【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。
[Abstract]:Firstly, the research status of (Vacuum insulation panel,VIP core material, barrier film and getter are summarized, and the influence of different core materials, barrier film and getter on the adiabatic properties and service life of VIP is analyzed. Based on the application requirements of VIP, the optimum structure of VIP for building is put forward, that is, the VIP. of multilayer metal (or oxide) resin composite barrier film coated with ultra-hybrid core and carbon-based oxide composite getter. The VIP not only has the advantages of low heat bridge, good air and oxygen resistance, but also has the advantages of high pressure resistance, flexural resistance, low resilience, piercing resistance and aging resistance. The advantages of fiber type VIP and granular type VIP are brought into full play. At the same time, the advantages of nano-coating and resin film are perfectly combined to overcome the shortcomings of particle type VIP, fibrous type VIP easy to rebound, metal coating defect and resin film easily pierced. In addition, the thermal radiation resistance of carbon-based oxide composite getter is good, which can further improve the adiabatic ability of VIP. Finally, it is pointed out that research and development of high performance and low cost VIP will be the development direction of future research work.
