Lightweight plastering gypsum and preparation method thereof
The invention discloses lightweight plastering gypsum and a preparation method thereof. The lightweight plastering gypsum is prepared from the following components in parts by weight: 450 to 800 partsof desulfurized gypsum, 150 to 500 parts of coarse whiting, 20 to 50 parts of vitrified micro bubbles, 1 to 5 parts of cellulose, 0.2 to 0.4 part of retarder and 0.15 to 0.25 part of air entraining agent microcapsule. The plastering gypsum is prepared by the following steps: step 1, uniformly stirring a retarder and cellulose to obtain a first product for later use; and 2, crushing vitrified microbeads, adding desulfurized gypsum, coarse whiting, the air entraining agent microcapsules and the crushed vitrified microbeads into the first product, and uniformly mixing all the components to obtain the lightweight plastering gypsum. Due to the adoption of the air entraining agent microcapsules, on one hand, the dispersion uniformity and the flowability among the components can be improved, theconstruction is easy and smooth, and on the other hand, the paving uniformity of plastering gypsum is improved due to the improvement of the flowability.
本发明公开了一种轻质抹灰石膏及其制备方法，包括如下重量份数的组分：脱硫石膏450‑800份、重钙150‑500份、玻化微珠20‑50份、纤维素1‑5份、缓凝剂0.2‑0.4份、引气剂微胶囊0.15‑0.25份。抹灰石膏包括如下的制备步骤：步骤1：将缓凝剂和纤维素搅拌均匀后得第一产物备用；步骤2：将玻化微珠粉碎，将脱硫石膏、重钙、引气剂微胶囊和粉碎后的玻化微珠加入第一产物中混合均匀得到轻质抹灰石膏。由于本发明采用引气剂微胶囊，引气剂微胶囊的加入一方面能够增加各组分之间的分散均匀性和流动性，施工轻松顺畅，同时由于流动性改善，抹灰石膏的铺装均匀性得到改善。
