White surface layer gypsum as well as preparation method and application thereof
The invention discloses white surface layer gypsum as well as a preparation method and application thereof, and belongs to the field of building materials. The white surface layer gypsum comprises the following components in parts by weight: 500-570 parts of modified citric acid gypsum, 400-460 parts of heavy calcium carbonate, 2-4 parts of cellulose, 1-3 parts of a retarder and 20-30 parts of ash calcium, the modified citric acid gypsum is obtained by calcining citric acid gypsum powder at a high temperature, adding a surfactant, mixing and irradiating; the surfactant comprises at least one of sodium alginate and sodium abietate. The obtained white surface layer gypsum is high in whiteness, strength and fineness, the problems of yellowing, surface layer cracking, hollowing, frosting and the like cannot occur after the white surface layer gypsum is applied to a wall surface, the problems of color and surface roughness of traditional surface layer gypsum are solved, a putty layer process is omitted, the construction time is shortened, and the construction cost and the secondary maintenance cost are reduced.
本申请公开了一种白色面层石膏及其制备方法、应用，属于建筑材料领域。该白色面层石膏包括如下重量份组分：改性柠檬酸石膏500‑570份、重钙400‑460份、纤维素2‑4份、缓凝剂1‑3份、灰钙20‑30份；所述改性柠檬酸石膏是将柠檬酸石膏粉末高温煅烧后，添加表面活性剂混合，经辐照后获得的；所述表面活性剂包括海藻酸钠、松香酸钠中的至少一种。本申请获得的白色面层石膏白度高、强度高、细度高，且应用于墙面后不会出现泛黄、面层开裂、空鼓、起砂等问题，不仅克服了传统面层石膏颜色及表面粗糙问题，还省去了腻子层工艺，缩短施工时间，降低施工成本及二次维修成本。
