Abstract

The invention relates to an organic silicon modified epoxy resin optical packaging material composition. The organic silicon modified epoxy resin optical packaging material composition is prepared from the following raw materials in parts by weight: 20 to 30 parts of organic silicon modified epoxy resin A, 30 to 40 parts of organic silicon modified epoxy resin B, 0.01 to 0.04 part of an antioxidant, 50 to 70 parts of organic silicon modified acid anhydride and 0.01 to 0.06 part of a curing accelerator. The epoxy resin optical packaging material can be used for improving the problems of UV (Ultraviolet) resistance, high-temperature yellowing and the like very well, and can meet white-light, blue-light LED (Light Emitting Diode) package and outdoor RGB (Red, Green and Blue) package.

Description

technical field [0001] The invention relates to a packaging material applied to LEDs, in particular to an organic silicon modified epoxy resin optical packaging material and a preparation method thereof. Background technique [0002] Epoxy packaging materials are widely used in the packaging of optical materials due to their excellent mechanical properties, electrical properties, adhesive properties and good airtightness, which can effectively prevent the blackening of the silver plating layer. Aspects (UV resistance) are slightly insufficient, and there are problems such as easy yellowing during use, which affects the service life. Contents of the invention [0003] The present invention uses 20-30 parts of organosilicon-modified epoxy resin A, 30-40 parts of organosilicon-modified epoxy resin B, 0.01-0.06 parts of antioxidant, and 50-70 parts of organosilicon-modified anhydride as raw materials. Then use raw materials containing benzene rings, which have been proven to ...
