Core-shell type polymer emulsion as well as preparation method and application thereof

The invention provides a core-shell type polymer emulsion as well as a preparation method and application thereof. The core-shell type polymer emulsion is prepared from the following raw materials: polybutadiene, an emulsifier, a cross-linking agent, an initiator, a grafting monomer and a shell layer monomer, according to the invention, the polybutadiene is directly used as a preparation raw material of a core in the core-shell polymer emulsion, so that a high-pressure reaction kettle is not needed when the core-shell polymer emulsion is prepared, and the core-shell polymer emulsion has the advantages of low preparation requirement and simple operation process, and also has the advantage of uniform and stable particle size of emulsion particles; the method is more suitable for industrial application. 本发明提供一种核壳型聚合物乳液及其制备方法和应用，所述核壳型聚合物乳液的制备原料包括聚丁二烯、乳化剂、交联剂、引发剂、接枝单体和壳层单体；本发明直接采用聚丁二烯作为核壳型聚合物乳液中核心的制备原料，进而在制备核壳型聚合物乳液时无需使用高压反应釜，使得所述核壳型聚合物乳液具有制备要求低以及操作工艺简单的优势，且还具有乳胶粒粒径均一稳定的优势，更加适合工业化应用。
