摘要：以高级脂肪醇聚氧乙烯醚(OE-6)、甲苯二异氰酸酯(TDI)为原料,物料比n(TDI)∶n(OE-6)=1.05∶1、温度45℃、反应2.5h合成了端异氰酸酯预聚体,再将其与多元胺按照摩尔比n(多元胺)∶n(预聚体)=1.2∶1、温度40℃、反应3h扩链,得到油脂基聚氨酯改性脂肪胺水性环氧固化剂(UFAWECAOF)。用红外光谱、13C-NMR表征了UFAWECAOF的结构。粒径分析表明目标产物具有乳化液体环氧树脂的功能,其与环氧树脂EPON828复配制备的双组分水性涂料涂膜固化物,柔韧性达1mm、铅笔硬度达3H、耐冲击性达50kg/cm。
A series of novel urethane-modified fatty amine used as waterborne epoxy curing agents based on oil and fat were prepared from polyamines and isocyanate group-terminated prepolymer synthesized from fatty alcohol polyoxyethylene ether （OE-6） and toluene diisocyanate （TDI）.The optimum reaction conditions ofprepolymer were as follows： the mixture of TDI and OE-6 in molar ratio 1.05 ： 1, at 45 ℃ for 2.5 h. The condition of polyamines extending chains were as follows： the mixture of polyamine and oligomers in molar ratio 1.2 ： 1, reaction temperature 40 ℃. After 3 h most of solvent was removed from the adduct, distilled water was continuously added to the adduct at 50 -60 ℃ until solids content becomes 50%-55%, then urethane-modified fatty amine was synthesized. The structure of the product was characterized by FT-IR and ^13C-NMR. The particle size analysis suggested that it could emulsify liquid epoxy resin. The properties of the two-component film of the urethane-modified fatty amine and liquid epoxy resin were measured, with flexibility lmm, pencil hardness 3H, impact resistance 50 kg/cm.
