Light plastering gypsum and preparation method thereof
The invention discloses light plastering gypsum and a preparation method thereof, and belongs to the technical field of building materials and preparation methods thereof, and the light plastering gypsum is prepared by mixing gypsum powder, basalt fibers, cement, dispersed latex powder, vitrified micro bubbles, an anti-settling agent and a retarder. Basalt fibers are doped into a gypsum powder system, so that the prepared light plastering gypsum has remarkable high-temperature resistance and thermal shock stability, high elasticity modulus and tensile strength and good stability, and can effectively solve the quality problems of cracking, flaking, even peeling and the like in use, and the technical problem that the building appearance quality and the use function are severely influenced. Moreover, the dispersible latex powder adopted in the invention has the characteristics of copolymerization and redispersion, so that the prepared light plastering gypsum has the characteristics of good dispersity, elasticity, water-retaining property, difficulty in freezing, stability and the like, is easy to polish, and is suitable for industrial large-scale production.
本发明公开了一种轻质抹灰石膏及其制备方法，属于建筑材料及其制备方法技术领域，本发明的轻质抹灰石膏由石膏粉、玄武岩纤维、水泥、分散性乳胶粉、玻化微珠、防沉剂和缓凝剂混合制备而成，其中在石膏粉体系中掺入玄武岩纤维使得制备得到的轻质抹灰石膏具有显著的耐高温性能和热震稳定性，高的弹性模量和抗拉强度，稳定性好，可以有效解决使用出现开裂、起壳甚至剥落等诸多质量问题，严重影响了建筑表观质量和使用功能的技术问题。且本发明的分散性乳胶粉具有共聚再分散的特征，使制备得到的轻质抹灰石膏具有良好的和分散性、弹性、保水性、不易冻、稳定性等特点，且易打磨，适合工业化大规模生产。
