纯丙乳液聚合及应用研究

摘要

Polyacrylate emulsion was synthesized using seed emulsion polymerization method.The effects of reaction time, temperature and emulsifier dosage on the emulsion polymerization were investigated.The optimal synthesis process was obtained: emulsifer dosage was 0.77％ (based on emulsion mass), m(OP-10):m(LAS)=2:1, dropped at 80 ℃ for 60 min,held at 80 ℃ for 45 min.The emulsion was applied in fabric pigment printing,and crosslinking monomer was selected.The influences of curing time and temperature on printing effect were discussed. The optimal application process was obtained: TM -200 2.897 O％ (owm), cured at 130 ℃ for 180 s.The crocking fastness and washing fastness of fabric treated under the optimal process were good.%采用种子乳液聚合法合成了丙烯酸酯乳液,研究了反应时间、反应温度、乳化剂用量等因素对纯丙乳液聚合的影响;优化合成工艺为:乳化剂[m(OP-10):m(LAS)=2∶1]用量0.77%(对乳液质量),80℃滴加60 min,保温45 min.将该纯丙乳液应用于织物的涂料印花中,筛选了交联单体,讨论了焙烘时间、焙烘温度等对织物印花效果的影响,优选出最佳应用工艺:TM-200用量2.897 0%(对单体总质量),130℃焙烘180 s.在此工艺下处理的织物耐摩擦牢度、耐洗色牢度均较好.
