| 摘 要： | 合成了一种新型的含硅环氧单体-二缩水甘油基二甲基硅烷(DGDMS),将其以一定比例加入到普通商用环氧树脂(DER332)中,使用固化剂4,4’-二氨基二苯砜(DDS)共固化制得无卤含硅阻燃环氧树脂,研究探讨该阻燃环氧树脂的性能。结果表明:随着DGDMS含量的增加,空气和氮气中成炭率(700℃)相应得到提高,同时,氧指数由25.5上升至38.0,证明了在环氧树脂分子链中引入DGDMS可大大提高其阻燃性能。 |

| Abstract: | A new silicon-containing epoxy monomer,diglycidyloxydimethyl silane(DGDMS) has been synthesized.By curing DGDMS and DER 332 with 4,4’-diaminodiphenyl sulfone(DDS),several DGDMS/DER 332 mass ratios were used to obtain epoxy system with different silicon-containing.The properties of the mixed epoxy system of DGDMS/DER 332/DDS were investigated and evaluated.The char yield(700 ℃) under air and nitrogen increases remarkably when the silicon content increases.The limited oxygen index(LOI) values enhanced from 25.5 for the commercial epoxy resins to 38.0 for silicon-containing resins,which confirms that incorporating silicon into epoxy resins is able to improve their flame retardancy. |
| Keywords: | Diglycidyloxydimethyl silane Epoxy resins halogen-free flame retardant |
