Abstract

The invention discloses an oil-resistant and high-temperature-resistant rubber material for automobiles. The oil-resistant and high-temperature-resistant rubber material comprises the following raw materials in parts by weight: 45-55 parts of butadiene rubber, 20-25 parts of acrylate rubber, 20-35 parts of silicon rubber, 15-20 parts of white carbon black, 10-15 parts of modified nano talcum powder, 2-5 parts of sulfur, 0.5-1.2 parts of zinc oxide, 1-3 parts of tricresyl phosphate, 0.5-2 parts of oxidized polyethylene, 3.5-4.5 parts of a promoter TMDT, 2-5 parts of an anti-aging agent, 0.2-0.5 part of epoxy flaxseed oil, 0.2-0.5 part of triethyl o-acetylcitrate and 1.0-1.5 parts of microcrystalline wax. The rubber material disclosed by the invention is good in wear resistance, heat resistance and oil resistance, and can be applied to automobile fuel tanks.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to an oil-resistant and high-temperature-resistant rubber material for automobiles. Background technique [0002] The relationship between rubber and automobiles is extremely close. At present, more than 70% of rubber products are used in automobiles. At least 3 / 4 of the production value of the rubber industry comes from the supporting and maintenance of automobiles, and more than 1 / 3 of the economic growth point depends on the development and progress of the automobile industry. The rapid development of the automobile industry in recent years will bring unprecedented opportunities to the rubber industry, and at the same time put forward higher requirements for automotive rubber products and new materials, which will also be a huge challenge to the rubber industry. The synthetic rubber industry in the modern world is characterized by intelligent design and synthesis, and efficient ...
