Problems solved by technology

[0002] FRP has the characteristics of corrosion resistance and light weight, and has been used in various fields. However, the high polymer material is flammable, and there are many fire hazards in use.
At present, the main method to improve the flame retardancy of FRP composite materials is to add flame retardants, but flame retardants have certain shortcomings, such as halogen-containing flame retardants, which have good flame retardant effects, but are prone to produce a large amount of harmful smoke during the flame retardant process , halogen flame retardants are phased out

Abstract

The invention discloses a high-efficiency and flame-retardation glass fiber reinforced plastic composite material. The high-efficiency and flame-retardation glass fiber reinforced plastic composite material comprises, by weight, 18-24 parts of alkali-free glass short fibers, 12-17 parts of epoxy vinyl resin, 0.4-1.1 parts of a flame retardant, 0.7-1.8 parts of cobalt octoate, 3-6 parts of aluminum hydroxide, 9-16 parts of hydrogen peroxide, 0.3-0.6 parts of dicyclopentadiene, 0.03-0.2 parts of hexamethylenetetramine, wherein the epoxy vinyl resin is one of bisphenol A epoxy vinyl ester resin and phenolic epoxy vinyl ester resin, and the flame retardant is polyphosphamide. The glass fiber reinforced plastic composite material has good chemical stability, strength and flame retardation effect.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a high-efficiency flame-retardant fiberglass composite material. Background technique [0002] FRP has the characteristics of corrosion resistance and light weight, and has been used in various fields. However, the polymer material is flammable, and there are many fire hazards when it is used. At present, the main method to improve the flame retardancy of FRP composite materials is to add flame retardants, but flame retardants have certain shortcomings, such as halogen-containing flame retardants, which have good flame retardant effects, but are prone to produce a large amount of harmful smoke during the flame retardant process , Halogen flame retardants are phased out. Therefore, the development of a safe, environmentally friendly, non-toxic and pollution-free inorganic flame retardant is the key to improving the flame retardancy of FRP composites.
