Description

Continuous crushing apparatus of modified white carbon black

Technical Field

The invention belongs to the technical field of machinery, relates to continuous crushing equipment, and particularly relates to continuous crushing equipment for modified white carbon black.

Background

The surface treatment of the white carbon black is to eliminate or reduce the amount of surface hydroxyl groups by reacting certain chemical substances with the hydroxyl groups on the surface of the white carbon black through a certain process, so that the white carbon black is changed from hydrophilicity to hydrophobicity, and the affinity of the white carbon black with raw rubber is improved. The modifier which is most widely used at present is a silane coupling agent, and the action mechanism of the modifier is as follows: the hydrolytic groups in the silane coupling agent are hydrolyzed to generate silanol, and further the silanol is condensed with silicon hydroxyl on the surface of the white carbon black, so that the surface of the white carbon black is changed from hydrophilicity to hydrophobicity, and the compatibility of the white carbon black with rubber is improved. However, the silane coupling agent can only partially modify the white carbon black in a mixed system of a fixed shear field. Therefore, various methods are continuously sought for further improving the dispersibility of fillers such as white carbon black and improving the interaction between the fillers and silicone rubber. A small amount of dispersing agent is added, and the dispersing agent and the silane coupling agent can generate a superimposed effect in the tread rubber through a proper mixing process. The process flow of the modified white carbon black comprises the following steps: reaction, modification, washing, drying, crushing and finishing.
