Lightweight plastering gypsum as well as preparation method and application thereof
The invention discloses light plastering gypsum as well as a preparation method and application thereof. The light plastering gypsum is prepared from semi-hydrated desulfurized gypsum, heavy calcium carbonate powder, Portland cement, glass beads, latex powder, bentonite, cellulose ether, a water repellent, a retarder and a dispersing agent. Wherein the latex powder is ethylene-vinyl laurate-vinyl chloride terpolymer latex powder; the water repellent is an organic silicon water repellent; the cellulose ether is methyl hydroxyethyl cellulose, and the viscosity of the methyl hydroxyethyl cellulose ranges from 60000 mPa * s to 80000 mPa * s. The light plastering gypsum disclosed by the invention not only has the advantages of small volume density, high strength, good hydrophobicity and good water resistance, but also has the advantages of simplicity in preparation, low cost, high coating rate, convenience in transportation and application and environmental protection in preparation, and is particularly suitable for being used in the field of buildings.
本发明公开了一种轻质抹灰石膏及其制备方法和应用。本发明的轻质抹灰石膏包括：半水脱硫石膏、双飞粉、硅酸盐水泥、玻化微珠、乳胶粉、膨润土、纤维素醚、憎水剂、缓凝剂和分散剂；其中，所述乳胶粉为乙烯‑月桂酸乙烯酯‑氯乙烯三元共聚物乳胶粉；所述憎水剂为有机硅憎水剂；所述纤维素醚为甲基羟乙基纤维素，且所述甲基羟乙基纤维素的粘度为60000mPa·s～80000mPa·s。本发明的轻质抹灰石膏不仅具有体积密度小、强度高、憎水性好(、耐水性好的优势，而且还具有制备简单、成本低、涂布率高、方便运输和应用、制备环保的优势，特别适合用于建筑领域。
