Fluororesin radiating paint and preparation method thereof

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...

AI Technical Summary

Problems solved by technology

The thermal conductivity of graphite powder is generally 150-300W / (M K), and the silver powder with superior thermal conductivity in metal materials is only 429W / (M K), and the price is expensive, which is of limited help to improve the overall thermal conductivity of the coating.

The thermal conductivity of single-layer graphene is 3080-5150W / (M K), and the thermal conductivity of multi-layer graphene is generally above 1500W / (M K), which is much higher than that of graphite powder and silver powder. The application of heat-dissipating coating additives has not yet been reported
