摘 要: 以已二酸,已二醇,1,2-丙二醇,甲苯二异氰酸酯(TDI)和三羟基甲基丙烷(TMP)为原料,合成了一种双组分聚氨酯胶粘剂。制备了一种新型固化剂(TMP-TDI聚合物),甲组分为端羟基型的预聚体,选取的PEPA与TDI的摩尔比为8∶1,乙组分(TDI-TMP加成物),TDI与TMP最佳摩尔比控制在3.0~3.1左右。 Two-component polyurethane adhesive was prepared by adipic acid,hexylene glycol,propylene glycol,TDI and TMP.A hardening agent-(TMP-TDI),component B was synthesized and component A was the end hydroxyl type prepolymer.The mole ratio of PEPA and TDI was 8∶1,the optimal mole ratio of TDI and TMP for component B was about 3.0-3.1.
