Abstract

The invention discloses a processing technology of low-energy-consumption environment-friendly carbon black. Pre-treated carbon black and graphene are compounded by taking polyvinyl alcohol 600 as a binder to prepare environment-friendly carbon black, in this way, other toxic binders are avoided, greenness and environmental protection of the carbon black preparation technology are ensured, and meanwhile, no high-power equipment is used for treatment, so that the energy consumption of the carbon black preparation is reduced, the modified carbon black and the reinforcing agent are prepared during the preparation process, the reinforcing agent molecule contains a large amount of hindered amine and hindered phenol structure, the generated free radical or hydroperoxide decomposition can be promoted, the chain reaction can be prevented and the free radical reaction can be eliminated when the reinforcing agent is blended with the rubber, free radicals can generate stable substances to achieve an anti-aging effect, and meanwhile, a mercaptobenzothiazole structure on a molecule can participate in a vulcanization cross-linking reaction of rubber, so that the interaction between the environment-friendly carbon black and rubber quality inspection is enhanced, the reinforcing effect is improved, and the dispersity of filler is promoted.

Description

technical field [0001] The invention relates to the technical field of carbon black preparation, in particular to a processing technology of low energy consumption and environment-friendly carbon black. Background technique [0002] Carbon black is widely used in plastic products due to its good light resistance, heat resistance and antistatic properties. In the application of plastic products, compared with adding carbon black directly, carbon black masterbatch with plastic as the carrier is used It can be better dispersed in plastics, and the blackness of carbon black masterbatch is directly related to the particle size of carbon black. The smaller the particle size, the larger the specific surface area, and the higher the blackness of carbon black. This is because although the primary particles It has been fused into a primary aggregate, but its specific surface can still function. The finer the primary carbon black particles, the larger the specific surface area of ​​the...
