Abstract

The invention discloses a preparation method of a high-content carbon black master batch. According to the method, modified polystyrene reacts with modified carbon black particles, and then melting and extruding are conducted with liquid paraffin, graphite, kaolin powder and sodium dodecyl benzene sulfonate; and modified polystyrene is dissolved in N,N-dimethylformamide to react with modified carbon black particles, so that chlorine atom sites on the modified carbon black particles are subjected to cross-linking reaction with the modified polystyrene, thereby ensuring that the modified carbon black particles are stably attached to the modified polystyrene and do not fall off when the content of the carbon black is increased. The surface of the modified carbon black particle is grafted with an oxyacid structure containing phosphorus in molecules, a continuous and compact carbon layer can be formed on the surface when the carbon black master batch is combusted, heat and oxygen can be isolated, smoke and molten drops can be inhibited, and phenothiazine structures in the molecules further improve the anti-aging performance of the carbon black master batch.

Description

technical field [0001] The invention relates to the technical field of polymer material preparation, in particular to a method for preparing a high-content carbon black masterbatch. 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, the carbon black masterbatch with plastic as the carrier can be better dispersed in the plastic. 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 have been fused into primary aggregates, their specific surface can still function. The finer the primary carbon black particles, the larger the specific surface area of ​​the aggregate, the darker the color,...
