Defoaming agent applied to thin-layer self-leveling mortar and preparation method of defoaming agent
The invention provides a defoaming agent applied to thin-layer self-leveling mortar and a preparation method of the defoaming agent. The defoaming agent comprises the components: white carbon black, polyether, fatty alcohol and alkynol silicon polyether. The preparation method comprises the steps: (1) firstly, mixing and stirring fatty alcohol and part of white carbon black to form a dispersoid M1; (2) preparing alkynol silicon polyether, then adding the dispersoid M1 and polyether, and mixing to obtain a dispersoid M2; and (3) slowly spraying the dispersoid M2 onto A2 through a metering pumpunder certain temperature and rotating speed conditions, and mixing to obtain M3; and finally, screening the M3 to obtain the solid defoaming agent. The solid defoamer prepared by the method is specially used for solving the problems of surface cracking and hollowing of thin-layer self-leveling mortar, and compared with a traditional defoaming agent, the defoaming agent disclosed by the inventionhas the advantages of simple preparation method, good defoaming and foam inhibition performances, no influence on the stability of a self-leveling mortar system and capability of remarkably improvingthe surface performance of the self-leveling mortar.
本发明提供了一种应用于薄层自流平砂浆的消泡剂及其制备方法，该消泡剂的组分包括白炭黑、聚醚、脂肪醇、炔醇硅聚醚；制备方法为（1）首先将脂肪醇和部分白炭黑混合搅拌形成分散体M1；（2）制备炔醇硅聚醚，然后加入分散体M1和聚醚混合后得到分散体M2；（3）在一定的温度和转速条件下，将分散体M2通过计量泵缓慢喷洒到A2上，混合后得到M3；最后将M3经过筛分得到固体消泡剂。本法制备的固体消泡剂专用于解决薄层自流平砂浆表面开裂，空鼓的问题，本发明的消泡剂对比传统消泡剂具有制备方法简单，同时具有消泡、抑泡性能好，不影响自流平砂浆体系的稳定性，可以显著改善自流平砂浆的表面性能。
