Embodiment 1

[0048]The following components by weight ratio, 50% fluororesin, 40% special diluent, 4% electron transfer organic compound, 1% graphene, 1% carbon nanotube, 1% titanium dioxide, 3 % of the curing agent is mixed according to the steps and stirred evenly under the condition of 800-1000 rpm at normal temperature to form the target coating. Degrease and decontaminate the surface of the product equipment that needs to be sprayed with heat-dissipating coatings. Stir the target coating fully and pour it into the spray gun. Set the pressure of the spray gun to 0.4MPa, aim at the target surface, and spray back and forth at a distance of 10-20cm. 2-3 times to make the paint evenly cover the surface of the object. The coating is uniform and glossy, and its thickness can be optimized according to needs. The coating can be cured by natural air drying for 12 hours or baked in an oven for 10 minutes to quickly cure.

Abstract

The invention discloses fluororesin radiating paint and a preparation method thereof. The paint mainly comprises an electron transfer type organic compound, graphene, a carbon nanotube, titanium white, other additives and fluororesin, wherein the fluororesin is a paint brand having the highest comprehensive property at present; the electron transfer type organic compound can greatly enhance the thermal radiation rate of the paint; the graphene and the carbon nanotube can further accelerate thermal conduction; and the electron transfer type organic compound, the carbon nanotube and the graphene finally form a full three-dimensional network distribution of granules (electron transfer type organic compound), wires (carbon nanotube) and planes (graphene) in a fluid. The fluororesin radiating paint disclosed by the invention has high thermal radiation rate, high thermal conductivity and low thermal resistance, can realize radiation cooling, and simultaneously has the effects of self cleaning, acid/alkali resistance and super high insulativity, thereby having high practical value.

Description

technical field [0001] The invention relates to a heat-dissipating paint, in particular to a fluororesin heat-dissipating paint 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 safety of personnel and the reliable operatio...
