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 polyvinyl chloride heat dissipation coating. The polyvinyl chloride heat dissipation coating comprises the following raw materials in parts by weight: 83-90 parts of SG-4 type PVC (polyvinyl chloride) resin, 0.6-1 part of XC-113 trifunctional aziridine crosslinking agent, 1-2 parts of magnesium chloride, 2-3 parts of beta-hydroxyalkylamide, 10-13 parts of mica powder, 1-2 parts of propylene glycol phenyl ether, 3-5 parts of white carbon black, 1-2 parts of hydroxyethyl cellulose, 4-6 parts of triethylene glycol di-2-ethylhexoate, 2-4 parts of aluminum nitride, 4-6 parts of polyvinylidene fluoride, 2-4 parts of acetate fiber, 0.6-1 part of pyromellitic dianhydride, 3-5 parts of benzyl butyl phthalate, 2-4 parts of calcium fluoride and 10-12 parts of modification additives. The powder coating disclosed by the invention has the advantages of good stability of a coat, simplicity in formation of a film, strong weatherability, simple coating process and effect of saving using cost.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a polyvinyl chloride 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 polyvinyl chloride heat-dissipating coating. [0005] The present invention is achieved throug...
