Problems solved by technology

[0002] Rubber, also known as elastomer, is a polymer with high elasticity. The rubber industry is one of the important basic industries of the national economy. The necessary materials. In recent years, the development trend of the rubber industry is gratifying. With the continuous expansion of production scale, the rubber industry occupies an important position in my country's industrial economy, but rubber itself also has some problems, such as its Anti-aging effect is not good
[0003] At present, the common way to improve the anti-aging effect of rubber is to add anti-aging agent 4020NA, anti-aging agent D, anti-aging agent RD and anti-aging agent 124, anti-aging agent MB, anti-aging agent NBC and other substances to the rubber components, but these substances are mixed with rubber After a long time, these anti-aging agents will be precipitated from the rubber, which will affect the anti-aging effect of the rubber.
[0004] In addition, there is also the practice of adding graphene to rubber. Graphene has a certain anti-aging effect, and compared with common anti-aging agents, it has better stability in rubber. However, when graphene is mixed with rubber, it is extremely difficult. It is prone to uneven dispersion, which greatly reduces the anti-aging effect of graphene in rubber

Abstract

The invention relates to the technical field of synthetic rubber, and discloses rubber containing modified graphene, which comprises the following components: rubber, carbon black, zinc oxide, stearic acid, sulfur, an accelerant, a scorch retarder and modified graphene. The modified graphene is obtained by fully mixing and ball-milling graphite and a modifier, then adding tert-butyl nitrite and a solvent, mixing and ball-milling, fully mixing, washing and drying; and the modifying agent is one or more of amino propionyl aniline, 4-aminobenzoyl aniline, 2-amino-N-cyclohexyl-N-methyl benzene methylamine, 4-(4-isopropyl piperazine-1-yl) aniline, (4-aminobenzene)-4-(4-methoxyphenyl) piperazine, (4-(4-aminobenzyl) piperazine-1-yl) ethanone and (4-aminobenzene)-4-(4-methoxyphenyl) piperazine. Rubber formed by mixing and refining the modified graphene and other components of rubber has a better anti-aging effect.
