LED灌封用高折光指数有机硅树脂的制备与性能
Synthesis and properties of high refractive index silicone resin for high power LED encapsulation
摘要
Abstract
Using different difunctional and trifunctional organoalkoxysilane as monomers,we obtained phenyl vinyl silicone resin with high refractive index by solvent-free dehydration condensation copolymerization,and then prepared potting material by curing the silicone resin through hydrosilylation with silicone oil as crosslinking agent. IR,NMR,TGA,UV,hardness tester,universal testing machine and other methods were used to characterize the silicone resin and the cured potting material. Influences of different factors on the synthesis process were investigated and the optical and mechanical properties of the cured potting material were studied. The results showed that the preparation of solvent-free silicone resin required an appropriate catalyst,suitable amount of water and reaction temperature in order to ensure the transparency of the product. The refractive index of the material increased linearly with phenyl content,and the cured product showed the best mechanical properties when the phenyl content was 30% to 40%.关键词
