Dispersant used for solvent-based paint, and application method thereof

The invention discloses a dispersant used for a solvent based-paint, and an application method of the dispersant. The dispersant is a light yellow liquid with a density of 1.05 to 1.10, a viscosity greater than or equal to 300Mpa.s, and a pH value of 3 to 4. The application method of the dispersant is that: first, the dispersant is diluted by an organic solvent, wherein a volume ratio of the dispersant to the organic solvent is 1:1; the diluted dispersant is added to a pigment an a filling material, and the resulting material is grinded and dispersed, such that an emulsion is obtained; the emulsion is then added to the solvent-based paint, such that the paint can be used. According to the invention, with the dispersant, the dispersibility and anti-precipitation capacity of various phthalocyanin pigments and metal pigments in an organic phase can be improved; the system viscosity of inorganic substances in an organic phase is substantially reduced, and the filling amount of the inorganic substances is increased. With the method, the tinting strength and the reflectance of the paint can be improved, and the caking property of organic polymers to various metals, glasses, concretes and inorganic materials can be improved. With the method, the leveling effect of the paint is good, and the paint is sagging resisting.
