摘要：以甲苯2,4-二异氰酸酯(TDI)、高级脂肪醇聚氧乙烯醚(AEO-6)、四乙烯五胺、丙烯腈为原料合成了油脂基聚氨酯改性脂肪胺水性环氧固化剂(CA-B)。将CA-B分别与水性环氧乳液AB-EP-20、AB-EP-44、AB-EP-51组成固化体系,经分析可知,水性体系CA-B/AB-EP-44性能最优。通过差示扫描量热法、涂膜力学性能测试,研究了n(环氧基)∶n(胺氢)对CA-B/AB-EP-44体系固化物性能的影响,结果表明,n(环氧基)∶n(胺氢)为1.1∶1(摩尔比)时涂膜的综合性能最佳,此时漆膜柔韧性达1 mm、铅笔硬度达2 H、附着力达1级、耐冲击性≥60 kg.cm、乙醇渗透量(%(24 h))为15.3,与参比样Ⅰ、参比样Ⅱ(市售)固化物的物理性能相当。
Waterborne epoxy curing agent of urethane-modified fatty amine based on oil and fat（CA-B）was synthesized from fatty alcohol polyoxyethylene ether（AEO-6）,toluene diisocyanate（TDI）,tetraethylenepentamine and acrylonitrile.Complexed CA-B consist with waterborne epoxy latex AB-EP-20,AB-EP-44 and AB-EP-51 respectively.It is understandable after analysis that the overall properties of the curable system CA-B/AB-EP-44 are best.The effects of the molar ratio of epoxy group and amine hydrogen on the properties of the cured film for CA-B/ABEP-44 system were investigated by means of differential scanning calorimetry method and the mechanical properties.The results indicate that the optimum properties are as follows flexibility 1 mm,pencil hardness 2 H,adhesion 1,impact resistance ≥60 kg·cm,alcohol infiltration capacity 15.3%（24 h）,when the molar ratio of epoxy group to amine hydrogen is 1.1∶1.Under the conditions,the mechanical properties of the curing system has reached the level of the domestic commercial products of contrast sampleⅠand contrast sampleⅡ.
