Preparation method of inorganic salt-ceramic high-temperature phase change composite heat storage material
The invention discloses a preparation method of an inorganic salt-ceramic high-temperature phase change composite heat storage material. The preparation method is specifically implemented according to the following steps: pouring 25-30% of a phase change material NaCl and 69-74% of a ceramic matrix material SiC into a mortar, fully mixing and grinding to fully and uniformly mix the materials, and adding 0.5-1% of aluminum dihydrogen phosphate as a binder in the grinding process to obtain a mixture; pouring the ground mixture into a grinding tool, pressurizing by using a powder tablet press in a one-way pressurizing manner, and then pressing to obtain a cylindrical blank; and putting the blank obtained after compression molding into a pit type resistance furnace, sintering, and carrying out furnace cooling to obtain the NaCl-SiC composite phase change heat storage material. According to the preparation method of the inorganic salt-ceramic high-temperature phase-change composite heat storage material, the problems of serious loss, high material cost and poor heat-conducting property of a phase-change material in the preparation process in the prior art are solved.
本发明公开了一种无机盐‑陶瓷高温相变复合储热材料的制备方法，具体按照如下步骤实施：将相变材料NaCl 25‑30％、陶瓷基体材料SiC 69‑74％倒入研钵中充分混合研磨，使材料充分均匀混合，研磨过程中加入磷酸二氢铝0.5‑1％作为粘结剂，得到混料；将研磨后的混料倒入磨具中，利用粉末压片机，采用单向加压的方式加压，然后压制得到圆柱型胚体；将压制成型后得到的胚体放入井式电阻炉中，进行烧结，随炉冷却后得到NaCl‑SiC复合相变储热材料。本发明的一种无机盐‑陶瓷高温相变复合储热材料的制备方法，解决了现有技术中存在的相变材料在制备过程中流失严重、材料成本高及材料导热性能差的问题。
