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 insulating and heat dissipating coating. The insulating and heat dissipating coating consists of the following raw materials in parts by weight: 78-82 parts of ultra-high molecular weight polyethylene 0.7-2 parts of naphthenic oil, 0.1-0.3 part of trially isocyanurate, 3-4 parts of mineral wood fiber, 0.3-0.6 part of dimethyl diisooctyl tin dimercaptoacetate, 6-10 parts of attapulgite, 2-4 parts of jade powder, 1-2 parts of octyl isothiazolinone 6-8 parts of fumarate,0.2-0.4 part of a cross-linking agent TAC, 1-2 parts of copper sulfate, 1-2 parts of sodium metasilicate and 4-7 parts of modifying filler. The powder coating disclosed by the invention is free of toxicity and pollution, resists aging and salt mist, has strong impact resistance and good insulating performance, is safe and reliable, and has strong leak resistance and good heat dissipating effect.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to an insulating and 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 insulating and heat-dissipating coating. [0005] The present invention is achieved through the ...
