中文摘要:
      首先概述了真空绝热板(Vacuum insulation panel,VIP)芯材、阻隔膜和吸气剂的研究现状,分析了不同芯材、阻隔膜和吸气剂对VIP的绝热性能和使用寿命的影响,并基于VIP的应用要求提出了适用于建筑用VIP的最佳结构,即多层金属(或氧化物)树脂复合阻隔膜包覆超混杂复合芯材和碳基氧化物复合吸气剂的VIP。该VIP不仅具有低热桥、阻气阻氧性能好的优点,还具备耐压、耐折、回弹性低、抗刺穿和耐老化的优良特性,充分发挥了纤维型VIP和颗粒型VIP的优点,同时完美结合了纳米涂层与树脂膜的优势,克服了颗粒型VIP易溃散、纤维型VIP易回弹、金属镀层缺陷大和树脂膜易刺穿的缺点。此外,碳基氧化物复合吸气剂的抗热辐射性能良好,可进一步提高VIP的绝热能力。最后指出研究和开发高性能、低成本的VIP将是未来研究工作的发展方向。
英文摘要:
      This paper summarizes the research status of each unit component of vacuum insulation panel(VIP), i.e., core material, barrier envelope, and getter. The effect of different core materials, barrier envelopes and getters on the thermal conductivity and service life of VIPs is analyzed. A novel VIP structure which is made up of multilayer metallic (oxidation) resin composite barrier envelope, composite core materials and carbon-based oxidation getter is proposed based on the application acquirement of VIPs in the buildings. The new VIP has not only the advantages of low thermal bridge and perfect resistance of gas and oxygen, but also possesses good performance of pressure resistance, folding resistance, low resilience, perfect penetrating resistance, and aging resistance. And, the new VIP takes advantages of fibrous and particle VIPs and combines the merits of nano-coating and resin film. Furthermore, it overcomes shortcomings of the particle VIPs, which are easy to collapse, the fibrous VIPs, which are easy to rebound, the metallic coatings, which are easy to defect and the resin films, which are easy to be punctured. In addition, the application of carbon-based oxidation getter can further improve the insulation ability of VIP as its great resistance to the thermal radiation. Finally, it is pointed out that the research and improvement of VIPs with high performance and low cost will be the development direction of future research work.
