低残余单体含量的丙烯酸酯混拼乳液的制备方法
摘要：
低残余单体含量的丙烯酸酯混拼乳液的制备方法，它涉及丙烯酸酯混拼乳液的制备方法。它的制备工艺为：通过复合使用水溶性偶氮类引发剂和氧化还原引发剂体系后聚合处理丙烯酸酯乳液的方法去除残余单体；使用乳液混拼的技术将使用一般聚合方法制得的丙烯酸酯乳液混拼，也就是将不同玻璃化温度的软硬乳液按一定比例混拼，得到至少用乃至不用成膜助剂也可室温成膜且综合性能良好的乳液。它有效除去乳液溶剂及聚合物颗粒两相中所含残余单体以达到净味的效果；使乳液可少用乃至不用成膜助剂也能室温成膜且综合性能良好。
摘要（英）：

The invention relates to a preparation method for an acrylate blended emulsion with low residual monomer content, which comprises the following processes of: removing residual monomers by a method which uses a water-soluble azo initiator and a redox initiator composite system for post-polymerization treatment of an acrylate emulsion; and using an emulsion blending technique to blend the acrylate emulsion obtained by using general methods, namely blending hard and soft emulsions with different glass transition temperature according to a certain ratio to obtain an emulsion capable of forming a film at room temperature by at least using or even without using a film-forming auxiliary agent and with good overall performance. The preparation method effectively removes the residual monomers in the solvent and the polymer particles of the emulsion to achieve an odor removal effect; and the emulsion can form the film at room temperature by at least using or even without using the film-forming auxiliary agent and has good overall performance.
