Abstract

The invention belongs to the field of white carbon black preparation, and particularly relates to white carbon black and a preparation method and application thereof. The preparation method is capableof using a tail gas of carbon black production and the like as an acidifying agent, performing a precipitation reaction by using a stirring-auxiliary circulating-jet carbonization technology, and combining the advantages of three types of technologies of stirring, spraying and bubbling. The cost is cheap, the precipitation reaction efficiency is remarkably accelerated, and a precipitation white carbon black product of which the specific surface area is controllable can be efficiently synthesized. The preparation method is a recycling production system which is cheap in cost and green in design and manufacture, and has great industrial application value and potential social and economic benefits in the preparation industry of a tire rubber reinforcing agent.

Description

technical field

[0001] The invention belongs to the field of white carbon black preparation, and in particular relates to white carbon black and its preparation method and application. Background technique

[0002] Precipitated silica has a similar microstructure and reinforcing properties to carbon black materials. As early as the last century, researchers have begun to try to use silica to replace carbon black materials as a reinforcing agent for tire rubber. In recent years, with the promulgation and implementation of tire labeling laws in various countries and the introduction of my country's green tire technical specifications, green tires have become an inevitable trend in the development of the tire industry. Silica has become the most important reinforcing filler in the rubber formula of green tires. Can give tires low rolling resistance (less fuel consumption, can reduce car CO 2 emission) and high anti-wet skid ability (shorter braking distance of automobiles), so ...
