Abstract

The invention provides a carbon black powder surface emulsification process which comprises the following steps: respectively diluting and stirring an emulsifier and a dispersing agent, controlling the viscosity within 15-16 seconds at normal temperature, adding the agents into a gas storage tank, filling air pressure into the gas storage tank to be 2-2.5 atmospheres, and generating spray pressure, wherein the dispersing agent is branched alkyl alcohol ether phosphatide; adding carbon black powder into a mixer, stirring, heating to the temperature of 70-80 DEG C, opening a valve of the gas storage tank, and uniformly spraying the emulsifier solution in the gas storage tank on the surfaces of the carbon black powder particles; further stirring at the temperature condition of 70-80 DEG C after the emulsifier is completely sprayed, fully volatilizing the moisture, and controlling the moisture to be less than 1.5 percent; stopping heating, thereby obtaining the carbon black powder of which the surface is emulsified, cooling to normal temperature, discharging and packaging. The carbon black surface structure and characteristics are changed, the hydrophilic property of the carbon black powder is realized, and the carbon black powder surface emulsification process can be widely applied to various water-borne system resins and contributes to environmental protection.

Description

technical field [0001] The invention relates to a carbon black powder treatment process, in particular to a carbon black powder surface emulsification treatment process. Background technique [0002] Water-based environmentally friendly coatings use water as a dispersion medium and diluent, and the raw materials used in the coating are non-toxic and harmless. They are also non-toxic and pollution-free coatings in the manufacturing process. The biggest difference from solvent-based coatings is that they use water as a solvent, which greatly reduces The emission of volatile gas from organic solvents is reduced; and water, as one of the most common resources, greatly simplifies the process of paint dilution. At the same time, this kind of functional new material is very convenient for transportation and storage. These characteristics are unmatched by organic solvent paints. . [0003] As the current chemical industry must develop in the direction of green environmental protect...
