Concrete anti-cracking and anti-seepage reinforcing agent and preparation method thereof
The invention discloses a concrete anti-cracking and anti-seepage reinforcing agent and a preparation method thereof. The concrete anti-cracking and anti-seepage reinforcing agent is prepared from cellulose ether, polymer emulsion, cement, nano silicon dioxide, polyacrylamide particles, polyurethane, steel fibers, calcium sulphoaluminate, alkyl sulfonate, a waterproof agent and a mineral admixture. According to the anti-cracking and anti-seepage reinforcing agent for the concrete, by adding cellulose ether and polyacrylamide particles, the cohesiveness and toughness of the concrete are improved, formation of cracks is reduced, and the tensile strength and anti-cracking performance of the concrete are further enhanced by adding steel fibers; the nano silicon dioxide and the polyurethane reinforcing agent are used for filling micropores in the concrete, so that the permeability is remarkably reduced, and the waterproof performance of the concrete is improved by matching with the addition of the waterproof agent. By adopting the polymer emulsion and the alkyl sulfonate, the workability and the flowability of the concrete are improved, and the comprehensive performance of the concrete is improved by adding the mineral admixture. The anti-cracking and anti-seepage mortar has remarkable anti-cracking and anti-seepage performance.
本发明公开了一种混凝土防裂抗渗增强剂及其制备方法，该混凝土防裂抗渗增强剂包括纤维素醚、聚合物乳液、水泥、纳米二氧化硅、聚丙烯酰胺颗粒、聚氨酯、钢纤维、硫铝酸钙、烷基磺酸盐、防水剂以及矿物掺合料。该混凝土防裂抗渗增强剂通过添加纤维素醚和聚丙烯酰胺颗粒提高了混凝土的粘结性和韧性，减少了裂缝的形成，钢纤维的加入进一步增强了混凝土的抗张强度和抗裂性能；采用纳米二氧化硅和聚氨酯增强剂填充混凝土内部的微细孔隙，显著降低了渗透性，配合防水剂的加入提升了混凝土的防水性能。采用聚合物乳液和烷基磺酸盐改善了混凝土的和易性和流动性，还通过矿物掺合料的加入提升了混凝土的综合性能。本发明具有显著的抗裂、抗渗性能。
