Abstract

The invention relates to a water-based auto repair paint capable of low-temperature construction and a preparation method thereof. The repair paint comprises the following components and contents by weight: 50-55 parts by weight of water-based resin, 1.5-2% dispersant, 8-10% cosolvent, and a substrate. Wetting agent 0.1-0.3, bactericidal and mildew-proofing agent 0.1-0.2, thickener 1.8-3.2, aluminum powder 6-10, deionized water 25-40. Compared with the prior art, the present invention has the advantages of low temperature construction, environmental protection and the like.

Description

technical field [0001] The invention relates to a coating, in particular to a water-based automotive repair paint capable of low-temperature application and a preparation method thereof. Background technique [0002] Water-based automotive refinish paint is a substitute for oil-based automotive refinish paint. The organic solvent in the paint is replaced by water, which greatly reduces the pollution to the atmosphere caused by the volatilization of organic solvents during production and construction. Compared with oil-based paints, although water-based paints are more environmentally friendly, there are still some disadvantages in the existing water-based car wash and repair paints. For example, water-based paints usually cannot be normally dried to form a film in an environment below 10°C, or it takes several hours to dry. time to dry completely. The length of time also depends on the ambient humidity. my country has a vast territory, spanning the cold zone, temperate zon...
