Gypsum-based wall leveling material as well as preparation method and use method thereof
The invention relates to a gypsum-based wall leveling material as well as a preparation method and a use method thereof. The wall leveling material is prepared from the following raw materials in parts by mass: 55-70 parts of semi-hydrated gypsum; 8-20 parts of fly ash; 4-8 parts of an admixture; 4-8 parts of calcium hydroxide; 3-6 parts of zeolite; 0.2-0.5 part of a water retaining agent; and 0.05-0.1 part of a retarder; wherein the admixture is selected from one or two of silica fume or metakaolin. The gypsum-based wall leveling material provided by the invention does not need cement, redispersible rubber powder and a water repellent, can also have good water resistance, can maintain good mechanical properties in a high-humidity environment, can also solve the problems of hollowing and cracking of a wall surface, and is low in cost and easier to apply and popularize.
本发明涉及一种石膏基墙体找平材料及其制备方法和使用方法。以质量份计，其制备原料包括：半水石膏55份‑70份；粉煤灰8份‑20份；掺合料4份‑8份；氢氧化钙4份‑8份；沸石3份‑6份；保水剂0.2份‑0.5份；缓凝剂0.05份‑0.1份；所述掺合料选自硅灰或偏高岭土中的一种或两种。本发明所述的石膏基墙体找平材料非必须使用水泥、可再分散性胶粉和憎水剂，也可以具有较好的耐水性能，在高湿度环境下，可以保持良好的力学性能，同时，可以解决墙面空鼓、开裂难题，并且成本低，更易应用推广。
