Abstract

The invention relates to a metallic glitter paint, which is suitable for paint and paint enterprises, and discloses a water-based metallic glitter paint and a matching blending resin; the water-based metallic glitter paint contains the following raw materials in parts by weight: aluminum silver paste 3-20, film-forming Cosolvent 3~20, high molecular weight dispersant 0.1~1, amine neutralizer 0.1~3, metallic flash paint alignment agent 0.5~3, self-made water-based polyurethane base material 50~80, deionized water 5~30. The supporting blending resin contains the following raw materials in parts by weight: 30-70 parts by weight of water-based acrylic resin, 0.1-3 parts of amine neutralizer, 0.1-1 part of defoamer, 0.1-1 part of wetting agent, and 30-30 parts of self-made powder metal glitter paint alignment agent aqueous solution 60, deionized water 3-20. The product of the present invention has good storage stability, the organic volatile content (VOC) can be controlled below 100g / L, and the paint film obtained by using the water-based metallic glitter paint and the blended resin as a complete set has a fast drying speed, and the paint film is consistent with the water-based metallic glitter paint color. No chromatic aberration, good arrangement effect of metallic glitter paint, excellent performance.

Description

Technical field: [0001] The invention relates to a paint for automobile repair, in particular to a water-based metallic glitter paint. Background technique: [0002] The volatilization of solvents (VOC) in traditional solvent-based coatings is the third largest source of air pollution after automobile exhaust and smog, and is the main source of PM2.5. Water-based coatings can greatly reduce VOC emissions. As customers pursue the aesthetic effect of automotive colors, the amount of metallic, pearlescent and other flash paints is rapidly increasing. The preparation of water-based metallic glitter paint with good storage performance, good paint film arrangement effect and fast drying speed is very beneficial to the promotion of water-based car repair. Metallic glitter paint prepared with water-based acrylic resin as the main film-forming material has blue or white light on the side. The color difference between dry and wet films is large, and it is not suitable for color match...
