Special gypsum-based self-leveling mortar for PVC (polyvinyl chloride) floor glue construction
The invention belongs to the technical field of building materials, and particularly discloses special gypsum-based self-leveling mortar for PVC (polyvinyl chloride) floor glue construction, which comprises water and powder, and the powder comprises the following components in percentage by mass: 35-50% of alpha semi-hydrated gypsum, 30-40% of fine sand, 20-30% of ground calcium carbonate, 3-7% of cement, 0.01-0.08% of modified amino acid gypsum retarder and 0.01-0.08% of propyl hydroxy methyl cellulose ether. 0.08%-0.15% of a defoaming agent, 0.5%-1.5% of redispersible latex powder and 0.15%-0.20% of a water reducing agent; the mass ratio of the water to the powder is (0.23-0.30): 1. The gypsum-based self-leveling mortar disclosed by the invention has better flowability and surface hardness, can improve the construction efficiency and the flatness of the building ground, and is particularly suitable for leveling construction before pasting PVC floor glue.
本发明属于建筑材料技术领域，具体公开一种用于PVC地板胶施工的专用石膏基自流平砂浆，包括水和粉料：粉料包括按质量百分比计的以下组份：α半水石膏35‑50%，细砂30‑40%，重质碳酸钙20‑30%，水泥3‑7%，改性氨基酸类石膏缓凝剂0.01‑0.08%，丙羟基甲基纤维素醚0.01‑0.08%，消泡剂0.08‑0.15%，可再分散型乳胶粉0.5‑1.5%，减水剂0.15‑0.20%；水与粉料的质量比为0.23‑0.30∶1。本发明的石膏基自流平砂浆具有较好的流动性和表面硬度，能够提高建筑地面施工效率和建筑地面的平整度，特别适合于粘贴PVC地板胶前的找平施工。
