Abstract

The invention relates to a high-chemicals resistance inner decoration high-luster black paint and a preparation method thereof. The paint is composed of a two-component system of aqueous acrylic resinand isocyanate resin, and is obtained by crosslinking and solidification through baking at the temperature of 70-80 DEG C; wherein the paint comprises a component A of 65-75 parts of self-synthesis aqueous acrylic resin, 0.1-0.5 parts of a levelling agent, 0.1-0.5 parts of an antifoaming agent, 1-3 parts of triethylamine, 1-4 parts of dimethyl ethanolamine, 10-20 parts of water, and 8 parts of 30% of non-resin aqueous black color paste; and the paint comprises a component B of 80-90 parts of the aqueous isocyanate resin, and 10-20 parts of propylene glycol methyl ether acetate. Compared withthe prior art, the preparation method is simple, water dilution performance is strong, appearance of a paint film is excellent, and the high-chemicals resistance inner decoration high-luster black paint has the advantages of high hand sweat resistance, sunscreen cream resistance, good manifestness, high hardness, and good weatherability.

Description

Technical field [0001] The invention relates to the technical field of automotive coatings, in particular to a high-chemical-resistant interior high-gloss black paint and a preparation method thereof. Background technique [0002] The coating protection and decoration of automotive interior parts have high chemical resistance requirements in the automotive industry. For example, people sitting in the car’s hands, sweat, summer sunscreen, winter hand cream, will touch the interior parts Causes a destructive change in the coating. Nowadays, people pay more attention to the chemical resistance of the coatings on the parts of automobile interior parts that people can touch. With the improvement of people's awareness of environmental protection and the improvement of environmental protection laws and regulations, the application of water-based coatings in automotive interior parts has received great attention. [0003] For example, the patent CN101928482A discloses a water-soluble low...
