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 pyrophyllite and bone black blended and modified heat dissipating coating material. The pyrophyllite and bone black blended and modified heat dissipating coating material is prepared from the following raw materials in parts by weight: 93-100 parts of chlorinated polyethylene, 0.1-0.2 part of potassium dihydrogen phosphite, 2-3 parts of calcium fluoride, 1-2 parts of amyl acetate, 4-6 parts of maleic anhydride grafted polypropylene, 5-7 parts of wollastonite powder, 2-4 parts of graphite powder, 1-2 parts of benzotriazole, 2-3 parts of guar gum, 2-3 parts of mannitol, 1-2 parts of sodium lactate, 0.8-1 part of dimethylethanolamine and 7-10 parts of modifying filler. According to the heat dissipating coating material disclosed by the invention, the heat conducting effect of a coating is enhanced through adding the modifying filler and blending and modifying pyrophyllite and bone black, so that the heat dissipating performance is enhanced, and the physical and mechanical properties of the surface of the coating are improved.

Description

Technical field [0001] The invention mainly relates to a powder coating, in particular to a pyrophyllite and bone charcoal blending modified heat dissipation coating. Background technique [0002] Thermal conductive coatings are widely used in computers, notebook computers, LED lighting, communications, rectifiers, medical and industrial equipment and other fields that require heat dissipation, and are mainly coated on the surface of the radiator. [0003] At present, the heat dissipation coatings produced are generally used for the heat dissipation of the components of CPU and other electronic products and the heat dissipation of LED lamps. The requirements for the painting medium are high, and the adhesion to the surface of rough and loose objects is not strong, and the use effect is not ideal. The scope of application is small. Summary of the invention [0004] The purpose of the present invention is to provide a heat dissipation coating modified by blending pyrophyllite and...
