Abstract

The invention discloses a radiating paint, and a preparation method and an application of the radiating paint. The radiating paint comprises the following components: nano alloy powder, polyvinyl butyral, organic solvent, and cross linking agent. The invention further discloses a preparation method of the radiating paint, and an application of the radiating paint in reducing temperature of electronic products and/or mechanical products, and components of the electronic and/or mechanical products. The radiating paint has high radiance; and within the temperature range from 0 EDG C to 200 DEG C, the emissivity of wavelength of 1micro m is 0.91-0.95, and the emissivity of wavelength of 8micro m-14micro m is 0.92-0.98. The coefficient of heat conductivity of the radiating coat is 143W/m. DEG C, so the paint has excellent heat conducting property. According to the radiation application effect tests, the radiating effect of the radiators is greatly enhanced by the radiating paint, so the electronic products or components of the products are prevented from each danger caused by the excess temperature.

Description

technical field [0001] The invention relates to a coating, in particular to a heat dissipation coating and a preparation method thereof. The invention further relates to the application of the heat dissipation coating in the preparation of heat dissipation products or parts with heat dissipation function, which belongs to the field of preparation and application of heat dissipation coatings. Background technique [0002] Electronic products or some mechanical products will generate a lot of heat during long-term use. If the heat cannot be dissipated in time, the temperature of electronic products or components will be too high. Excessive temperature will cause various hazards. For example, excessive temperature will reduce the resistance value of the resistor and shorten the service life of the capacitor. In addition, the high temperature will cause the performance of the transformer and related insulating materials to decline. Excessive temperature will also cause changes i...
