| 摘 要： | 本文通过Diels-Alder反应合成了四苯(基)苯基三乙氧基硅烷及四苯(基)苄基三乙氧基硅烷,产率均为96％左右。并作了下列耐热性研究:(1)把两种化合物分别作为硅橡胶混炼时的热稳定剂,所得硅弹性体其热老化稳定性及机械强度均较好。(2)把两种化合物分别作为室温硫化硅橡胶固化时的交联剂,所制得的胶片在350℃老化10小时仍保持弹性。(3)两种化合物分别与H_3BO_3反应,制得耐热性硅硼树脂,是一种优良的耐高温涂料。

| Abstract: | The following compounds have been synthesized by Diels-Alder reaction in 96% yield.Compounds Ⅰ, Ⅱ were used as additives for compounding of silicone rubber. The resulting elastomers showed good thermal stabilities and fair mechanical properties after aging at 280℃ and 300℃ for 24 hours respectively.Compounds Ⅰ, Ⅱ were used as crosslinking agents for hardening of room temperature vulcanizable silicone rubber. The resulting elastomer had good heat resistance also.Two kinds of heat resistant silicone paints were prepared from H3BO3 and compounds I or II. They showed good thermo-oxidative stabilities after thermal aging at 500℃ for 6 hours. |
