摘　　要：本文从压敏胶结构与性能的关系出发,总结了高端压敏胶的设计思路。基于活性乳液聚合技术,设计并制备出了可满足高端胶带要求的丙烯酸酯嵌段共聚物乳液,突破现有水性压敏胶性能不均衡、不耐湿热的困境,期待其能加速高端压敏胶的“油改水”进程。Starting from the relationship between the structure and performance of pressure sensitive adhesive,the design ideas of high-end pressure sensitive adhesive were summarized in this paper.Based on active emulsion polymerization technology,the acrylate block copolymer emulsion was designed and prepared that could meet the requirements of high-end adhesive tape,breaking through the current dilemma of unbalanced performance and poor resistance to moisture and heat in waterborne pressure sensitive adhesive,which is expected to accelerate the process of"oil to water"in high-end pressure sensitive adhesive.
