Embodiment 1
[0031] A method for applying a high-efficiency heat dissipation coating, the method comprising the steps of:
[0032] (1). Clean and dry the metal heat sink surface of electronic equipment with deionized water;
[0033] (2). According to the composition and mass percentage of the material, 10% of ultra-fine graphite, 7% of infrared radiation powder, 35% of binder, 47% of solvent and 1% of dispersant,
[0034] The sum of the distribution ratios of the various components is 100%, and the above-mentioned ultrafine graphite, infrared radiation powder, binding agent, and dispersant
[0035] Mix with a solvent, mix the ingredients, and stir evenly to obtain a slurry;
[0036] Wherein the binder is epoxy modified acrylic resin; the solvent is xylene; the particle size of the infrared radiation powder is 1.3 μm, and the composition and mass percentage are:
[0037] MnO 39.7%
[0038] SiO 2 29.7%
[0039] MgO 9.3%
[0040] K 2 O 5.7%
[0041] CaO 4.7%
[0042] ZnO 4.2%
