Abstract

The invention provides a high-temperature-resistant aluminum-plastic composite film. The composite film includes a matte layer, a nylon layer, a first adhesive layer, an aluminum foil layer, a secondadhesive layer and a PP layer which are arranged in sequence from top to bottom; a plurality of hollow glass microbeads are arranged in the matte layer, and the hollow glass microbeads are connected with one another by an adhesive. According to the high-temperature-resistant aluminum-plastic composite film proposed by the invention, the matte layer is additionally arranged on the outer layer of the nylon layer, a filler of the coating is hollow particles, the hollow particles have high-temperature resistance and make the surface of nylon have spherical protrusions, so that a contact area of the coating with a mold during deep drawing molding is reduced, friction is reduced, and deep drawing performance is improved; the product is suitable for all existing aluminum-plastic films, and an operation method of the product is simple and easy to implement, improves the efficiency of battery manufacturers, and improves the product performance of the aluminum-plastic film.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a high-temperature-resistant aluminum-plastic composite film. Background technique [0002] Now aluminum-plastic film is not only used in 3C consumer electronics, but also widely used in power batteries, etc. The reason why nylon is used as the outer material in the prior art is that nylon mainly protects the aluminum foil layer in the middle layer from being scratched, and can Continuous operation without damaging the appearance, as well as internal protection against shocks and vibrations caused by drops, etc. during the use of the battery. Heat sealing time, but followed by the nylon surface is easily damaged and whitened at high temperature. [0003] Therefore, in view of the above problems, it is necessary to develop a high temperature resistant aluminum-plastic composite film. Contents of the invention [0004] The technical problem to be solved by the...
