Abstract

The invention discloses a foaming material for sound absorbing of an automobile trim plate. The foaming material for sound absorbing of the automobile trim plate comprise the raw materials, by weight, 55-75 parts of ethylene-vinyl acetate copolymer, 25-35 parts of polyester fibers, 10-20 parts of nitrile butadiene rubber, 5-15 parts of polyvinyl chloride, 25-45 parts of melamine foam, 25-65 parts of distilled water, 50-18 parts of a foaming agent and 1.2-1.6 parts of a stabilizing agent. Due to the above manner, lots of micro communicated pores exist in the foaming material for sound absorbing of the automobile trim plate, sound waves can go deep into the material along the pores, an efficient and reliable sound absorbing effect is achieved, and quietness of the indoor environment of an automobile is guaranteed.

Description

technical field [0001] The invention relates to the technical field of automotive interior parts, in particular to a foaming material for sound absorption of automotive interior 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] The current car interior panels are not obvio...
