一种可剥型压敏胶的化学结构和表面形貌表征

Analysis and Characterization of a removable Pressure Sensitive Adhesive

对一种不损坏任何被粘表面的可剥型压敏胶的化学结构进行了分析：使用不同溶剂分步抽提样品，测得各样品的红外光谱，还直接对胶粘剂表面进行了光声光谱的测定。使用扫描电子显微镜做了胶粘剂表面和断面的观察。从上述结果对低粘压敏胶的特性做了分析。

The chemical composition of a removable pressure sensitive adhesive has been analyzed by FTIR and optoacoustic spectroscopy. The results show that the essential ingredients contain the linear liphatic polyesters and unsaturated Polyesters. The SEM observations show that the adhesive layer is of spherical particles, which increase both the surface area and the elasticity of the adhesive.
