Abstract

The invention discloses a preparation method of a colored double-curing UV coating, and belongs to the field of coating preparation. The preparation method comprises the steps: (1) mixing quaternary hydroxy polyurethane acrylate resin, quaternary aliphatic polyurethane acrylate resin, ternary aliphatic polyurethane acrylate resin, hexahydric aliphatic polyurethane acrylate resin and TMPTA monomerso as to obtain a mixture A; (2) adding an ultraviolet light initiator to butyl acetate so as to obtain a mixture B; (3) adding the mixture B to the mixture A, and adding a leveling agent so as to obtain a mixture C; (4) adding black slurry to the mixture C, and performing stirring so as to obtain a mixture D; and (5) adding ethyl acetate and butyl acetate to the mixture D, and performing uniformstirring and filtration so as to obtain the coating. The shortcoming of low production efficiency caused by twice spraying needed by automobile interior parts in the prior art is overcome, the formedpaint film has the properties of solvent resistance, water resistance and the like, the current twice spraying effect can be improved, and energy saving and improvement of the production efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of coating preparation, and more specifically, relates to a preparation method of colored dual-curing UV coating. Background technique [0002] Nowadays, 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 environmental protection coatings. type paint. UV paint is an environmentally friendly coating, which has the advantages of fast curing speed and high work efficiency. Therefore, the research and development of UV varnish series paint for automotive interiors is in line with market trends. The application of UV varnish series paints for automotive interiors has great potential in the application of automotive interior p...
