Abstract

In order to solve the problems that when a matte layer is coated on an aluminum-plastic composite film, the aluminum-plastic composite film has a gray feeling and is not uniform in coating, the invention provides a preparation method of a water-based matte coating. A mixed solution of water, acrylic acid and silicon dioxide is coated on a surface layer, needing matte treatment, of the aluminum-plastic composite film, so that the aluminum-plastic film achieves a matte effect. The method is easy to operate, convenient to manufacture, firm in aluminum plastic film coating and safe and reliable in packaging, and gives people an elegant feeling.

Description

technical field [0001] The invention relates to the field of lithium battery packaging materials, and more specifically, relates to a preparation method of a water-based matte coating. Background technique [0002] At present, lithium-ion battery technology is becoming more and more mature, and it is widely used in 3C electronic products, power batteries, energy storage and other fields, which has a greater demand for lithium battery packaging materials. In the field of lithium battery packaging, there are currently three main packaging methods: cylindrical, square and soft. Cylindrical and square packages are mainly made of aluminum and steel shells, and soft packages are mainly made of aluminum-plastic film. Among the three methods, the market share of the aluminum-plastic film soft bag is increasing due to its advantages of light weight and safety. At present, the aluminum-plastic film used in lithium batteries is divided into dry method and thermal method. The structur...
