The invention discloses building gypsum based on industrial solid waste desulfurized gypsum as a raw material and a preparation method thereof. The building gypsum based on industrial solid waste desulfurized gypsum as a raw material comprises the following raw materials in parts by weight: 120-160 parts of desulfurized gypsum, 30-45 parts of microporous ceramic, 40-60 parts of vitrified micro bubbles, 20-35 parts of expanded perlite, 5-8 parts of coconut shell powder, 3-8 parts of cement, 1-3 parts of sodium carboxymethyl cellulose, 0.3-0.35 parts of a retarder, 0.2-0.4 parts of hydroxymethylcellulose, 0.2-0.4 parts of polypropylene fiber and 0.2-0.5 parts of a composite early strength agent. The raw materials are environment-friendly material, desulfurized lime, microporous ceramic, sodium carboxymethyl cellulose, coconut shell powder and the like are compounded for use, the obtained building gypsum is proper in viscosity, high in grain size gradation and good in water-retaining property and has an energy storage function, the problem that an obtained building gypsum product is easy to fall off after use due to high content of water in desulfurized gypsum in subsequent utilization and treatment is solved, and the building gypsum has a wide market prospect.
本发明公开了一种基于工业固废脱硫石膏为原料的建筑石膏及其制备方法，基于工业固废脱硫石膏为原料的建筑石膏包括重量份计的原料：脱硫石膏120～160份、微孔陶瓷30～45份、玻化微珠40～60份、膨胀珍珠岩20～35份、椰壳粉5～8份、水泥3～8份、竣甲基纤维素1～3份、缓凝剂0.3～0.35份、羟甲基纤维素0.2～0.4份、聚丙烯纤维0.2～0.4份、复合早强剂0.2～0.5份。本发明用料环保，通过脱硫石灰、微孔陶瓷、竣甲基纤维素、椰壳粉等进行复配使用，得到的建筑石膏胶黏性适当，粒径级配高，保水性好，还具有储能功能，解决了脱硫石膏在后续利用处理中含水量大，得到的建筑石膏产品使用后易脱落的问题，具有广阔的市场前景。
