description The invention relates to LED packaging silicone rubber, particularly relates to the high-refractive-index LED packaging silicone rubber, and belongs to the adhesive technical field. The high-refractive-index LED packaging silicone rubber includes a component A and a component B, and the weight ratio of the component A to the component B is 10 to 1. The component A includes the following raw material components in parts by weight: 80-90 parts of methyl phenyl vinyl silicon resin, 8-18 parts of vinyl dimethyl diphenyl polysiloxane, 0.1-0.3 part of a platinum-based catalyst, and 1-5 parts of an adhesive. The component B includes the following raw material components in parts by weight: 40-60 parts of methyl phenyl hydrogen-containing silicon resin, 40-60 parts of hydrogen-terminated diphenyl polysiloxane, and 0.1-0.3 part of an inhibitor. The high-refractive-index LED packaging silicone rubber has the beneficial effects of high hardness, vulcanization resistance, excellent adhesion, excellent hot and cold shock resistant performance and the like.
