[0002] White carbon black, also known as precipitated hydrated silica, is an amorphous white powder. It is commonly used in tires, soles, rubber, silicone rubber and other fields to improve their strength, rebound, wear resistance, etc. Since there are a large number of hydroxyl groups on the surface of white carbon black, when white carbon black is dispersed in organic materials such as rubber and silicone rubber, it must be treated with surface modifiers such as silane coupling agents, which increases the processing time of rubber and silicone rubber. By modifying the surface of white carbon black in advance, the processing efficiency of downstream customers as well as the reinforcement and dispersibility of white carbon black can be greatly improved.

[0003] At present, there are two common modification methods: wet modification and dry modification:

[0004] 1. Wet modification is to disperse silica in a solvent and then add relevant modifiers for surface modification. After modification, silica is more uniform, but wet modification has the problems of large amount of modifier and secondary drying of silica;

[0005] 2. Dry modification is to mix the modifier and silica in a modifier or high-speed mixer to achieve surface modification of silica. Currently, dry modification has problems such as intermittent production, easy aggregation of silica during the modification process, inability to produce continuously on a large scale, and high labor intensity.
