Abstract

The invention discloses a processing technology of low-energy environmental protection carbon black. The environmental protection carbon black is prepared by compounding pretreated carbon black and graphene with polyvinyl alcohol 600 as a binder. This method avoids the use of other toxic adhesives. binder, which ensures the green and environmental protection of the carbon black preparation process, and at the same time does not use high-power equipment to reduce the energy consumption of carbon black preparation, and prepares modified carbon black and reinforcing agent during the preparation process. The reinforcing agent molecule contains A large number of hindered amine and hindered phenol structures, when blended with rubber, can generate free radicals, or promote the decomposition of hydroperoxides, prevent chain reactions, eliminate free radical reactions, and enable free radicals to generate stable material to achieve anti-aging effects, and the mercaptobenzothiazole structure on the molecule can participate in the vulcanization and cross-linking reaction of rubber, which enhances the interaction between environmentally friendly carbon black and rubber quality inspection, improves the reinforcing effect, and promotes the filler. dispersion.

Description

Technical field [0001] The present invention relates to the field of carbon black preparation technology, specifically to a low energy consumption environmental protection carbon black processing process. Background [0002] Carbon black has good lightfastness, heat resistance, antistatic properties and other characteristics and widely used in plastic products, in the application of plastic products, compared with the direct addition of carbon black, the use of plastic as the carrier of carbon black masterbatch can be better dispersed in plastic, 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, the higher the blackness of carbon black, this is because although the native particles have been melted into the native aggregate, but its specific surface can still work, the finer the native carbon black particles, The larger the specific surface area of the conde...
