Abstract

The invention discloses a spherical graphite coating. The spherical graphite coating is prepared from the following raw materials in parts by mass: 60-65 parts of spherical graphite, 5-10 parts of flake graphite, 0.5-5 parts of a coalescing agent, 0.5-5 parts of a cosolvent, 0.5-3 parts of a dispersing agent, 0.1-1 part of an de-foaming agent, 0.1-3 parts of a thickener, 0-1 part of a pH adjusting agent, 0-2 parts of an anti-mildew agent, 0-1 part of a preservative, 0-2 parts of a flatting agent and 35-72 parts of waterborne acrylic emulsion. The spherical graphite coating disclosed by the invention has the advantages of excellent adhesion force and good water resistance; by coating surfaces of electronic products with the spherical graphite coating, the heat dissipation of the electronic products can be accelerated and the temperatures of the electronic products can be effectively decreased; the coating method is simple and convenient and is completely identical to that of an ordinary coating.

Description

technical field

[0001] The invention relates to a coating, in particular to a spherical graphite coating for reducing the surface temperature of electronic products, and the coating method is simple and convenient. Background technique

[0002] With the development of coatings applied to electronic products and the demands of market competition, coatings have gradually changed from the earliest low-performance single-function to today's high-performance multi-function. Faced with the increasing concern of various electronic product manufacturers in the market for heat dissipation performance requirements. Traditional heat dissipation materials are mainly used in product heating components. Most of the heat-dissipating coatings applied to product casings are organic materials. The application of organic materials is not only harmful to human health, but also aging during use. Contents of the invention

[0003] The spherical graphite coating provided by the invention has e...
