Zusammenfassung: | The invention relates to the technical field of fracturing propping agents, and particularly discloses a fracturing propping agent taking solid waste ceramsite sand as a raw material and a preparation method of the fracturing propping agent. The fracturing propping agent taking the solid waste ceramsite sand as the raw material is mainly prepared from the following raw materials: bauxite; solid waste ceramsite sand; a sintering aid; sepiolite; dolomite; kaolin; an additive; the additive is at least two of phosphosiderite, titanium oxide and manganese powder; an auxiliary agent; the auxiliary agent is composed of wollastonite whiskers, bentonite and modified aluminum oxide, and the preparation method of the modified aluminum oxide comprises the following steps: mixing calcium carbonate, aluminum oxide and silicon oxide, and then calcining, cooling and grinding to obtain the modified aluminum oxide. The preparation method comprises the following steps: mixing the raw materials to obtain a mixture; the mixture i |
