Abstract

The invention discloses an environmental-friendly flame-retardant foamed bumper material and a preparation method. The environmental-friendly flame-retardant foamed bumper material consists of the following components, namely acetonitrile polyester and a compounded material in a mass ratio of 1:1.5, wherein the compounded material comprises the following components in parts by mass: 30-40 parts of polyester 330, 30-45 parts of polyester 3360, 250-350 parts of a glass fiber, 9-12 parts of polyester 400, 3.5-4 parts of silicon oil, 1.5-1.8 parts of a catalyst HPF1, 1.0-1.5 parts of a catalyst S20, 3-3.8 parts of water and 33-39 parts of a flame retardant TPCC; the silicon oil is silicon oil AK-158. Due to reasonable proportioning of the raw materials, the prepared foamed material is good in flame retardancy and stability, a bumper made of the foamed material is not only high in fireproof security and strength, but also long in service life, the foamed material prepared from environmental-friendly raw materials in reasonable proportions is free of harmful substance, and thus the environment and human bodies are not damaged.

Description

technical field [0001] The invention relates to an environment-friendly flame-retardant foaming material for a bumper and a preparation method thereof, belonging to the field of automobiles. Background technique [0002] At present, with the development of the automobile industry and the enhancement of people's awareness of safety and environmental protection, people's requirements for auto parts have also increased significantly. As a part of safety precautions, people have stricter requirements for bumpers. High temperature resistance, high flame retardancy, high strength, light weight, and high environmental protection characteristics. The strength of traditional bumpers usually cannot achieve ideal results. In the event of an accident, it is difficult to provide ideal protection for the body and people. Also, due to poor flame retardancy, the escape time of personnel is short, and there is a great potential safety hazard. . Therefore, it is the goal that this field has...
