Capillary crystallization type modified waterproof agent for concrete
The invention relates to a capillary crystalline modified waterproof agent for concrete. The capillary crystalline modified waterproof agent is prepared from the following raw materials in percentage by mass: 25%-35% of alkali metal organosilicate, 4%-6.5% of a surfactant, 6.5%-9.5% of a modified carbon nanotube permeation enhancer, 3.8%-6.6% of tartaric acid, 5.2%-7.8% of N,N-bis(2-hydroxyethyl)isopropanolamine, 1%-2.5% of ethylene glycol and 37%-45% of water. Carbon nanotube grafted polyvinylpyrrolidone adopted by the invention can improve the strength and the overall anti-permeability and anti-seismic performance of the concrete. The waterproof agent has high permeability, the compactness, the strength and the hardness of concrete are enhanced, and the waterproof effect of the same service life as the concrete in the true sense is achieved. The waterproof agent is green and environment-friendly, has concrete workability and is corrosion-resistant and resistant to low temperature. The waterproff agent can be widely applied to construction of various structural projects and concrete pouring, and is simple in production process, low in cost and easy for large-scale production.
一种混凝土用渗透结晶型改性防水剂，各原料的质量百分数为：碱金属有机硅酸盐25%~35%、表面活性剂4%~6.5%、改性碳纳米管渗透增强剂6.5%~9.5%、酒石酸3.8%~6.6%、二乙醇单异丙醇胺5.2%~7.8%、乙二醇1%~2.5%、水37%~45%。本发明采用的碳纳米管接枝聚乙烯吡咯烷酮，可提高混凝土的强度和整体抗渗抗震性能；本发明具有很强的渗透性，还增强了混凝土的密实度、强度和硬度，达到了真正意义上的与混凝土同寿命防水效果；本发明绿色环保、可混凝土和易性、耐腐蚀。耐低温，可广泛应用于各类结构工程的建设和混凝土浇筑，生产工艺简单，成本低廉，易于大规模生产。
