Abstract

The invention discloses a heat dissipating coating for a server cabinet. The heat dissipating coating is prepared from 30-45 parts by weight of phosphoric acrylate, 20-30 parts by weight of ketone-aldehyde resin, 7-11 parts by weight of amino resin, 6-14 parts by weight of epoxy resin, 7-13 parts by weight of modified diatomaceous earth, 3-8 parts by weight of aluminum nitride, 2-5 parts by weightof silica, 3-6 parts by weight of calcium oxide, 2-4 parts by weight of carbon nanotubes, 5-9 parts by weight of graphene oxide, 2-4 parts by weight of calcium stearate, 3-5 parts by weight of propylene glycol, 2-4 parts by weight of tributyl citrate, 1-3 parts by weight of an ultraviolet absorber and 2-3 parts by weight of an antifoaming agent. The heat dissipating coating can effectively reducethe temperature of the surface of the server cabinet, improve the heat dissipation efficiency of the server cabinet, and improve the reliability and service life of the electronic equipment.

Description

technical field [0001] The invention belongs to the technical field of computer server cabinets, and in particular relates to a heat-dissipating coating for server cabinets and a preparation method thereof. Background technique [0002] At present, in the working process of the electronic equipment, improving the heat dissipation efficiency of the electronic equipment is a focus of attention. The performance, reliability and lifetime of electronic equipment is inversely proportional to the temperature of the operating environment. During the working process of electronic equipment, if the large amount of heat generated cannot be dissipated in time, it will affect the normal operation reliability of electronic equipment and shorten the service life of electrical equipment. For this reason, it has become an urgent need to prepare a kind of high-efficiency heat dissipation coating on the surface of electronic equipment. Contents of the invention [0003] The invention provi...
