Heat-dissipating coating and a manufacturing method thereof

A method for manufacturing heat-dissipating coating, comprising:

• a) providing gluey liquid mixed by a compound substance and a first solution, said compound substance being selected from a group consisting of fluorocarbon resin, fluororesin, acrylic acid resin, polyurethane, polyurea resin, unsaturated polyester, epoxide, and mixtures thereof;
• a weight ratio of said first solution to said compound substance ranging from 1:0.6 to 1:1.4;
• b) providing a filler material with porosity structure which is mixed by a filler substance and a second solution, said filler substance being selected from a group consisting of bamboo charcoal, carbon nanotube, graphite, graphene platelets, graphene, carbon spheres, carbon fibers, BN, AlN, mica, SiO2, TiO2, SiC, ZnO, GeO2, and mixtures thereof;
• a weight ratio of the compound substance to said filler substance ranging from 1:0.1 to 1:0.6 and a weight ratio of said second solution to said filler substance ranging from 1:0.3 to 1:0.8;
• c) filtering the gluey liquid and the filler material separately;
• d) mixing the filtered gluey liquid and filler material to produce a heat-dissipating material;
• and
• e) applying the heat-dissipating material produced in step d to a surface of an item and forming a heat-dissipating coating with a thickness between 3 um to 100 um after drying.
