Pyrophyllite modified ultrafine slag micro powder and preparation method thereof
The invention relates to pyrophyllite modified ultrafine slag micro powder which is prepared from the following raw materials in parts by weight: 950 to 960 parts of slag, 20 to 30 parts of pyrophyllite, 20 to 25 parts of ultrafine aluminum silicate, 0.1 to 0.5 part of triethanolamine, 0.1 to 0.3 part of triisopropanolamine, 0.2 to 0.4 part of tributyl phosphate , 0.5 to 0.8 part of nano polytetrafluoroethylene, 80 to 100 parts of flue gas desulfurization gypsum, 0.1 to 0.3 part of oleic acid and 0.3 to 0.5 part of sodium sulfate. According to the slag micro powder, the triisopropanolamine, the flue gas desulfurization gypsum, the oleic acid and the sodium sulfate are used, so that residual charges on the surface of the micro powder can be shielded, Si-O bonds in the slag are promoted to break, and the micro powder is prevented from being coagulated, thereby achieving the purpose of reducing energy consumption and mechanical wear; the nano polytetrafluoroethylene is used, so that the surface energy is reduced, particles are prevented from being coagulated, and the dispersibility of the micro powder can be increased; the ultrafine aluminum silicate and the pyrophyllite are used, so that the grinding efficiency and the fineness of the micro powder are increased.
