Novel shaped ceramic-paraffin composite phase change energy storage material and preparation method thereof
The invention discloses a novel shaped pearl shell structure imitating ceramic-paraffin composite phase change energy storage material and a preparation method thereof, relates to the field of new material preparation, and aims to solve the problems that a phase change energy storage material is relatively low in heat conductivity in the phase change process, the phase change material is easy to leak, the preparation process is complex and the efficiency is low. The material is composed of ceramic powder Al2O3, SiO2, Fe3O4 and industrial paraffin. The pearl shell imitated brick-mud Al2O3 and SiO2 porous ceramic is prepared through magnetic field freezing casting, and the composite phase change energy storage material is obtained after paraffin is infiltrated into the porous ceramic in a non-pressure mode. The composite material has the advantages of high energy storage density, high thermal conductivity, controllable microstructure, no leakage of molten paraffin in the ceramic carrier, high energy storage efficiency and environmental friendliness. A continuous and ordered heat transfer path is constructed by simulating a highly-ordered'brick-mud 'microstructure of pearl shells, so that the porous ceramic skeleton can realize high thermal conductivity and anisotropy.
本发明公开了一种新型定形仿珍珠贝结构陶瓷‑石蜡复合相变储能材料及其制备方法，涉及新材料制备领域，为克服相变储能材料在相变过程中热导率较低、相变材料易泄露，制备工艺复杂、效率低的问题。该材料是由陶瓷粉Al2O3、SiO2、Fe3O4和工业石蜡构成。本发明采用磁场冷冻铸造制备了仿珍珠贝“砖‑泥”Al2O3、SiO2多孔陶瓷，在多孔陶瓷中无压浸渗石蜡后获得复合相变储能材料。复合材料储能密度高、热导率高、微观结构可控，石蜡熔融后在陶瓷载体内不泄露、储能效率高，环境友好。通过模仿珍珠贝高度有序的“砖‑泥”微观结构来构建连续有序的传热路径，可使多孔陶瓷骨架实现高导热率以及各向异性。
