Matte finishing clear coat and preparation method thereof

The invention relates to matte finishing clear coat and a preparation method thereof. The matte finishing clear coat is made from the following materials according to percent by weight: 25-65% of core-shell acrylic copolymer emulsion, 0.05-6% of a thickener, 0.1-5% of a rheological aid, 0.1-0.6% of a dispersant, 0.1-0.6% of a wetting agent, 1.5-2% of a film-forming aid, 0.5-5% of a wax emulsion, 0.1-0.5% of a defoaming agent, 1.5-7.0% of a functional aid, and 20-65% of water. The matte finishing clear coat is still good in matte effect even no matting agent is added, storage stability of a system is good, a coat film has good transparency and water white resistance, and the matte finishing clear coat has excellent comprehensive performance. 本发明涉及种哑光罩光清面漆及其制备方法。该哑光罩光清面漆包括如下重量百分比计原料：核壳结构丙烯酸类共聚物乳液25?65％、增稠剂0.05?6％、流变助剂0.1?5％、分散剂0.1?0.6％、润湿剂0.1?0.6％、成膜助剂1.5?2％、蜡乳液0.5?5％、消泡剂0.1?0.5％、功能助剂1.5?7.0％、水20?65％。所述哑光罩光清面漆，在不加入消光剂的情况下仍具有良好的哑光效果，同时体系的储存稳定性良好，漆膜的透明性及耐水白性好，综合性能优越。
