Abstract

The invention provides light-cured high-refractive-index organic silicon gel. The light-cured high-refractive-index organic silicon gel is prepared from the following components in parts by weight: 90 parts of sulfydryl silicon resin, 90 parts of vinyl silicone oil, 30 parts of a high-refractive-index acrylate monomer, 3-5 parts of a photoinitiator, 1-3 parts of an organic silicon tackifier and 0.5-1 part of an auxiliary agent. The light-cured organic silica gel with the high refractive index has the advantages of being high in transparency and good in quality.

Description

technical field [0001] The invention relates to the technical field of silicone gel, in particular to a photocurable high-refractive-index silicone gel. Background technique [0002] LED lighting technology has the characteristics of high integration, high-efficiency light output, sensitive response, miniature reliability, energy saving and environmental protection, long life and easy customization, so it is widely used. LED components mainly include chips, gold wires, brackets, packaging and conductive materials. . Among them, the packaging material and packaging technology play a decisive role in its brightness, warm and cold colors, service life, safety and scope of application, and are the key points for LED performance improvement, industrialization and application popularization. [0003] At present, the industrialized silicone gel for LED packaging usually uses liquid polysiloxane as raw material, which is cross-linked by thermally induced hydrosilylation reaction to...
