Environment-friendly gypsum-based self-leveling powder and preparation method thereof
The invention discloses environment-friendly gypsum-based self-leveling powder and a preparation method thereof, and belongs to the technical field of self-leveling powder. Comprising the following raw materials in parts by weight: 85-90 parts of beta-semi-hydrated gypsum, 5 parts of Portland cement, 2-3 parts of fly ash, 3 parts of mineral powder, 2-3 parts of modified silica fume powder, 0.05 part of hydroxypropyl methyl cellulose, 0.01-0.02 part of a polyether defoaming agent, 0.3-0.4 part of a modified water reducing agent, 0.02 part of a retarder, 0.08-0.1 part of sodium gluconate and 1-1.5 parts of redispersible latex powder. The raw materials of the prepared gypsum-based self-leveling powder are environment-friendly and pollution-free, the dosage of each raw material is reasonably configured, and the dosage of the additive is reduced, so that the prepared environment-friendly gypsum-based self-leveling powder not only is low in cost, but also has excellent effects of high fluidity, high strength and smooth surface, and has a wide market prospect.
本发明公开了一种环保型石膏基自流平粉料及其制备方法，属于自流平粉料技术领域，包括以下重量份原料：β‑半水石膏85‑90份、硅酸盐水泥5份、粉煤灰2‑3份、矿粉3份、改性硅灰粉2‑3份、羟丙基甲基纤维素0.05份、聚醚消泡剂0.01‑0.02份、改性减水剂0.3‑0.4份、缓凝剂0.02份、葡萄糖酸钠0.08‑0.1份、可再分散乳胶粉1‑1.5份；本发明制得的石膏基自流平粉料的原料环保无污染，合理配置各原料的用量并减少外加剂的用量，使制得的环保型石膏基自流平粉料不仅成本低，而且还具有流动度高、强度高和表面光滑的优异效果，具有广阔的市场前景。
