Abstract

The invention relates to an improved rubber material for an automobile. The improved rubber material for automobile comprises the following components in parts by weight: 6-10 parts of stearic acid, 2-7 parts of sulfur, 3-8 parts of N-tertbutyl-2-benzothiazole sulfenamide, 2-6 parts of stabilizer, 4-8 parts of polyethylene wax, 1-3 parts of regulator, 5-9 parts of PE, 4-7 parts of TPE, 10-20 parts of polypropylene, 3-9 parts of nano calcium carbonate, 4-9 parts of silicone oil, 10-15 parts of EPDM, and 8-13 parts of copolypropylene. The improved rubber material for the automobile has excellent stability, can be used as various sealing parts, and also has good elasticity and certain strength.

Description

technical field [0001] The present invention relates to an improved rubber material for automobiles. Background technique [0002] In the prior art, the rubber used to manufacture auto parts is usually natural rubber. Due to the chemical structure of natural rubber itself, its ozone resistance is poor, thereby affecting the physical and mechanical properties and service life of auto parts. Now with the development of the automobile industry, the requirements for automobiles are getting higher and higher. At the same time, the requirements for auto parts are also getting higher and higher. For rubber materials used in automobiles, it is required to have good oxidation resistance and corrosion resistance. At the same time, for seals such as rubber hoses, it is also required to have stable chemical properties, be able to be used for a long time, and have certain corrosion resistance to oil stains. Contents of the invention [0003] Aiming at the deficiencies in the prior art...
