Problems solved by technology

[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. Small scope of application

Abstract

The invention discloses an environment-friendly black heat dissipation coating which consists of the following raw materials in parts by weight: 82-90 parts of high-density polyethylene, 3-5 parts of ceramic powder, 0.2-0.4 part of polyethylene glycol octylphenol ether, 0.1-0.3 part of cerium dioxide, 4-6 parts of dibutyl maleate, 1-2 parts of ammonium molybdate, 1-2 parts of ethyl naphthol, 10-14 parts of nano bauxite, 1-2 parts of antimony trioxide, 1-2 parts of potassium hydrogen sulfate, 2-4 parts of calcium aluminate, 1-2 parts of polybenzimidazole, 2-3 parts of carbon black, 1-2 parts of iron oxide black and 5-7 parts of modified filler. The powder coating disclosed by the invention has the advantages of strong adhesion, stripping resistance, long service life, stable performance, no toxicity and good heat dissipation property.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to an environment-friendly black heat-dissipating coating. 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 an environment-friendly black heat-dissipating paint. [0005] The present invention is...
