摘要
Abstract
Selecting EPDM and HDPE as coating materials, and paraffin as phase change material, the shape-stabilized phase change material was prepared through thermal melting method. The results of constant temperature thermal aging test show that: when the content of paraffin is 60%, the mass loss rate of paraffin in EPDM-base shape-stabilized phase change materials is less than 1%, which is far lower than that of paraffin in HDPE-base shape-stabilized phase change materials, 9.44%. The constant water bath test shows that: with the increasing of water bath time, the mass loss rate of shape-stabilized phase change material increases; when the content of paraffin is more than 60%, the sealing effect of EPDM on paraffin gets worse, and the mass loss rate increases clearly; the sealing effect of EPDM-base shape-stabilized phase change material is better than that of HDPE-base shape-stabilized phase change material at the same conditions.关键词
