The invention provides an anhydrous gypsum self-leveling material and a preparation method thereof. The self-leveling material comprises the following components in parts by weight: 6500-9000 parts of II type anhydrous gypsum; 500 to 1500 parts of cement; 500 to 2000 parts of mineral powder or fly ash; 5-20 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 cement and the mineral powder or the fly ash are used as auxiliary materials, the water reducing agent, the defoaming agent and the water-retaining thickening agent are added, all the components interact, the mineral powder or the fly ash has a good excitation effect, metal salt excitants do not need to be added, and the problem that the excitants and the water reducing agent conflict does not exist; therefore, the cement has the characteristics of high flowability, high strength and high hydration performance, and has excellent performance; the II-type anhydrite takes ardealite as a raw material, the source is wide, and resource utilization of the ardealite is facilitated.
本发明提供了一种无水石膏自流平材料及其制备方法，所述自流平材料按重量份计包括以下组分：Ⅱ型无水石膏6500～9000份；水泥500～1500份；矿粉或粉煤灰500～2000份；减水剂5～20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，辅以水泥以及矿粉或粉煤灰，再通过减水剂、消泡剂及保水增稠剂的添加，各组分相互作用，矿粉或粉煤灰具有较好的激发作用，无需添加金属盐类激发剂，不存在激发剂和减水剂冲突的问题，使其具备流动性高、强度高、水化性能高的特点，性能优异；所述Ⅱ型无水石膏以磷石膏为原料，来源广泛，有助于实现磷石膏的资源化利用。
