摘　　要：针对目前涂料染色黏合剂存在柔软性差、色牢度低及乳化剂含烷基酚聚氧乙烯醚等缺陷,采用预乳化半连续种子乳液聚合方法,以丙烯酸酯类单体、甲基丙烯酸缩水甘油酯为主要原料,十二烷基硫酸钠和异构醇聚氧乙烯醚(E-1310)为复合乳化剂,合成一种涂料染色聚丙烯酸酯乳液,并对其合成工艺进行优化。通过力学性能、粒径、Zeta电位及乳液稳定性能的检测对正交试验设计制备的乳液进行表征,并且对染色织物的柔软性和色牢度进行评价。通过红外光谱、差示扫描量热仪对优化工艺合成的涂料进行检测。结果表明:硬段质量为8 g,甲基丙烯酸缩水甘油酯质量为2 g,丙烯酸羟乙酯质量为2 g,复合乳化剂占4%时,染色织物的柔软性较好,干摩擦牢度达到5级,湿摩擦牢度达到4级,乳液性能稳定,涂膜的玻璃化转变温度为-27℃。To overcome the defects of existing coating dyeing binders on poor softness,low soaping and crocking fastness,and alkylphenol ethoxylates contained in emulsifier,tacoating dyeing polyacrylate emulsion was synthesized from the main materials of acrylate monomers and glycidyl methacrylate by the pre-emulsification and seeded semi-continuous emulsion polymerization method using a composite emulsifier of sodium dodecyl sulfate and isomeric alcohol polyoxyethylene ether（E-1310）,and the synthesis process was optimized.The emulsions prepared in orthogonal experiments were studied by performance tests of the mechanical properties,particle size,Zeta potential and emulsion stability.The color fastness and softness of the dyed fabrics based on polyacrylate emulsions were tested.Meanwhile,the optimized emulsions were further detected by infrared spectroscopy and differential scanning calorimetry.The results show that the emulsion performance is stable,the grass transition temperature of the polyacrylate film is-27 ℃ and the dyed fabrics is softness with the dry friction up to grade 5 and wet friction up to grade 4,when the content of hard monomers is 8 g,glycidyl methacrylate 2 g,hydroxyethyl acrylate 2 g and composite emulsifier 4%.
