Abstract

The invention discloses high-hardness heat radiating paint. The high-hardness heat radiating paint comprises the following raw materials in parts by weight: 90 to 95 parts of ultra high molecular weight polyethylene, 2 to 4 parts of aluminium silicate fibers, 1 to 2 parts of tungsten carbide, 0.3 to 1 part of imarcaptoacetate dioctyltin, 0.4 to 1 part of acetyl tributyl citrate, 2 to 3 parts of calcium aluminate, 5 to 8 parts of talcum powder, 1 to 2 parts of 1-ethoxy-2-oil-base imidazoline, 0.5 to 1 part of lead acetate, 1 to 2 parts of cetyl trimethyl ammonium bromide, 2 to 4 parts of hollow glass beads, 1 to 2 parts of disodium octaborate tetrahydrate, 4 to 6 parts of barium stearate and 7 to 13 parts of modified additive. The raw materials such as tungsten carbide are added to the powder paint, so that the surface hardness of a coating is improved, the mechanical properties such as the impact resistance can be improved, and the heat radiating performance of the coating can be enhanced by adding the hollow glass beads.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a high-hardness heat dissipation 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 high-hardness heat-dissipating coating. [0005] The present invention is achieved through the foll...
