Abstract

The invention relates to a rubber composite, comprising nitrile rubber, polyvinyl chloride, carbon soot, activator, vulcanizator, age inhibitor, antiscorcher, accelerant and plasticizer, wherein, the plasticizer is ethylhexyl sebacate and adipate. The rubber composite of the invention obviously improves the anti-low temperature performance of the rubber composite while ensuring the anti-oil performance, anti-ozone performance, tensile strength and elongation at break.

Description

technical field [0001] The present invention relates to a rubber composition, more specifically, to an oil-resistant and low-temperature resistant rubber composition. Background technique [0002] Rubber containing nitrile rubber and polyvinyl chloride is widely used in wire and cable jackets, fuel hoses and automotive molded parts due to its oil resistance of nitrile rubber and ozone resistance of polyvinyl chloride. [0003] For example, CN200510048158 discloses an oil, acid and alkali resistant mixing material and a preparation method thereof, the mixing material includes 40-60 parts by weight of chlorinated polyethylene rubber, 40-60 parts by weight of nitrile rubber / polyvinyl chloride (70 / 30) alloy, the oligomer fat of 10-20 weight part, the zinc methacrylate of 3-8 weight part, the magnesium methacrylate of 3-8 weight part, the filler of 80-130 weight part, 1-2 Accelerator in parts by weight, vulcanizing agent in 1.5-3.5 parts by weight and plasticizer DOP in 10-20 pa...
