环氧树脂-磷酸氢二钠复合相变储能材料的制备与性能研究

Studied for epikote-sodiam dihydrogen phosphate complex material of phase change energy storage

相变储能具有工艺简单、使用方便、成本低廉等优点,近年成为能量利用、系统控温等领域中的研究热点。研究以固化环氧树脂为载体材料、Na_2HPO_4·12H_2O为相变功能材料,获得了一种定形复合相变储能材料。实验制备材料的热分析、IR光谱等研究表明,获得的复合材料在低于100℃的温度段具有多个相变峰;总相变潜热较高;固化环氧树脂能较好地将Na_2HPO_4·12H_2O包裹,它们之间为简单的物理作用。

Storage energy by phase change have more advantage, for example, simplify craft, advantageous use, low price costing. It is a focal point in utilization of energy and temperature controlling of system. This study deals with a new preparation method for complex material of phase change storage. Results obtained from DSC and IR showed, that the complex material has more than one peak of phase change among the temperature blow 100℃ ,and the total latent heat of the complex material is more great. In the complex phase change material,the Na2HPO4· 12H2O was encapsulated with epikote. There are no chemical reactions that between the supporter of epikote and the unit of phase change material.
