Preparation method of waterproof anti-crack mortar
The invention relates to the technical field of mortar, in particular to a preparation method of waterproof anti-crack mortar. Comprising the following raw materials in parts by weight: 28-42 parts of cement, 20-30 parts of mineral powder, 20-35 parts of silica fume, 40-60 parts of quartz sand, 10-20 parts of fibers, 8-15 parts of magnesium phosphate whiskers, 8-16 parts of a carbon quantum dot solution, 0.8-1.2 parts of an ethylene-vinyl acetate copolymer emulsion, 0.5-0.9 part of a water reducing agent, 0.4-0.7 part of a water repellent and 30-40 parts of water. The preparation method comprises the following steps: uniformly mixing a part of inorganic materials in a dry stirring manner, uniformly dispersing fibers, magnesium phosphate whiskers, a carbon quantum dot solution, an ethylene-vinyl acetate copolymer emulsion, a water reducing agent and a water repellent with water, and mixing dry powder with a mixed solution again; the porosity of the cured mortar can be reduced, the cured mortar is smooth and uniform in surface and high in particle density, the impermeability of the cured mortar is improved, the waterproof performance of the mortar is improved, the ductility, crack resistance and strength of the mortar are enhanced, and the mechanical property is stable.
本发明涉及砂浆技术领域，具体涉及一种防水抗裂砂浆的制备方法；包括原料有水泥28～42份、矿粉20～30份、硅灰20～35份、石英砂40～60份、纤维10～20份、磷酸镁晶须8～15份、碳量子点溶液8～16份、乙烯‑醋酸乙烯酯共聚物乳液0.8～1.2份、减水剂0.5～0.9份、憎水剂0.4～0.7份，水30～40份；本发明先将部分无机材料干拌混合均匀，再将纤维、磷酸镁晶须、碳量子点溶液、乙烯‑醋酸乙烯酯共聚物乳液、减水剂和憎水剂与水分散均匀，干粉与混合液再次拌合；可以减少砂浆固化后的孔隙率，使得砂浆固化后表面光滑均匀，颗粒密度高，砂浆固化后抗渗性能提高，有利于砂浆防水性的提高，增强砂浆的延性、抗裂性以及强度，力学性能稳定。
