Abstract

The invention discloses a high-heat-conductivity heat-radiating nano composite coating which comprises, by weight, 50-60 parts of nano alumina sol, 30-40 parts of high-density polyethylene, 1-3 parts of carbon nano tube, 5-10 parts of titanium phosphate, 10-15 parts of composite filler, 2-3 parts of polyvinylpyrrolidone, 5-9 parts of methyl methacrylate, 2-5 parts of ethyl acetate, 10-15 parts of isopropanol, 5-8 parts of acrylate emulsion, 3-5 parts of nano copper powder and 1-3 parts of triethanolamine. Through reasonable formulation designing, the composite coating has excellent adhesiveness and coating hardness, is efficient in heat radiating after being coated on the surface of an electronic device and is conducive to guiding out heat generated by the electronic device timely and efficiently, so that heat radiating rate is increased, cooling effect is improved, and the composite coating has excellent comprehensive performance and wide market prospect.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a nano-composite coating with high thermal conductivity and heat dissipation. Background technique [0002] With the development of the electronics industry, electronic components continue to develop in the direction of miniaturization and high-speed operation, and the heat generated by components during use is gradually increasing. Therefore, improving or increasing the heat dissipation of electronic components has become a limitation for the development of the electronics industry. One of the technical bottlenecks, the excellent heat dissipation effect is a powerful guarantee to ensure the efficient and accurate operation of electronic products. [0003] Traditional heat dissipation methods include stacking heat sinks on the back of heating electronic components and installing electronic fans, but both methods will greatly increase the volume of electronic products, which cannot meet th...
