The invention belongs to the field of environment-friendly materials, and particularly relates to a sponge brick and a preparation method thereof. The method comprises the following steps: 1) crushing, sieving and uniformly mixing a base material, adding water for aging, adding a binding agent, uniformly mixing, and pressing to obtain a green brick; and 2) placing the green brick in a mold for presintering after standing, uniformly distributing chromium salt on the surface of the green brick for high-temperature sintering, and cooling to obtain the sponge brick. According to the technical scheme, it is guaranteed that the sponge brick is uniform and consistent in overall density, free of layering after firing, good in abrasion resistance, not prone to cracking and large in flexural and compressive strength, the water seepage capacity of the sponge brick is improved, meanwhile, the mechanical property of the sponge brick is improved, the thermal shock resistance of the sponge brick is guaranteed, and the service life of the self-heat-preservation building block is prolonged.
本发明属于环保材料领域，具体涉及一种海绵砖及其制备方法。所述方法包括：1)取基料进行破碎过筛并混合均匀，掺水陈化，加入结合剂，混合均匀后压制得到砖坯；2)静置后将砖坯置于模具中进行预烧结，于砖坯表面均匀分布铬盐进行高温烧制，降温得到海绵砖。本发明技术方案确保海绵砖整体密度均匀一致，烧制后不分层、耐磨性好、不易破裂、抗折抗压强度大，提升了海绵砖的渗水能力，同时提升了海绵砖的力学性能，并保障了海绵砖的耐热震能力，延长自保温砌块的使用寿命。
