纳米SiO2改性硅树脂天线罩涂层性能测试

摘要

随着现代导弹技术的快速发展，石英陶瓷天线罩得到广泛应用，但因其自身的易吸潮、耐污差等缺点，性能优异的天线罩防潮涂料的研制显得至关重要。本文通过对现有硅树脂进行改性制备了纳米SiO2改性硅树脂涂层，并进行了相关性能测试分析。测试表明。改性后的硅树脂涂层吸水率明显下降，电性能优异，比现有纯硅树脂涂料硬度更高，耐热性更好。%With the rapid development of modern missile technology, quartz ceramic radome has been widely used. In order to prevent moist absorbing and improve the anti-pollution performance of quartz ceramics, a high performance moisture-proof coating should be used. In this paper, a nano-SiO2-modified silicone resin coating was prepared and tested. It was shown that, after being modified by adding nano SiO2, the coating exhibits a significant reduction in water absorption and excellent electrical properties. Furthermore, the modified coating exhibits higher hardness and better heat resistance than the conventional pure silicone resin coating.
