Technical Field

The invention relates to the field of nitrile rubber, in particular to nitrile rubber meeting the Reach environmental protection requirement.

Background

Nitrile rubber is widely used for manufacturing various oil-resistant rubber products, various oil-resistant gaskets, sleeves, flexible packages, flexible rubber tubes, printing and dyeing rubber rollers, cable rubber materials and the like, and becomes an essential elastic material in the industries of automobiles, aviation, petroleum, copying and the like. With the continuous development of society, people pay more and more attention to the protection of the environment, the environmental protection of the rubber industry is important, and the European Union has Reach regulations and needs to meet the environmental protection requirements. The nitrile rubber is more environment-friendly while the performance needs to be ensured. Therefore, it is necessary to solve this problem.

Disclosure of Invention

In order to solve the problems, the invention provides a nitrile rubber meeting Reach environmental protection requirements, which adopts nitrile rubber, zinc oxide, stearic acid, an anti-aging agent, fast extrusion carbon black, trioctyl citrate, sulfur and an accelerator, and also comprises: the anti-scorching agent, the gas-mixing carbon black and the plasticizer DY-19, the anti-aging agent is an environment-friendly antioxidant, the accelerator is an environment-friendly tetrabenzylthiuram disulfide accelerator, and the whole formula selects environment-friendly materials, so that the performance is ensured, the requirements of the European Union Reach regulations are met, and the problems in the background art are solved.

The invention aims to provide nitrile rubber meeting the Reach environment-friendly requirement, which comprises the following components in parts by weight:

80-110 parts of nitrile rubber, 2-8 parts of zinc oxide, 1-3 parts of stearic acid, 3-9 parts of an anti-aging agent, 40-60 parts of fast extrusion carbon black, 10-20 parts of trioctyl citrate, 1-5 parts of sulfur, 2-9 parts of an accelerator, 2-5 parts of a scorch retarder, 10-20 parts of gas-mixed carbon black and 10-195 parts of a plasticizer DY-195.

The further improvement lies in that: the anti-aging agent is prepared by mixing an environment-friendly antioxidant and water in an antioxidant preparation tank.
