Abstract

The invention relates to the field of thermal radiation technology application, in particular to thermal radiation coating special for the radiator and a preparation method of the coating. The coating is prepared from the compositions of, by weight, 35-45 parts of epoxy resin, 10-18 parts of nanometer silicon carbide, 10-18 parts of nanometer aluminum oxide, 1.5-2.5 parts of carbon nano tube, 25-35 parts of liquid aluminum dihydrogen phosphate, 1.5-2.5 parts of polyoxyethylene polyoxyethylene ether and 20-30 parts of water, a nanometer macromolecule composite material is adopted, the coating has a larger heat radiating area with higher pyroconductivity, the bonding property of the nanometer silicon carbide subjected to metal surface modification treatment with the nanometer aluminum oxide is improved, the thermal radiation efficiency is increased greatly, the radiator surface is coated with the thermal radiation coating so that the radiator has excellent heat dispersion performance, and the wide heat dissipation requirement is met.

Description

technical field [0001] The invention belongs to the application field of heat radiation technology, and in particular relates to a special heat radiation coating for radiators and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, electronic products have entered thousands of households. Radiators are an essential part of many electronic products. It is to avoid excessive waste heat from damaging internal electronic components during the use of electronic products. Experiment The data shows that: the temperature of electronic equipment is reduced by 1 degree from the normal working temperature level, and its failure rate can be reduced by 4%; if it is increased by 10-18 degrees, the failure rate will increase by 100%. According to statistics, the failure rate of electronic equipment is 55%. caused by the temperature exceeding the specified value. However, since the heat sink is severely limited by its material, sha...
