Abstract

The invention discloses high-strength glass fiber reinforced plastic and a preparation method thereof, and relates to the field of fiber reinforced plastics. The high-strength glass fiber reinforced plastic comprises the following raw materials: unsaturated polyester, polyester glass fiber reinforced plastic waste, glass fiber, a silane coupling agent, an ethylene-butylene copolymer, an antioxidant, a weather-proof auxiliary agent, a peroxide curing agent and an accelerant. The unsaturated polyester comprises isophthalic unsaturated polyester and vinyl resin. The preparation method of the high-strength glass fiber reinforced plastic comprises the following steps: heating the unsaturated polyester, the polyester glass fiber reinforced plastic waste and the ethylene-butylene copolymer to a molten state while stirring to obtain a material A; adding the glass fiber, the silane coupling agent, the antioxidant, the weather-resistant additive, the peroxide curing agent and the accelerant into the material A, stirring for reaction, pouring and curing to obtain the glass fiber reinforced plastic. According to the glass fiber reinforced plastic, the waste polyester glass fiber reinforced plastic is effectively utilized, resource waste is reduced, and meanwhile the tensile strength is high.

Description

technical field [0001] The invention relates to the field of fiber-reinforced plastics, in particular to a high-strength glass fiber reinforced plastics and a preparation method thereof. Background technique [0002] FRP, also known as fiber reinforced plastic, is generally made of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin. Among them, FRP has the advantages of light weight, high strength, corrosion resistance, etc., and can replace some machine casings, valves, pipes, etc. made of steel. [0003] At present, with the continuous advancement of urbanization, the demand and output of FRP are increasing. But at the same time, a large amount of FRP waste is inevitably generated. If these FRP wastes are directly landfilled, it will not only cause waste of resources, but also easily cause environmental pollution, because these FRP wastes are difficult to be completely degraded in the natural environment. [0004] In order to reduce environment...
