正交试验法研究定形复合相变材料的制备工艺
Study on the preparation technology of composite phase change material by using orthogonal tests
摘要
Abstract
In order to prepare shape-stabilized phase change material, composite phase change material was prepared by sol-gel. Shape material was obtained by sol-gel with TEOS, in which phase change material was auric acid/cetyl alcohol binary eutectic phase change materials. The results showed that the descending order of the influencing factors: ester-PCM ratio, ester-water ratio, pH, the reaction temperature, aging temperature. The best technology is: the ester-water ratio 1: 8, ester-PCM ratio 1 : 2.3, pH 3, aging temperature 85 ℃, the reaction temperature 60 ℃. When composite phase change material was prepared with the best technology, phase transition temperature of composite phase change material is 34 ℃, phase change enthalpy can reach 122.4 J/g when the mass fraction of phase change material is 64%.关键词
