METAL COMPOSITE FILM AND ELECTROCHEMICAL APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240025151 titled 'METAL COMPOSITE FILM AND ELECTROCHEMICAL APPARATUS

Simplified Explanation

The present disclosure is about a metal composite film used in aluminum-plastic film production. The film consists of an outer substrate resin layer, an intermediate metal layer, and a heat-fusible resin layer. An anti-corrosion layer is formed on the side of the intermediate metal layer that is in contact with the heat-fusible resin layer. The anti-corrosion layer is made of an anti-corrosion solution, which can be applied through coating or heat treatment. The components of the anti-corrosion solution include a trivalent chromium compound, an inorganic acid, and an organic resin. Optionally, the solution may also contain a titanate and a fluoride.

• The metal composite film is made up of three layers: outer substrate resin, intermediate metal, and heat-fusible resin.
• An anti-corrosion layer is applied to the side of the intermediate metal layer that is in contact with the heat-fusible resin layer.
• The anti-corrosion layer is formed using an anti-corrosion solution, which includes a trivalent chromium compound, an inorganic acid, and an organic resin.
• Additional components such as a titanate and a fluoride may be included in the anti-corrosion solution.
• The use of this specific anti-corrosion solution improves the initial peel strength of the intermediate metal layer and the heat-fusible resin layer.

Potential applications of this technology:

• Aluminum-plastic film production
• Packaging industry
• Electronics industry

Problems solved by this technology:

• Corrosion of the metal layer in the film
• Weak initial peel strength between the metal layer and the resin layers

Benefits of this technology:

• Improved corrosion resistance
• Enhanced initial peel strength
• Longer lifespan of the metal composite film

Original Abstract Submitted

the present disclosure relates to the technical field of aluminum-plastic film production and discloses a metal composite film comprising an outer substrate resin layer, an intermediate metal layer and a heat-fusible resin layer; an anti-corrosion layer is formed on a side of the intermediate metal layer, the side being in contact with the heat-fusible resin layer; the anti-corrosion layer is formed of an anti-corrosion solution by coating or heat treatment; the components of the anti-corrosion solution include a trivalent chromium compound, an inorganic acid and an organic resin; the components of the anti-corrosion solution may further include a titanate; the components of the anti-corrosion solution may further include a fluoride. the use of the formula for the anti-corrosion solution within the range defined above in the present disclosure can significantly improve the initial peel strength of the intermediate metal layer and the heat-fusible resin layer of the metal composite film.
