Conductive cement-based composite material based on loaded conductive phase fibers and preparation method of conductive cement-based composite material
The invention relates to a conductive cement-based composite material based on loaded conductive phase fiber and a preparation method thereof, and the preparation method comprises the following steps: adding carrier fiber or carrier fiber suspension into nanoscale conductive phase suspension to obtain a mixed solution; wherein the carrier fibers are PVA fibers or carbon fibers subjected to oxidation treatment; carrying out a heating reaction on the mixed solution, and after the reaction is finished, carrying out cooling, suction filtration and drying to obtain loaded conductive phase fibers; adding the loaded conductive phase fiber into cement, uniformly stirring, adding water, uniformly stirring to obtain cement paste, pouring, curing, demolding and curing the cement paste to obtain the conductive cement-based composite material. According to the invention, the dispersibility of the nano conductive phase in the cement-based material is improved while the performance of the fiber is not influenced, so that the electrical properties and mechanical properties of the nano conductive phase in the cement-based composite material are fully exerted, and the micron-sized fiber and the nano conductive phase cooperate with each other, so that the resistivity of the material is greatly reduced.
本发明涉及一种基于负载导电相纤维的导电水泥基复合材料及制备方法，包括以下步骤：将载体纤维或载体纤维悬浮液加入到纳米级导电相悬浮液中，得到混合液；其中，所述载体纤维为PVA纤维或氧化处理后的碳纤维；混合液进行加热反应，反应结束后经过冷却、抽滤和干燥，得到负载导电相纤维；将负载导电相纤维加入到水泥中，搅拌均匀后加水拌匀得到水泥净浆，所述水泥净浆经过浇筑、固化并脱模养护，得到导电水泥基复合材料。本发明在不影响纤维本身性能的同时提高了纳米导电相在水泥基材料中的分散性，使得纳米导电相在水泥基复合材料中电学性能和力学性能得到充分发挥，微米级纤维和纳米级导电相协同，有利于大幅降低材料的电阻率。
