Abstract

The invention relates to an environment-friendly water-based single-component metallic-effect refinish paint for automobiles and a preparation method thereof. The refinish paint comprises the following components in percentage by weight: 30-50% of water-based resin, 3-10% of single-component metallic-effect pigment, 0.1-1.0% of water-based dispersant, 0.3-1.0% of water-based defoaming agent, 3-9% of water-based thickening agent, 1-8% of cosolvent, 0.5-1% of water-based leveling agent, 0.1% of bactericide, 1-2% of pH regulator and 30-45% of deionized water. Compared with the prior art, the invention is harmless to human bodies, and has the advantages of strong metallic texture and the like.

Description

technical field [0001] The invention relates to a repair paint for automobiles, in particular to an environment-friendly water-based automobile single-component metal effect repair paint and a preparation method thereof. Background technique [0002] At present, solvent-based refinish paints are widely used in the automotive repair market. The solvent content of traditional solvent-based refinish paints is often above 40%, and the solvent content of automotive solvent-based metallic colors is even as high as 85%. These solvents are generally volatile. Organic compounds (VOC) and volatile organic compounds (VOC) enter the atmosphere, which will cause environmental pollution and cause harm to the health of painting workers. As people pay more attention to health, car refinish paints are also developing towards health and environmental protection, and the market demand for water-based car refinish paints is gradually increasing. Contents of the invention [0003] The object ...
