Fireproof cement-based foaming insulation board prepared from solid waste of coal gangue power plant and preparation method
The invention relates to the technical field of building materials, in particular to a fireproof cement-based foaming insulation board prepared from solid waste of a coal gangue power plant and a preparation method. According to the insulation board, a composite cementing material and a composite additive are used as raw material, wherein the composite cementing material comprises ordinary Portland cement, coal gangue power plant fly ash and ultrafine sulphoaluminate cement; and the compound admixtures comprise a pore structure regulator, an activity activator, a retarder, a viscosity regulator, a waterproof agent, an anti-cracking component, a composite water reducing agent, a foaming synergist and a foaming agent. The cement-based foaming insulation board is prepared by taking the ordinary Portland cement, the coal gangue power plant ash and sulphoaluminate cement as the composite cementing material, ultrafine coal gangue power plant furnace bottom slag as the pore structure regulator, and other composite additives as raw materials. Compared with an existing product, the foaming insulation board has the advantages that the volume density is lower, the compressive strength is higher, the heat conductivity coefficient is smaller, the water absorption rate is lower, and the combustion performance can reach the national A-level standard.
本发明涉及建筑材料技术领域，尤其是涉及一种利用煤矸石电厂固废制备的防火水泥基发泡保温板及制备方法。该保温板以复合胶凝材料和复合外加剂为原料；复合胶凝材料包括普通硅酸盐水泥、煤矸石电厂飞灰、超细硫铝酸盐水泥；复合外加剂包括孔结构调节剂、活性激发剂、缓凝剂、黏度调节剂、防水剂、抗开裂组分、复合减水剂、发泡增效剂和发泡剂。该发明以普通硅酸盐水泥、煤矸石电厂灰和硫铝酸盐水泥为复合胶凝材料，超细煤矸石电厂炉底渣为孔结构调节剂，及其他复合外加剂制备的水泥基发泡保温板，该发泡保温板的性能较现有产品具有更低的体积密度、更高的抗压强度、更小的导热系数和更低的吸水率，燃烧性能可达国家A级标准。
