Problems solved by technology

[0004] However, traditional UV-curable coating formulations contain a large amount of low-molecular-weight photosensitizers. Even after curing is complete, there are still a large number of photosensitizer fragments remaining, resulting in poor weather resistance of UV coatings, which are prone to yellowing and peeling off when exposed to sunlight.

Abstract

The invention discloses a weather-resistant UV curing coating which comprises the following components in parts by weight: 20-30 parts of urethane acrylate, 25-35 parts of modified epoxy acrylate, 5-15 parts of a photoinitiator, 1-8 parts of a light stabilizer, 2-7 parts of ethyl acetate, 3-9 parts of glycidol butyl ether, 1-4 parts of an antioxidant and 10-20 parts of filling material. According to prepared the UV curing coating, a layer of tough paint film can be formed on the surface of a base material, and the UV curing coating has strong adhesion force to the base material, is high in surface hardness, and good in scratch resistance, can effectively prevent the base material from being scratched, can be cured and dried quickly, and is environment-friendly, good in weather resistance and applied to the field of exterior wall coating of houses, hospitals, hotels and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a weather-resistant UV curing coating. Background technique [0002] With the increasing awareness of global environmental protection, the coatings industry has also begun to develop in the direction of sustainability. As a result, we can see more and more solvent-free coatings or coating systems using low levels of VOCs. Ultraviolet (UV) curable coatings, as an environmentally friendly coating, are becoming increasingly popular and have experienced rapid growth in recent years. [0003] 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 production. [0004] However, traditional UV-curable coating formulations contain a large amount of low-molecular-weight photosensitizers. Even after curing is complete, there are sti...
