The invention belongs to the technical field of preparation of building materials, and particularly relates to a preparation method of an antibacterial scouring-resistant foam brick. The preparation method comprises the following steps: firstly, mixing and crushing bagasse and crop straws; mixing a foam liquid with an organic adhesive; soaking a prefabricated brick blank after mixing, and drying after soaking to obtain the antibacterial scouring-resistant foam brick. According to the antibacterial scouring-resistant foam brick and the preparation method thereof, plant fiber components and sucrose components in bagasse and straws form a hydrogen bond adsorption effect through hydroxyl groups, and the foam brick is difficult to bond and adsorb by microorganisms and algae organisms by utilizing good sterilization and disinfection performance of chitosan, so that the compressive strength and the scouring resistance are improved; by introducing silicon dioxide into plant fibers, the fibersare further hydrolyzed and molecular chains are broken through alkali liquor treatment and high-temperature and high-pressure reaction, and meanwhile, silicon dioxide molecules are dissolved to generate silicate components; the pH value is adjusted to enable silicate to generate silicon dioxide molecule particles again, the fibers are filled with the silicon dioxide molecule particles, so that theanti-scouring performance and compressive strength of the foam brick are improved, and the foam brick has wide application prospects.
本发明属于建筑材料制备技术领域，具体涉及一种抗菌耐冲刷泡沫砖的制备方法。本发明首先将甘蔗渣与农作物秸秆混合粉碎，将泡沫液与有机粘合剂混合，混合后浸泡预制砖坯，浸泡后干燥即得抗菌耐冲刷泡沫砖，本发明将甘蔗渣和秸秆中的植物纤维成分以及蔗糖成分，通过羟基基团形成氢键吸附作用，利用壳聚糖良好的杀菌灭菌性能，使泡沫砖难以被微生物、藻类生物粘结吸附，提高抗压强度以及耐冲刷能力；将二氧化硅引入植物纤维中，利用碱液处理和高温高压反应使纤维进一步水解，分子链断裂，同时二氧化硅分子溶解生成硅酸盐成分，通过调节pH值使硅酸盐再次生成二氧化硅分子颗粒填充于纤维中，提高泡沫砖的抗冲刷性能和抗压强度，具有广阔的应用前景。
