Polymer modified aluminate cement-based facing mortar and preparation method thereof
The invention relates to polymer modified aluminate cement-based facing mortar and a preparation method thereof. The preparation method comprises the steps of: mixing aluminate cement, heavy calcium carbonate powder, gypsum, sand, pigment, cellulose ether and a defoaming agent according to the proportion to obtain a dry component, and mixing a polymer emulsion and water to obtain a wet component; and stirring and mixing the dry component and the wet component for 3-5 minutes to obtain the facing mortar. Compared with the prior art, aluminate cement instead of traditional Portland cement is used as a main cementing material of the facing mortar, so that the generation of a saltpetering source Ca (OH) 2 is fundamentally avoided; a silane modified emulsion can form a three-dimensional latticed film layer in the hardening process of the facing mortar and attached to the surface of a hydration product, cross-linking and overlapping effects are provided, and a hydrophobic effect is achieved; and migration of the soluble salt is reduced, a strong inhibition effect is achieved on the saltpetering of the facing mortar, and the facing mortar has the characteristics of no cracking, no hollowing, water resistance, gas permeation, bright color and the like, and is highly decorative.
本发明涉及一种聚合物改性铝酸盐水泥基饰面砂浆及其制备方法，制备方法包括依照配比将铝酸盐水泥、重钙粉、石膏、砂、颜料、纤维素醚、消泡剂混合，得到干组分，将聚合物乳液、水混合，得到湿组分；之后将干组分与湿组分搅拌混合3‑5min，即得到上述饰面砂浆。与现有技术相比，本发明以铝酸盐水泥取缔传统硅酸盐水泥作为饰面砂浆的主要胶凝材料，从根本上避免了泛碱源头Ca(OH)2的产生，并且硅烷改性乳液在饰面砂浆硬化过程中会形成三维网格状的膜层附着在水化产物表面，既起到交联搭接的作用又具有疏水效果，进而减少了可溶性盐的迁移，对饰面砂浆泛碱具有较强的抑制效果，同时还具有不开裂、不空鼓、防水、透气和色彩亮丽等特点，非常具有装饰性。
