Document Type and Number:
WIPO Patent Application WO/2017/028008
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of adhesives, relating to LED packaging silicones, and more particularly to a high-refractive-index LED packaging silicone. A high-refractive-index LED packaging silicone provided by the present invention comprises a component A and a component B, wherein a weight ratio of the component A to the component B is 10:1. The component A comprises the following raw material components in parts by weight: 80-90 parts of a methyl phenyl vinyl silicone resin, 8-18 parts of vinyl dimethyl diphenyl polysiloxane, 0.1-0.3 parts of a platinum-based catalyst, and 1-5 parts of a binder. The component B comprises the following raw material components in parts by weight: 40-60 parts of a methyl phenyl hydrogenated silicone resin, 40-60 parts of hydrogen-terminated diphenyl polysiloxane, and 0.1-0.3 parts of an inhibitor. The high-refractive-index LED packaging silicone in the present invention has the advantageous effects of high hardness, vulcanization resistance, outstanding adhesion, outstanding resistance to cold, heat and impact, etc.
