Abstract_Chinese:\r随着大功率LED 的不断发展，合成高性能LED 封装材料成为目前研究的重点．有机硅树脂逐步替代应用广泛的环氧树脂跻身于高要求的封装领域中，但其仍存在缺陷，对有机硅树脂进行改性可以使其具有更加优异的性能，满足苛刻的LED 封装要求．本文重点研究在分子中引入金刚烷基团对有机硅树脂进行改性．通过1-金刚烷甲醇和3-异氰酸酯基丙基三甲氧基硅烷反应得到1-金刚烷甲醇丙基三甲氧基硅烷-3-氨基甲酸酯．以1-金刚烷甲醇丙基三甲氧基硅烷-3-氨基甲酸酯、三甲氧基乙烯基硅烷和二苯基硅二醇为原料，通过溶胶-凝胶缩合法合成了高折射率的金刚烷基苯基乙烯基硅树脂．通过核磁共振仪和傅里叶变换红外光谱对金刚烷基苯基乙烯基硅树脂的结构进行了表征．采用苯基含氢硅树脂在卡式催化剂的作用下进行固化，制得高折射率的金刚烷改性有机硅封装材料，并对固化后的材料进行透光性、硬度及热稳定性的测试．结果表明，该改性材料具有高折射率(1.57 左右)、高硬度(50 D～59 D)、高透光率(400～800 nm 范围内在80%以上)、优异的耐老化性能(150℃老化48 h 透光率变化很小)和强的热
稳定性，在LED 封装领域具有广阔的应用前景．


Abstract_English:\rWith the development of high-power LED，synthesis of high-performance LED encapsulation materials has become the focus of current research. Silicone resin is gradually replacing the widely used epoxy resin in the highrequirement packaging field, but it still has some defects. The modification of the silicone resin can make the packaging material perform better and meet the demanding requirements of LED encapsulation. The present study focuses on the preparation of high-performance adamantane-modified silicone resin for LED encapsulation by introducing adamantane into the molecule. Here 1-adamantane methanol propyltrimethoxysilane-3-urethane was synthesized via the reaction between 1-adamantane methanol and 3-isocyanatopropyltrimethoxysilane. High-refractive index adamantanebased phenyl vinyl-silicone resins for LED encapsulation were synthesized by the sol-gel condensation of 1-adamantane methanol propyltrimethoxysilane-3-urethane vinyltrimethoxysilane and diphenylsilanediol. The adamantane-based phenyl vinyl-silicone resins were characterized using proton nuclear magnetic resonance and Fourier transform infrared spectroscopy. The high-refractive index adamantane-modified silicone materials for LED encapsu lation were cured by methylphenyl hydrogen containing silicone resin curing agent and Pt Karstedt’s catalyst. Their transparency，hardness，and thermal resistance properties were measured，and the results showed that the modified material exhibited high refractive index (about 1.57)，high hardness (50 D—59 D)，high transparency (above 80% in the range from 400 to 800 nm)，excellent thermal-aging property (small change after thermal aging at 150℃ for 48 h)，and excellent thermal stability，which has broad application prospects in the field of LED encapulation.
