Self-healing inorganic nanocrystal waterproof agent and preparation method thereof
The invention relates to a self-healing inorganic nanocrystal waterproof agent and a preparation method thereof, and belongs to the field of building materials, the self-healing inorganic nanocrystal waterproof agent comprises rice hull ash, a waterproof agent, sodium silicate, nano alumina, sodium sulfate, a sodium alginate solution and organic bentonite; wherein the rice hull ash accounts for 10-25 parts, the waterproof agent accounts for 10-15 parts, the sodium silicate accounts for 5-10 parts, the nanometer aluminum oxide accounts for 15-25 parts, the sodium sulfate accounts for 15-20 parts, the sodium alginate accounts for 10-15 parts, and the organic bentonite accounts for The self-healing inorganic nanocrystal waterproof agent contains active nanocrystal components, can be crosslinked with main components in concrete, provides long-term and effective waterproof protection for a concrete structure by reducing permeability and blocking fine cracks, holes and capillary channels, enables waterproof construction and concrete pouring to be completed synchronously, and has the advantages of simple preparation process, low cost and the like. Under the condition of high water pressure, the effect is remarkable.
本发明涉及一种自愈性无机纳米结晶防水剂及其制备方法，属于建筑材料领域，包括稻壳灰、防水剂、硅酸钠、纳米氧化铝、硫酸钠、海藻酸钠溶液和有机膨润土；其中稻壳灰10～25份、防水剂10～15份、硅酸钠5～10份、纳米氧化铝15～25份、硫酸钠15～20份、海藻酸钠10～15份和有机膨润土5～10份。本发明的自愈型无机纳米结晶防水剂中含有活性纳米结晶组分，可与混凝土中主要成分发生交联作用，通过降低渗透性，封堵细微裂缝、孔洞和毛细管道，为混凝土结构提供长久有效的防水保护，使防水施工与混凝土浇筑同步完成，在高水压条件下，效果显著。
