Dry-mixed self-leveling mortar
The invention provides dry-mixed self-leveling mortar and a preparation method thereof. The glass sand in the machine-made sand is fine sand made of waste glass products, resource waste is reduced, the surface of the glass sand is modified and protected, and the glass sand has good workability in mortar. Lithium-based bentonite and sepiolite powder in the surface modifier have certain expansibility, so that the shrinkage rate of the mortar can be reduced. And the modified retarder delays the coagulation time and reduces the shrinkage phenomenon in the coagulation process. In the mortar, the effect of bonding with a base plane is also achieved, and the excellent bonding performance is achieved. A modified leveling agent is added, so that the active ingredients in the mortar are effectively prevented from being flocculated and agglomerated, the mortar can be self-leveled, meanwhile, micro-pores on the surface are sealed, the surface of the mortar is not easily polluted when encountering oil stains, and the anti-pollution capability of the surface of the mortar is improved.
本发明提供了一种干混自流平砂浆及其制备方法。其中，机制砂中的玻璃砂选用废弃的玻璃制品制成细砂，减少资源浪费，同时对玻璃砂表面进行改性保护，使其在砂浆具有良好的和易性。表面改性剂中的锂基膨润土和海泡石粉有一定的膨胀性，可减少砂浆的收缩率。改性缓凝剂延缓凝结时间，同时减少凝固过程中的收缩现象。在砂浆中还起到与基面粘结的作用，具有优异的粘结性能。添加改性流平剂，有效避免砂浆中的有效成分发生絮凝结块现象，使砂浆能够自流平，同时封闭表面的微小孔泡，使砂浆表面在遇到油污时不会轻易的受到污染，增加砂浆表面的抗污能力。
