UV hardening liquid as well as preparation method and application thereof

The invention discloses UV hardening liquid as well as a preparation method and application thereof. The UV hardening liquid is prepared from the following raw materials in percentage by mass: 30 to 45 percent of high-functionality polyurethane acrylate, 15 to 20 percent of low-functionality polyurethane acrylate, 2 to 5 percent of short-wavelength photoinitiator, 0.05 to 0.3 percent of long-wavelength photoinitiator, 0.5 to 2 percent of organic silicon additive, 10 to 20 percent of slow-drying solvent and 10 to 40 percent of quick-drying solvent. The hardening liquid is high in hardness, good in steel wool resistance, good in adhesive force, excellent in water boiling resistance, not prone to cracking after high-pressure forming, good in appearance and capable of well meeting the market requirements. 本发明公开了一种UV加硬液及其制备方法与应用，其原料及各原料的质量百分数为：高官能度聚氨酯丙烯酸酯30-45％，低官能度聚氨酯丙烯酸酯15-20％，短波长光引发剂2-5％，长波长光引发剂0.05-0.3％，有机硅助剂0.5-2％，慢干类溶剂10-20％，快干类溶剂10-40％。本发明加硬液硬度高、耐钢丝绒好、附着力好、有优异的耐水煮性能、高压成型不易开裂、外观良好，可以很好的满足市场的需求。
