【摘要】 以丙烯酸为功能性单体 ,采用种子聚合合成了乳胶料表层富集羧基的室温交联核壳复合乳液。着重研究了软硬单体配比、丙烯酸不同的加料方式、壳层乳化剂以及交联剂醋酸锌的用量对乳液性能的影响 ,并取得了丙烯酸加入方式影响核壳乳胶粒表层羧基分布及碱增稠的规律以及生产这类室温交联核壳乳液的优化工艺条件更多还原

【Abstract】 Acrylate core-shell latex with high concentration of carboxyl group on the surface of particles and capable of ionic-crosslinking under room temperature was synthesized by using acrylic acid as functional monomer and use of seed polymerization.The effects of ratio of hard and soft monomers,different feed methods of acrylic acid ,amount of shell emulsifiers and crosslink agent ZnAc 2 on the emulsion properties have been studied.The law that different feed methods of AA affect the distribution of carboxyl group on the surface of core-shell particle and alkalic-thickening nature and the optimum polymerization technology preparing this kind of composite latex have been obtained.更多还原
