本发明属于乳液技术领域。本发明提供了一种室温自交联阳离子聚合物乳液，由包含如下质量份的原料制备得到：丙烯酸酯类单体40~100份；卤化氮正阳离子单体2~10份；含卤素的乙烯基单体1~5份；有机硅氧烷单体1~5份；引发剂0.2~1份；乳化剂1~5份；水60~150份；浓盐酸0.01~0.05份；1，6-己二胺0.5~2份。本发明还提供了一种室温自交联阳离子聚合物乳液的制备方法以及包含该乳液的水性涂料。本发明的室温自交联阳离子聚合物乳液的粒径小，凝胶率低，钙离子稳定性、机械稳定性和放置稳定性良好；水性涂料的漆膜硬度高，耐水白性、耐碱性能和耐75%的乙醇水溶液擦拭性能优异。

The invention belongs to the technical field of lotion. The invention provides a room temperature self crosslinking cationic polymer lotion, which is prepared from raw materials containing 40~100 parts of acrylate monomer; 2-10 parts of halide nitrogen cation monomer; 1-5 parts of vinyl monomers containing halogen; 1-5 parts of organosiloxane monomer; 0.2-1 parts of initiator; 1-5 parts of emulsifier; 60-150 parts of water; 0.01-0.05 parts of concentrated hydrochloric acid; 0.5-2 parts of 1,6-hexanediamine. The invention also provides a preparation method of room temperature self crosslinking cationic polymer lotion and a water-based paint containing the lotion. The room temperature self crosslinking cationic polymer lotion has small particle size, low gel rate, good calcium ion stability, mechanical stability and placement stability; The paint film of water-based coatings has high hardness, excellent water whiteness resistance, alkali resistance, and resistance to wiping with 75% ethanol aqueous solution.
