Imitation aluminum composite membrane

Abstract

The invention discloses an imitation aluminum composite membrane comprising a PET (Polyether) membrane layer, an adhesive layer, an aluminum foil layer and a PVC (Polyvinyl Chloride) membrane layer. The imitation aluminum composite membrane is characterized in that: the PET membrane layer and the PVC membrane layer are adhered to two sides of the aluminum foil layer through the adhesive layer (4). In the other technical scheme, the PET membrane layer is used for replacing the PVC membrane layer. According to the imitation aluminum composite membrane provided by the invention, the metallic luster and the texture of aluminum metal materials are integrally kept; meanwhile, the aluminum foil layer is located between the PET membrane layer and the PVC / PET membrane layer, so that the oxygen gas can be isolated, the oxidization is prevented and the effect of keeping the previous metallic luster of the aluminum foil for a long time is achieved; and the imitation aluminum composite membrane can be further compounded on surfaces of cold-rolled sheets, aluminum sheets, zinc-plated sheets and building materials to have the decorative, protective and beautiful functions; and the composition membrane has the advantages of simple process, convenience for operation and low cost.

Description

technical field [0001] The invention relates to a composite membrane, in particular to an aluminum imitation composite membrane. Background technique [0002] In the current technology, metal plates, especially steel plates and aluminum materials, are more and more widely used in industry and life, such as automobiles, refrigerators, washing machines, kitchen equipment, industrial and civil buildings. During the use of general steel plates, the metal plate is easy to oxidize and corrode. Therefore, it is necessary to carry out anti-corrosion and anti-rust treatment first, such as spraying paint, but the anti-rust and anti-corrosion ability is not strong, and the paint is easy to scratch and fall off, resulting in the damage of the metal plate. The lifespan is reduced, and the appearance of the metal plate is also seriously affected. [0003] In recent years, in the home appliance industry, coatings on the surface of metal plates have gradually emerged to play a protective r...

Problems solved by technology

During the use of general steel plates, the metal plates are easy to oxidize and corrode. Therefore, it is necessary to carry out anti-corrosion and anti-rust treatment, such as spraying paint, but the anti-rust and anti-corrosion ability is not strong, and the paint is easy to scratch and fall off, resulting in the damage of the metal plate. Reduced lifespan, but also seriously affects the appearance of the sheet metal

[0003]In recent years, in the home appliance industry, coatings on the surface of metal plates have gradually emerged to play a protective role. Unfortunately, more colors and patterns are available. At the same time, it also covers the metallic luster and loses the original texture of the metal.
