摘要
用全反射红外技术对聚氯乙烯薄膜及其胶带进行了增塑剂迁移性能研究。增塑剂迁移经一定时间后达到平衡，测出聚氯乙烯薄膜中增塑剂迁移的扩散系数约为０１ｎｍ２／ｍｉｎ。实验证明：影响其增塑剂迁移性能的因素是催化剂的类型、用量及胶粘剂的种类。
The migration of plasticizer in PVC film and adhesive tape was measured by total reflection IR spectrometry. The migration was in equilibrium in a period of time. The diffusivity of the plasticizer is 0.1nm 2·min -1 for the PVC film. The factors affecting the migration are the amounts, sorts of catalysts and the type of tapes for the PVC tape with the different formula.
