Carbon oxide nanotube modified cement-based material and preparation method thereof
The invention provides a carbon oxide nanotube modified cement-based material and a preparation method thereof. The cement-based material comprises cement, water, sand, fly ash, carbon oxide nanotubes, a polycarboxylate superplasticizer, polyvinyl alcohol, sodium lignin sulfonate and ethylene glycol. The cement-based material comprises sodium lignin sulfonate, polyvinyl alcohol, carbon oxide nanotubes, ethylene glycol and the like, and the sodium lignin sulfonate and the polyvinyl alcohol have good dispersing capacity and a large number of active groups, can adsorb the carbon nanotubes in an aqueous solution and serve as dispersing media of the carbon nanotubes; the sodium lignin sulfonate, the polyvinyl alcohol and the carbon oxide nanotubes can form a more stable dispersion system, promote a hydration reaction of cement to form a tiny and regular crystal structure, reduce the micropore volume and increase the compactness of the cement-based material.
本发明提供了一种氧化碳纳米管改性水泥基材料及其制备方法，该水泥基材料包括：水泥、水、砂、粉煤灰、氧化碳纳米管、聚羧酸减水剂、聚乙烯醇、木质素磺酸钠和乙二醇。本发明的水泥基材料，包括木质素磺酸钠、聚乙烯醇和氧化碳纳米管和乙二醇等，木质素磺酸钠和聚乙烯醇本身具有的良好的分散能力和大量的活性基团，可以在水溶液中吸附碳纳米管并作为其分散的媒介；木质素磺酸钠和聚乙烯醇和氧化碳纳米管三者不仅可以形成更为稳定的分散体系，促使水泥水化反应形成微小、规整的晶体结构，降低微孔体积，增加水泥基材料的密实度。
