Abstract

The invention discloses a composite material with a wide damping temperature range. The composite material with the wide damping temperature range is prepared from the following substances in parts by weight: 55 to 62 parts of emulsion polymerized butadiene styrene rubber, 17 to 29 parts of polytetrafluoroethylene, 9 to 14 parts of isoprene rubber, 3 to 9 parts of hard ethylene distearamide, 13 to 20 parts of glyceryl monostearate, 3 to 6 parts of dimethyl siloxane, 11 to 16 parts of glass fiber, 9 to 12 parts of polybutylene terephthalate, 5 to 17 parts of chlorcosane, 3 to 5 parts of N-phenyl-beta-naphthylamine, and 5.5 to 9.5 parts of aluminum acetylacetonate. The composite material with the wide damping temperature range has the characteristics of outstanding low-frequency noise reduction performance, light weight, wide damping temperature range, wide noise reduction bandwidth, ageing resistance and the like.

Description

technical field [0001] The invention relates to a composite material with a wide damping temperature range. Background technique [0002] At present, the well-known acoustic wave damping materials on the market are single-component single-layer composite damping materials made of polymer materials.
