Improving the atomic oxygen resistance of epoxy resin using organosilicon

  • 摘要: 为了提高航天器树脂材料的抗原子氧剥蚀的性能,把缩水甘油醚氧丙基三甲氧基硅烷加入到环氧树脂中,并对所制成的环氧树脂试样进行原子氧效应地面模拟试验,对试验前后试样的质量损失、表面形貌、表面成分和结构的变化进行了对比和分析.结果表明,添加有机硅烷可以有效地提高环氧树脂的抗原子氧剥蚀性能,试样表面在原子氧的作用下生成了一种三维网状结构,该结构有效地阻止了原子氧对底层材料的进一步剥蚀,使试样的质量损失和剥蚀率明显下降.50h实验之后,添加了质量分数为25.0%的有机硅烷,该材料的剥蚀率约为纯环氧树脂的25%.
