耐电解质增稠剂的优化

The Optimization for the Electrolyte-resistant Thickener

以丙烯酸和自制丙烯类单体ZXDW为原料,以Span-80为乳化剂,以过硫酸铵-亚硫酸氢钠为引发剂,以N,N-亚甲基双丙烯酰胺(NMBA)为交联剂,采用反相乳液共聚合成制备了耐电解质增稠剂,通过五因素四水平正交实验详细研究了引发剂用量、单体的比例、单体的浓度、单体的中和度和交联剂的用量对所制备的增稠剂的粘度和耐电解质性能的影响,考察了以白油为油相的实验效果,确定了耐电解质增稠剂的最佳制备工艺条件。

The electrolyte-resistant thickener was prepared by inverse emulsion polymerization using acrylic acid and ZXDW as monomers, Span-80 as emulsifier, ammonium persulfate-sodium bisulfate as initiator, and N,N-methylenebisacrylamide（NMBA） as crosslinker. The influences of initiator, the ratio of monomers, the concentration of monomers, the degree of neutralization, and crosslinker on the thickening ability and electrolyte resistance were studied particularly by orthogonal design. In addition, the influence of the white oil on the results was researched. According to the results, the better conditions to take out the reaction was researched.
