The invention belongs to the technical field of building materials, and particularly relates to a coal gangue sintered hollow wallboard and a preparation method thereof. In order to treat coal gangue to a large extent, improve the utilization rate and the additional value of the coal gangue, solve the problems of land occupation and environmental pollution caused by large accumulation of the coal gangue and provide a coal gangue wallboard capable of meeting the national performance standard, the invention provides a hollow wallboard sintered from the coal gangue. The preparation method comprises the following steps: uniformly mixing 40-50% of coal gangue, 20-30% of Huapi clay, 10-20% of river sand powder, 5-8% of acetylene plant calcium carbide waste residue powder, 2-5% of calcium aluminate cement and 0.5-1% of titanium slag smelting dust collection powder to obtain a mixture, adding water, uniformly stirring, and carrying out extrusion molding and high-temperature calcination. The normal-temperature compressive strength of the prepared sintered hollow wallboard is 19.5 MPa, which is far higher than that of other sintered hollow wallboards on the market, and the sintered hollow wallboard has important significance on environment-friendly utilization of coal gangue resources.
本发明属于建筑材料技术领域,具体涉及煤矸石烧结中空墙板及其制备方法。为了能较大限度处理煤矸石,提高煤矸石的利用率和附加值,解决煤矸石因大量堆积而造成的土地占用和污染环境问题,同时提供能满足国家性能标准的煤矸石墙板,本发明提供一种煤矸石烧结中空墙板,其是将煤矸石40~50%、华坪粘土20~30%、河砂粉10~20%、乙炔厂电石废渣粉5~8%、铝酸钙水泥2~5%和钛渣冶炼收尘粉0.5~1%混匀后得混合料,加水,搅匀,经过挤塑成型、高温煅烧获得。制备的烧结中空墙板常温耐压强度为19.5MPa,远远高于市面上其他烧结中空墙板,对于煤矸石的资源环保利用具有重要意义。
