Gypsum self-leveling mortar and preparation method thereof
The invention discloses gypsum self-leveling mortar and a preparation method thereof, and aims to solve the problem of poor waterproofness of the existing thermal insulation gypsum mortar. According to the key point of the technical scheme, the building block is prepared from the following raw materials in parts by weight: 100-150 parts of a modified polyurethane/diatomite composite material, 100-120 parts of desulfurized gypsum, 20-40 parts of a mineral admixture, 15-30 parts of Portland cement, 2-5 parts of a water reducing agent, 5-10 parts of fine sand, 7-12 parts of EVA rubber powder, 1-3 parts of a gypsum retarder, 12-20 parts of hollow glass beads, 50-70 parts of water, 4-6 parts of auxiliary material resin, 5-8 parts of steel slag and 0.5-0.8 part of quaternary ammonium salt. 0.2 to 0.5 part of nano barium sulfate, 0.1 to 0.3 part of nano copper oxide and 3 to 5 parts of steel fiber. The components of the mortar are optimized, the auxiliary material resin polyolefin elastomer is added, the addition amount is controlled, the moisture resistance of the mortar is improved, the defects that hollowing and cracking are prone to occurring are overcome, the leveling property is good, heat preservation and water resistance are achieved, the weight is relatively small, and construction is facilitated.
本发明公开了一种石膏自流平砂浆及其制备方法，旨在解决现有的保温石膏砂浆防水性差的问题。其技术方案要点是：包括以下重量份的原料：改性聚氨酯/硅藻土复合材料100‑150份、脱硫石膏100‑120份、矿物掺合料20‑40份、硅酸盐水泥15‑30份、减水剂2‑5份、细砂5‑10份、EVA胶粉7‑12份、石膏缓凝剂1‑3份、空心玻璃微珠12‑20份和水50‑70份、辅料树脂4‑6份、钢渣5‑8份、季铵盐0.5‑0.8份、纳米硫酸钡0.2‑0.5份、纳米氧化铜0.1‑0.3份、钢纤维3‑5份。本发明通过对砂浆的成分进行优化，增加辅料树脂聚烯烃弹性体，并控制添加量，提高砂浆的耐潮性能，克服容易出现空鼓、开裂的缺陷，流平性好，保温防水，重量也相对较小，利于施工。
