摘　　要：以丙烯酸-2-乙基己酯(2-EHA)、甲基丙烯酸(MAA)为软、硬单体,丙烯酸-2-羟基乙酯(HEA)、丙烯酰胺(AM)为官能团单体,2-羟基-2-甲基-1-苯基丙酮为光引发剂,己二醇二丙烯酸酯(HDDA)为交联剂,采用紫外光交联聚合固化,聚合方法为本体聚合制备丙烯酸酯UV光固化压敏胶(PSA)。主要研究内容包括:软、硬单体之间的配比对压敏胶性能的影响,官能团单体的种类及用量对压敏胶性能的影响,光引发剂、交联剂的用量分别对压敏胶性能的影响以及UV光照时间对压敏胶性能的影响等。研究结果发现,当2-EHA与MAA之间的配比为6:4,官能团单体HEA和AM用量分别为10%、1.5%,光引发剂2-羟基-2-甲基-1-苯基丙酮、交联剂HDDA的用量分别为2%、1.5%,UV光照时间为120s时压敏胶的综合性能较好。Acrylic-2-ethylhexyl ester(2-EHA),methacrylic acid(MAA)as soft and hard monomers,acrylic-2-hydroxyethyl ester(HEA)and acrylamide(AM)as functional group monomers,2-hydroxy-2-methyl-1-phenylacetone as photoinitiator,and hexylene diacrylate(HDDA)is a cross-linking agent,which is cured by ultraviolet optical cross-linking polymerization.The polymerization method is to prepare acrylic acid UV light curing pressure sensitive adhesive(PSA)for body polymerization.The main research contents include:the influence of the ratio between soft and hard monomers on the performance of pressure-sensitive glue,the influence of the type and dosage of functional group monomer on the performance of pressure-sensitive glue,the influence of the amount of light initiator and crosslinking agent on the performance of pressure-sensitive glue,and the influence of UV lighting time on the performance of pressure-sensitive glue.The research results found that when the ratio between 2-EHA and MAA is 6:4,the dosage of functional group monomer HEA and AM is 10%and 1.5%respectively,and the dosage of photoinitiator 2-hydroxy-2-methyl-1-phenylacetone and crosslinking agent HDDA is 2%and 1.5%respectively,UV lighting time The comprehensive performance of pressure-sensitive adhesive at 120s is good.
