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 anti-oxidation heat-dissipation paint. The anti-oxidation heat-dissipation paint consists of the following raw materials in parts by weight: 0.3-1 part of 2,6-di-t-butyl-4-methylphenol, 2-3 parts of aluminum sulfate ammonium, 4-6 parts of butyl benzyl phthalate, 12-15 parts of styrene-maleic anhydride copolymer, 6-10 parts of propargyl alcohol, 90-100 parts of tetrahydrofuran, 4-7 parts of graphene, 16-20 parts of nano silica dioxide, 0.2-0.3 part of a silane coupling agent KH560, 700-800 parts of dimethyl formamide, 4-5 parts of sodium nitride, 0.04-0.05 parts of aluminium trichloride, 1.6-2 parts of a 2-3% sodium ascorbate solution, 1.8-2 parts of a 2-3% copper sulphate solution, 120-130 parts of high-density polyethylene, 2-3 parts of calcium lactate, 0.3-1 part of sodium diacetate, 3-5 parts of sodium potassium silicate, and 0.8-1 part of glyceryl monostearate. The paint provided by the present invention is excellent in oxidation resistance, high in yellowing resistance, not liable to aging, high in peeling resistance, and superior in comprehensive performance.

Description

technical field [0001] The invention relates to the technical field of heat dissipation coatings, in particular to an anti-oxidation 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 an...
