Embodiment 1

[0016] A kind of nylon dry powder heat-dissipating coating is characterized in that it is made up of the raw material of following parts by weight (kg):

[0017] Nylon TR90 86, 1,4-cyclohexanedimethanol 2, gibbsite 8, cellulose acetate 2, diisopropylethanolamine 1, ferrous sulfate 1, epoxy octyl stearate 4, konjac glucomannan 1. Light calcium carbonate 6, propylene glycol butyl ether 1, modified filler 10;

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

[0019] Pyrophyllite 40, chromium carbonate 2, butyl hydroxyanisole 0.6, ammonium octamolybdate 2, polytetrafluoroethylene 5, graphite powder 2, 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 octamolybdate and butyl hydroxyanisole, stir and heat to 90°C, and keep warm for 16 Minutes...

Abstract

The invention discloses a nylon dry powder heat-radiating coating which is prepared from the following raw materials in parts by weight: 80-86 parts of nylon TR90, 2-3 parts of 1, 4-cyclohexanedimethanol, 6-8 parts of gibbsite, 2-3 parts of acetate fiber, 1-2 parts of diisopropyl ethanol amine, 1-2 parts of ferrous sulfate, 4-7 parts of epoxy ethylhexyl stearate, 1-2 parts of konjac glucomannan, 4-6 parts of light calcium carbonate, 1-2 parts of propanediol butyl ether and 6-10 parts of modified filler. The powder coating disclosed by the invention has good scratching resistance, impact resistance and wear resistance, and is free from solvent, good in anti-aging performance, simple in preparation method and free from environmental pollution.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a nylon dry powder 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 purpose of the present invention is to provide a nylon dry powder heat dissipation coating. [0005] The present invention is achieved through t...
