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.

Embodiment 1

[0048] 1000 grams of carbon black 15F, 96 grams of dispersant MF, 97 grams of sodium lignosulfonate-N, 34 grams of octadecylamine polyoxyethylene ether (EO=15), 33 grams of Pingpingjia O15 (EO=15), 34 Pre-mix 6 grams of polyether polyol HSH-210, 6 grams of dispersant RQT-FS and 8700 grams of water to prepare a carbon black solution, with a total of 300 grams of additives. The carbon black solution was continuously ground for 2 hours in a zirconia ball mill to obtain a carbon black emulsion. The above-mentioned nano-carbon black emulsion is placed in a container and dried to obtain solid block carbon black.

Embodiment 2

[0050] 1000 grams of carbon black F15, 82 grams of dispersant MF, 81 grams of sodium lignosulfonate-N, 41 grams of octadecylamine polyoxyethylene ether (EO=15), 41 grams of Pingpingjia O15 (EO=15), 41 The carbon black solution was prepared by pre-mixing 1 g polyether polyol HSH-210, 14 g dispersant RQT-FS and 8700 g water. The carbon black solution was continuously ground for 2.5 hours in a zirconia grinding device to obtain a carbon black emulsion. The above-mentioned nano-carbon black emulsion is placed in a container and dried to obtain solid block carbon black.

Embodiment 3

[0052] 2000 grams of carbon black F15, 157 grams of dispersant MF, 157 grams of sodium lignosulfonate-N, 50 grams of octadecylamine polyoxyethylene ether (EO=15), 45 grams of Pingpingjia O15 (EO=15), 78 The carbon black solution was prepared by pre-mixing 1 g of polyether polyol HSH-210, 13 g of dispersant RQT-FS and 7500 g of water. The carbon black solution was continuously ground for 2.5 hours in a zirconia grinding device to obtain a carbon black emulsion. The above-mentioned nano-carbon black emulsion is placed in a container and dried to obtain solid block carbon black.

Abstract

The invention discloses an instant superfine solid block carbon black and its preparation method and application. The powdery carbon black, anionic surfactant, nonionic surfactant, surfactant and water are premixed, and then the Grinding zirconia to obtain a nano-carbon black emulsion with a carbon black particle size not higher than 200nm; drying and forming to obtain a solid block carbon black. The technical solution of the present invention has the advantage of no dust pollution, is convenient to use, can quickly dissolve into massive carbon black, and has excellent application performance. It is applied to the surface of the material by conventional methods such as padding and coating, and then dried , to prepare carbon black modified materials.

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...
