摘　　要：按正交实验的方法,采用自制的聚氨酯改性丙烯酸酯齐聚物(PUA)与改性剂,研制出了紫外光(UV)快速固化胶粘剂,并对其影响因素进行了简要分析。结果表明,由PUA改性的UV固化胶粘剂具有较好的粘接性能。在所考察的影响因素中,对胶粘剂强度的影响程度大小顺序为:自制改性剂>1,6-己二醇二丙烯酸酯(HDDA)/三羟甲基丙烷三丙烯酸酯(TPGDA)>聚酯丙烯酸酯(EB-524)/PUA齐聚物≈多官能度单体>单官能度单体=KH570>光引发剂。Using orthogonal experiment method, a series of the high-strength and fast ultraviolet （UV） curable adhesives were prepared from modifier and acrylic oligomer which was modified by polyurethane （PUA）. The results showed that the polyester polyacrylate UV curable adhesives had good bonding capacity. The influence factors of raw materials on the adhesive strength decreased gradually in the following order： modifier, HDDA, TPGDA, EB-524/PUA oligomers, polyfunctional monomer, monofunctional monomer, KH570 and light irradiator.
