Super-crack-resistant rapid repair material and preparation method thereof
The invention discloses a super-crack-resistant rapid repair material and a preparation method thereof, and relates to the technical field of building repair materials. The preparation method of the repairing material comprises the following steps: putting the weighed acid salt cement, ordinary Portland cement, early strength agent, a water reducing agent, rubber powder, a defoaming agent, silica fume, fly ash and quartz sand into a stirrer, adding a composite efficient expanding agent, slowly conducting stirring for 5 minutes to obtain uniform powder, finally adding the diluted acrylic emulsion, and conducting stirring to obtain a finished product. The problems that an existing repairing material is slow in solidification, high in early strength and prone to cracking are solved, generation of microcracks in a base body is reduced, the compactness of the base body is improved, the toughness of the interior of the material is improved, stress concentration is dispersed, generation and expansion of the internal microcracks are reduced, the structure is more compact, the strength is higher, and the crack propagation is blocked, so that the material has excellent anti-cracking performance and early strength, and the later strength is continuously developed.
本发明公开了一种超抗裂快速修复材料及其制备方法，涉及建筑修补材料技术领域。该修复材料的制备方法为：将称取的酸盐水泥、普通硅酸盐水泥、早强剂、减水剂、胶粉、消泡剂、微硅粉、粉煤灰、石英砂投入搅拌机内，并加入复合高效膨胀剂，慢速搅拌5min后得到均匀粉料，最后加入稀释后的丙烯酸乳液，搅拌得到成品。本发明解决了目前修复材料凝固慢、早期强度以及极易产生开裂的问题，减少了基体内部微裂缝的产生，提升了基体密实度，提高了材料内部的韧性，分散了应力集中，减少了内部微细裂缝的产生与扩展，还使结构更加致密，强度更高，裂缝扩展受阻，保证本材料具有优异的抗开裂性能及早期强度，并且后期强度持续发展。
