摘　　要：选用开孔聚氨酯作为真空绝热板的芯材,讨论了该芯材开孔率、容重、孔径和强度对真空绝热板隔热性能的影响以及真空度对芯材的影响。介绍了芯材预处理工艺。结果表明,使用开孔聚氨酯作为真空绝热板的芯材,导热系数可以降到10 mW/(m.K)以下。Open-cell rigid polyurethane form was taken as core matrial for the vacuum insulated panel, and the effects of open-cell agents, density, cell-diameter and intensity on the vacuum insulated panel were discussed. The effect of vacuum degree on it was also discussed. The pre-treat technology of vacuum insulated panel was introduced. If the open-cell rigid polyurethane form is taken as the core, the vacuum insulated panel＇s thermal conductivity can be less than 10mW/（m·K）.
