反相乳液聚合法合成聚丙烯酸盐增稠剂的研究

范文编号:SW036  范文字数:13031,页数:28

摘要：本文以研制开发适合于活性染料印花用的增稠剂为目标，介绍了以丙烯酸、丙烯酰胺、200号汽油、N，N-亚甲基双丙烯酰胺、过硫酸钾、乳化剂等为原料制备聚丙烯酸增稠剂的工艺。
 采用反相乳液聚合法，将水溶性单体溶于水相，借助乳化剂和搅拌作用，将其分散于非极性有机液体中，形成油包水型(W/O型)乳液，进而聚合成涂料印花增稠剂。
 实验发现不加大单体的增稠剂的耐电解质性比较差。通过马来酸酐和脂肪醇聚氧乙烯醚合成大单体，引入到增稠剂分子中，可以使产品的耐电解质性得到明显地改善。

Study on Inverse Emulsion Polymerization of Polyacrylate thickener

Abstract: This text regards developing and is suitable for the thickener that the reactive dye print stamp as the goal, having introduced with acrylic acid , AM , No. 200 gasoline , N, N- pair of propylene acyl amine of methyl crafts preparing the thickener for raw materials .
 Thickener for pigment printing was prepared by inverse emulsion polymerization with water-based monomers dispersing in non·polar organic solvent aided with agitation and emulsifier to form W/O(water-in-oil)emulsion.
 It is found that the electrolyte sexual tolerance of the thickener is bad without adding the macromer unto the thickener. The electrolyte sexual tolerance of the thickener can be improved apparently by the introduction of macromer synthesized by maleic anhydride and fatty alcohol polyoxyethylene.
Keywords:  Inverse emulsion polymerization; Polyacrylate thickener; Thickening property; Viscosity; Anti-electrolytic property
