摘　　要：高海拔大气环境对RTV涂层的性能有不同程度的影响,针对此类现象,采用紫外老化、高低温交变老化、盐雾老化等三方面老化试验模拟高海拔环境RTV大气老化过程。紫外老化试验及高低温交变老化试验表明紫外线和高低温交变对RTV涂层憎水迁移性有着较为明显的影响,而盐雾环境对RTV涂层性能影响较小。High altitude atmospheric environment has different degrees of influence on the performance of RTV coating.In view of this phenomenon,UV aging,high and low temperature alternating aging and salt spray aging tests were used to simulate the atmospheric aging process of RTV in high altitude environment.Uv aging test and high and low temperature alternating aging test show that UV and high and low temperature alternating have obvious effects on the hydrophobic transfer of RTV coating,while salt spray environment has little effect on the performance of RTV coating.
