Silicon-containing polyacrylate flatting agent and preparation method thereof

The invention relates to a silicon-containing polyacrylate flatting agent and a preparation method thereof. The preparation process of the prepared silicon-containing polyacrylate flatting agent mainly comprises the following steps that firstly, acrylic ester oligomer containing double bonds is synthesized, and then, under the action of a catalyst, the acrylic ester oligomer containing the double bonds and silicon-containing hydrogenated silicon oil are subjected to an addition reaction so that the polyacrylate flatting agent can be obtained. The prepared silicon-containing polyacrylate flatting agent has good surface control ability, does not stabilize foam, can be recoated and has good shrinkage cavity resistance and base material wettability. 本发明涉及种含硅的聚丙烯酸酯流平剂及其制备方法。本发明制备的含硅的聚丙烯酸酯流平剂，其制备过程主要包括如下步骤：先合成含双键的丙烯酸酯低聚物，再在催化剂的作用下，与含硅的氢化硅油通过加成反应得到聚丙烯酸酯流平剂。本发明制备的含硅聚丙烯酸酯流平剂具有较好的表面控制能力，不稳泡，可以重涂，具有良好的抗缩孔和基材润湿性。
