High-performance facing mortar and preparation method thereof
The invention belongs to the technical field of building materials, and provides high-performance facing mortar and a preparation method thereof. The high-performance facing mortar is prepared from white Portland cement, sulphoaluminate cement, superfine gypsum powder, calcium sulfate whiskers, superfine slag powder, high-activity metakaolin, modified styrene-acrylic emulsion, terpene emulsion, anair entraining agent, an antifoaming agent, a wetting agent, a water repellent, a leveling agent, an inorganic pigment and quartz sand. The preparation method comprises the following steps: mixing white Portland cement, sulphoaluminate cement, ultrafine gypsum powder, calcium sulfate whiskers, superfine slag powder and high-activity metakaolin, then adding other raw materials, conducting mixing,adding water accounting for 20-25% of the total weight of the high-performance facing mortar, and conducting uniform stirring before usage. The high-performance facing mortar provided by the inventionhas good physical and mechanical properties and decorative properties; in particular, the frosting problem of the facing mortar is practically solved, the facing mortar is endowed with excellent stain resistance, and the high-performance facing mortar can meet the use requirements for adjustable setting time and operable time and improves construction efficiency.
本发明属于建筑材料技术领域，提供了一种高性能饰面砂浆及其制备方法，高性能饰面砂浆由白色硅酸盐水泥、硫铝酸盐水泥、超细石膏粉、硫酸钙晶须、矿渣微粉、高活性偏高岭土、改性苯丙乳液、萜烯乳液、引气剂、消泡剂、润湿剂、憎水剂、流平剂、无机颜料以及石英砂组成，制备时先将白色硅酸盐水泥、硫铝酸盐水泥、超细石膏粉、硫酸钙晶须、矿渣微粉、高活性偏高岭土混合，再加入其它原料混合，使用时加入高性能饰面砂浆总重量20％‑25％的水，搅拌均匀后使用。本发明产品具有良好的物理力学性能和装饰性能，尤其是切实解决了饰面砂浆的泛霜问题，并赋予其优良的耐沾污性能，还能满足凝结时间和可操作时间可调的使用要求，提高施工效率。
