紫外光本体聚合制备丙烯酸酯压敏胶
Preparation of acrylate pressure sensitive adhesive by UV bulk
polymerization
摘要
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 light 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 thermal stability of the pressure sensitive adhesives before and after crosslinking was characterized. 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 ratio of soft to hard monomer was 90:10,and the reaction time was 20s for 30g 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.关键词
