Application of thermal-insulation refractory gypsum powder
The invention belongs to the field of building materials, and particularly relates to application of a thermal-insulation refractory gypsum powder. The preparation method comprises the following stepsof: pretreating industrial by-product gypsum, preparing a reinforcing material, and carrying out graft modification on shell powder by using latex, then combining a simple and rapid preparation method to prepare the gypsum powder which can be used as a thermal-insulation refractory material to be applied to the building field and the medical field by utilizing byproduct gypsum, so that the gypsumpowder has an average thermal conductivity of 0.037W/(m.k), good thermal insulation effect and good fire resistance when being applied to the building field, and is light in weight, high in hardeningspeed and strong in supporting property when being used for a plaster bandage.
本发明属于建筑材料领域,具体涉及一种保温耐火石膏粉的应用;通过对工业副产石膏的预处理、制备加强材料、采用乳胶对贝壳粉进行接枝改性,再结合简单快捷的制备方法,利用副产石膏生产出一种既可作为保温耐火材料应用于建筑领域,又可应用于医疗领域的石膏粉,使其应用于建筑领域时平均导热率为0.037W/(m·k),保温效果好,耐火性好的建材,作为石膏绷带时质量轻硬化速度快,支撑性强。
