摘　　要：聚氯乙烯封边条中树脂含量是决定其力学强度、柔韧性、使用寿命的关键因素。本文采取溶解-沉淀法从聚氯乙烯封边条中提取出树脂,结合红外光谱法鉴别,测定其中树脂含量,无需大型仪器设备,操作简便快捷,结果准确可靠。The content of resin in PVC edge banding is the key factor that determines its mechanical strength,flexibility and service life.In this paper,the dissolution-precipitation method is adopted to extract the resin from the PVC edge banding,and the content of resin is determined combined with the identification using infrared spectroscopy.The operation is simple and fast,and the results are accurate and reliable without using large-scale equipment.

关 键 词：聚氯乙烯封边条 傅里叶变换红外光谱 溶解-沉淀法
