Abstract

The invention discloses a self-lubricating hydrophilic aluminum foil and a preparation method thereof. The aluminum foil is provided with a coating, the coating comprises a bottom coating and a surface coating, a coating material forming the bottom coating is a common corrosion-resistant coating material, and the coating material forming the surface coating is a self-lubricating self-crosslinkingcoating material. By means of the self-lubricating aluminum foil developed by the invention, the own lubricity of the coating is increased, and the friction force is reduced; the self-lubricating aluminum foil can reduce the wear rate of a machining mold and has high machinability, and the service life of the mold is prolonged; meanwhile, the self-lubricating aluminum foil has high adaptability tothe mold, the adaptability to high-speed punching machines is improved through the lubrication of the coating and thinning of the aluminum foil, and the self-lubricating aluminum foil is made to be all suitable for high-speed, low-speed and other different punching machines; and the self-lubricating aluminum foil is verified and mass-produced by well-known air conditioning manufacturers at home and abroad already, products are sell well at home and abroad, and the self-lubricating hydrophilic aluminum foil and the preparation method thereof have good economic and social benefits.

Description

Technical field [0001] The present invention relates to the technical field of coating films, and more specifically, to a self-lubricating hydrophilic aluminum foil and a preparation method thereof. Background technique [0002] Hydrophilic aluminum foil is a composite material with aluminum foil as the base material. It has the good heat dissipation of ordinary aluminum foil, and has corrosion resistance and hydrophilicity that ordinary aluminum foil does not have. It is a good heat dissipation material and is used In the radiator of the air conditioner. According to the national standard GB / T3880-2006, aluminum sheets with a thickness of less than 0.2mm are called aluminum foils. Hydrophilic aluminum foil is to treat the base aluminum foil through a special process and coat a hydrophilic coating on its surface. The condensed water will spread quickly on the hydrophilic aluminum foil without condensing into water droplets, thereby increasing the heat exchange area, accelerating...
