Abstract

The invention discloses a special high-performance dual-curable UV coating for automotive interior decorative parts and a preparation method thereof. The special high-performance dual-curable UV coating for automotive interior decorative parts comprises the following raw materials in parts by mass, 2 to 8 parts of a six-functional aliphatic polyurethane acrylic resin; 30 to 50 parts of a four-functional aliphatic polyurethane acrylic resin; 20 to 30 parts of a trifunctional aliphatic polyurethane acrylic resin, 10 to 20 parts of TMPTA monomer, 1 to 5 parts of ultraviolet light initiator 184L,0.5 to 1.5 parts of ultraviolet light initiator TPO, 0.5 to 1.5 parts of BYK-333 type leveling agent, 2 to 8 parts of butyl acetate and 2 to 8 parts of PMA. An existing UV coating formula is optimized, and a coating film prepared from the optimized formula in cooperation with a special curing agent and a diluent has the excellent properties of high hardness, high acid and alkali resistance and high weather resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special high-performance dual-curing UV coating for automotive interior parts and a preparation method thereof. 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. [0003] Traditional automotive interior and exterior coatings are mainly based on PU systems, which have good construction and weather resistance, but at the same time have the disadvantages of slow drying speed and long construction period. UV paint is an environmentally friendly paint, which has the advantages of fast curing speed and high ...
