十八烷酸复合相变储能材料的制备及性能研究
|
摘要
本文采用溶胶凝胶法,以十八烷酸作为相变储能物质,正硅酸乙酯为硅源水解形成的SiO_2为载体,合成出相变潜热高、热稳定性好、封装性能好、能有效解决泄漏问题的十八烷酸/二氧化硅复合相变储能材料,并且探究了反应物用量和反应环境对制备复合相变储能材料的影响。
By sol-gel method, stearic acid was used as phase change energy storage material, and tetraethyl orthosilicate was used as silicon source to form carrier. The experimental conditions were optimized to synthesize the SA@SiO_2 composite phase change energy storage material with large latent heat, high thermal stability, good package performance and effective solution to leakage problems, the influence of reactant amount and reaction environment on the preparation of composite phase change energy storage materials were explored.
