The invention belongs to the technical field of building material preparation, and particularly relates to a preparation method of a high-strength weather-resistant sandstone plate. The preparation method comprises the following steps: taking cement, river sand, montmorillonite, lecithin and the like as raw materials; and drying and curing to obtain the high-strength weather-resistant sandstone plate; foaming by utilizing the surface activity of lecithin; providing rich pore structures to the green body; impregnating the green body with a sodium silicate solution and adjusting the pH value with hydrochloric acid; and coating the sandstone plate framework with a firm and compact nano silicon dioxide layer; so that the mechanical strength of the sandstone plate is improved; meanwhile, the weather-resistant effect is also achieved; in addition, montmorillonite in the sandstone plate slurry has the effect of preventing weathering caused by ultraviolet oxidation; meanwhile, silicon hydroxylin montmorillonite and silicon hydroxyl on the surface of nano silicon dioxide can improve the mechanical strength of montmorillonite, a compact polymer film layer finally formed on the surface of silicone acrylic emulsion can be prevented from being in direct contact with the outside, the weather resistance of the sandstone plate is improved, and the sandstone plate has a wide application prospect.
本发明属于建筑材料制备技术领域，具体涉及一种高强度抗风化砂岩板的制备方法。本发明首先以水泥、河砂、蒙脱土、卵磷脂等为原料，干燥固化后即得高强度抗风化砂岩板，利用卵磷脂的表面活性可以发泡，赋予生坯丰富的孔隙结构，随后利用硅酸钠溶液浸渍生坯并利用盐酸调节酸碱度，使得砂岩板骨架被包覆上一层坚固致密的纳米二氧化硅层，提高砂岩板力学强度的同时又起到了抗风化的作用，另外砂岩板浆料中的蒙脱土具有防止紫外氧化造成的风化作用，同时蒙脱土中硅羟基和纳米二氧化硅表面的硅羟基，可提高其机械强度，硅丙乳液最终在表面形成的致密聚合物膜层可以避免和外界直接接触，提高了砂岩板的抗风化能力，具有广阔的应用前景。
