[0024] Example
[0025] The preparation method is as follows:
[0026] (1) Weigh the components of the formula ratio, and then first add the carbon nanotubes to ethanol at a temperature of 50-80°C, and stir evenly;
[0027] (2) Then add the inorganic colloidal particles to the epoxy resin and methyl methacrylate mixed system and stir evenly;
[0028] (3) Mix the solutions of step (1) and step (2), then add the spinel after the electron transition, rare earth element oxides and stabilizers and stir evenly to obtain the coating for heat dissipation on the surface of the LED heat sink.
[0029] The above-mentioned spinel electron radiation has an energy range of 1-1.5MeV and a beam power of 2-20Kw under the conditions of electron irradiation for 0.2-3h to realize electronic transition. Spinel undergoes electronic transition and is ground to a particle size of less than 1000 nm.
