Abstract

The invention provides a graphene oxide-based waterborne high-efficiency cooling coating and a preparation method thereof. The cooling coating comprises the following components: 20-30 parts of waterborne fluorocarbon emulsion resins, 12-18 parts of waterborne vinyl acetate-ethylene copolymer emulsion resins, 5-14 parts of waterborne acrylic emulsion resins, 3-8 parts of heat-conducting metal powder, 5-15 parts of nano silicon carbide, 2-5 parts of mica, 0.5-1 part of graphene oxide and 9-52.5 parts of water. According to the mutual binding effects of the various components in the cooling coating formula, heat generated by the heat source can uniformly diffuse to graphene on the coating surface by virtue of a thermal conduction structure formed by the graphene and heat-conducting metal powder, and the surface graphene rapidly dissipates the heat in the forms of convection and infrared radiation, so that the effect of greatly reducing the heat source temperature is achieved, and the problems that the electronic products in the market are difficult in heat conduction and dissipation, common cooling coatings are undesirable in cooling effect and the like at present are solved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a graphene oxide-based water-based high-efficiency heat dissipation coating and a preparation method thereof. Background technique [0002] With the rapid development of the electronics industry, modern electronic equipment is increasingly becoming a highly integrated system with high-density assembly, which makes the heat flux density of the product increasingly larger. If the heat dissipation capacity of the product is insufficient, the temperature of components and circuits will rise, which will cause thermal deformation and thermal failure of the equipment, affecting the performance and life of electronic products. In addition, in the fields of metallurgy, petrochemical, ceramics, medicine and other industries, various industrial boilers, power plant boilers, flame furnaces and other furnaces are often involved, and their heat dissipation performance is very important to the...
