Thermal insulation type plastering gypsum and preparation method thereof
Compared with the prior art, the heat-preservation plastering gypsum provided by the invention has the advantages that the gypsum reinforcing agent is added, so that the plastering gypsum has higher strength on the basis of adding light aggregate, the flowability of gypsum slurry can be enhanced, the water consumption is reduced, and the reduction of the strength in the gypsum hydration process is further reduced; meanwhile, fly ash and silicate filler are doped to improve the structure of a gypsum hydrated hardened body, and fibers are introduced to avoid the problems of cracking and the like, so that all performance parameters of the finally obtained heat preservation type plastering gypsum meet the GB/T28627-2012 standard requirements, the heat conductivity coefficient of the hydrated hardened body is smaller than 0.1 W/(m.K), the dead weight of a room structure can be reduced, sound insulation, fire prevention, heat preservation and heat insulation can be achieved, and the heat preservation type plastering gypsum can be widely applied to the field of heat preservation and heat preservation. And the human settlement environment quality is improved.
本发明提供了一种保温型抹灰石膏，与现有技术相比，本发明通过加入石膏增强剂使抹灰石膏在增加轻集料的基础上也具有较高的强度，并且还可增强石膏浆体的流动性，降低用水量，进一步减少石膏水化过程中强度的降低，同时掺加粉煤灰及硅酸盐填料提高石膏水化硬化体结构，引入纤维避免开裂等问题，从而使最终得到的保温型抹灰石膏各项性能参数均符合GB/T28627‑2012标准要求，水化硬化体导热系数＜0.1W/(m·K)，既可减轻居室结构自重，又可实现隔声、防火、保温、隔热，提高人居环境质量。
