The invention discloses a gypsum floor mortar leveling agent and a preparation method thereof. The preparation method comprises the following steps: S1, preparing a cementing material, namely weighing Portland cement, drying the Portland cement, adding the Portland cement into mixing equipment, weighing high-alumina cement, adding the high-alumina cement into the mixing equipment, crushing gypsum blocks into gypsum powder by using a crusher, screening the gypsum powder by using a screen scarifier, controlling the particle size of the gypsum powder to be 0.5-0.8 [mu] m, adding the screened gypsum powder into mixing equipment, weighing a certain amount of lime, and adding the lime into the mixing equipment; s2, mixing: electrifying the mixing equipment, and stirring and mixing the Portland cement, the high-alumina cement, the gypsum powder and the lime through stirring blades for 3-6 minutes; s3, blending aggregate and filler: screening the quartz sand and the river sand through the screen scarifier, putting the screened quartz sand and river sand into a drying machine to be dried, then grinding the quartz sand and river sand into powder, and controlling the particle size of the quartz sand powder to range from 3 micrometers to 3.8 micrometers. Compared with other manufacturing technologies, the overall strength of the gypsum-based self-flowing mortar is greatly improved.
本发明公开了一种石膏地坪砂浆流平剂及其制备方法，包括如下步骤：S1、胶结材料制备：称量硅酸盐水泥，将硅酸盐水泥通过烘干后加入混合设备中，称量高铝水泥，加入混合设备中，再将石膏块用粉碎机粉碎为石膏粉，通过清筛机筛分，控制石膏粉粒径在0.5um‑0.8um之间，将筛分后的石膏粉加入混合设备中，称量一定量的石灰加入混合设备中；S2、混合：将混合设备通电，通过搅拌叶片对硅酸盐水泥、高铝水泥、石膏粉与石灰进行搅拌混合，时间为：3‑6min；S3、融入集料与填料：用清筛机筛选石英砂与河沙，将筛选后的石英砂与河沙投入烘干机烘干，再将石英砂与河沙研磨成粉状，控制石英砂粉粒径在3um‑3.8um之间。与其它制作技术相比，大大提高了石膏基自流砂浆的整体强度。
