Problems solved by technology

A POSS modified silicone oil is added to the encapsulation glue. The addition of POSS modified silicone oil not only effectively increases the crosslinking density, but also improves the adhesion to the substrate and heat resistance, but the POSS modified silicone oil has poor compatibility. And the reactivity is low, and the penetration rate of Xunzhi LED encapsulant is low

Description

technical field [0001] The invention belongs to the technical field of LED encapsulation, and in particular relates to a high refraction LED encapsulation adhesive composition resistant to cold and heat shocks and a preparation method thereof. Background technique [0002] Due to the advantages of long life, energy saving, and environmental protection, LED lamps have become a key project for global energy conservation and emission reduction, and incandescent lamps with high energy consumption will gradually withdraw from the stage of history. [0003] At present, LED packaging materials are mainly organic silicon materials, which have the advantages of excellent heat resistance, small internal stress, and no yellowing. With the development of LED packaging technology, the requirements for LED packaging materials are getting higher and higher. The development direction of LED packaging technology mainly includes: high emission efficiency, high reliability, high heat dissipati...
