Abstract

The invention discloses a preparation method of a novel water-based automobile surface lacquer. The novel water-based automobile surface lacquer adopts purified water as a solvent and two-component waterborne polyurethane as a bonding material, and is added with a graphene filler, so that through the cooperation of reasonable component ratio and the filler, the prepared water-based automobile surface lacquer not only is friendly to environment, but also further promotes the improvement of a thermal property, a mechanical property and a hydrophobic performance. The surface lacquer is rich in water-based resin, so that the dosage of a toxic nonpolar reagent is reduced, the emission of VOC (Volatile Organic Compounds) is effectively controlled, the adhesive force is high, the surface lacquer is safe and environmentally-friendly, the hardness of a film is high, the weather fastness, the heat resistance and the hydrophobic property of the whole surface lacquer are greatly improved, and the surface lacquer has excellent performances of ultraviolet resistance, acid rain resistance, wear resistance, scratch resistance and the like. The film is bright-colored, clear, attractive and elegant.

Description

technical field [0001] The invention relates to the technical field of automobile painting, in particular to an environment-friendly water-based automobile topcoat specially used for automobiles. Background technique [0002] With the improvement of aesthetics and environmental awareness, people have higher and higher requirements for automotive paint. However, most of the automotive coatings on the market are solvent-based. Due to the high total volatile organic solvent (VOC), the pollution to the environment is relatively large, and the recycling is limited, resulting in waste of resources and serious harm to people's health. healthy. Therefore, the country has successively introduced laws and regulations on VOC emissions, and various chemical, automobile manufacturing and research institutions are constantly promoting environmentally friendly water-based coatings that use water as a solvent. The "water-based" coating is of great significance. [0003] Among the VOC emis...
