Abstract

The invention discloses foamed plastics for automobile interior and a preparation method thereof. The foamed plastics for the automobile interior is prepared from the following raw materials in partsby weight: 90 to 125 parts of melamine resin, 8 to 18 parts of polyvinyl acetal, 16 to 25 parts of starch, 14 to 20 parts of cellulose, 6 to 12 parts of a surfactant, 6 to 10 parts of a foaming agent,2 to 4 parts of a coupling agent, 13 to 16 parts of a curing agent, 7 to 12 parts of methacrylic acid, 10 to 20 parts of methyl benzoate, 13 to 18 parts of acrylonitrile and 5 to 8 parts of citrus. The foamed plastics for automobile interior is wide in raw material source and simple in preparation process; under a synergistic effect of various raw materials, the prepared finished product has highcompressive strength and impact strength, also has a good sound absorbing effect, and meets using requirements of people.

Description

technical field [0001] The invention relates to the field of plastics, in particular to foamed plastics for automobile interior decoration. Background technique [0002] With the rapid development of my country's economic level and the development of science and technology, more and more families have private cars. It is very common for a family to have multiple vehicles. Cars have become a daily means of transportation for people. A car is a non-track-bearing vehicle driven by power and has 4 or more wheels, mainly used to carry people and goods, and tow vehicles that carry people and goods. In recent years, my country's automobile industry has developed rapidly, and cars have shown explosive growth. With the rapid development of automobiles, the lightweight and comfort of automobiles have increasingly become the focus of people's attention. As an important part of a car, automotive interior materials have attracted enough attention. [0003] At present, polyurethane foa...
