Abstract

The invention discloses a coating for a LED lamp. The coating provided by the invention is applied onto the surface layer of a radiator of the LED lamp. A preparation method for the coating comprisesthe following steps: step 1, adding the dispersion of nano-graphene, nanometer montmorillonite powder, nanometer silicon carbide and nanometer ceramic powder into a conductive electrolyte solution, then adding 0.5 ml of a HCl solution with a concentration of 0.1 M / L, carrying out standing for 10 min, then carrying out ultrasonic treatment at a temperature of 25 + / - 2 DEG C for 30-45 min so as to obtain mixed solution A, adding 0.2ml of a NaOH solution with a concentration of 0.05 M / L, and continuing ultrasonic treatment for 30 min to obtain a mixed solution B; and step 2, pouring the mixed solution B prepared in the step 1 into an electrolytic cell, applying a voltage of 1680-2600V to both ends of the electrolytic cell, controlling the temperature of the electrolytic cell to be 50-55 DEG C, carrying out stirring, and then carrying out a reaction in the electrolytic cell for 150 min so as to obtain the coating on the positive pole of the electrolytic cell. The coating of the invention is improved in heat dissipation performance by nearly 10% compared with conventional heat dissipation coating products of a same kind and has the advantages of better dispersing performance, surface performance, acid and alkali resistance and wear resistance, and prolonged service life.
