| 目的 研究国产双面镀铝聚酯膜的工艺、热物性和耐空间电子质子辐照性能。方法 分析了镀铝聚酯薄膜成形工艺的难点，优化了镀膜工艺，通过测试双面镀铝聚酯膜的厚度、附着力、太阳吸收比、半球发射率，对比了国产与进口镀铝薄膜耐空间电子、质子辐照性能。结果 采用工业化生产流水线的真空镀膜工艺，通过提高靶材纯度和真空度，对聚酯薄膜基材进行处理，降低镀膜时的薄膜温度，制备出了超薄双面镀铝聚酯薄膜，其太阳吸收比为0.09，半球发射率为0.04，满足国外进口镀铝聚脂薄膜标准值的要求。与为辐照试样相比，在2´1016 e/cm2电子辐照剂量和1.5´1015 p/cm2质子辐照剂量的辐照下，镀铝聚酯薄膜的太阳吸收比由辐照前的0.115退化到0.144，半球发射率由辐照前的0.033退化到0.037。结论 通过生产工艺的改进设计，可制备出超薄双面镀铝聚酯薄膜，具有较好的热物性和耐空间电子质子辐照性能。 |

| The work aims to study the process, the thermal properties and the space electron proton radiation resistance of domestic double-sided aluminized polyester films. In order to obtain the high quality and excellent performance of aluminized polyester film, the forming process research of aluminized polyester film was carried out. The difficulties of aluminized polyester film forming process were analyzed and the coating process was improved. The properties of space electron and proton irradiation resistance of domestic and imported aluminized polyester films were compared through the test on the thickness, adhesion, solar absorption and hemispherical emissivity of double-sided aluminized polyester film. The vacuum coating process for industrial production was adopted to treat the polyester film substrate by improving the purity of the target and vacuum, and reduce the film temperature in the coating to prepare ultra-thin double-sided aluminized polyester films. The solar absorption ratio was 0.09 and hemispherical emissivity was 0.04 in conformity with the standard value of imported polyester films. Under the electrons irradiation of 2´1016 e/cm2 and proton irradiation dose of 1.5´1015 p/cm2, the solar absorptance film was reduced from 0.115 to 0.144, and the hemisphere emissivity was reduced from 0.033 to 0.037. double-sided aluminized polyester films with excellent properties and heat resistance of space electron-proton irradiation performance can be prepared by improving the production process. The thermal property data of domestic aluminized polyester film are enriched further to provide experimental basis for the use of the ultra-thin double-sided aluminized polyester film on spacecraft. |
