Preparation method of heat storage material

The invention discloses a preparation method of a heat storage material, which comprises the steps of mixing solid paraffin, liquid paraffin, hexadecylamine and nano aluminum nitride step by step, controlling conditions such as temperature and pressure during preparation, and finally packaging. The heat storage material has the advantages of wide phase change temperature, low melting point, high latent heat, good thermal conductivity, low cost and difficult leakage. 本发明公开了一种储热材料的制备方法，分步骤将固体石蜡、液体石蜡、十六胺和纳米氮化铝混合，制备中要控制温度和压强等条件，最后进行封装。该储热材料相变温度宽，具有较低的熔点和较高的潜热，导热性好，成本低，不容易泄露。
