Composite gypsum self-leveling ground system leveling material and preparation method thereof
The invention provides a composite gypsum self-leveling ground system leveling material and a preparation method thereof, and relates to the technical field of building materials. The self-leveling structure specifically comprises a foaming gypsum self-leveling cushion layer on the bottom layer and a gypsum self-leveling surface layer on the surface layer. The volume ratio of the foaming gypsum self-leveling cushion layer to the gypsum self-leveling surface layer is 1: (0.5-2). Wherein the foaming gypsum self-leveling cushion layer is prepared from the following components in parts by weight: 1000 parts of gypsum powder, 1 to 2 parts of a water-retaining thickening agent, 1.5 to 2.5 parts of a water reducing agent, 1 to 1.5 parts of an air entraining agent and 1 to 1.5 parts of a retarder. The gypsum self-leveling surface layer is prepared from the following components in parts by weight: 1000 parts of gypsum powder, 0.6 to 1.2 parts of a water-retaining thickening agent, 2 to 4 parts of a water reducing agent, 1 to 2 parts of a defoaming agent and 1 to 1.5 parts of a retarder. Compared with traditional gravel-free paste self-leveling, the foaming gypsum self-leveling cushion layer has the advantages that the material consumption per square meter can be reduced by 30-50%, and the construction cost is more economical. And the cementing materials are all gypsum solid wastes, and other aggregates or fine fillers are not added, so that the material is green, environment-friendly and low in cost.
本发明提供了一种复合石膏自流平地面系统找平材料及其制备方法，涉及建筑材料技术领域。具体包括底层的发泡石膏自流平垫层和表层的石膏自流平面层；所述发泡石膏自流平垫层和石膏自流平面层的体积比为1：(0.5‑2)。其中，所述发泡石膏自流平垫层按重量份数计，包括以下组分：石膏粉1000份、保水增稠剂1‑2份、减水剂1.5‑2.5份、引气剂1‑1.5份、缓凝剂1‑1.5份。所述石膏自流平面层按重量份数计，包括以下组分：石膏粉1000份、保水增稠剂0.6‑1.2份、减水剂2‑4份、消泡剂1‑2份、缓凝剂1‑1.5份。本发明与传统无砂石膏自流平相比，发泡石膏自流平垫层单位平米可降低30‑50％的材料用量，使工程造价更加经济。且胶凝材料全部为石膏固废，不添加其他骨料或者细填料，绿色环保、成本低廉。
