Abstract

The invention discloses a tailing-containing heat-dissipating coating. The coating is prepared from the following raw materials in parts by weight: 90-97 parts of polypropylene, 0.6-1 part of 6-butylated hydroxytoluene, 0.5-1 part of vanadium boride, 1-2 parts of glucose, 2-4 parts of tailing, 1-2 parts of 2-phenylimidazoline, 10-13 parts of sepiolite powder, 0.8-1 part of an antioxidant 1010, 1-2 parts of sodium potassium tartrate, 5-7 parts of glycerol triacetate, 4-6 parts of light calcium carbonate and 10-12 parts of a composite filler. As the tailing serving as a main component in solid industrial waste is added into the raw materials, the production resources are saved, the production cost is reduced, the waste is recycled, the physical property of the powder coating can be enhanced, and the toughness and impact resistance of the finished powder coating are well enhanced. The coating has a good heat dissipating effect, and can be widely applied to coating of LED lamps.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a heat-dissipating coating containing tailings. Background technique [0002] Thermally conductive and heat-dissipating coatings are widely used in fields that require heat dissipation, such as computers, notebook computers, LED lighting, communications, rectifiers, medical and industrial equipment, and are mainly coated on the surface of radiators. [0003] The heat dissipation coatings currently produced are generally used in the heat dissipation of components of electronic products such as CPUs and LED lamps. The requirements for the medium for painting are relatively high, and the adhesion to rough and loose surfaces is not strong, so the use effect is not ideal. The scope of application is small. Contents of the invention [0004] The object of the present invention is to provide a heat dissipation coating containing tailings. [0005] The present invention is achieved thro...
