Abstract

The invention discloses an organic silicon material for packaging and a preparation method thereof. The organic silicon material is prepared by mixing components: composite silicon resin, organic silicon silicone oil, a catalyst and a diluent. According to the organic silicon material for packaging, which is disclosed by the invention, by repeatedly testing and combining performance of each material, the best formula is obtained; by adding the composite silicon resin, strength of the packaging material is effectively reinforced. Light transmittance can reach 98 percent, and curing time of the packaging material can be changed by regulating the quantity of the catalyst. When the prepared organic silicon packaging material is applied to a high-power white light LED (Light-Emitting Diode), luminous flux of the white light LED can reach 42.65lm by measurement, so that a good application effect is achieved.

Description

technical field [0001] The invention relates to the field of new materials, in particular to an organic silicon material for packaging and a preparation method thereof. Background technique [0002] With the continuous improvement of power white LED manufacturing technology, its luminous efficiency, brightness and power have been greatly improved. At the same time, LED packaging materials are also facing huge challenges. The use of packaging materials with high refractive index, high UV resistance, heat aging resistance, and low stress can significantly improve the light output power and service life of lighting devices. At present, epoxy resin packaging materials are widely used in China. After curing, epoxy resin has high cross-linking density, large internal stress, high brittleness, and poor impact resistance. Moreover, rising temperature and blue light and ultraviolet radiation will make the epoxy resin Transparency is severely reduced. Under high current conditions, ...
