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

Embodiment 1

[0016] An antibacterial, anti-corrosion and heat-dissipating coating is characterized in that it is composed of the following raw materials in parts by weight (kg):

[0017] High-density polyethylene 86, N, N'-m-phenylene bismaleimide 1, pentachlorophenol 2, acetyl tributyl citrate 6, dimethyl sulfoxide 2, ammonium dihydrogen phosphate 1, EVA resin 2. 3-glycidyl etheroxypropyl trimethoxysilane 2, ferrous sulfate 0.4, cast stone powder 4, light calcium carbonate 12, modified filler 10;

[0018] The modified filler is composed of the following raw materials in parts by weight:

[0019] Pyrophyllite 30, chromium carbonate 2, butyl hydroxyanisole 0.6, ammonium octamolybdate 2, polytetrafluoroethylene 5, graphite powder 2-3, bone char 2, ricinoleic acid 0.4;

[0020] Calcinate the above-mentioned pyrophyllite at 600°C for 2 hours, mix and ball-mill it with polytetrafluoroethylene, bone char, and graphite powder for 20 minutes after discharging the material, add ammonium octamolybd...

Abstract

The invention discloses an antibacterial anti-corrosive heat dissipation coating which is prepared from the following raw materials in parts by weight: 80-86 parts of high-density polyethylene, 1-2 parts of N,N'-m-phenylene bismaleimide, 1-2 parts of chlorophenasic acid, 5-6 parts of acetyl tributyl citrate, 1-2 parts of dimethyl sulfoxide, 1-2 parts of ammonium dihydrogen phosphate, 2-3 parts of EVA (Ethylene-Vinyl Acetate) resin, 1-2 parts of 3-glycidyl ether oxy-propyl trimethoxy silane, 0.4-1 part of ferrous sulfate, 2-4 parts of cast stone powder, 7-12 parts of light calcium carbonate and 8-10 parts of a modified filler. Because the raw materials including the chlorophenasic acid and the like are added into the powder coating, the antibacterial and anti-corrosive effects of a finished coating product are greatly improved; the coating disclosed by the invention also has an excellent cohesiveness, a high adhesive force to a base material, a good protectiveness, and a good heat dissipation performance.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to an antibacterial, anti-corrosion 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 antibacterial, anticorrosion and heat dissipation coating. [0005] The prese...
