The invention provides an anhydrous gypsum self-leveling material and a preparation method and application thereof. The self-leveling material comprises the following components in parts by weight: 4000-6000 parts of II type anhydrous gypsum; 2000-3000 parts of an admixture; 2000-3000 parts of aggregate; 3-50 parts of a water reducing agent; 5-20 parts of a defoaming agent; and 3-15 parts of a water retention thickening agent. According to the self-leveling material, the II-type anhydrous gypsum is used as a main material, the admixture and the aggregate are used as auxiliary materials, the hydration and coagulation rate of the anhydrous gypsum is adjusted, the strength is improved, the water reducing agent, the defoaming agent, the water-retaining thickening agent and other components are added, and all the components are matched with one another to achieve a synergistic effect, the material has the characteristics of short setting time, high flowability, high strength, good volume stability, good water resistance and excellent performance; the II-type anhydrite takes ardealite as a raw material, is wide in source and low in cost, facilitates resource utilization of the ardealite, and avoids pollution of the ardealite to the environment.
本发明提供了一种无水石膏自流平材料及其制备方法和用途，所述自流平材料按重量份计包括以下组分：Ⅱ型无水石膏4000～6000份；掺合料2000～3000份；集料2000～3000份；减水剂3～50份；消泡剂5～20份；保水增稠剂3～15份。本发明所述自流平材料以Ⅱ型无水石膏为主料，辅以掺合料和集料，调节无水石膏的水化、凝结速率，提高强度，再通过减水剂、消泡剂及保水增稠剂等组分的添加，各组分相互配合，发挥协同作用，使其具备凝结时间短、流动性高、强度高、体积稳定性好、耐水性好的特点，性能优异；所述Ⅱ型无水石膏以磷石膏为原料，来源广泛，成本低，有助于实现磷石膏的资源化利用，避免磷石膏对环境的污染。
