紫外光改性SIS热熔压敏胶研究

Investigation of hot-melt pressure-sensitive adhesive modificated by ultraviolet

研究了紫外光改性苯乙烯-异戊二烯-苯乙烯嵌段共聚物(SIS)热熔压敏胶,探讨了SIS弹性体经紫外照射的交联反应机理,并用红外光谱分析;改性后SIS热熔压敏胶的持粘性、剥离强度和耐热性改善。

Modification of hotmelt pressuresensitive adhesives was researched by ultraviolet. The reaction mechanism of SIS elastomer modification by UV was proposed and discussed. Infrared spectrocopy was applied to identify the proposed reaction mechanism. After radiation holding power, heat resistance and peel strength of SIS hot melt pressure sensitive adhesion are improved.
