Abstract

A wear-resistant automotive seal is made from, by weight, 9 to 15 parts of 3L rubber, 2 to 8 parts of pine tar, 7 to 9 parts of stearic acid, 8 to 14 parts of isoprene rubber, 6 to 14 parts of PA6 resin, 3 to 10 parts of black masterbatch, 9 to 15 parts of trifluoroacetylacetonate, 8 to 11 parts of ferricyanate, 6 to 8 parts of carbon black, 1 to 5 parts of vulcanizing agent, 3 to 8 parts of plasticizer, 6 to 10 parts of thermoplastic polyurethane resin, 1 to 5 parts of paraffin, 1 to 3 parts of cut-3 oil, 6 to 8 parts of poly-4-methyl-1-pentene, and 7 to 11 parts of aluminum hydroxide. The wear-resistant automotive seal is good in wear resistance, long in service life and good in toughness and elasticity.

Description

technical field [0001] The invention relates to a wear-resistant automobile sealing strip. Background technique [0002] Automobile sealing strip is one of the important parts of automobiles. It is widely used in doors, windows, body, seats, sunroof, engine box and trunk, etc. It has waterproof, sealing, sound insulation, dustproof, antifreeze, shock absorption, It plays an important role in keeping warm and saving energy. It must have strong tensile strength, good elasticity, and good temperature resistance and aging resistance. However, the existing sealing strips are difficult to meet the above requirements, the sealing effect is poor, the wear resistance and strength are not enough, and the sealing effect cannot be well achieved. Therefore, people need a high-performance sealing strip to improve the sealing performance of automobiles. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the present invention is ...
