The invention discloses self-leveling gypsum. The self-leveling gypsum is prepared from the following raw materials in parts by weight: 60 to 70 parts of calcined building gypsum, 5 to 10 parts of masonry black cement, 0.5 to 1 part of hydroxypropyl methyl cellulose, 0.5 to 1 part of hydroxypropyl starch ether, 0.5 to 1 part of anti-crack fibers, 1 to 1.5 parts of self-leveling composite rubber powder and 0.5 to 1.5 parts of a defoaming agent. According to the invention, the raw materials are separately sieved by using a sieve, then weighed according to a set ratio and uniformly mixed, and an obtained mixture is dried so as to obtain the gypsum. The self-leveling gypsum of the invention has the advantages of good stability, high leveling property, good blow crack resistance effect and few bubbles.
本发明公开了一种自流平石膏，包括按照以下份数配比的原料：60‑70份的锻烧建筑石膏，5‑10份的砌筑黑水泥，0.5‑1份的羟丙基甲基纤维素；0.5‑1份的羟丙基淀粉醚；0.5‑1份的抗裂纤维；1‑1.5份的自流平复合胶粉和0.5‑1.5份的消泡剂，将各组分原料分别进行筛网过筛处理，然后按设定的比例称取各原料组分，将其混合均匀，干燥，即可制得石膏；本发明具有稳定性好，流平性强，抗吹裂效果好、气泡少的优点。
