Fiber cement board based on solid waste-based sulphoaluminate cementing material and preparation method thereof
The invention discloses a fiber cement board based on a solid waste-based sulphoaluminate cementing material and a preparation method thereof, and the fiber cement board is prepared from the following raw materials in parts by mass: 30-45 parts of solid waste-based sulphoaluminate cementing material; 7 parts of wood pulp fiber; 24-36 parts of desulfurized gypsum; 6-9 parts of carbide slag; 3-33 parts of limestone powder; and water, wherein the weight of the water is 4-5 times of the total weight of the above materials. The preparation method comprises the following steps: uniformly mixing the solid waste-based sulphoaluminate cementing material, the desulfurized gypsum, the carbide slag, the limestone powder, the wood pulp fibers and the water to obtain fiber cement slurry; dehydrating the fiber cement slurry to obtain a blank; and performing extrusion forming on the blank, and then performing natural curing. The non-autoclaved preparation of the fiber cement board is realized, the energy consumption is reduced, the production efficiency is improved, and the raw material cost of the fiber cement board is greatly reduced and the resource utilization of the industrial solid waste is realized because the required raw materials except the wood pulp fibers are all industrial solid waste and solid waste-based products.
本发明公开了基于固废基硫铝酸盐胶凝材料的纤维水泥板及制备方法,按照质量份数计,由以下原料组成:固废基硫铝酸盐胶凝材料30~45份;木浆纤维7份;脱硫石膏24~36份;电石渣6~9份;石灰石粉3~33份;以及以上物料质量总和4~5倍的水。制备方法为:将固废基硫铝酸盐胶凝材料、脱硫石膏、电石渣、石灰石粉、木浆纤维和水混合均匀获得纤维水泥料浆;将纤维水泥料浆进行脱水获得料坯;将料坯挤压成型,再进行自然养护。本发明不仅实现了纤维水泥板的免蒸压制备,降低了能源消耗,提高了生产效率,还因所需原料除木浆纤维外均为工业固废及固废基产品,大大降低了纤维水泥板的原料成本,并且实现了工业固废的资源化利用。
