Anti-cracking light gypsum keel and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to an anti-cracking light gypsum keel and a preparation method thereof. The preparation method of the anti-cracking light gypsum keel comprises the following steps: (1) uniformly mixing an industrial byproduct calcined gypsum and a pore-forming agent, soaking the mixture in a hydrochloric acid solution, uniformly stirring, filtering to remove the hydrochloric acid solution, and performing washing with water, drying, and crushing to obtain a porous gypsum raw material; (2) mixing the porous gypsum raw material with modified polypropylene fibers, adding water and a dispersing agent, and performing stirring treatment to obtain mixed slurry 1; uniformly mixing the mixed slurry 1 with cement, a retarderand a water reducing agent to prepare slurry; and (3) paving a layer of fiber gridding cloth at the bottom of a mold, injecting the slurry into the mold, then paving a layer of fiber gridding cloth on the surface of the paved slurry, heating and pressurizing the laid mold, and carrying out forming, mold stripping and natural curing. The gypsum keel prepared by the invention is light in weight andgood in anti-cracking performance, and can be used as a ceiling joist.
本发明属于建筑材料技术领域，尤其涉及一种防裂轻质石膏龙骨及其制备方法。所述防裂轻质石膏龙骨的制备方法，包括以下过程：(1)将工业副产熟石膏与致孔剂混合均匀，放入盐酸溶液中浸泡，搅拌均匀后，过滤除去盐酸溶液，水洗，烘干，粉碎，制得孔状石膏原料；(2)将孔状石膏原料与改性聚丙烯纤维混合，加入水和分散剂搅拌处理，获得混合浆料1；将混合浆料1与水泥、缓凝剂、减水剂混合均匀，制得料浆；(3)在模具底部铺一层纤维网格布，将料浆注入模具中，然后在铺设好的料浆表面再铺设一层纤维网格布；将铺设好的模具在加热加压处理，成型，出模，自然养护。本发明制得的石膏龙骨，质量轻，防裂性能好；可应用于吊顶龙骨。
