摘　　要：本文以纤维多孔陶瓷为基体,无机水合盐为相变材料,熔融浸渍法制备了复合蓄热材料。通过对制备工艺的优化,得出浸渍方式为完全浸渍,浸渍温度为98℃,浸渍时间为12min的条件下制备出蓄热性能良好的复合蓄热材料,浸渍率高达83.17%。Hydration inorganic salt was chosen as the phase change material and the porous ceramic was chosen as the skeleton in this paper. The composite heat storage material prepared by using the melt- soaking method is presented. After the process optimization, the composite heat storage material with high heat storage capacity whose impregnation ratio was up to 83.17% was prepared, under these eonditions： complete impregnate manner; impregnate temperature 98 ℃; impregnate time： 12 min.
