摘要:: 真空绝热板（VIP）是一种A级不燃超高效保温绝热材料，导热系数可达到1~3 mW/(m·K)，保温效果是传统保温材料的5~10倍，常应用于建筑、家电、船舶等领域。芯材是VIP的核心骨架，决定着VIP保温性能、整体强度以及服役寿命。通过对比分析，分类阐述了4类常见芯材：泡沫类、纤维类、粉体类以及纤维粉体复合类芯材的发展状况以及各自的优缺点，特别是芯材对VIP板的导热系数、生产工艺和价格方面的影响；总结了施工应用和研究过程中建筑用真空绝热板芯材所存在的问题，展望了其发展趋势。

Abstract:: Vacuum insulation panel (VIP), a kind of ultraefficient insulation materials with Class A fire rating, is widely employed in the field of building wall, home appliances and ships, because the thermal conductivity of VIP is lower than 1~3 mW/(m·K) and the insulation efficiency is 5~10 times higher than the traditional insulation material. Core material composes the core skeleton of the VIP and partially determines the insulation performance, overall strength and service life of VIP. In this paper,by comparative analysis, four types of common core materials are classified: the development of foam, fiber, powder, and fiberpowder mixed core materials,including their advantages and disadvantages, especially the influence of core material on the thermal conductivity, production technology and cost. Some issues of the core materials of vacuum insulation panel in practical application and academic research are given and the development trend is proposed.
