Magnesium oxychloride low-carbon cementing material with excellent carbonization resistance and preparation method thereof
The invention discloses an anti-carbonization magnesium oxychloride low-carbon cementing material and a preparation method thereof, and belongs to the technical field of modified magnesium oxychloride materials, and the magnesium oxychloride low-carbon cementing material comprises MgO, magnesium chloride hexahydrate, water, polyhedral oligomeric silsesquioxane and PTFE fiber. PTFE fibers and polyhedral oligomeric silsesquioxane with a specific structure are creatively introduced into magnesium oxychloride cement, the stability of a hydrated phase and the binding force among internal particles are improved, pores in the gel material are few, and the bonding strength and compressive strength of the material are improved. Most importantly, the magnesium oxychloride cementing material obtained by adopting the specific components in the scheme of the invention has good carbonization resistance, and the mechanical property of a cement product prepared from the material is not obviously deteriorated after being carbonized for more than 6 months in humid air.
本发明公开了一种抗碳化的氯氧镁低碳胶凝材料及其制备方法，属于改性氯氧镁材料技术领域，该氯氧镁胶凝材料包括MgO、六水氯化镁、水、笼型聚倍半硅氧烷、PTFE纤维。创造性的在氯氧镁水泥中引入PTFE纤维跟具有特定结构的笼型聚倍半硅氧烷，提高了水化相的稳定性以及内部颗粒之间的结合力，凝胶材料内部孔隙较少，提高了材料的粘结强度及抗压强度。最主要的是采用本申请方案的特定组成获得的氯氧镁胶凝材料具有良好的抗碳化性能，该材料制备的水泥制品在潮湿空气中碳化6个月以上机械性能未见明显恶化。
