Solid waste-based cement shaving board and preparation method thereof
The invention provides a solid waste-based cement shaving board and a preparation method thereof, and belongs to the field of cement shaving boards. The cement shaving board is prepared from wood shavings, coal gangue micro powder, composite fiber powder, ordinary Portland cement, water glass, functional auxiliaries and the like. Aiming at the characteristic that the contents of Al2O3 and MgO in the coal gangue micro powder are relatively high, the flammability of the cement shaving board is reduced by utilizing the good high-temperature resistance of the coal gangue micro powder; the impact strength of the cement shaving board is improved by utilizing the fiber characteristic of calcium sulfate whiskers in the composite fiber powder and cooperating with the blast furnace water slag superfine powder and the converter steel slag superfine powder; the synergistic excitation effect of the water glass, the sodium sulfate and the sodium carbonate is utilized to excite the activity of the blast furnace water slag superfine powder and the converter steel slag superfine powder so as to reduce the consumption of ordinary Portland cement. The cement shaving board is prepared from solid waste resources, the purpose of reducing carbon in the field of cementing materials is achieved, and the current industrial development requirements of energy conservation, environmental protection and circular economy are met.
本发明提供了一种固废基水泥刨花板及其制备方法，属于水泥刨花板领域。该水泥刨花板由木刨花、煤矸石微粉、复合纤维粉、普通硅酸盐水泥、水玻璃、功能助剂等制备而成。本发明针对煤矸石微粉中Al2O3与MgO含量较高的特性，利用其良好的耐高温性能，以降低水泥刨花板的易燃性能；利用复合纤维粉中硫酸钙晶须具有的纤维特性，与高炉水渣超微粉与转炉转炉钢渣超微粉协同提高水泥刨花板的冲击强度；利用水玻璃、硫酸钠与碳酸钠的协同激发作用，激发高炉水渣超微粉与转炉转炉钢渣超微粉的活性，以减少普通硅酸盐水泥的用量。本发明利用固废资源制备水泥刨花板，实现胶凝材料领域降炭减碳目的，符合当前节能环保、循环经济的产业发展要求。
