摘　　要：对十水硫酸钠相变储能材料在使用过程中出现的过冷和结块问题进行了分析,采用均匀设计和优化的方法对这2个问题进行了研究,考察了不同变量之间的相互关系,得到最佳实验配方。结果表明,在相应的取值范围内,配方中变量之间均有较强的协同作用。最佳配方为:硼砂1.146%,纳米二氧化硅1.536%,羧甲基纤维素钠1.526%,十六烷基三甲基溴化铵1.250%,EDTA0.257%,聚丙烯酸钠0.421%,十六烷基苯磺酸钠0.912%,制得的十水硫酸钠相变储能材料无过冷和结块现象,且储热性能良好。This paper analyzed the cool mat and caking problems occurred during the using of Na2SO4·10H2O phase change materials,researched the two problems with uniform design and optimization method,investigated the relationship between different variables and obtained the optimum formula. The results show that within corresponding value range,there is strong synergistic effect between different variables. The optimum formula in mass fraction can be described as 1.146% Borax,1.536% Nano silicon dioxide,1.526% CMC,1.250% Cetyl trimethyl ammonium bromide,0.257% EDTA,0.421% Sodium polyacrylate,0.912% Mono（C16）alkyl benzene sulfonic acid sodium salt. The phase change materials prepared by this formula have no cool mat and caking problem,and have excellent heat storage capacity.
