High-strength impervious iron tailing slag building brick and preparation method thereof
The invention discloses a high-strength impervious iron tailing slag building brick and a preparation method thereof. The building brick is prepared from the following raw materials in percentage by mass: 50-70% of iron tailing slag; 10%-15% of a cementing material; 10%-20% of fine aggregate; 1%-3% of an exciting agent; 1%-3% of a water-based organosilicon waterproofing agent; 0.1%-0.3% of polyvinyl alcohol fiber; 5%-12% of water; the water-based organic silicon waterproof agent is prepared by adopting a silane coupling agent and water-soluble organic silicon oil as raw materials and diisocyanate as a grafting bridge and grafting and copolymerizing the silane coupling agent onto the water-soluble organic silicon oil. According to the iron tailing slag building brick, iron tailing slag waste is effectively utilized, resource reutilization is achieved, environmental protection is facilitated, the iron tailing slag building brick has the advantages of being high in compressive strength, good in impermeability and crack resistance, good in durability and the like, and the comprehensive performance of the iron tailing slag building brick meets or exceeds the requirements of JC/T422-2007 non-sintered refuse tailing brick and other standards.
本发明公开了一种高强抗渗铁尾矿渣建筑砖及其制备方法；该建筑砖的制备原料按照质量百分比包括如下组分：铁尾矿渣50％～70％；胶凝材料10％～15％；细骨料10％～20％；激发剂1％～3％；水性有机硅防水剂1％～3％；聚乙烯醇纤维0.1％‑0.3％；水5％～12％；水性有机硅防水剂是采用硅烷偶联剂和水溶性有机硅油为原料，并以二异氰酸酯为接枝桥梁，将硅烷偶联剂接枝共聚到水溶性有机硅油上制备得到。该铁尾矿渣建筑砖有效利用了铁尾矿渣废料，实现了资源再利用，有利于环保，且其具有抗压强度高、抗渗性能和抗裂性好、耐久性好等优点，其综合性能达到或超过JC/T422‑2007《非烧结垃圾尾矿砖》等标准的要求。
