Cement-based grouting material containing composite fibers and preparation method
The invention discloses a cement-based grouting material containing composite fiber and a preparation method thereof, cement, fly ash, sand and the like are used as main components of the cement grouting material, graphene-cationic polyester composite fiber is used as an additive, cations of the cationic polyester fiber and silicate surfaces in the cement and the sand have a very strong interface effect, and the cement-based grouting material containing the composite fiber is prepared. According to the invention, the polyester fiber is added to enhance the bonding strength between the polyester fiber and the cement grouting material, so that the polyester fiber has a better reinforcing effect, the compressive strength and splitting tensile strength of cement are improved, graphene nanoparticles are uniformly grafted and dispersed to the surface of the polyester fiber, the agglomeration of graphene is reduced, and the reinforcing effect is better; the graphene and the polyester fibers form a composite reinforced fiber material, the double advantages of the graphene nanoparticles and the polymer fibers are exerted, and the mechanical strength of the cement is further improved.
本发明公开了一种含复合纤维的水泥基灌浆料和制备方法，以水泥、粉煤灰、砂子等作为水泥灌浆料的主要成分，石墨烯‑阳离子聚酯复合纤维作为添加剂，阳离子聚酯纤维的阳离子与水泥、砂子中的硅酸盐表面有很强的界面作用，增强了聚酯纤维与水泥灌浆料之间的结合强度，使聚酯纤维起到更好的增强效果，有利于提高水泥的抗压强度和劈拉强度，并且将石墨烯纳米粒子均匀的接枝和分散到聚酯纤维的表面，有利于减少石墨烯的团聚，补强作用更好，使石墨烯和聚酯纤维形成复合增强纤维材料，发挥石墨烯纳米粒子和高分子纤维的双重优势，进一步提高水泥的力学强度。
