摘要： 将自制的高分子乳化剂与烷基溴化铵季铵盐型乳化剂配合使用，制备阳离子丙烯酸酯乳液，确定了高分子乳化剂与十六烷基三甲基溴化铵（CTAB）的最佳质量配比为 19.6:0.6，由此得到的乳液粒径最小、稳定性最佳。 并探讨了添加不同功能性单体对阳离子乳液的耐水性与粒径的影响，实验结果表明：加入功能单体三甘醇二甲基丙烯酸酯交联剂（V-389）时乳液的耐水性最好，当 V-389 用量为 1.7%（占主单体量）时，乳液的吸水率达到最小值 3.62%，性能较优良。

Abstract: A cationic acrylate emulsion was synthesized by synergizing the self-prepared polymer emulsifier with the alkyl quaternary ammonium emulsifier. It was proved that the minimum particle size of the emulsion having good storage stability was obtained when the mass ratio of polymer emulsifier to hexadecyl trimethyl ammonium bromid (CTAB) was 19. 6: 0.6. Meanwhile, the influence of different functional monomers on the water resistance and particle size of the polymer emulsion was studied The result showed that the cationic emulsion gave the best water resistance when the functional monomer V-389 was added, and specifically gave the lowest water absorption 3. 62% and good property when the dosage of v-389 was 1.7%( based on total weight of main monomers ).
