Cement-based composite material and preparation method thereof
The invention provides a cement-based composite material and a preparation method thereof, and belongs to the technical field of composite material preparation. The preparation method comprises the following steps: step 1, preparing a heat-conducting reinforced phase change energy storage microcapsule with uniform and controllable particle size; step 2, preparing a heat-conducting reinforced phase change energy storage microcapsule with controllable wall thickness; and step 3, preparing the phase change energy storage cement-based composite material test piece. Phase change energy storage microcapsules with uniform and controllable particle sizes and enhanced heat conduction are prepared through a micro-fluidic chip, then the wall thickness of the microcapsules is controlled through a layer-by-layer self-assembly method, finally, the wall-thickness-controllable heat conduction enhanced phase change energy storage microcapsules are added into cement paste, the microcapsules are dispersed in the cement paste, and the phase change energy storage microcapsules are prepared. Therefore, the phase-change energy-storage cement-based composite material with good thermal regulation capability is prepared.
本发明提供了一种水泥基复合材料及其制备方法，属于复合材料制备技术领域。本发明包括如下步骤：步骤一、制备粒径均匀可控的导热增强相变储能微胶囊；步骤二、制备壁厚可控的导热增强相变储能微胶囊；步骤三、制备相变储能水泥基复合材料试件。本发明通过微流控芯片制备出粒径均匀可控、导热增强的相变储能微胶囊，再通过层层自组装的方法控制微胶囊的壁厚，最后将壁厚可控的导热增强相变储能微胶囊加入水泥浆体中，将微胶囊分散在水泥浆体中，从而制备出具有良好热调节能力的相变储能水泥基复合材料。
