摘　　要：将PP/HDPE用马来酸酐(MAH)进行熔融接枝改性制得PP-R铝塑复合管用热熔胶树脂,红外光谱分析证实MAH确已接枝到树脂上。当HDPE比例占40％,MAH接枝率0.7％时,树脂与铝箔和PP-R有最大的剥离强度。在该树脂中添加10％的增粘树脂、40％的粘度调节剂后,获得了剥离强度达135 N/cm的热熔胶。Hot melt adhesive resin for PP-R/aluminum composite pipe was prepared by grafting PP/HDPE with maleic anhydride; the resin was characterized by FTIR spectrum. The resin has maximum peeling strength in the case of 40% HDPE and grafting MAH=0. 7%. When this resin is mixed with 10% tackifier and 40% viscosity modifier, a hot melt adhesive is gained, with 135N/cm peeling strength.
