laminated on a surface of a synthetic resin substrate via an inorganic protective adhesive layer. When this composite molded article is exposed to light, the attached dust and the like are decomposed by the photocatalytic action of the photocatalyst layer containing titanium oxide as a main component, the hydrophilic titanium oxide is exposed, and the composite article is washed with water or natural rainwater. It is a convenient one that has an antifouling function to remove dirt relatively easily, and is also known to have an antibacterial, antifungal and deodorant action. Therefore, a wide range of demand is expected, from architectural materials such as carport shingles and road materials such as highway soundproofing plates to industrial materials such as electronic equipment housings.

体に接着している。In such a composite molded article, it is necessary to adhere the photocatalyst layer to the synthetic resin base so as not to peel off, and the synthetic resin base is deteriorated due to the bad influence of titanium oxide contained in the photocatalyst layer. Therefore, a silicon-based protective adhesive layer having both adhesiveness and a protective function is laminated on the surface of the synthetic resin substrate, and the photocatalyst layer is formed on the synthetic resin substrate via the protective adhesive layer. Glued.

向上させることは困難であった。However, when the photocatalyst layer is bonded to the synthetic resin substrate via the silicon-based protective adhesive layer as in the above-mentioned composite molded article, the silicon-based protective adhesive layer has an adhesive property to the photocatalytic layer. Although good, the difference in thermal expansion and contraction between the photocatalyst layer and the protective adhesive layer and the synthetic resin substrate due to temperature change decreases the adhesion of the protective adhesive layer to the synthetic resin substrate, and the photocatalytic layer and the protective adhesive layer are combined with the synthetic resin substrate. However, it is difficult to improve the adhesion without lowering the protection function of the protective adhesive layer in order to solve this problem.

た。[0005] In addition, the above-mentioned composite molded article also has a problem that the photocatalytic layer is easily peeled from the synthetic resin substrate due to insufficient adhesion during bending, so that the bending processability is not good, and the durability and durability are poor. The weather resistance was hardly sufficient.

という問題があった。Further, the above-mentioned composite molded article is manufactured by forming a protective adhesive layer on the surface of a synthetic resin substrate and forming a photocatalyst layer thereon, and heating the protective adhesive layer and the photocatalytic layer under heating. Since there is no step of bringing the synthetic resin substrate into close contact with the resin under pressure, there is a problem that the adhesiveness is insufficient from this point and the resin is easily peeled off.

汚れを落とすことができる。This transfer film is superposed on the surface of the synthetic resin substrate such that the organic adhesive layer is on the synthetic resin substrate side, and the organic adhesive layer, the inorganic protective layer and the photocatalytic layer are synthesized by heating and pressing. It is transferred to the surface of the resin substrate to produce a synthetic resin composite molded body. The composite molded article thus manufactured is an inorganic protective layer having a protective function, in which a protective adhesive layer having both a protective function and an adhesive property is not formed between the synthetic resin substrate and the photocatalytic layer as in the conventional product. Since the organic adhesive layer having good adhesiveness is formed in two layers between the synthetic resin substrate and the photocatalyst layer, the synthetic resin substrate is reliably protected by the inorganic protective layer, The inorganic protective layer is in close contact with the photocatalyst layer, and is strongly adhered to the synthetic resin substrate by the organic adhesive layer. In particular, in this composite molded article, the organic adhesive layer is strongly pressed to the surface of the synthetic resin substrate by heating and pressing at the time of transfer, so that the adhesive strength is greatly improved. Then, the organic adhesive layer absorbs the thermal expansion / contraction difference due to the temperature change between the inorganic protective layer and the organic adhesive layer, and as a result, the thermal expansion / contraction difference between the respective layers can be substantially eliminated, It becomes difficult for the photocatalyst layer to peel off from the synthetic resin substrate.
In addition, the composite molded body is almost never peeled of the photocatalyst layer at the time of bending, and is hardly deteriorated in combination with the fact that the synthetic resin substrate is protected by the inorganic protective layer. It is durable, and can decompose dust and the like attached by the action of the photocatalyst layer and relatively easily remove dirt by washing with water or the like.

The inorganic protective layer is a silicon-based layer, and the organic adhesive layer is a urethane-based, acrylic, polyvinyl alcohol-based, or vinyl acetate-based adhesive. A layer of the agent.

Since it is firmly adhered to the synthetic resin substrate by the organic adhesive layer capable of absorbing the difference in thermal expansion and contraction, the peel resistance of the photocatalyst layer is greatly improved. In addition, since the silicon protective layer exhibits an excellent protective function, the synthetic resin substrate hardly deteriorates due to the adverse effects of TiO 2 and the like contained in the photocatalyst layer.
Since iO 2 and other metal oxides have a strong photocatalytic action, they can promote the decomposition of dust and the like.

きる。That is, in this composite molded article, since the silicon-based protective layer 3 exhibits an excellent protective function, the synthetic resin substrate 5
Is hardly degraded by adverse effects of metal oxides such as TiO 2 contained in the photocatalyst layer 2 and has excellent durability. The silicon-based protective layer 3 has a high adhesion to the photocatalyst layer 2 and a good adhesion to an organic adhesive layer 4 such as a urethane-based one. 5 and the organic adhesive layer 4 can absorb the difference in thermal expansion and contraction caused by the temperature change between the inorganic protective layer 3 and the organic adhesive layer 4. As a result, a substantial difference in expansion and contraction can be eliminated, so that the peeling resistance is greatly improved, and the peeling of the photocatalyst layer 2 becomes almost equal. In particular, since the organic adhesive layer 4 is strongly adhered to the synthetic resin substrate 5 by the heating and pressurizing at the time of transfer, the composite molded article has high peeling resistance. Therefore, this composite molded body is
Since peeling hardly occurs during bending, bending workability and the like are also good. When the composite molded body is exposed to light, the decomposition of attached dust and the like is promoted by the photocatalytic action of a metal oxide such as TiO 2 contained in the photocatalyst layer 2, and the composite molded body is made of hydrophilic TiO 2 or the like. Because the metal oxide is exposed,
Dirt can be removed relatively easily by washing or rainfall.

In addition, it is a matter of course that a composite molded body in which the organic adhesive layer 4, the inorganic protective layer 3, and the photocatalyst layer 2 are laminated on both surfaces by performing transfer to both surfaces of the synthetic resin substrate 5 may be manufactured. is there.
