Ultraviolet curing coating and preparation method thereof

The invention provides an ultraviolet curing coating and a preparation method thereof, and the ultraviolet curing coating comprises the following raw materials in percentage by mass: 10-20% of high-functionality polyurethane acrylate, 5-10% of low-functionality polyurethane acrylate, 25-35% of low-viscosity polyester acrylate, 15-20% of polyfunctionality modified acrylate monomer, 5-10% of amine modified polyether acrylate, 12-15% of matting powder, 2-5% of wear-resistant powder, 3-6% of a photoinitiator, 0.1-0.5% of a leveling agent, 0.1-1% of a defoaming agent and 1-5% of a dispersing agent. The ultraviolet curing coating has the main advantages that the solid content of the paint is close to 100%, and a cured film is good in odor removal effect, high in hardness and excellent in wear resistance, has the characteristic of low gloss, and is applied to the field of PVC floor coating. 本发明提供一种紫外光固化涂料及其制备方法，其组分由以下质量百分数的原料组成：高官能度聚氨酯丙烯酸酯10～20％，低官能度聚氨酯丙烯酸酯5～10％，低粘度聚酯丙烯酸酯25～35％，多官能度改性丙烯酸酯单体15～20％，胺改性聚醚丙烯酸酯5～10％，消光粉1
