摘要
采用种子乳液聚合的方法将功能单体乙酰乙酸基甲基丙烯酸乙酯(AAEM)引入丙烯酸树脂大分子链中,添加胺基聚醚(简称胺醚)作为交联剂,制得可室温自交联的丙烯酸树脂复合乳液。通过FT-IR测试,证实了AAEM和胺醚之间交联反应的发生。以乳液的最低成膜温度、粒径及分散系数以及涂膜的吸水率、耐溶剂性、抗张强度和断裂伸长率为考察指标,探讨了AAEM-胺醚交联体系及其用量对乳液及涂膜基本性能的影响。结果表明:随着AAEM-胺醚交联体系用量的增加,最低成膜温度从15.8℃降到13℃,表现为更易成膜;涂膜24 h平衡吸水性增强,吸水率从42.9%升高到52.4%,这种交联体系所形成的三维网络结构可使涂膜具有优异的机械性能及耐溶剂性。
The functional monomer methylacrylic acid(AAEM) was introduced into the macro-molecular chains of anionic acrylic resin prepared by seed emulsion polymerization method.Via adding crosslinking agent amino polyether,briefly named amine ether,an self-crosslinking acrylic resin composite emulsion was produced.The crosslinking reaction between AAEM and amine ether was confirmed by the FT-IR test.Based on emulsion particle size,the dispersion coefficient,the minimum film-forming temperature and coating of water absorption and solvent resistance,tensile strength and elongation at break as examining indexes,discussed the effection of AAEM-amine ether crosslinked system of on the basic performance of this composite emulsion and its film.These results showed that the stability of acrylic resin composite emulsion increased after adding amine ether in it,the minimum film-forming temperature decreased from15.8 ℃ to 13 ℃,performanced for easier to film-forming,24 h balance water absorption rate of the coating increased from 42.9%to 52.4%,the three dimensional crosslinking network structure made the coating has more excellent mechanical properties and solvent resistance.
