Abstract

The invention discloses a high-toughness automobile sealing strip, which is prepared from the following raw materials in parts by weight: 9 to 15 parts of neoprene, 3 to 6 parts of a rare earth modifier, 4 to 9 parts of white carbon black, 3 to 10 parts of chlorinated paraffin, 1 to 5 parts of an accelerator, 6 to 11 parts of nitrile-butadiene rubber, 3 to 8 parts of sulfur powder, 9 to 14 parts of benzyl trimethyl ammonium tribromide, 6 to 9 parts of diethylene glycol monobutyl ether, 2 to 7 parts of tetrahydrofuran, 6 to 11 parts of 3-propargyl chloride, 3.5 to 8 parts of zinc stearate, 6 to 10 parts of poly-4-methyl-1-pentene, 7 to 10 parts of thermoplastic resin, 3 to 9 parts of dimethylsilicone fluid, 6 to 12 parts of butadiene styrene rubber and 2 to 9 parts of an accelerator. The automobile sealing strip has the beneficial effects of strong strength, high toughness, capability of well achieving a sealing effect and good soundproof and waterproof effects.

Description

technical field [0001] The invention relates to a high-toughness 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 ...
