Instant superfine solid blocky carbon black as well as preparation method and application thereof

Abstract

The invention discloses instant superfine solid blocky carbon black as well as a preparation method and application thereof. The preparation method comprises the steps of pre-mixing powdery carbon black, an anionic surfactant, a nonionic surfactant, a interfacial agent and water, grinding through zirconium oxide, and preparing nano carbon black emulsion with the carbon black particle size not larger than 200 nm; and drying and forming to obtain solid blocky carbon black. The technical scheme provided by the invention has the advantage of no dust pollution, can be conveniently used, and can be quickly dissolved into blocky carbon black which has excellent application performance, is applied to the surface of a material by adopting conventional methods such as padding, coating and the like, and then is dried to prepare a carbon black modified material.

Description

technical field [0001] The invention relates to a preparation technology of a carbon-based material, in particular to the preparation of an environment-friendly solid block carbon black to solve the dust pollution of the existing powdery carbon black. Background technique [0002] Carbon black is an amorphous carbon that is a light, fluffy, very fine black powder with a very high surface area. Carbon black has the advantages of low price and wide source of raw materials, but there is serious carbon black dust pollution in the process of production, processing, packaging and transportation of carbon black, which not only deteriorates the production environment, but also seriously affects the health of production workers. In the application process of carbon black powder, there are also problems of carbon black dust pollution and deterioration of the production environment, and according to application requirements, powdered carbon black needs to be processed such as emulsific...

AI Technical Summary

Problems solved by technology

Carbon black has the advantages of low price and wide source of raw materials, but there is serious carbon black dust pollution in the process of production, processing, packaging and transportation of carbon black, which not only deteriorates the production environment, but also seriously affects the health of production workers

In the application process of carbon black powder, there are also problems of carbon black dust pollution and deterioration of the production environment, and according to application requirements, powder carbon black needs to be processed such as emulsification and dispersion, which is extremely inconvenient to use

In order to reduce the environmental pollution of powdered carbon black, carbon black compressors and block carbon black processing devices are used to make block carbon black through mechanical compression (ZL200520033701.1) or extrusion (ZL201820897798.8) to solve the existing Reports on the technical problems that the technology is easy to be scattered in the process of storage and transportation to pollute the environment, and seriously endanger the health of operators in the process of packaging and use

However, in the process of use, there are still deficiencies such as the need to emulsify and disperse powdered carbon black.
