Abstract

The invention discloses a high-temperature-resistant oil-resistant rubber composition and a preparation method thereof. The high-temperature-resistant oil-resistant rubber composition comprises the following compositions in parts by weight: 100 parts of natural rubber, 30 parts of tetrapropyl fluoro elastomer, 16 parts of ethylene-propylene-diene rubber, 2 parts of benzoyl peroxide, 12 parts of dibutyl phthalate, 5 parts of an anti-ageing agent NBC, 6 parts of zinc oxide, 33 parts of calcium carbonate, 2.1 parts of phenol formaldehyde, and 3.6 parts of epoxy soybean oil. The prepared rubber employs natural rubber as the main raw material, is prepared by adding tetrapropyl fluoro elastomer with high-temperature resistance and ethylene-propylene-diene rubber with oil resistance, has good high-temperature resistance and oil resistance, and is further improved in mechanical properties and heat resistance. The preparation method is simple and low in cost.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a high-temperature and oil-resistant rubber composition and a preparation method thereof. Background technique [0002] Under the action of high temperature or thermal oxygen, rubber produces two kinds of changes, namely physical change and chemical change. Whether it is under the action of pure heat or thermal oxygen, it can cause the main chain of the polymer to break and the crosslink to be destroyed. Or further crosslinking occurs, followed by hardening and embrittlement of rubber. Usually, the ability of rubber to maintain its original physical properties under long-term heat aging is called heat resistance. [0003] The oil resistance of rubber refers to the ability of vulcanized rubber to resist the action of oil. When rubber products are in contact with oily substances, the oil will penetrate into the rubber, causing it to swell or increase in volume, seriously affecting ...
