The invention provides a high-barrier composite material. The high-barrier composite material comprises a high-barrier functional film, a bonding layer, a framework material layer, a bonding agent layer and a high-barrier TPU film which are sequentially bonded and stacked. The high-barrier composite material meets the requirements of tensile strength under the condition of light weight. Meanwhile,the helium permeability is improved. The high-barrier composite material has excellent composite peel strength, outstanding barrier property, excellent environmental resistance and excellent chemicalresistance. The application in the special space field is met; the process technology has the characteristics of high production efficiency, energy conservation, environmental protection and flexibleprocess technology, and meanwhile, as the textile framework material is low in heating temperature and short in heating time, the strength damage to the framework material is relatively small. And the machining precision is high, and the deviation of film thickness control can be controlled within 0.02mm.

    本发明提供了一种高阻隔复合材料,包括顺次粘合叠加的高阻隔功能膜、粘合层、骨架材料层、粘合剂层和高阻TPU膜。该种高阻隔复合材料,在质量较轻的情况下满足拉伸强度方面的要求。同时提高了透氦性能。具有优异的复合剥离强度、突出的阻隔性、优异的耐环境性能和耐化学性能。满足在特殊空间领域的应用;该工艺技术具有生产效率高、节能环保、工艺技术灵活的特点,同时由于纺织骨架材料受热温度低、时间短,对骨架材料的强力损伤较小。加工精度高,可将膜厚度控制的偏差控制在0.02mm以内。
