Water-based acrylic resin and preparation method thereof

The invention provides a water-based acrylic resin and a preparation method thereof, and the preparation method comprises the following steps of: adding a solvent into a container, then adding a P1 component, then adding a P2 component and a heat preservation component into the container, and after heat preservation is finished, conducting stirring, distilling and emulsifying to obtain the water-based acrylic resin. According to the present invention, with the method, the water-based acrylic resin with the characteristics of high solid content and good adhesion can be prepared, the hardness and the impact resistance are high, and the preparation method has characteristics of simple operation, high efficiency, and high practical value. 本发明提供了水性丙烯酸树脂及其制备方法，包括以下步骤：向容器中加入溶剂，然后加入P1组份，再向所述容器中加入P2组份和保温组份，保温结束后，经搅拌、蒸馏和乳化，制得水性丙烯酸树脂。通过本发明方法可制得具有较高固含量和较好附着力的水性丙烯酸树脂，且硬度和抗冲击性能较高，同时，本发明提供的制备方法操作简单、高效，具有较高的实用价值。
