Modified layered silicate as well as preparation method and application thereof
The invention relates to the technical field of building materials and chemical building materials, in particular to modified layered silicate as well as a preparation method and application thereof. The preparation method of the modified layered silicate comprises the following steps: (1) taking layered silicate and an alkaline solution as raw materials, uniformly stirring, and drying to obtain hydroxyl-activated layered silicate; and (2) reacting the hydroxyl-activated layered silicate with a coupling agent for 1-2 hours, and roasting at 120-180 DEG C for 2-3 hours. When the modified layered silicate prepared by the method is used in anti-corrosion concrete, the hydrophobicity of the concrete can be improved, and the corrosion resistance coefficient of the concrete is improved by 16-23%.
本发明涉及建筑材料和化学建材技术领域，尤其涉及一种改性层状硅酸盐及其制备方法与应用。所述改性层状硅酸盐的制备方法包括如下步骤：(1)以层状硅酸盐和碱溶液为原料，搅拌均匀后，烘干得羟基活化的层状硅酸盐；(2)将所述羟基活化的层状硅酸盐和偶联剂反应1～2h后，在120～180℃下焙烧2～3h。利用上述方法制得的改性层状硅酸盐在防腐蚀混凝土中使用时，能够增加混凝土的疏水性，混凝土抗蚀系数提升16～23％。
