摘要
首先研究了高分子阳离子乳化剂的合成,其中以苯乙烯(St)和丙烯酰胺(AM)为主单体,十六烷基三甲基溴化铵(CTAB)为相转移乳化助剂,环氧氯丙烷(ECH)、三甲胺为季铵化试剂。最终确定当CTAB用量为1g,AM用量为5g,ECH用量为5.2g时,所得到的乳化剂的乳化性能最优良。对不同功能性单体对阳离子乳液涂膜吸水率与粒径的影响做了研究,结果表明:当加入交联体系双丙酮丙烯酰胺-己二酰肼基丙烯酸酯(DAAM-ADH)为1.0g时,吸水率达到最低值5.39%。最后通过加入三氧化二铝分散液制得核壳结构乳液,结果表明:当加入三氧化二铝分散液20g时,所得到的乳液包裹性能最好,乳液较稳定。
With taking St and AM as main monomers, CTAB as phase transfer emulsifying agent, epoxy chloropropane, trimethylamine as quaternary ammonium reagent, a self-made polymer emulsifier was synthesized. The emulsifier is more stable comprising CTAB lg, AM 5g and ECH 5.2g. The article also investigated the influences of different functional monomers on the polymer emulsion water resistance and particle size. The results showed： the cationic emulsion comprising DAAM-ADH 1.0g had the best water resistance. Finally, a core shell emulsion was made by adding nano-sturcuted alumina transparent dispersion, and we know that the emulsion prepared by dispersion 20 g gave a better state and stability.
