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 a compound radiating coating which is prepared from the following raw materials in parts by weight: 100-105 parts of high density polyethylene, 10-13 parts of E-44 epoxy resin, 1-2 parts of trimethyl hexamethylene diamine, 1-2 parts of powdered aluminum, 0.3-0.5 part of 8-copper hydroxyquinoline, 1-2 parts of phthalic anhydride, 1-2 parts of dodecyl trimethyl ammonium chloride, 3-5 parts of stalactite powder, 5-8 parts of marble powder, 3-5 parts of isooctyl acrylate, 0.3-0.4 parts of potassium zirconium carbonate, 3-4 parts of calcium stearate, 1-2 parts of pine tar and 7-11 parts of modified filler. The radiating coating disclosed by the invention uses polyethylene and epoxy resin mixed as a main material, so that the leveling property and surface resistance of the coating are improved. The coating further has a certain effect on improving the impact resistance, and is excellent in comprehensive performance and strong radiation.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a composite 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 a composite heat dissipation paint. [0005] The present invention is achieved through the following tech...
