Waterproof mortar with high compressive strength and preparation method thereof
The invention relates to waterproof mortar with high compressive strength and a preparation method thereof, and belongs to the technical field of building material preparation. The preparation methodcomprises the following steps: by taking silicate minerals as raw materials, crushing, impregnating with citric acid for acid etching to improve the surface roughness of the crushed materials, mixingand calcining the crushed materials with potassium thiocyanate, mixing and impregnating with dopamine and a metal salt, and soaking and reducing with a potassium borohydride solution after impregnation to obtain a metal compounded self-made compression-resistant filler. taking radix puerariae rich in starch and cellulose as a raw material, crushing, cooking at high temperature and high pressure, reacting with phenol to prepare a self-made waterproof slurry, and finally blending and reacting the self-made waterproof slurry, the self-made compression-resistant filler, Portland cement, organosiloxane and other auxiliary materials to finally prepare the waterproof mortar with high compressive strength. The prepared waterproof mortar is high in compressive strength and good in waterproof performance, and has a wide application prospect.
本发明涉及一种高抗压强度防水砂浆及其制备方法，属于建筑材料制备技术领域。本发明首先以硅酸盐矿物为原料，粉碎后经柠檬酸浸渍酸蚀，提高粉碎物的表面粗糙度，接着将其和硫氰化钾混合煅烧后与多巴胺以及金属盐混合浸渍，浸渍后用硼氢化钾溶液浸泡还原得到金属复合后的自制抗压填料，接着本发明以富含淀粉和纤维素的葛根为原料，将其粉碎后高温高压蒸煮，并和苯酚反应制备得到自制防水浆料，最后将自制防水浆料和自制抗压填料以及硅酸盐水泥、有机硅氧烷和其他辅料共混反应，最终制得高抗压强度防水砂浆，本发明制得的防水砂浆抗压强度高，防水性能好，具有广阔的应用前景。
