Embodiment Construction

[0016] In order to more clearly illustrate the purpose, technical solutions and advantages of the embodiments of the present invention, the present invention will be further described below in conjunction with the embodiments, and a clear and complete description will be made. Obviously, the described embodiments are part of the embodiments of the present invention. rather than all examples. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] Embodiment of the present invention, a kind of antistatic hydrogenated nitrile rubber, its preparation steps are as follows,

[0018] S1, banbury hydrogenated nitrile rubber raw rubber for 90 seconds, use ZP2010 hydrogenated nitrile rubber to prepare, weigh 30kg and banbury it for 90 seconds, and banbury can be carried out with a banbury mixer;

[0019] S2, add antioxidant...

Abstract

The invention relates to anti-static hydrogenated butadiene-acrylonitrile rubber which comprises the following components in percentage by weight: 50%-60% of hydrogenated butadiene-acrylonitrile rubber raw rubber, 0.4%-0.8% of an anti-aging agent, 1%-2.5% of polytetrafluoroethylene, 0.4%-0.8% of aramid fiber, 20%-25% of N220 carbon black, 4.5%-6.5% of conductive carbon black, 4.5%-6.5% of white carbon black, 4.5%-6.5% of talcum powder and 2%-3.5% of a plasticizer. The hydrogenated butadiene-acrylonitrile rubber also comprises the following components in percentage by weight: 10.5-12g / kg of triallyl isocyanurate, 2.5-3.2 g / kg of dicumyl peroxide and 25-30g / kg of bis (pentasulfide) based on the total component weight. A preparation method of the hydrogenated nitrile rubber is also disclosed. The resistance of the rubber is reduced, and the generation of static electricity can be prevented.

Description

technical field [0001] The invention relates to hydrogenated nitrile butadiene rubber, in particular to an antistatic hydrogenated nitrile butadiene rubber. Background technique [0002] Hydrogenated nitrile rubber (HNBR or HSN for short) is a product obtained by hydrogenation and saturation of carbon-carbon double bonds in the molecular chain of nitrile rubber, so it is also called highly saturated nitrile rubber. Hydrogenated nitrile rubber is widely used in oil fields, automobile industry, etc. With the development of automobile and petroleum industry, rubber parts must have good heat resistance, high temperature resistance, high pressure resistance, oxygen resistance, anti-static, etc. in addition to oil resistance. characteristic. Ordinary nitrile rubber (NBR) is far from meeting these requirements. For anti-static, its resistance is large, and the anti-static effect cannot be achieved. Moreover, the products made will absorb dust due to static electricity, and the use...
