Anti-cracking cement waterproof material and preparation method thereof
The invention relates to an anti-cracking cement waterproof material and a preparation method thereof, and belongs to the technical field of waterproof material preparation. The preparation method comprises the following steps: taking flax fibers as a raw material, mixing and reacting the flax fibers with mussel mucin and catechol oxidase to obtain filter residues, reacting the filter residues with tetraethoxysilane, calcium nitrate and the like, performing calcining to obtain a self-made anti-cracking filler, mixing zeolite with tetraethoxysilane, calcium bicarbonate and trimethylaluminum forreaction to obtain modified zeolite, and finally, compounding the self-made anti-cracking filler, the modified zeolite, Portland cement and other auxiliary materials to finally obtain the anti-cracking cement waterproof material. The anti-cracking cement waterproof material prepared by the preparation method disclosed by the invention is good in crack resistance and excellent in waterproofness, and has a wide application prospect.
本发明涉及一种防开裂水泥防水材料及其制备方法，属于防水材料制备技术领域。本发明首先以亚麻纤维为原料，将其和贻贝粘蛋白以及儿茶酚氧化酶混合反应得到滤渣，再将滤渣和正硅酸乙酯、硝酸钙等反应后煅烧，制得自制防裂填料，接着将沸石和正硅酸乙酯、碳酸氢钙以及三甲基铝混合反应得到改性沸石，最终将自制防裂填料、改性沸石和硅酸盐水泥以及其他辅料复配，最终制得防开裂水泥防水材料；本发明制得的防开裂水泥防水材料，抗裂性好，防水性佳，具有广阔的应用前景。
