Embodiment 1

[0023] The fiber-reinforced flame-retardant plastics provided by the embodiments of the present invention are mainly used as polyester, polyester, and the general term for polymers obtained by polycondensation of polyhydric alcohols and polybasic acids. It mainly refers to polyethylene terephthalate (PET), and customarily also includes linear thermoplastic resins such as polybutylene terephthalate (PBT) and polyarylate. It is a kind of engineering plastic with excellent performance and wide application. It can also be made into polyester fiber and polyester film. Polyester includes polyester resins and polyester elastomers. Polyester resins include polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and polyarylate (PAR). Polyester elastomer (TPEE) is generally polymerized from dimethyl terephthalate, 1,4-butanediol and polybutanol. The chain segment includes hard segment and soft segment, and is a thermoplastic elastomer.

Abstract

The embodiments of the invention disclose a fiber reinforced flame-retardant plastic and a preparation method thereof. The fiber reinforced flame-retardant plastic is used for solving the problems that the charging pile socket material in the prior art declines too fast on outdoor using performance, is insufficient in flame retarding, weak in impact resistance, easy to deform in long-time use, and the like. The fiber reinforced flame-retardant plastic comprises the following components in parts by weight: 70-80 parts of polyester, 20-35 parts of inorganic filling powder, 6-10 parts of flexibilizer, 20-30 parts of fibers, 5-10 parts of flame retardant and 1-5 parts of other components, wherein the other components comprise one or more of antioxidant, lubricant, coupling agent and anti-UV agent. The fiber reinforced flame-retardant plastic is safe, reliable, high-temperature resistant, stable in thermal deformation size and convenient to process, and can be used outdoors for a long term.

Description

technical field [0001] The invention relates to the technical field of modified engineering plastics, in particular to a fiber-reinforced flame-retardant plastic and a preparation method thereof. Background technique [0002] With the improvement of environmental protection awareness, electric vehicles and charging piles have gradually entered the lives of the public, and the stylish and elegant appearance design has become the only way for hundreds of charging equipment manufacturers to differentiate. Car charging piles are designed to solve people's rigid needs, and they will naturally be used in complex environments. There are 6 parts of the charging pile shell that can use plastic, namely the charging pile shell, charging pile plug, charging pile socket, charging gun shell, circuit breaker, contactor and power module shell, and the shell materials of different parts have corresponding Material selection requirements, not only to meet the performance requirements, but al...
