摘要:

真空絕熱板（VIP）是一種A級不燃超高效保溫絕熱材料，導熱系數可達到1~3 mW/(m·K)，保溫效果是傳統保溫材料的5~10倍，常應用于建筑、家電、船舶等領域。芯材是VIP的核心骨架，決定著VIP保溫性能、整體強度以及服役壽命。通過對比分析，分類闡述了4類常見芯材：泡沫類、纖維類、粉體類以及纖維�卜垠w復合類芯材的發展狀況以及各自的優缺點，特別是芯材對VIP板的導熱系數、生產工藝和價格方面的影響；總結了施工應用和研究過程中建筑用真空絕熱板芯材所存在的問題，展望了其發展趨勢。

Abstract:

Vacuum insulation panel (VIP), a kind of ultra�瞖fficient 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�瞤owder 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.
