Manufacturing process for glass fiber-reinforced plastic product

Abstract

The invention discloses a manufacturing process for a glass fiber reinforced plastic product. The manufacturing process comprises the following steps: S1, material selection: selecting an appropriateamount of unsaturated resin, glass fibers and a gel coat; S2, mold preparation: cleaning the mold, wiping the mold with soft gauze to thoroughly eliminate impurities on the surface of the mold, and then carrying out drying to remove water stains; S3, coating of a release agent: uniformly coating the interior of the mold with the release agent, wherein it is ensured that every corner is coated, polyvinyl alcohol has to be thoroughly dried, and two-hour standing is needed for polishing wax, non-silicone oil paste and other release agents so as to allow solvents to volatilize; and S4, coating ofgel coat resin, wherein a hairbrush may be used for brushing, and the gel coat is cured to the extent that the gel coat feels slightly sticky in contact but does not stain the fingers. Compared with other production processes, the manufacturing process of the invention is low in price, reduced in needed space and mature in technology; and the prepared glass fiber-reinforced plastic product has good processability and good comprehensive performance after curing, is more and more widely applied to construction, corrosion prevention, shipbuilding, transportation, the automobile industry, the electric appliance industry, etc., and is greatly improved in quality.

Description

technical field [0001] The invention relates to the field of glass product manufacturing, and more specifically, relates to a manufacturing process of glass fiber reinforced plastic products. Background technique [0002] FRP (also known as glass fiber reinforced plastic, the internationally recognized abbreviation is GFRP or FRP) is a composite material with a wide variety of properties and a wide range of uses. It is a new functional material made of synthetic resin and glass fiber through a composite process. FRP material has light weight, high specific strength, corrosion resistance, good electrical insulation performance, slow heat transfer, and thermal insulation. Good, good instantaneous ultra-high temperature resistance, easy coloring, and the ability to pass through electromagnetic waves. FRP products are disposable when they are made and molded, which is another remarkable feature that is different from metal materials. As long as the appropriate raw material layi...

Problems solved by technology

[0003] However, the production process of traditional FRP products is relatively complicated, and it is very inconvenient to operate, and the edges of the formed FRP products are very rough, the edges and corners are not clear, the appearance is not beautiful, and it does not have good flame retardancy. , will directly lead to damage, which not only affects the overall aesthetics, but also reduces the service life of FRP products. Therefore, we propose a manufacturing process for FRP products
