Abstract

The invention discloses high-temperature-aging-resistant rubber and belongs to the field of materials. The rubber is prepared from natural rubber, chloroprene rubber, butadiene-acrylonitrile rubber, a performance additive, zinc oxide, stearic acid, carbon black, mica powder, iso-propyl xanthogen disulfide, microcrystalline wax, sulphur, 2,2'-thiodiglycol, 3-5 parts of epoxy fatty acid polyol ester and rosin texanol ester alcohol. The performance additive comprises 2-heptadecyl-N-aminoethyl imidazoline epoxypropane, polybenzimidazole benzophenanthrene phenanthroline and polyquinoline. 2-heptadecyl-N-aminoethyl imidazoline epoxypropane, polybenzimidazole benzophenanthrene phenanthroline and polyquinoline serve as the performance additive, and the high-temperature-aging resistance of the rubber is greatly improved. When iso-propyl xanthogen disulfide serves as an accelerant, 2,2'-thiodiglycol serves as an anti-aging agent, and a combination of epoxy fatty acid polyol ester and rosin texanol ester alcohol serves as a plasticizer, the high-temperature-aging resistance of the rubber is more excellent.

Description

technical field [0001] The invention relates to the field of materials, in particular to a high-temperature aging-resistant rubber. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable to people's daily life, but also provides various rubber production equipment or rubber parts for mining, transportation, construction, machinery, electronics and other heavy industries and emerging industries. It can be seen that the rubber industry has a wide variety of products, and the backward industry is very broad. In recent years, the rubber industry has developed a lot. The existing sub-sectors have grown steadily, while the new rubber sub-sectors have developed rapidly. However, at the same time, the rubber industry still has problems such as the environment, resources, disasters, and innovation. [0003] As we all know, one o...
