| 摘 要： | 以多元醇(PPG-2000或PTMG-2000)、甲苯二异氰酸酯(TDI)为主要原料,合成了PU(聚氨酯)预聚体;然后加入E-44型EP(环氧树脂)和缩水甘油醚(Glycidyl)对PU预聚体进行封端,制成E/G-PU(端环氧基PU);再加入TDE-85型EP和活性稀释剂,制备出环保无溶剂型E/G-PU/TDE-85/活性稀释剂胶粘剂;最后采用间苯二甲胺(m-XDA)固化剂和2,4,6-三(二甲胺基甲基)苯酚(DMP-30).促进剂对该EP胶粘剂进行固化,明显提升了体系的固化速率。结果表明:当w(活性稀释剂D-085)=5%时,E/G-PU(PTMG-2000)/TDE-85/D-085胶粘剂的剪切强度(24.63 MPa)相对最大。

| Abstract: | With polyol(PPG-2000 or PTMG-2000),toluene diisocyanate(TDI) as main raw materials,a PU(polyurethane) prepolymer was prepared.Then with E-44 type EP(epoxy resin) and glycidyl as terminated agents of PU prepolymer,an E/G-PU(epoxy-terminated PU) was made.Whereafter,an environment-friendly solvent-free adhesive based on E/G-PU/TDE-85/reactive diluent was made by adding TDE-85 type EP and reactive diluent.Finally,the EP adhesive,which was cured by curing agent(m-XDA) and accelerant(DMP-30), could obviously enhance curing speed.The results showed that the E/G-PU(PTMG-2000)/TDE-85/reactive diluent(D-085) had reversely maximum shear strength(24.63 MPa) when mass fraction of D-085 was 5%. |
