Nanometer multifunctional composite paint

The invention provides nanometer multifunctional composite paint. The paint is mainly prepared by mixing composite nanometer powder, a dispersant, a coupling agent, a solvent, thermal conducting powder, and common paint; the composite nanometer powder, the dispersant, the coupling agent, the solvent, and the thermal conducting powder are premixed into composite nanometer powder syrup, and then a mechanical method is used for mixing the syrup and the common paint. The multifunctional composite paint has a heat energy-far infrared transforming function, when the composite nanometer powder slurry and the common paint are uniformly mixed, paint with heat radiation is manufactured; when the mixed paint is brushed on housings of illuminating lamps and electronic instruments, and the brushed paint is dried, the coating has the heat energy-far infrared transforming function, heat on the surfaces of the illuminating lamps and electronic instruments is transformed to far infrared ray and radiated to the air, in order t
