After the ultrasonic is completed, deionized water with hydrophobic groups and The carbon black mixture is stirred with a high-speed mixer, and the rotating speed is 1000r / min. After the stirring is completed, the surface of the carbon black is provided with hydrophilic groups;

[0024] (3) The carbon black with the hydrophilic group is emulsified by an emulsifier, the emulsification speed is 3000r / min, the emulsification time is 20min, and the carbon black slurry is obtained after the emulsification is completed.

Embodiment 3

[0026] (2) adopt high-speed shearing machine under the situation of room temperature with the mixture of deionized water and boric acid ester and phosphoric acid ester high-speed shear with the mass concentration of 3%, shear speed is 1800r / min, and shear time is 15min, makes Deionized water has hydrophobic groups;

[0027] (2) Deionized water and carbon black with hydrophobic groups are blended at a mass ratio of 5:1, and then ultrasonic waves are used,

[0028] The ultrasonic time is 18min. After the ultrasonic is completed, the mixture of deionized water and carbon black with hydrophobic groups is stirred with a high-speed mixer.

[0029] Mix, and the rotating speed is 1000r / min, after the stirring is completed, the carbon black surface is provided with hydrophilic groups;

[0030] (3) The carbon black with the hydrophilic group is emulsified by an emulsifying machine, the emulsification speed is 3000r / min, the emulsification time is 25min, and the carbon black slurry is o...

Abstract

The invention relates to the technical field of carbon black size preparation and discloses a method for preparing size by carbon black wet method processing. The method includes steps of adopting a shearer to shear deionized water and a modifier, enabling the deionized water to carry hydrophobic groups; blending the deionized water with the hydrophobic groups with carbon black; adopting ultrasonic ultrasound, stirring, and emulsifying to form carbon black size. By the preparation method, the carbon black can be well dispersed in rubber and presents characteristics of a nano material. The carbon black size prepared by the method can serve as black water-soluble environment-friendly carbon black size to meet various dyeing needs, and long-time storage and zero precipitation of the carbon black size can be maintained.

Description

technical field [0001] The invention relates to a method for preparing carbon black slurry, in particular to a method for preparing slurry by wet treatment of carbon black. Background technique [0002] Carbon black is composed of carbon, but it is usually classified as inorganic pigments. Carbon black is a black powdery substance formed by incomplete combustion or thermal decomposition of hydrocarbons in the gas phase. Due to different production processes, various process conditions can be obtained. A variety of products with different properties, according to the performance of carbon black, there are "reinforcing carbon black", "conductive carbon black", "wear-resistant carbon black", etc., and can also be used as black dyes for the manufacture of Chinese inks, printing inks, paints, etc. It is also used as a reinforcing agent for rubber. At present, the wet mixing technology of rubber is becoming more and more mature, and some products have emerged, and wet mixing is o...
