Abstract

The present invention discloses anti-peeling heat-dissipation paint. The anti-peeling heat-dissipation paintconsists of the following raw materials in parts by weight: 0.6-1 part of didecyldimethylammonium bromide, 2-4 parts of epoxy butyl oleate, 1-2 parts of phytic acid, 2-3 parts of polyvinyl formal, 0.4-1 part of diethanolamine, 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, 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 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, 120-130 parts of high-density polyethylene, 5-7 parts of montmorillonite powder, and 0.7-1 part of calcium oxide. The paint provided by the present invention is strong in adhesion with a base material, high in peeling resistance, not liable to come off and to be destroyed, and is lasting in protective effect.

Description

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