Preparation method of hollow brick with excellent thermal insulation performance
The invention relates to the technical field of preparation of novel building materials, and discloses a preparation method of a hollow brick with excellent thermal insulation performance, which ensures the strength of a brick body under the condition of improving the thermal insulation property of the hollow brick by controlling the ratio of raw materials for preparing the hollow brick and the conditions of a sintering process, and has the characteristics of low cost, low energy consumption and high performance. According to the invention, the raw material price and energy-saving advantages of coal gangue are fully exerted, wherein the prepared pore-forming agent is doped into the brick body raw material, and the doping amount is controlled, so that the porosity and compressive strength of the hollow brick can be improved, the heat conductivity coefficient of the hollow brick is reduced, and the energy-saving and heat-insulating requirements are met; in addition, the problem of reduction of the porosity and the mechanical strength of sintered bricks due to reduction of the plasticity of brick making raw materials caused by addition of an existing pore-forming agent can be solved,and the heat conductivity coefficient of the prepared heat-preservation sintered hollow brick is remarkably reduced and is as low as 0.19-0.21 W/m.k.
本发明涉及新型建筑材料制备技术领域，公开了一种保温性能优异的空心砖制备方法，通过对空心砖制备原料进行配比以及烧结过程的条件把控，提高空心砖保温性能的情况下保障了砖体的强度，具有低成本、低能耗、高性能的特点；本发明充分发挥了煤矸石的原料价格和节能优势，向砖体原料中掺入制备得到的成孔剂，通过控制掺杂量，不仅能够提高空心砖的气孔率、抗压强度，降低空心砖的导热系数，满足节能保温的要求，还能解决现有造孔剂的添加会降低制砖原料可塑性，导致烧结砖气孔率和力学强度下降的问题，制备得到的保温烧结空心砖导热系数显著降低，导热系数低至0.19‑0.21W/m·k。
