Low-carbon cementing material and preparation method thereof
The invention discloses a low-carbon cementing material and a preparation method thereof, and belongs to the technical field of modified magnesium oxychloride materials, the low-carbon cementing material is prepared from the following raw materials: MgO, magnesium chloride hexahydrate, water, porous rubber microspheres, carbon nanotubes and PVDF fibers, the molar ratio of MgO to magnesium chloride hexahydrate to water is (5-10): 1: (10-15), the mass of the porous rubber microspheres is 1-10% of the mass of MgO, the mass of the carbon nanotubes is 1-10% of the mass of PVDF, and the mass of the carbon nanotubes is 1-10% of the mass of MgO. The mass of the carbon nanotubes is 0%-1% of the mass of MgO, and the mass of the PVDF fibers is 1%-3% of the mass of MgO. According to the low-carbon cementing material, through the combined action of the porous rubber microspheres, the carbon nanotubes and the PVDF fibers, the surfaces of multiphase particles in the material are coated with hydrophobic protective films, the hydrolysis reaction of an internal crystal phase after water soaking is reduced, the water resistance is good, the strength is high, and a product prepared from the low-carbon cementing material has the advantages of being dampproof, waterproof, high in strength, environmentally friendly, low in manufacturing cost, long in service life and the like; the cementitious material has a good market prospect and high economic benefits.
本发明公开了一种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，该低碳胶凝材料由以下原料制备而成：MgO、六水氯化镁、水、多孔橡胶微球、碳纳米管、PVDF纤维，所述MgO、六水氯化镁、水的摩尔比为5~10：1：10~15，所述多孔橡胶微球的质量为MgO质量的1%~10%，所述碳纳米管的质量为MgO质量的0%~1%，所述PVDF纤维质量为MgO质量的1%~3%。该低碳胶凝材料通过多孔橡胶微球、碳纳米管、PVDF纤维共同作用，使得材料内部多相颗粒表面形成疏水保护膜包覆，减少了浸水后内部结晶相的水解反应，耐水性好、强度高，由其制得的产品具有防潮防水、强度高、环保、造价低、使用寿命长等特点，该胶凝材料具有较好的市场前景及较高的经济效益。
