A device for modifying white carbon black with a surface modifier

Abstract

The invention relates to a device for modifying white carbon black with a surface modifier. The device comprises a drying tower, an elevator and a surface modifier atomizer, wherein the surface modifier atomizer is located between the drying tower and the elevator. The device for modifying the white carbon black with the surface modifier can perform surface modification on the white carbon black during production of the white carbon black, and the white carbon black produced by the device does not need surface modification any more during industrial application, so that time and processes of the white carbon black during industrial application can be reduced. With adoption of the device, the white carbon black and the surface modifier can be contacted sufficiently, and the white carbon black can be modified sufficiently. A bag deduster is arranged in the device, part of surface modified white carbon black can be recovered, and dust pollution can be reduced.

Description

technical field [0001] The invention relates to a treatment device for hydrophobic modification of white carbon black, in particular to a device for modifying white carbon black with a surface modifier. Background technique [0002] In the rubber vulcanization system, unmodified silica cannot be well dispersed in the polymer, and it is difficult to form coupling bonds between fillers and polymers, which will reduce the vulcanization efficiency and reinforcement performance. The surface modification of white carbon black is to use certain chemical substances to react the surface hydroxyl groups of white carbon black with chemical substances through certain process methods, eliminate or reduce the amount of active silanol groups on the surface, and make the product change from hydrophilic to Hydrophobic, increasing its dispersibility in polymers. [0003] Modified silica has superior properties and is widely used in rubber, paint, plastic and other industries. At present, th...

Problems solved by technology

Although the dry modification process is simple, it has the disadvantages of high energy consumption, high cost, serious dust pollution, etc., and requires special equipment. When using dry modification, the modifier is usually not evenly distributed and the effect is not ideal.

At present, most of the surface modification of silica is carried out during the rubber mixing of silica, which increases the process of rubber mixing.
