摘要: 以茶油皂脚脂肪酸甲酯制备的水溶性改性胺(CA-921)与水性环氧树脂固化,通过热重分析、差示扫描量热法(DSC)、机械性能测试及扫描电镜分析,研究了环氧树脂分散相粒子的粒径和黏度、环氧基与胺氢物质的量之比及固化温度对固化物性能的影响。研究结果表明,黏度及粒径均较小的水性环氧乳液AB-EP-20与固化剂CA-921复配所得漆膜热稳定性较佳;水性环氧体系AB-EP-20/CA-921在环氧基与胺氢物质的量之比为1.1∶1、室温下固化 3 h 后 60 ℃ 固化 3 h 的条件下,固化物的综合性能最佳,此时漆膜的柔韧性为 1 mm、铅笔硬度 2 H、附着力1级、耐冲击性≥50 kg·cm、耐水性(25 ℃)≥7 d、耐醇性≥30 d。

Abstract: The effects of the diameter and viscosity of epoxy resin dispersion, the molar ratio of epoxy group to amino hydrogen and the curing temperature on the properties of the cured water soluble modified amine from fatty acid methyl esters of tea oil soapstock were investigated by thermal gravimetric analysis (TGA), differential scanning calorimetry (DSC), mechanical pro-perty test and scanning electron microscopy (SEM). It was shown from the results that the thermal stability of the cured film from the water-soluble modified amine CA-921 and the epoxy emulsion AB-EP-20 with smaller particle size and lower viscosity was better. When the water-soluble modified amine CA-921 cured with the epoxy emulsion AB-EP-20 in molar ratio of epoxy group to amine hydrogen 1.1∶1 at room temperature for 3 h and then 60 ℃ for 3 h, the cured film exhibited the optimum properties with flexibility 1 mm, pencil hardness 2 H, adhesion 1, impact resistance ≥50 kg·cm, water-resistance(25 ℃)≥7 d and alcohol-resistance ≥30 d respectively.
