Glass fiber reinforced plastic material manufacturing process

Abstract

The invention discloses a production and manufacturing process of a glass fiber reinforced plastic material in the technical field of production of glass fiber reinforced plastic materials. The method comprises the following specific steps: 1, mixing raw materials in proportion, and performing heating and stirring to a molten state; 2, pulling out the molten glass to produce glass fiber cloth; 3, shredding the glass fiber cloth by using a shredding device, and cooling the shredded glass fiber cloth; 4, finally, winding the glass fiber filaments. When glass fiber cloth is shredded, the arc-shaped partition plate is used for isolating cut glass fiber filaments in time, the cut glass fiber filaments are prevented from making contact again, then the vibration partition plate is used for vibrating, the fan blades are matched to rapidly cool and form the glass fiber filaments, and the phenomenon that the glass fiber filaments are adhered together when the glass fiber filaments are wound for a long distance is avoided; moreover, the conveying belt is matched with the winding drum to convey the glass fiber filaments, so the glass fiber filaments are prevented from being pulled strongly, and the quality and the strength of the glass fiber filaments are guaranteed.

Description

technical field [0001] The invention relates to the field of glass fiber reinforced plastic material production, in particular to a glass fiber reinforced plastic material manufacturing process. Background technique [0002] FRP, that is, fiber reinforced plastics, generally refers to glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix, glass fiber or its products as reinforced plastics, called glass fiber reinforced plastics, FRP has light weight It has the advantages of high strength, corrosion resistance, good thermal performance, and good designability. Among them, glass fiber wire is a material made of FRP, which is transported to the outer wall of the core layer for winding and forming during FRP processing. [0003] Among the cases based on the production of FRP materials disclosed in the prior art, the patent application number is CN201910822421.5, a Chinese invention patent, a manufacturing process of FRP materials, which consists of ...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of glass fiber reinforced plastic material production and manufacturing process, to solve the above-mentioned background technology in the prior art after the glass fiber cloth is cut into shreds, when using the winding device to wind up the glass fiber filaments, the after-cutting The glass fiber filaments are relatively thin and have not been completely cooled. During winding and conveying, the glass fiber filaments may be entangled or adhered together, resulting in agglomeration, which will cause the cut glass fiber filaments to bond together again, affecting the quality of the glass. The use of fiber filaments, and the pulling and winding of glass fiber filaments in the winding device will cause the glass fiber filaments to be stretched, resulting in changes in the diameter of the glass fiber filaments, which will affect the strength of the glass fiber filaments
