Abstract

The invention discloses a colored dual-curing UV coating for automobile interior trim parts, and belongs to the field of coating preparation. The invention relates to the colored dual-curing UV coating for the automobile interior trim parts, wherein the colored dual-curing UV coating comprises the following raw materials in parts by weight: 20-30 parts of tetra-functional hydroxyl polyurethane acrylic resin, 16-30 parts of tetra-functional aliphatic polyurethane acrylic resin, 8-12 parts of tri-functional aliphatic polyurethane acrylic resin, 10-15 parts of hexa-functional aliphatic polyurethane acrylic resin, 10-15 parts of a TMPTA monomer, 3-9 parts of an ultraviolet initiator, 0.5-1 part of a leveling agent, 3-5 parts of black pulp, 5-20 parts of ethyl acetate, and 10-20 parts of butylacetate. The shortcomings of two times of spraying and low production efficiency of automobile interior trim parts in the prior art are overcome, the colored dual-curing UV coating has good adhesion force to ABS, PC, ABS+PC and painted plastic substrates. A formed paint film has solvent resistance, water resistance and other properties, can improve a current secondary spraying effect, saves energyand improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of coating preparation, in particular to a colored dual-curing UV coating for automotive interior parts. 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 parts. Ex...
