摘要
为提高涂料印花中织物摩擦牢度,减少黏合剂等助剂的使用,以苯乙烯、丙烯酸丁酯为单体用微乳液聚合法对颜料蓝15∶1进行表面包覆改性,探讨了表面活性剂用量、单体用量等对所制备的超细颜料平均粒径、粒径分布和分散稳定性的影响,用扫描探针显微镜观察了改性颜料的形貌。结果表明:随着单体用量的增加,颜料的平均粒径先增大后减少;颜料分散时表面活性剂的用量影响体系的分散稳定性及颜料的平均粒径;表面改性后的超细颜料在无黏合剂存在的情况下,对纯棉织物的摩擦牢度有一定的改善。
C. I. Pigment Blue 15：1 was encapsuled by miniemulsion polymerization with styrene and butyl acrylate for the purpose of improving the rubbing fastness and reducing the use of auxiliaries such as binders. The effects of the amount of surfactants and monomers on the average particle sizes, PDI, stability of the system were investigated. The morphologies of the ultrafine particles were observed by the scanning probe microscope. The results indicated that the average particle size of the pigment first increases and then decreases as the amount of the monomers increases; the amount of surfactant affects the average particle sizes and the stability of the system; the rubbing fastnesses of the modified pigment for pure cotton fabric is rather good with absence of binders.
