Abstract

The invention discloses a finish paint for plastics. The finish paint comprises the following components in percentage by weight: 5-10% of aliphatic polyurethane acrylate, 10-15% of aromatic polyurethane acrylate, 0-2% of high polymer containing paint affinity group, 0-0.3% of unsaturated polyamic acid homo-polymer, 0-0.2% of organic silicon, 10-35% of cellulose ester, 2-10% of mixture of pearl powder, aluminum silver powder and paint, 3-5% of nano filler, 10-20% of hydroxy acrylic resin, 5-10% of styrene maleic anhydride modified chloride resin vinegar, 5-10% of poly-functional-group reactive diluent, 2-5% of dual-functional-group reactive diluent, 3-5% of three-functional-group reactive diluent, 1-3% of crack-type photo-initiator, and 0.5-1% of acyl phosphine oxide photo-initiator. The curing time of the finish paint for plastics is only 3min to 4min, so a large amount of power is saved; and the finish consumption of each electric car is respectively reduced by 48% and 53%. With the adoption of the combination of the polyurethane acrylates and the hydroxy acrylic resin, the problem on adhesion among three layers of plastic substrate, finish paint and priming paint is solved.

Description

technical field [0001] The invention relates to coatings, in particular to a topcoat for plastics. Background technique [0002] People's awareness of environmental protection is constantly improving, and environmental protection laws and regulations are gradually promulgated and implemented, and are constantly being improved. This situation forces companies in the manufacturing field to continuously improve production processes to improve the affinity between products and nature. At present, the paint industry is also gradually developing in the direction of water-based and UV (ultraviolet curing) which are environmentally friendly and energy-saving. UV curable coatings are quickly accepted and promoted by the market because of their environmental protection, fast and low energy consumption, and their application range is becoming wider and wider. However, the spray paint used for plastic parts in the motorcycle and electric vehicle industries still has problems such as hi...
