Abstract

The invention discloses a water-based paint spray mist agglutinant which comprises an agent A, wherein the agent A is composed of the following components in percentage by weight: 0.1-1.0% of a flocculating agent, 0.5-3.0% of a first assistant, 0.5-5.0% of a preservative, 3.0-5.0% of a first pH regulator and the balance of a first solvent; and the sum of dosage of various components in the agent Ais 100%. Compared with the prior art, the water-based paint spray mist agglutinant disclosed by the invention has the advantages that 1, strong attraction to paint drops is produced by high charge, the paint drops are completely coated after adsorbed by utilizing different secondary affinities of the paint drops, and functional groups in the paint drops are penetrated and destructed by virtue ofchemical actions, so that viscosity is completely eliminated, the coated paint drops are driven to come up or sink, functional groups among the paint particles can be destructed by chemical reactions,so that the paint drops are destabilized, viscosity-eliminated and come up, and the aim of separating the paint drops from water is achieved; 2, the product is not influenced by the pH value during use, and the pH value does not need to be additionally regulated; and 3, the product has effects of inhibiting bacterium growth and killing bacteria, and an additional bactericide is not needed.

Description

technical field [0001] The invention relates to the field of chemical separation agents, in particular to a water-based paint mist coagulant. Background technique [0002] From the perspective of the development of the automobile industry, the selection of future automobile coatings will focus on their environmental performance while improving their performance. Water-based paint is favored by more and more painting users because of its environmental characteristics without organic solvents. It will gradually replace traditional solvent-based paint and become the mainstream of modern automobile painting. The use of water-based paint has become the general trend in the painting field. However, while water-based paint has environmental advantages, it also has its disadvantages. Due to its complete miscibility with water, it is difficult to separate it from water, and it will generate a lot of foam, which seriously affects its production. Water-based paint coating wastewater t...
