MOLDING METHOD FOR SYNTHETIC RESIN LAMINATE STRUCTURE

PURPOSE:To impart an excellent pattern and enhance the durability by spraying a colored resin liquid in the form of spots after gelation of a gelcoat layer formed on a mold surface, to thereby provide a colored spot layer, and providing a different-colored layer and a reinforcement layer. CONSTITUTION:A mold release agent is applied to the surface of a male mold 7, and a resin liquid consisting mainly of a transparent unsaturated polyester resin is applied thereto by a spray-up method to form a gelcoat layer 1, which is then gelled. Next, a uniform dispersion of a gold powder or the like in a transparent unsaturated polyester resin is sprayed to form a colored spot layer 2. On the outside of the colored spot layer 2, an admixture of a transparent unsaturated polyester resin with a pigment or the like is applied uniformly by a spray-up method to form a colored layer 3. A back reinforcement layer 5 comprising an ortho unsaturated polyester resin, which is loaded heavily with a white pigment, and glass fibers is formed on a female mold 6. The male mold 7 and female mold 6 are mated, and a mixture of an iso unsaturated polyester resin with colored pieces or the like is poured into the resulting mold, and is hardened to form a molding compound layer 4.
