Abstract

The invention relates to the field of automobile plastic and discloses a flame-retardant high-temperature modified nylon material for automobile plastic. The material is prepared from 100-120 parts of nylon resin, 4-6 parts of inorganic filler A, 4-6 parts of inorganic filler B, 10-12 parts of polyurethane-graphene composite light foam filler, 1-2 parts of coupling agent, 1-3 parts of polyethylene wax, 0.5-1.5 parts of antioxidant, 2-4 parts of nano bamboo fiber and 1-2 parts of calcium sulfate whiskers. The inorganic filler A is selected from at least one of mullite powder, spinel powder, white corundum powder and magnesite powder. The inorganic filler B is selected from at least one of hollow glass microspheres, sepiolite powder, halloysite powder, shell powder and vermiculite powder. The prepared modified nylon material has excellent flame retardancy, high temperate resistance and physical properties, density is not obviously increased, and the nylon material has excellent denoising and heat-isolation effects and antistatic performance.

Description

technical field [0001] The invention relates to the field of plastics for automobiles, in particular to a flame-retardant and high-temperature-resistant modified nylon material for automobile plastics. Background technique [0002] With the continuous improvement of people's living standards, automobiles have gradually entered thousands of households, and the automobile industry has also achieved considerable development. At the same time, people's requirements for various parts of automobiles are also getting higher and higher. [0003] On the basis of maintaining the safety performance of automobiles, it is an important direction to realize the lightweight production of automobiles. Therefore, many auto parts are made of plastic materials, but because plastics have poorer flame retardancy and high temperature resistance than metal materials, how to effectively improve the flame retardancy and high temperature resistance of plastics is very critical. [0004] The applicat...
