Preparation method and application of paint-water separating agent

The invention provides a preparation method and application of a paint-water separating agent, and relates to the technical field of environmental pollution treatment. The paint water separating agent is prepared from the following raw materials in parts by weight: 20 to 25 parts of polyaniline, 15 to 18 parts of N, N-dimethylformamide, 10 to 13 parts of chitin, 5 to 6 parts of 8 percent lithium chloride solution, 20 to 25 parts of polyacrylamide with the concentration of 1 percent, 15 to 18 parts of polymeric aluminum oxide with the concentration of 3 percent, 16 to 18 parts of ethanol solution, 4 to 6 parts of ammonium bicarbonate solution, 7 to 9 parts of diethylamine sulfate, 10 to 13 parts of activated carbon and 10 to 13 parts of modified diatomite. Polyaniline is adopted as a main material of the viscosity eliminating agent A, positive charges in the polyaniline and negative charges of sprayed paint in circulating water are mutually neutralized, so that the viscosity of the paint in sewage is lost, mea
