Abstract

The invention discloses a flame-retardant compression-resistant composite for a glass fiber reinforced plastic septic tank and a preparation method of the flame-retardant compression-resistant composite and relates to the technical field of glass fiber reinforced plastics. The flame-retardant compression-resistant composite comprises the raw materials in parts by weight: 100 parts of unsaturated polyester resin, 3-7 parts of acrylonitrile-butadiene-styrene copolymer, 80-110 parts of glass fibers, 3-7 parts of silica powder, 20-30 parts of bentonite, 6-12 parts of epoxypropane butyl ether, 3-7parts of curing agent, 2-5 parts of accelerant, 2-5 parts of flame retardant, 0.5-2 parts of benzotriazole, 0.5-2 parts of butylbenzyl phthalate and 1-3 parts of coupling agent. The glass fiber reinforced plastic composite disclosed by the invention is relatively high in strength and toughness, compression-resistant, corrosion-resistant, good in flame retardance and weather resistance and capableof meeting the requirement for high strength of the glass fiber reinforced plastic septic tank.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced plastics, in particular to a flame-retardant and compression-resistant composite material for glass fiber reinforced plastic septic tanks and a preparation method thereof. Background technique [0002] FRP, that is, fiber-reinforced plastics, generally refers to reinforced plastics made of unsaturated polyester resin and other fillers such as glass fibers, also known as glass fiber-reinforced plastics. It has the advantages of light weight and hardness, good mechanical strength, and non-conductivity. It has been developed and applied to septic tanks and other civil fields that are conducive to ecological protection. [0003] FRP septic tanks can effectively solve the problems of leakage of traditional brick-concrete septic tanks, different degrees of pollution to groundwater sources, and tilting of buildings, and can lay the foundation for subsequent advanced treatment of discharged...
