摘　　要：制备了一种含N-乙烯基咔唑(NVA)的耐高温丙烯酸酯压敏胶(PSA),同时讨论了NVA对压敏胶黏度、吸水率、接触角、粘接性和耐高温性能的影响。研究结果表明:当m(NVA)=7.5%(相对于单体总质量而言),改性后的PSA经过165℃、4 h高温处理后剥离无残胶,其耐热性优于未改性的PSA(110℃,1 h),而且改性后的压敏胶最大180°剥离强度可达9.7 N/25 mm,是未改性的两倍。A high temperature resistance acrylate pressure sensitive adhesive(PSA) containing N-vinyl carbazole(NVA)was prepared. The effects of NVA on viscosity,water absorption,contact angle,adhesion and high temperature resistance of PSA were discussed. The research results showed that when m(NVA)=7.5%(relative to the total mass of monomer),the modified PSA was peeled off without residual adhesive after high temperature treatment at 165 ℃ for 4 h,and its heat resistance was better than that of the unmodified PSA(110 ℃,1 h). And the maximum 180° peel strength of modified PSA could reach 9.7 N/25 mm,which was twice that of the unmodified.
