Abstract

The invention discloses a foaming material used for damping of automobile interior panels. The foaming material comprises the following raw materials including, by weight, 60-90 parts of polypropylene resin, 36-45 parts of an ethylene-vinyl acetate copolymer, 18-26 parts of polyurethane rubber, 20-36 parts of butadiene styrene rubber, 12-18 parts of a silane coupling agent, 5-18 parts of sodium bicarbonate, 36-66 parts of distilled water, 2-6 parts of a foaming agent and 0.5-1.5 parts of a stabilizer. In this way, the foaming material used for damping of the automobile interior panels is excellent in abrasion resistance and efficient in resilience, damping can be effectively achieved, and the safety of a driver and passengers is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile interior trim parts, in particular to a foam material for shock absorption of automobile interior trim panels. Background technique [0002] Automotive interior parts generally refer to parts and materials such as partitions, door trim panels, instrument panel assemblies, armrests, and carpets in the car compartment. [0003] The quality of automotive interior parts depends on the material. In the past, materials such as metal, wood and fiber textiles were mostly used for car interior parts, and the appearance and texture were not ideal. With the increasing awareness of environmental protection, it has become the research and development content of the automobile manufacturing industry in various countries to find some materials that can be recycled, have high material safety performance and convenient processing to replace traditional materials. [0004] At present, there are more and more ca...
