Abstract

The invention relates to the field of coatings, in particular to an anti-aging UV curing coating. The anti-aging UV curing coating comprises the following raw materials in parts by weight: 35-45 parts of polyurethane acrylate, 10-15 parts of grapheme, 3-6 parts of bamboo carbon fiber, 25-30 parts of hydrobisphenol-A epoxy resin, 3-5 parts of a photoinitiator, 3-8 parts of an anti-aging agent, 7-12 parts of a reactive diluent, 0.3-0.6 part of a leveling agent, 0.2-0.5 part of an anti-settling agent and 1-1.5 parts of a foam breaking agent. The anti-aging UV curing coating is excellent in aging resistance, can ensure long-term effectiveness after being used, and has the characteristics of good corrosion resistance, excellent crack resistance and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an aging-resistant ultraviolet curing coating. Background technique [0002] UV-curable coatings have anti-pollution and energy-saving effects, excellent chemical and physical properties of coating, and fast curing characteristics, and are widely used in many fields. Widely used in the production of plastics, vacuum plating, PVC flooring, shadow mask boards, car headlights, wooden floors, cabinet panels, etc. UV as a new processing technology has been commercialized in Australia for more than 25 years, and the market continues to be optimistic. The technology is developing steadily at an annual rate of nearly 10%, especially in surface coatings and related industries. UV light-curing coatings have the advantages of no volatile organic compounds (VOC), less environmental pollution, fast curing speed, energy saving, good performance of cured products, and suitable for high-speed automatic...
