Abstract

The invention relates to a heat dispersion resin composition for an LED (Light-emitting Diode) base plate. The heat dispersion resin composition is prepared from epoxy resin A, a metal organic compound MOF and a curing agent. According to the heat dispersion resin composition provided by the invention, with the introduction of the MOF material, resin used in the composition is cured so as to further form an ordered higher order structure. The invention can provide the heat dispersion resin composition with a heat dispersion structure with excellent heat dispersion performance.

Description

technical field [0001] The present invention relates to a heat-dissipating resin composition, in particular to a heat-dissipating resin composition for LED substrates with excellent thermal conductivity and a preparation method thereof. Background technique [0002] Since the birth of Light Emitting Diode (LED for short), full color and high brightness have been realized, and white LEDs produced on the basis of blue / purple LEDs. LED components are used as light sources such as display lights due to their small size, long life, and excellent power saving. They have been widely used in automotive lighting, decorative lighting, mobile phone flashlights, and light source modules for large and medium-sized displays. [0003] When used for such a light source, it is often used to arrange two or more LED elements on a surface-mounted LED module, that is, a base substrate (substrate for LED mounting) made of metal such as aluminum, and place LED elements around each LED element. A ...
