Abstract

The invention discloses a nano heat-dissipation paint which is prepared from the following raw materials in parts by weight: 94 to 100 parts of high density polyethylene, 1 to 2 parts of nano titanium dioxide, 2 to 3 parts of 2-butoxyethanol, 3 to 4 parts of nano carbon powder, 5 to 6 parts of nano sepiolite powder, 2 to 4 parts of light calcium carbonate, 0.2 to 0.4 part of nickel aminosulfonate, 1 to 2 parts of sodium tripolyphosphate, 0.5 to 1 part of dibutyltin dilaurate, 1 to 2 parts of N,N-dimethyl cyclohexylamine and 6 to 10 parts of modified filling material. The nano heat-dissipation paint contains multiple nano raw materials, so that the compatibility among all the raw materials is enhanced; the heat-dissipation paint is good in fillibility, so that the levelling property and the smoothness on the surface of a painting layer are enhanced. As a result, the nano heat-dissipation paint is good in heat dissipation.

Description

technical field [0001] The invention mainly relates to a powder coating, in particular to a nano 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 kind of nano heat dissipation paint. [0005] The present invention is achieved through the following techni...
