Embodiment 1

[0016] A multi-fiber heat-conducting powder coating is characterized in that it is made up of the following raw materials in parts by weight (kg):

[0017] High-density polyethylene 110, dodecyl dimethyl benzyl ammonium oxide 2, guanidine sulfamate 1, T800 carbon fiber 6, acetate fiber 3, glass fiber 4, bamboo fiber 1, alcohol ester twelve film-forming aids 2, Dioctyl phthalate 5, oxidized polyethylene wax 5, trimethylolpropane 1, modified filler 16;

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

[0019] Pyrophyllite 45, bone char 7, aluminum dihydrogen phosphate 2, light calcium carbonate 2, octylisothiazolinone 0.8, polybutylacrylate 1, silane coupling agent KH560 0.4;

[0020] Calcinate the above-mentioned pyrophyllite at 600°C for 2 hours, mix it with light calcium carbonate and grind it into powder after discharging, and obtain a premix; mix the above-mentioned bone char and aluminum dihydrogen phosphate with ball mill, add p...

Abstract

The invention discloses a multi-fiber heat conduction type powder coating which is prepared from the following raw materials in parts by weight: 100-110 parts of high-density polyethylene, 1-2 parts of dodecyl dimethyl benzyl ammonium oxidation, 1-2 parts of guanidine sulfamate, 6-8 parts of T800 carbon fiber, 2-3 parts of acetate fiber, 2-4 parts of glass fiber, 1-2 parts of bamboo fiber, 2-3 parts of 2,2,4-trimethyl-1,3-pentanediolmono(2-methylpropanoate), 5-7 parts of dioctyl phthalate, 3-5 parts of oxidized polyethylene wax, 1-2 parts of trimethylolpropane and 12-16 parts of modified filling agent. As the fiber raw materials such as carbon fiber in the powder coating disclosed by the invention are good in heat conduction effect, the heat radiation property of the powder coating is improved.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a multi-fiber heat-conducting powder 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 purpose of the present invention is to provide a multi-fiber heat-conducting powder coating. [0005] The present invention is achieved through...
