Abstract

The invention discloses a synthesis process of viscosified phenyl silicone oil for high-power light-emitting diode (LED) packaging. The synthesis process comprises the following steps of: synthesizing an epoxy end-capping reagent; dehydrating a methyl cyclosiloxane monomer, a methyl vinyl cyclosiloxane monomer and methyl phenyl cyclosiloxane monomer; adding the epoxy end-capping reagent and a catalyst and performing polymerization reaction; and after the reaction, removing the catalyst and performing vacuum devolatilization; and cooling and discharging. Compared with the traditional silicone oil for LED packaging, the viscosified phenyl silicone oil for high-power LED packaging synthesized by the synthesis process has high refractive index and light transmittance, excellent viscosity and excellent room temperature curing property, and can effectively improve the light output and the high temperature resistance of silica gel for LED packaging.
