Flame-retardant automobile damping rubber shock absorption component material

Abstract

The invention discloses a flame-retardant automobile damping rubber shock absorption component material. The flame-retardant automobile damping rubber shock absorption component material comprises, byweight, 20-30 parts of polyurethane rubber, 20-25 parts of epoxidized butyl rubber, 20-25 parts of graphene-polyvinyl chloride composite materials, 4-7 parts of carbon nano-tubes, 2-5 parts of toughening agents, 2-4 parts of antioxidants, 1-4 parts of anti-aging agents, 1-3 parts of damping reinforcing agents, 3-9 parts of polyvinyl silicone oil, 3-6 parts of maleic anhydride compatilizer, 3-7 parts of paraffin, 5-8 parts of microcrystalline celluloses, 2-5 parts of acetylene carbon black, 1-3 parts of stearic acid, 2-5 parts of accelerators, 2-4 parts of cross-linking agents, 1-2 parts of flame retardants and 3-7 parts of olefin elastomers. The flame-retardant automobile damping rubber shock absorption component material has the advantages that the polyurethane rubber and the epoxidizedbutyl rubber are used as main raw materials for the flame-retardant automobile damping rubber shock absorption component material, other accessories are added into the main raw materials, accordingly,rubber compounds are good in toughness and flame retardance, high in strength and excellent in ant-aging performance, and are light, and the requirements on the mechanical properties, the elasticityand kinetic energy absorption which are required by shock absorption components can be met.

Description

technical field [0001] The invention relates to the field of automobile processing, in particular to a flame-retardant automobile damping rubber shock absorber material. Background technique [0002] With the rapid development of modern industry, vibration and noise have become serious problems in various fields. It will reduce the operating accuracy, affect product quality, shorten product life, make high-precision instruments not work normally, and endanger safety. [0003] In the processing and manufacturing of automobiles, the shock absorber is one of the essential parts. It is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface, which plays a role in the comfort and handling stability of the vehicle. important role. The principle of the existing shock absorber bushing is to convert the mechanical energy of vibration into thermal energy through the elastic support and dissipate it to the surrounding e...
