摘要

Abstract

In this work

low-temperature vulcanized

transparent silane modified epoxy resins for LED filament bulb package were prepared. Firstly

transparent silane modified epoxy resins were produced through a controllable sol-gel method using

-(2

3-epoxypropoxy)propytrimethoxysilane and dimethyldiethoxylsilane. The features of the reaction were investigated and the products were characterized in detail. Subsequently

various curing agents were explored to prepare transparent silane modified epoxy resins. The silane modified epoxy resins cured by PEA-230 at a fairly low temperature (40℃/2 h then 60℃/1 h) exhibited excellent thermal stability with a thermal degradation temperature as high as 316.5℃ and adjustable hardness between 40-60 shore A. The application tests showed the materials obtained were good candidates for LED filament bulb package.
