High-toughness self-insulation cement-based material and preparation method thereof
The invention discloses a high-toughness self-thermal-insulation cement-based material and a preparation method thereof.Fiber, carbon nanotubes and aerogel are added into a cement matrix at the same time, the thermal insulation performance of the cement matrix is improved by adding the aerogel, the mechanical property of the cement matrix is improved by adding the fiber and the carbon nanotubes, and surface modification is conducted on the aerogel, so that the thermal insulation performance of the cement matrix is improved. And thus, the cement can be better dispersed in a cement matrix. The aerogel modified by the silane coupling agent and the carbon nano tube are simultaneously added into a cement matrix, so that the advantage complementation of the material performance is realized. Although the addition of the aerogel may generate a certain negative effect on the mechanical properties of the cement matrix, the introduction of the carbon nanotubes helps to improve the tensile strength and toughness of the cement matrix. Therefore, through the synergistic effect of the two components, the thermal insulation performance of the cement matrix can be improved, the overall mechanical property of the cement matrix can be effectively enhanced, and dual optimization of the structure and energy conservation is achieved.
本发明公开了一种高韧性自保温水泥基材料及其制备方法，在水泥基体中同时加入纤维、碳纳米管和气凝胶，通过加入气凝胶来水泥基体的保温性能，通过加入纤维和碳纳米管来提升水泥基体的力学性能，并对气凝胶进行表面改性，使其能够更好地分散在水泥基体中。本发明通过在水泥基体中同时添加经过硅烷偶联剂改性的气凝胶和碳纳米管，实现了材料性能的优势互补。虽然气凝胶的加入可能会对水泥基体的力学性能产生一定的负面影响，但碳纳米管的引入则有助于提升水泥基体的抗拉强度和韧性。因此，二者的协同作用不仅能够提高水泥基体的保温隔热性能，还能有效增强其整体的力学性能，实现了结构与节能的双重优化。
