Abstract

The invention discloses a manufacturing process of glass fiber reinforced plastic. The manufacturing process comprises the following steps of preparing colloid,: preparing the colloid according to the proportion of 98 percent of gel coat and 2 percent of curing agent under the environment of temperature of 25 DEG C and humidity of 70 percent and uniformly stirring; coating the colloid: uniformly coating the colloid prepared in the step a on a mould, wherein the using amount is 300-500 grams / square meter and the brushing thickness is 0.3-0.45 mm; gelling: gelling under a normal temperature environment for 30-40 minutes; laying glass fiber: laying a glass fiber layer; rolling resin: uniformly coating the resin on the glass fiber layer, wherein the thickness of the coating is 3.5-4.5 mm; and curing, forming and demolding under the condition of normal temperature. By using the method provided by the invention, the reject ratio of products can be effectively reduced, and the product quality can be improved and guaranteed.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a manufacturing process of glass fiber reinforced plastics. Background technique [0002] FRP is a type of composite material. Due to its unique performance advantages, FRP materials have been widely used in more than ten industries related to aerospace, railways, decorative buildings, home furniture, advertising displays, craft gifts, building materials and bathrooms, yacht mooring, sports materials, sanitation engineering, etc. Applied, and highly praised, it has become the darling of the needs of merchants in the new era in the material industry. FRP products are also different from traditional material products. They are much better than traditional products in terms of performance, use, and lifespan. They are easy to shape, customizable, and can be freely adjusted in color. They are favored by merchants and sellers and occupy more and more Big marke...
