Embodiment Construction
[0012] The present invention adopts a glass fiber reinforced plastic mold, and the mold is made of several pieces. A special heating element is installed in the mold to make the temperature of the mold reach 68°C, and then a transparent resin gel coat is applied on the inner surface of the mold to form a semi-solid. The prepared wood grain coating (color material, resin, curing agent, accelerator) is brushed on the gel coat to make the wood grain coating form a semi-cured state, and the auxiliary layer is carried out according to the size of the product (the auxiliary layer materials are: polyester resin, glass fiber, filling powder, flame retardant, flame retardant powder, anti-aging agent) to form a product.

The invention provides a one-off press forming process for integrally forming simulated wood grain patterns through die pressing. The process comprises: adopting an FRP (glass fiber reinforced plastics)-body die formed by piecing a plurality of block; installing a specially-made heating element in the die; allowing the temperature of the die to reach 68 DEG C; coating the the surface of an inner layer of the die with a transparent resin glue coat and forming a semi-solidified state; brushing wood grain paint (pigment, resin, curing agents and accelerators) prepared in advance on the glue coatand allowing the wood grain paint to be in a semi-solidified state at the same time; and forming auxiliary layers according to product size (auxiliary-layer materials are polyester resin, glass fiber,filling powder, flame retardant, flame-retardant powder and anti-aging agents) so as to form products.
Description
Technical field: [0001] The invention relates to the technical field of producing glass fiber reinforced plastic doors with molds, in particular to a process of spinning real wood grain patterns formed by pressing molds into one piece. Background technique: [0002] At present, there are basically two kinds of art decoration patterns of building decoration materials on the market. One is to use paint to finish the surface to obtain artistic patterns; These two methods mainly have the characteristics of short service life, fast aging, especially too many harmful chemical components in the paint, which do not meet the national environmental protection standards, high production costs, and poor product quality. Invention content: [0003] The present invention provides a spinning real wood grain pattern process which is integrally formed by one-time pressing forming mold. [0004] The present invention is realized in this way: the technological process adopted by the spinnin...
