Description

technical field [0001] The invention relates to the field of ultraviolet light curing coatings, in particular to a super wear-resistant ultraviolet light curing coating. Background technique [0002] With the development of the economy and the improvement of people's living standards, the surfaces of building materials, automobiles, marine facilities, and equipment are vulnerable to damage such as impact, scratching, and violent cleaning during use, resulting in loss of aesthetics. Abrasion resistant coating protection. Some materials, especially polymer materials with low hardness, such as PET, PVC and PMMA, have poor surface wear resistance, resulting in a greatly shortened service life, and need to be coated with protective materials on their surfaces to improve their performance. Ultraviolet (UV) curing coating has the advantages of fast curing speed, low production energy consumption, less pollution, and superior coating performance. It has become one of the main prote...
