摘　　要：介绍了一种J-159结构胶黏剂,用于太阳翼基板结构的板-芯胶接,重点进行了胶黏剂的力学性能、真空挥发性能、耐辐照性能研究,同时开展了典型件的制备及热真空循环试验。结果表明,J-159胶黏剂在150℃下各项力学性能保持率均>56%,远高于常用的J-47胶黏剂,具有很好的耐高温性能。同时,真空挥发性能和耐带电粒子辐照性能满足航天器空间应用要求,制备的典型件在-105~+150℃热真空循环试验后,外观质量、胶接质量及其他性能均符合指标要求,能够满足卫星太阳翼基板耐150℃及以下空间环境的使用需求。This paper introduced a 150℃high-temperature-resistant adhesive J-159 for the core bonding of solar wing substrates and focused on its mechanical properties,vacuum volatility and radiation resistance.At the same time,typical test pieces were prepared and the thermal vaccum cycle tests were carried out.The results show that the retention rate of various mechanical properties of J-159 adhesive at 150℃is more than 56%,which is much higher than the commonly used J-47 adhesive,and has good temperature resistance.At the same time,the vacuum volatility and the resistance to charged particle irradiation meet the requirements of spacecraft space application.After the thermal vaccum cycle test from-105 to+150℃,the prepared typical substrates have qualified appearance quality,bonding quality and other performance indicators,which meet the use requirements of the satellite solar wing substrate to withstand the space environment at 150℃and below.
