Plastering gypsum and preparation method thereof
The invention relates to plastering gypsum and a preparation method thereof, and belongs to the technical field of building materials. The plastering gypsum comprises the following components in parts by weight: 60-90 parts of a fluorgypsum cementing material, 0-10 parts of a light filler, 0.1-0.4 part of a water-retaining agent, 0.5-1.5 parts of a water reducing agent, 0.1-0.5 part of a defoaming agent, 0.01-0.05 part of an air entraining agent and 0-35 parts of other components, and the light filler comprises at least one of glass beads, wood fibers, PP fibers or perlite. The other material comprises at least one of light calcium carbonate, building gypsum, tailing sand, river sand or artificially prepared sand, and the sum of the other material and the light filler is not equal to 0. The invention provides the plastering gypsum produced by using the fluorgypsum, the plastering gypsum is high in strength, small in shrinkage rate, green, environment-friendly and pollution-free, and a new way is opened up for resource utilization of the fluorgypsum.
本发明涉及一种抹灰石膏及其制备方法，属于建筑材料技术领域。本发明所述抹灰石膏包括以下重量配比的组分:氟石膏胶凝材料60～90份，轻质填料0～10份，所述轻质填料包括玻化微珠、木纤维、PP纤维或珍珠岩中的至少一种，保水剂0.1～0.4份，减水剂0.5～1.5份，消泡剂0.1～0.5份，引气剂0.01～0.05份，其它0～35份，所述其它包括轻质碳酸钙、建筑石膏、尾矿砂、河砂或人工制备砂中的至少一种，且其它+轻质填料≠0。本发明提供了一种用氟石膏生产的抹灰石膏，本发明的抹灰石膏强度高、收缩率小、绿色环保无污染，为氟石膏的资源化利用开辟一条新途径。
