Embodiment 1

[0026] Embodiment 1. Test of heat dissipation effect of heat dissipation coating

[0027] Compositions for making heat-dissipating coatings

[0028] Take 1 kg of toluene, mix 0.2 kg of boron nitride into it, stir for 30 minutes, then add 0.24 kg of epoxy resin, stir for 1 hour, then put it into a ball mill and mix for 4 hours to obtain the present invention. Compositions for making heat-dissipating coatings.

[0029] surface area

[0030] First, take two common aluminum sheets (5cm×5cm×2mm) as the base material of heat dissipation fins, one of them is used as the bare chip of the control group, and the other sheet forms a heat dissipation coating with a thickness of 15mm on its surface. The formation method is to uniformly spray the composition on the surface of an aluminum sheet, and then heat and bake at a temperature at which the solvent toluene can be removed (for example, 80° C.) to obtain the heat dissipation coating of the present invention, and then use the surfac...

Abstract

The invention provides a method for making paint coat which could strengthen the surface rejection of heat, and how to prepare the component of the coat elimination coat. The component of boron nitride and bonding agent formed a surface coating to enhance cooling effect. The paint coat could be used with head cooling metal, sheet, fins, metal backplane, metal or plastic material.

Description

technical field [0001] The invention provides a coating that enhances the heat dissipation effect of the surface. Further, the invention also provides a preparation method of the heat dissipation coating and a composition for making the heat dissipation coating. Background technique [0002] With the miniaturization and precision development of today's electromechanical products, the problem of heat dissipation has become a problem that must be solved for different types of components. The high temperature caused by poor heat dissipation of the components will cause the operation failure and shorten the life of the parts. Therefore, how to improve the heat dissipation efficiency has become the direction of efforts in the development of MEMS technology and materials. [0003] The current heat dissipation mechanism can be divided into two types: active and passive. Active heat dissipation uses gas or liquid medium circulation to dissipate heat. The common active heat dissipati...
