摘要： 将甲基苯基二氯硅烷(MePhSiCl2)与二甲基二氯硅烷(Me2SiCl2)、 甲基乙烯基二氯硅烷(MeViSiCl2)和苯基三氯硅烷(PhSiCl3)等共水解后, 在KOH催化下共缩聚, 以三甲基氯硅烷(Me3SiCl)为封端剂, 制备了含有甲基苯基硅氧链节的甲基苯基乙烯基硅树脂, 并利用FTIR, 1H NMR和热重分析(TGA)对产物进行了表征. 将所得甲基苯基乙烯基硅树脂与甲基苯基含氢硅油按一定配比, 在铂络合物催化下硫化成型, 制成发光二极管(LED)封装A/B胶, 用于LED封装. 所得LED封装硅树脂固化后在可见光范围内具有非常高的透光率. 对LED的封装结构进行优化, 获得的LED具有高光效、 高光通量、 窄显色指数和高色温一致性等优点, 可满足功率型LED封装要求.

Abstract: A novel high refractive index and high transparent silicone resin-type material for the packaging of light emitting diode(LED) was introduced. The methylphenyl vinyl silicone resin was synthesized by cohydrolysis of MePhSiCl2 with Me2SiCl2, MeViSiCl2 and PhSiCl3, then by co-condensation polymerization catalyzed by KOH and end-capped with Me3SiCl. Then the silicone material for LED packaging was prepared with the produced methylphenyl vinyl silicone resin, methylphenyl hydrosilicone oil and Karstedt's catalyst. The methylphenyl vinyl silicone resins were characterized by FTIR and 1H NMR. The silicone resins prepared with very high transmittance at range of 400-800 nm after cured. The LED packaged with the silicone resin-type materials exhibited higher luminous flux, higher light efficiency, narrower color-rendering index and higher color-temperature consistency.

Key words: Light emitting diode, Packaging, Methylphenyl vinyl silicone resin, High refractive index
