Conductive phase change heat storage concrete and preparation method thereof
The invention discloses conductive phase change heat storage concrete and a preparation method thereof, the conductive phase change heat storage concrete comprises cement, fine aggregate, coarse aggregate, water, a water reducing agent, a phase change material and a conductive filler; wherein the phase change material is a phase change microcapsule; the conductive filler comprises nano carbon black and steel slag. Heat generated after the conductive concrete is electrified can be stored in time, and integration of heat conduction and heat storage of the concrete is achieved. Compared with conventional conductive phase change heat storage concrete, the phase change microcapsules are pre-coated by the nano carbon black, so that organic combination of the conductive filler and the heat storage material is realized, and the heat production and heat storage efficiency is greatly improved. And meanwhile, when the phase change material releases heat, the heat transfer efficiency is effectively improved by the nano carbon black layer with high thermal conductivity.
本发明公开了一种导电相变储热混凝土及其制备方法，包括水泥、细骨料、粗骨料、水、减水剂，还包括相变材料和导电填料；其中所述相变材料为相变微胶囊；所述导电填料包括纳米炭黑和钢渣。本申请中可以及时地将导电混凝土通电后产生的热量储存，实现混凝土的导热蓄热一体化。相较于常规导电相变储热混凝土，纳米炭黑将相变微胶囊的预先包覆实现了导电填料和储热材料的有机结合，大大提高了产热储热效率。同时，在相变材料释放热量时，高导热性的纳米炭黑层有效增加了传热效率。
