The invention discloses an anti-fog UV coating for an automobile exterior trim lamp part, a preparation method thereof, and a paint film formed by the anti-fog UV coating. The anti-fog UV coating forthe vehicle lamp comprises the following raw materials in parts by weight: 9-functionality aliphatic polyurethane acrylic resin, 4-functionality aliphatic polyurethane acrylic resin, 6-functionality organic silicon modified polyurethane acrylic resin, 2-functionality aliphatic polyurethane acrylic resin, an ultraviolet initiator 184, an ultraviolet initiator TPO, a flatting agent, an anti-doodlingaid, ethyl acetate and butyl acetate. The anti-fog UV coating provided by the invention can obviously improve the problem of aerial fog residue on a car lamp and improve the self-cleaning property ofthe surface of a paint film, and can completely meet the VW TL221 standard by Volkswagen.
Description
technical field [0001] The invention belongs to the technical field of paint preparation, and in particular relates to an anti-fog UV paint for automobile exterior decoration parts and lamps, a preparation method thereof and a paint film formed by the paint film. Background technique [0002] With the enhancement of people's awareness of environmental protection and the development of polymer science, the demand for the use of environmentally friendly coatings is also increasing. In order to find a competitive advantage, domestic companies are gradually tightening the indicators of VOC content in coatings, developing and applying environmentally friendly coatings. coating. UV paint is an environmentally friendly paint, which has the advantages of fast curing speed and high work efficiency. Therefore, the research and development of UV series paint for automotive interior and exterior decoration is in line with the market trend. The application of UV series paint for automoti...
