摘　　要：对以十水硫酸钠为相变材料的冰晶凉垫的结块现象进行考察,采用均匀设计和优化的方法进行冰晶凉垫防结块剂研究,考察不同变量之间的相互关系,得到防结块剂的最佳配方。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(质量分数)为:十六烷基三甲基溴化铵(0.196%),EDTA(0.194%),十六烷基苯磺酸钠(0.984%),聚丙烯酰胺(1.257%)。当加入质量分数3%防结块剂后,冰晶凉垫无结块现象且稳定性较好。The caking phenomenon of cool mat prepared with Na2 SO4 · 10H2 O was analyzed . Uniform design and optimization software were used in design of anti-blocking agent .The interaction between each variables was investigated and the optimum formula of anti-blocking agent was got .The results show that different variables had highly synergistic effect during their value ranges .The optimum formula of mass fraction is：Cetyl trimethyl ammonium brimide（0 .196% ） ,EDTA （0.194% ） , Sodium （C16 ） alkyl benzene sulfonate （0 .984% ） , Polyacrylamide （1 .257% ） . The cool mat had no caking phenomenon and had high stability when anti-blocking agent was added .
