以环氧丙烯酸酯树脂、环氧树脂(EP)、自由基光引发剂和阳离子光引发剂为主要原料,制备混杂UV(紫外光)固化胶粘剂,并且采用响应面法对混杂UV固化胶粘剂的配方进行优化;以预聚体配比、光引发剂配比作为自变量,以混杂UV固化胶粘剂在玻璃上的附着力作为因变量,采用Design Expert软件对2个自变量进行多次拟合,建立相应的数学模型和3维曲面,得到最优的混杂UV固化胶粘剂配方并进行验证。研究结果表明:二项式是描述因变量和自变量之间关系的最佳模型,当环氧丙烯酸酯树脂/EP质量比为1.19、自由基光引发剂/阳离子光引发剂质量比为1.00时,制成的混杂UV固化胶粘剂在玻璃基材上的附着力(9级)相对最强。
Epoxy acrylate resin, epoxy resin (EP), free radical photoinitiator and cationic photoinitiator were used as main raw materials to prepare hybrid UV (UV) cured adhesives. The response surface methodology The optimal ratio of prepolymer and photoinitiator was used as independent variable to determine the adhesion of hybrid UV-curable adhesive to glass as the dependent variable. Design Expert software was used to fit the two independent variables multiple times to establish Corresponding mathematical model and 3-D curved surface, get the best mixed UV curing adhesive formulation and verify. The results show that binomial is the best model for describing the relationship between dependent variable and independent variable. When epoxy acrylate resin / EP mass ratio is 1.19 and mass ratio of radical photoinitiator / cationic photoinitiator is 1.00 , Made of hybrid UV curing adhesive on the glass substrate adhesion (9) is relatively the strongest.
