Abstract
The invention provides a treatment process of a coating on the surface of an aluminum foil, which comprises the following steps: preparing a hydrophilic coating: aqueous acrylic acid, ethanolamine, ethylene glycol monobutyl ether; putting the weighed raw materials into a first reaction kettle for fully stirring to obtain a hydrophilic coating; preparing a weather-resistant coating: epoxy resin, polybutadiene resin, tartaric acid, polyacrylamide and propylene glycol methyl acetate; putting the weighed raw materials into a second reaction kettle for fully stirring to obtain a weather-resistant coating; bisphenol A epoxy resin, aliphatic amine curing agent, aliphatic amine accelerator, rosin, ethylene glycol, UV-46 and nano iron oxide are selected and put into a third reaction kettle to be stirred. According to the treatment process for the aluminum foil surface coating, the weather-resistant coating is arranged on the surface of the aluminum foil, so that the aluminum foil can be prevented from melting when used in a high-temperature environment, and the ultraviolet-resistant coating is coated on the surface of the weather-resistant coating, so that the situation that materials on the surface of the aluminum foil fall off when the aluminum foil is corroded by ultraviolet rays can be prevented.
Description
Technical Field
The invention relates to the field of aluminum foils, in particular to a treatment process for a coating on the surface of an aluminum foil.
Background
The aluminum foil is a hot stamping material which is directly rolled into a sheet by using metal aluminum, and the hot stamping effect is similar to that of pure silver foil hot stamping.
Currently, aluminum foils are used in a wide range, wherein the aluminum foils are used in aluminum foil installation water tanks for water-proof operations.
The aluminum foil used by the existing installation water tank can be made of durable materials, but the surface of the aluminum foil is corroded due to the fact that acidic liquid is easily dropped from the installation water tank when the aluminum foil is used, and the smearing material can be directly smeared when the existing aluminum foil is processed, so that the situation that the aluminum foil is easily smeared and is not uniformly stuck between the materials is caused when the aluminum foil is used.
Therefore, it is necessary to provide a surface coating treatment process for aluminum foil to solve the above technical problems.
Disclosure of Invention
The invention provides a treatment process for a surface coating of an aluminum foil, which solves the problems that the existing aluminum foil is easily corroded by acidic liquid when used in a mounting water tank, and the later use is influenced because a coating material is difficult to uniformly coat on the surface of the processed aluminum foil.
In order to solve the technical problem, the invention provides a treatment process of an aluminum foil surface coating, which comprises the following steps:

mixing the second raw materials: putting the weighed raw materials into a second reaction kettle for fully stirring to obtain a weather-resistant coating;
s3, selecting bisphenol A epoxy resin, an aliphatic amine curing agent, an aliphatic amine accelerator, rosin, ethylene glycol, UV-46 and nano iron oxide, putting into a third reaction kettle, stirring, adding titanium dioxide, a defoaming agent and a hydrophobic agent, and stirring to obtain an ultraviolet-resistant coating;
