The invention discloses a waste ceramic-based heat insulation brick which comprises raw materials and additives; the raw materials comprise waste ceramic powder, Portland cement and clay, and the additives comprise a dispersing agent, a coagulant, a foaming agent and a polyvinyl alcohol solution. The invention also discloses a preparation method for the waste ceramic-based heat insulation brick. The waste ceramic-based heat insulation brick is foamed at normal temperature, and the aperture is controllable; clay can improve the surface energy of air bubbles in slurry and improve the stability of the slurry, so that the slurry is of a regular spherical structure; by adding polyvinyl alcohol, the viscosity of the slurry is improved, air entering is reduced during high-speed stirring, the pore diameter of the air bubbles is not prone to increasing, finally, the regular waste ceramic-based heat insulation brick with the small pore diameter is prepared, the utilization rate of waste is increased, and meanwhile, the material with the lower heat conductivity coefficient is prepared; and the problems of non-uniform distribution of pores in the material, wide aperture range and the like are solved, and the final material has good properties of light weight, high strength and low heat conductivity.
本发明公开了一种废弃陶瓷基隔热保温砖，包括原料和添加剂；所述原料包括废弃陶瓷粉、硅酸盐水泥和粘土，所述添加剂包括分散剂、促凝剂、发泡剂、聚乙烯醇溶液，本发明还公开了一种废弃陶瓷基隔热保温砖的制备方法。本发明中的废弃陶瓷基隔热保温砖采用常温发泡，孔径可控；且粘土可以改善浆料中气泡的表面能，提高其稳定性，使其呈现规则球形结构；聚乙烯醇的加入提高了浆料的粘度，高速搅拌时减少了空气的进入，气泡孔径不易变大，最终制得了规则的、孔径较小的废弃陶瓷基隔热保温砖，提高废弃物利用率的同时制备出了具有更低导热系数的材料，解决了材料内部气孔分布不均、孔径范围广等问题，最终材料具有质轻、高强、低导热的良好性能。
