摘要
文章介绍了国内外有关真空多层绝热材料的产生背景和材料选择、结构设计以及材料热性能影响因素等方面。从杜瓦容器的发明到真空多层材料的形成,从单一刚性体材料到多层柔性体材料,真空绝热材料有了很大程度的发展。国内外学者对真空多层绝热材料的传热进行了研究,为选择更好的辐射屏和间隔材料,设计不同的结构,改变层间状况提供了基础,并对真空柔性材料的设计与研究提供了良好的借鉴。
The background, material selection, structural design, as well as influencing factors on material＇s properties at home and abroad were introduced. From Dewar vessel to vacuum multilayer materials, and from monotonous rigid materials to flexible multilayer materials, vacuum heat insulation materials have great development. Domestic and foreign scholars have done the research on the heat transformation of vacuum multilayer insulation theoretically. It provided the basis to choose a better reflection screen and space to design different structure and change the situation between layers. It＇s a good reference for the design and research of vacuum flexible materials.
