Conductive cement-based material based on modified aggregate loaded graphene and preparation method of conductive cement-based material
The invention discloses a conductive cement-based material based on modified aggregate loaded graphene and a preparation method of the conductive cement-based material. The nano graphene is firmly dispersed and loaded on the aggregate subjected to surface modification treatment, so that the dispersity of the nano graphene in the cement-based material is improved while the excellent performance of the graphene is not influenced, and the electrical property and the mechanical property of the nano graphene in the cement-based composite material are fully exerted; meanwhile, by adding a very small amount of carbon fibers to connect the graphene-loaded aggregate, the resistivity of the cement-based material can be greatly reduced, a very small amount of graphene is loaded on the surface of the modified aggregate and cooperates with the very small amount of carbon fibers, the conductivity of the cement-based material is remarkably improved, and the micromechanical property of an interface between the aggregate and a hydration product is improved; the method is simple in process, low in cost, good in loading effect and beneficial to large-scale popularization and utilization.
本发明公开一种基于改性骨料负载石墨烯的导电水泥基材料及其制备方法。本发明通过将纳米石墨烯牢固分散负载在表面改性处理后的骨料上，在不影响石墨烯本身优异性能的同时提高了纳米石墨烯在水泥基材料中的分散性，使得纳米石墨烯在水泥基复合材料中电学性能和力学性能得到充分发挥；同时，通过加入极少量碳纤维连接负载石墨烯后的骨料，就能够大幅降低水泥基材料的电阻率，极少量的石墨烯负载在改性骨料表面并协同极少量的碳纤维，显著提高水泥基材料的导电性，并改善骨料与水化产物界面的微观力学性能；本发明的工艺简单、成本较低、负载效果良好，有利于大规模推广利用。
