Low-odor emulsion, preparation method and application

The invention discloses a low-odor emulsion as well as a preparation method and application thereof. The emulsion is prepared from the following monomer components in percentage by mass through emulsion polymerization: a, 35-70wt% of ethyl acrylate; b, 1.3 to 10wt% of an olefinic unsaturated monomer containing an acetoacetate functional group; c, 0.5 to 5 weight percent of unsaturated hydrophilic monomer; d, 0.2 to 5 percent of a reaction type silane coupling agent; e, 10%-40% of dodecadecyl (methyl) acrylate to tetradecyl (methyl) acrylate; and f, 10-40% of other olefinic unsaturated monomers. Under the condition of not adding a coalescing agent and an anti-freezing agent, the emulsion for the latex paint, which is ultralow in odor and excellent in scrubbing resistance and freeze-thaw stability, is prepared. 本发明公开了一种低气味乳液、制备方法及应用，所述乳液由包括以下质量百分比的单体组分通过乳液聚合制备得到：a、35-70wt％的丙烯酸乙酯；b、1.3-10wt％的含有乙酰乙酸酯官能团的烯属不饱和单体；c、0.5-5wt％的不饱和亲水单体；d、0.2-5％的反应型硅烷偶联剂；e、10-40％的十二至十四烷基的(甲基)丙烯酸酯；f、10-40％的其它烯属不饱和单体。本发明在不添加成膜助剂及抗冻剂的情况下，制
