Novel gypsum surface layer self-leveling material
The invention discloses a novel gypsum surface layer self-leveling material which is prepared from the following raw materials in parts: early strength ordinary Portland cement, quartz sand, anhydrite, low-viscosity hydroxypropyl methyl cellulose, a defoaming agent, water, high-alumina cement, ground calcium carbonate, redispersible latex powder, a water reducing agent and tartaric acid, wherein the proportion of the early strength ordinary Portland cement is 25%-40%, the proportion of the quartz sand is 5%-10%, and the proportion of the anhydrite is 4%-9%. According to the novel gypsum surface layer self-leveling material disclosed by the invention, the slurry can have ideal fluidity at a relatively low water cement ratio, and can be automatically unfolded and leveled only by virtue of the gravity of the slurry without external force, so that a flat mirror-like surface is obtained. By using the novel gypsum surface layer self-leveling material manufactured according to proportion, it is guaranteed that hollowing and cracking phenomena caused by different materials are avoided between different working procedures in the using process, and the construction technology is simple.
本发明公开了一种新型的石膏面层自流平材料，包括以下份额的原材料：早强型普通硅酸盐水泥、石英砂、硬石膏、低粘度羟丙基甲基纤维素、消泡剂、水、高铝水泥、重质碳酸钙、可再分散乳胶粉、减水剂、酒石酸，所述早强型普通硅酸盐水泥的份额为25％‑40％，所述石英砂的份额为5％‑10％，所述硬石膏的份额为4％‑9％。本发明所述的一种新型的石膏面层自流平材料，浆体在较低的水灰比下也能拥有理想的流动度，无需外力而仅靠浆体自身重力就可自动展开流平，从而获得平整如镜的表面，通过使用此配比制造而成的新型石膏面层自流平材料，保证了在使用时不同工序之间不会因为材质不同而产生空鼓、开裂现象，且施工工艺简单。
