Problems solved by technology

[0002] The structural feature of the air bag is a capsule with a small mouth and a large body. It is difficult to release this type of product. The rubber material of the general oil-resistant air bag is mainly nitrile rubber, but the elongation at break of ordinary nitrile rubber is not high. , The tearing strength is not high, and the tearing performance is not high, so that the "burst" phenomenon is prone to occur when the air bag product is released, resulting in waste products and increasing production costs

Abstract

The invention relates to high strength and high elastic oil resistant rubber. The oil resistant rubber has high strength, good elasticity and wide temperature range while the strength and oil resistance can be ensured. The rubber comprises the following components in parts by weight: 100 parts of hydrogenated nitrile-butadiene rubber, 10-20 parts of heat stabilizer, 10-15 parts of plasticizer, 10-25 parts of reinforcing agent, 1-2 parts of vulcanizing agent, 1-5 parts of crosslinking aid and 2-5 parts of peroxide vulcanizing agent. The oil resistant rubber of the invention uses hydrogenated nitrile-butadiene rubber to replace common nitrile-butadiene rubber, uses nanometer reinforced material as auxiliary material and also adopts a special vulcanizing system. hydrogenated nitrile-butadiene rubber has good oil resistance; as the hydrogenated nitrile-butadiene rubber has a highly saturated structure, the hydrogenated nitrile-butadiene rubber has good heat resistance, good chemical resistance, excellent ozone resistance and higher compression set resistance; and the hydrogenated nitrile-butadiene rubber is also characterized by high tensile strength, high elongation at break, high tearing resistance, wear resistance and the like. The rubber of the invention can be used to produce the oil resistant air dome, solve the breakage phenomenon and save the production cost.

Description

technical field [0001] The invention relates to a rubber material with high strength, high elasticity, oil resistance and wide temperature adaptability range, in particular to a rubber formula for an oil-resistant air bag on an oil field mud pump. Background technique [0002] The structural feature of the air bag is a capsule with a small mouth and a large body. It is difficult to release this type of product. The rubber material of the general oil-resistant air bag is mainly nitrile rubber, but the elongation at break of ordinary nitrile rubber is not high. , The tearing strength is not high, and the tearing performance is not high, so that the "burst" phenomenon is prone to occur when the air bag product is released, resulting in waste products and increasing production costs. Contents of the invention [0003] Aiming at the above problems, the present invention provides a high-strength, high-elasticity oil-resistant rubber with high strength, good elasticity and wide t...
