Oil resistant rubber

Abstract

The invention proposes oil resistant rubber, wherein the composition comprises the following components in pars by weight of 100 parts of tetrafluoropropene rubber, 1 part of sodium stearate, 2 parts of dicumyl peroxide, 1.5 parts of tert-butyl peroxide hexane, 8 parts of triallyl isocyanurate, 20 parts of carbon black N330 and 0-15 parts of stannic oxide. The rubber prepared from the composition, a preparation method and an oil resistant evaluation method are also provided, and the oil resistance of the rubber is the best when the dosage of nano tin dioxide is 5 parts.

Description

technical field [0001] The invention relates to the field of oilfield chemical industry, in particular to an oil-resistant rubber. Background technique [0002] 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 various oils in the oil field for a long time, the oil can penetrate into the rubber to make it expand or increase in volume; at the same time, the oil medium can extract soluble compounding agents (such as plasticizers) from the vulcanized rubber. agent, anti-aging agent, anti-degradation agent, etc.), resulting in shrinkage or volume reduction of the vulcanizate. Generally, the swelling increases with the contact time of the vulcanized rubber and the oil until the oil is no longer absorbed, and then the volume expansion remains stable, resulting in the expansion of the originally tightly arranged three-dimensional cross-linked network, and the performance of the rubber produ...
