| Abstract | A refractory composite polyimide-aluminium foil is composed of two surficial polyimide film layers as sealing layers and an aluminium foil as carrier between said polyimide film layers. It is prepared through preparing resin, dipping films and imination of polyamide acid. Its advantages are high mechanical and sealing performance at -260-260 deg.C, high strength and size stability at low-temp, and high resistance to radiation.
本发明公开了一种聚酰亚胺复合铝箔及其制备方法。本发明涉及一种耐高温的复合材料，具体地说涉及一种聚酰亚胺与铝箔构成的复合材料及其制备方法。本发明的复合材料由作为载体的铝箔和作为密封层的聚酰亚胺薄膜构成，所说的铝箔夹在两层聚酰亚胺薄膜之间。本发明的聚酰亚胺复合铝箔的制备方法包括：1)树脂的制备，2)薄膜的浸渍，3)聚酰胺酸的亚胺化等步骤，本发明的聚酰亚胺薄膜采用GB/13022-92标准进行测试，其结果表明，在-260～260℃的条件下使用，有较高的机械性能和良好的密封性能，耐辐射，尤其在低温状态下，有足够的强度以及尺寸稳定性能，可作为航天火箭等的体外绝热材料。 |
