Glass fiber reinforced plastic and production process thereof

Abstract

The invention discloses a glass fiber reinforced plastic and a production process thereof, and relates to the technical field of glass fiber reinforced plastics, wherein the glass fiber reinforced plastic is prepared from the following components in parts by weight: 100-200 parts of unsaturated polyester, 100-150 parts of epoxy resin, 100-150 parts of phenol-formaldehyde resin, 50-100 parts of glass fibers, 50-100 parts of carbon fibers, 20-30 parts of polystyrene, 30-50 parts of polyethylene, 100-200 parts of aluminum hydroxide, 100-200 parts of magnesium hydroxide, 1-5 parts of a curing agent, 1-2 parts of a coupling agent, 1-2 parts of a lubricant dispersant, 1-4 parts of a compatibilizer and 100-200 parts of rock flour. A plastic mold is selected from an internal-external double-layermold, a plastic raw material of the carbon fibers is wrapped outside a plastic raw material of the glass fibers, and the alkali-free glass fibers are used. The glass fiber reinforced plastic has the glass fiber advantages of high strength, good corrosion resistance and good electrical insulation, and also has the carbon fiber advantages of high elastic modulus and high heat resistance; at the sametime, a flame retardant is added to the material to ensure that the plastic is not burned at high temperature and the overall performance and quality of the plastic are improved.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a glass fiber reinforced plastic and a production process thereof. Background technique [0002] Glass fiber reinforced plastic is a composite material with various varieties, different properties and wide uses. It is a new functional material made of synthetic resin and glass fiber through a composite process. [0003] FRP material has the characteristics of light weight, high specific strength, corrosion resistance, good electrical insulation performance, slow heat transfer, good thermal insulation performance, good instantaneous ultra-high temperature resistance, easy coloring, and electromagnetic wave transmission. Since FRP products can be designed and manufactured according to different use environments and special performance requirements, as long as the appropriate raw material is selected, it can basically meet the performance requirements of var...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a glass fiber reinforced plastic and its production process, which solves the problem that the current glass fiber reinforced plastic has a small elastic modulus and poor long-term temperature resistance, so that the outer surface has low flame retardancy and the layer The inter-shear strength is low. Although glass fiber reinforced plastics do not have the high elastic modulus, high heat resistance and low density of carbon fiber reinforced plastics, the cost of carbon fiber is high, which is not conducive to production and processing.
