Technical Field

The invention relates to the field of rubber manufacturing, in particular to a 100pphm high-concentration ozone-resistant nitrile rubber.

Background

At present, in various fields, rubber is used as a material for preparing a conveying belt or other products, and butadiene acrylonitrile rubber is favored by vast product manufacturers as one kind of rubber, but with special requirements of a use environment, the requirement on butadiene acrylonitrile rubber is higher and higher, in the special environment, the butadiene acrylonitrile rubber is required to have higher ozone tolerance, and butadiene acrylonitrile rubber made of a common material has no advantage in ozone tolerance and can only meet general use requirements. Therefore, it is very important to solve the problem that the butadiene acrylonitrile rubber made of common materials has no advantage in ozone tolerance.

Disclosure of Invention
