High-strength two-component anti-crack repair mortar and preparation method thereof
The invention discloses high-strength two-component anti-crack repairing mortar and a preparation method thereof. The anti-crack repairing mortar is composed of a liquid material and a powder material; the liquid material comprises the following components in parts by weight: 600-850 parts of a styrene-butadiene emulsion, 1-2 parts of a defoaming agent, 1-3 parts of a preservative, 150-400 parts of water and 5-15 parts of ethylene glycol; the powder material comprises the following components in parts by weight: 350-600 parts of Portland cement, 1-2 parts of hydroxyethyl cellulose, 1-2 parts of hydroxymethyl cellulose, 2-3 parts of anti-cracking wood fibers, 350-600 parts of quartz sand and 5-15 parts of latex powder; and the weight ratio of the liquid material to the powder material is (1.5-3):1. According to the high-strength two-component anti-crack repairing mortar, the materials are reasonably proportioned, so that the obtained mortar has low shrinkage rate, strong binding power and excellent anti-cracking performance, and the good combination of different materials and additives is fully reflected; the anti-crack repairing mortar has good adaptability to both new and old concrete base layers, is good in water resistance and seepage resistance, has protection performance on reinforcing steel bars, and also has a good holding and wrapping protection effect on rusted reinforcing steel bars.
本发明公开了一种高强度双组份抗裂修补砂浆及其制备方法，该抗裂修补砂浆由液料和粉料组成；液料包括如下重量份的组分：丁苯乳液600‑850份、消泡剂1‑2份、防腐剂1‑3份、水150‑400份、乙二醇5‑15份；粉料包括如下重量份的组分：硅酸盐水泥350‑600份、羟乙基纤维素1‑2份、羟甲基纤维素1‑2份、抗裂木纤维2‑3份、石英砂350‑600份、乳胶粉5‑15份；所述液料和粉料的重量比为1.5‑3:1。本发明的高强度双组份抗裂修补砂浆通过合理配比各材料，得到的砂浆具收缩率低、粘结力强、抗裂性能优异，充分体现了不同材料以及添加剂之间的良性结合；且本发明的抗裂修补砂浆对新旧混凝土基层均有良好的适应性，防水防渗性好，对钢筋具有保护性能，对已锈蚀的钢筋也具有良好的握裹保护作用。
