High-corrosion-resistance high-thermal-conductivity composite aluminum foil and production method thereof

Abstract

The invention discloses a high-corrosion-resistance high-thermal-conductivity composite aluminum foil and a production method thereof, and relates to the surface treatment process of the metal aluminum foil. An anti-corrosion coating is coated outside the aluminum foil, and a hydrophilic layer is wrapped outside the anti-corrosion coating; the anti-corrosion coating is made of graphene, epoxy resin, phenolic resin, isocyanate, a catalyst, a curing agent and a flatting agent; the hydrophilic layer is composed of water-based acrylic resin, ethanolamine, a water-based cosolvent, a water-based adhesive and water. According to the high-corrosion-resistance high-thermal-conductivity composite aluminum foil and the production method thereof, the excellent functions of the graphene are brought into full play, and meanwhile, due to the fact that the materials are few, the content is low, the cost is low, and the product quality is stable and durable; and the technical problem that the paint ofthe oil-water two materials cannot be combined is solved, the product is acid-resistant, alkaline-resistant and high conductivity, the thickness of the copper foil is greatly reduced, but the heat exchange performance is greatly improved.

Description

technical field [0001] The invention relates to a surface treatment process of metal aluminum foil. Background technique [0002] Aluminum foil is used in a variety of industries, and its light, thin, and easy-to-form processing technology has been recognized by various industry personnel. However, when the product is used in some harsh environments, its anti-corrosion performance needs its rigidity requirements. [0003] For this reason, people carry out anti-corrosion processing on the outer surface of the aluminum foil. The industry generally uses water-based acrylic materials to treat the aluminum foil with two layers of hydrophilic and anti-corrosion coatings. It is better, but its anti-corrosion performance still cannot meet the requirements of some special environments, such as offshore drilling platforms, industrial vegetable greenhouses, fermentation environments, nuclear power, etc. Contents of the invention [0004] The object of the present invention is to pr...
