【摘要】 采用紫外光(UV)本体聚合的方法,将光引发剂在UV LED光源激发分解下引发多种丙烯酸酯类单体聚合制备压敏胶。考察了光照强度与距离的关系以及不同单体的聚合反应速率,进而确定了软硬单体最佳配比以及压敏胶最佳反应时间,并且将UV本体聚合制备的压敏胶与加热本体聚合的压敏胶进行了对比。结果显示,当丙烯酸(AA)作为硬单体、软硬单体配比为90:10(质量比)、单体质量为30g、反应时间为20s时,压敏胶有最佳的综合性能。更多还原

【Abstract】 The pressure sensitive adhesive was prepared by polymerization of a variety of acrylate monomers with the excitation decomposition of photoinitiator under UV LED light.The relationship between the hght intensity and distance as well as the polymerization rate of different monomers were investigated.The best ratio of soft to hard monomer and the best reaction time of the prepolymer were determined.The pressure sensitive adhesive prepared by UV bulk polymerization was compared with that by bulk polymerization.The results showed that the pressure sensitive adhesive had the best comprehensive performance when AA was used as the hard monomer,the weight ratio of soft to hard monomer was 90:10,and the reaction time was 20 s for 30 g monomers.The pressure sensitive adhesive prepared by UV bulk polymerization is superior to that by heating bulk polymerization in both the performance and the production.更多还原
