Silica-containing stone-like water-permeable floor mortar and preparation process thereof
The invention relates to the field of mortar, in particular to silicon dioxide-containing stone-like permeable floor mortar and a preparation process thereof, industrial waste residues are introduced into raw materials to serve as aggregate, and the particle size and mass ratio of iron tailing slag, waste glass and biomass power plant ash are controlled; silica fume is introduced to be compounded with industrial waste residues to serve as a composite exciting agent; the preparation method comprises the following steps: treating silica fume by using 3-aminopropyltriethoxysilane and succinic anhydride to carboxylate the silica fume, and then grafting polyamino ionic liquid synthesized by using diethylenetriamine and imidazole to obtain modified silica fume; by adding the bagasse fiber, the complex structure of the cement and the industrial waste residue from macroscopic scale to nano scale is optimized while waste is turned into wealth, and the mortar is endowed with excellent non-deformability and reinforcing ability; bagasse fiber aerogel is prepared by adopting an alkali solvent system to dissolve and regenerate, sodium periodate is adopted to oxidize, and then the bagasse fiber aerogel is grafted with polyamino ionic liquid through Schiff base reaction to obtain the composite bagasse fiber aerogel.
本发明涉及砂浆领域，具体是一种含有二氧化硅的仿石透水地坪砂浆及其制备工艺，在原料中引入工业废渣作为骨料，控制铁尾矿渣、废玻璃、生物质电厂灰的粒径大小与质量比；引入硅灰与工业废渣复配作为复合激发剂；用3‑氨丙基三乙氧基硅烷与丁二酸酐对硅灰进行处理，使其羧基化，然后接枝用二乙烯三胺与咪唑合成的多氨基离子液体，得到改性硅灰；通过添加蔗渣纤维，实现变废为宝的同时，来优化水泥、工业废渣从宏观到纳观尺度的复杂结构，赋予砂浆优秀的抗变形能力与加固能力；采用碱溶剂体系溶解、再生来制备蔗渣纤维气凝胶，采用高碘酸钠氧化，然后通过席夫碱反应与多氨基离子液体进行接枝，得到复合蔗渣纤维气凝胶。
