| 摘 要： | 将一定比例的甲基硅树脂与环氧树脂共混，使用固化剂邻苯二甲酸酐固化制得耐烧蚀的有机硅－环氧树脂 ，探讨该树脂的协效残炭及其阻燃性能。结果表明，当甲基硅树脂:环氧树脂=7:3（质量比，下同）时，树脂具有较高残炭率，且出现协效残炭现象；同时，加入10 ％的阻燃剂聚磷酸铵（APP）时，其极限氧指数提高到33 ％，残炭量提高到68 ％。

| Abstract: | Methyl silicone resin（R610）was blended with epoxy resin（E44）,an ablative silicone-epoxy resin was prepared using phthalic anhydride curing systim. The char formation and flame retardant property of the resin were investigated. When mass ratio of R610 and E44 was7:3, the resin had a high char yield and a synergistic effect was observed. Introducing 10 % of the APP flame retardant, the oxygen index of the resin reached 38 %, and the residual carbon content reached 68 %. |
