Ternary phase-change cold storage material and preparation method thereof

The invention discloses a low-temperature ternary phase-change cold storage material and a preparation method thereof. The low-temperature ternary phase-change cold storage material to be protected is composed of, by percentage, 16-23% of inorganic salt mixture solution, 1-4% of nucleating agent, 3-7% of inorganic nano thickener, 1-2% of sodium carbonate and water. The preparation method of the ternary phase-change cold storage material is simple in process, short in production cycle, low in cost, non-toxic, environmentally friendly, low in supercooling degree and capable of achieving phase-change latent heat up to more than 200 J/g. 本发明公开了种低温三元相变蓄冷材料以及该低温相变蓄冷材料的制备方法，本发明所要保护的低温相变蓄冷材料，由下列组分配比组成：16～23％的无机盐混合溶液，1～4％的成核剂，3～7％无机纳米增稠剂以及1～2％碳酸钠，其余是水，本发明工艺简单，生产周期短，成本低，无毒环保、过冷度小且相变潜热在200J/g以上。
