    摘要:

    以苯基三甲氧基硅烷、二苯基二甲氧基硅烷、含氢环体和乙烯基双封头为主要原料,制备了具有高透光自交联结构的有机硅树脂,测试了不同Si—H与Si—CHCH2摩尔比对有机硅树脂反应和固化物性能的影响;采用差示扫描量热分析(DSC)、UVVis光谱仪和热重分析仪(TGA)分别研究了其固化过程、透光性能和热分解过程.结果表明:自交联有机硅树脂的固化反应放热较小,且放热峰比较平缓;自交联有机硅树脂固化物具有较佳的透光性,在400~800nm波长范围内的透光率可达100%;自交联有机硅树脂的固化物具有较好的耐热性,最佳成分树脂的起始热分解温度可达3158℃.该自交联有机硅树脂比现有缩合型有机硅材料具有更高的透光性,可用作先进建筑的透光材料和光学器件的封装材料.

    Abstract:

    Highly transparent silicone resin with self crosslinking structure was prepared using phenyltrimethoxysilane, diphenyldimethoxysilane, 1,3,5,7 cyclotetra(methyl siloxane) and bisvinyltetramethyldisiloxane as main raw materials. The effects of different molar ratios of Si—H/Si—CHCH2 on the reaction of silicone resins and the properties of cured products were investigated. The curing process was investigated by differential scanning calorimetry(DSC). The light transmittance was measured by UV Vis spectroscopy. Thermogravimetric analysis(TGA) was used to study the thermal decomposition process. The results show that the self crosslinking silicone resin has a smaller and a slower exothermic peak. The cured self crosslinking silicone resin has better light transmittance up to 100% in the range of 400800nm. The cured product has relatively good heat resistance, the initial thermal decomposition temperature of the cured product could be up to 3158℃. The self crosslinking silicone has higher transparency compared with the existing condensation silicone material,and can be used as advanced architectural translucent materials and optical packaging materials.
