摘　　要：本文以聚氨酯丙烯酸酯(UV-7605)和环氧树脂(EP815)作为预聚体,丙烯酸作为增粘树脂,二甲基丙烯酸酯作为稀释剂,羟基环己基苯酮作为光引发剂,制备了性能优异的无溶剂辐射固化型丙烯酸压敏胶。通过对丙烯酸压敏胶的成膜性、固化时间、初粘力、粘结强度、附着力和耐老化性能测试,研究讨论了预聚体、增粘树脂、单体稀释剂、光引发剂等对其性能的影响。结果得出,各组分含量为:UV-7605∶EP815为1∶2,丙烯酸:3%;光引发剂:3.5%,辐射固化时间为60s时,可制得成膜性好,初粘力高,附着力和耐老化性优良的辐射固化型丙烯酸压敏胶。In this paper,polyurethane acrylate(UV-7605)and epoxy were used as prepolymer,acrylic acid as tackifying resin,dimethyl acrylate as diluent and hydroxycyclohexyl phenyl ketone as photoinitiator,a solvent-free radiation curing acrylic pressure sensitive adhesive with excellent properties was prepared.The film-forming property,curing time,initial adhesion,adhesion strength,adhesion and aging resistance of acrylic pressure sensitive adhesive were tested,the effects of prepolymer,tackifying resin,monomer diluent and photoinitiator on their properties were discussed.The results showed that the content of each component was 1∶2 for UV-7605∶EP815,3%for acrylic acid,3.5%for photoinitiator and 60s for radiation curing time,the radiation curing acrylic pressure sensitive adhesive with good film formation,high initial adhesion,excellent adhesion and aging resistance could be prepared.
