Problems solved by technology

Nano-silica has a large specific surface area and high specific surface energy. It is easy to agglomerate in the coating to form secondary particles, resulting in a decrease in the performance of strengthening and toughening. At the same time, the hydroxyl groups on the surface also strengthen this phenomenon.

Abstract

The present invention discloses a light-extinction heat-dissipating coating material, which comprises the following raw materials by weight: 1-2 parts of calcium linoleate soap, 1-2 parts of magnesium myristate soap, 12-15 parts of a styrene-maleic anhydride copolymer, 6-10 parts of propargyl alcohol, 90-100 parts of tetrahydrofuran, 4-7 parts of graphene, 16-20 parts of nanometer silica, 0.2-0.3 part of a silane coupling agent KH560, 700-800 parts of dimethylformamide, 4-5 parts of sodium nitride, 0.04-0.05 part of aluminum trichloride, 1.6-2 parts of a 2-3% sodium ascorbate solution, 1.8-2 parts of a 2-3% copper sulfate solution, 160-170 parts of high-density polyethylene, 0.7-2 parts of polyimide, 6-10 parts of diatomite, 0.8-1 part of castor oil polyoxyethylene ether, 3-4 parts of barium stearate, and 1-2 parts of chlorinated paraffin. According to the present invention, the diatomite, the polyimide, the calcium linoleate soap and the like are added, such that the mirror surface reflection effect of the paint film surface light can be reduced and the rough surface can be formed so as to achieve the light extinction effect.

Description

technical field [0001] The invention relates to the technical field of heat dissipation coatings, in particular to a matting heat dissipation coating and a preparation method thereof. Background technique [0002] With the rapid development of modern science and technology, the high frequency and high speed of electronic devices and the density and miniaturization of integrated circuits have greatly increased the total power density and calorific value of electronic devices per unit volume, thus making the cooling of electronic devices more difficult. increasingly prominent. However, the cooling capacity achieved by conventional cooling systems is greatly challenged, especially in the fields of energy, automobiles, air conditioning, agriculture, chemicals, heating, aerospace, microelectronics, information, etc. put forward higher requirements. The heat dissipation paint is a special paint that improves the heat dissipation efficiency of the surface of the object and reduce...
