Abstract

The present invention discloses anti-corrosion heat-dissipation paint. The anti-corrosion heat-dissipation paint consists of the following raw materials in parts by weight: 4-6 parts of phthalate ester, 17-20 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 nano silica, 0.2-0.3 parts 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 sulfate solution, 110-120 parts of high density polyethylene, 0.3-1 parts of 8-hydroxyquinoline copper, 1-2 parts of fulvie acid, 2-3 parts of calcium propionate, 0.6-1 parts of zinc pyrithione, and 4-6 parts of polyisobutylene. According to the anti-corrosion heat-dissipation paint, the 8-hydroxyquinoline copper, the fulvie acid, the calcium propionate and the zinc pyrithione are added, so that a good collaborative effect can be achieved, and anti-corrosion and antibacterial effects can be realized, thereby prolonging the protection service life of the paint.

Description

technical field [0001] The invention relates to the technical field of heat-dissipating paint, in particular to an anti-corrosion heat-dissipating paint 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 red...
