PI double-sided aluminum plated filmIt is a new type of high heat resistance polymer widely used in aviation, aerospace, machinery, automotive, electronics and other fields. PI double-sided aluminum plated film is a surface decorative material that can be coated with a layer of metallic aluminum on the surface of PI single-sided aluminum plated film, forming a thin film with a metallic appearance. This film has the characteristics of high heat resistance, high corrosion resistance, and high hardness, making it an ideal high-tech material for aviation, aerospace, and other fields.
There are two main methods for preparing PI double-sided aluminum plated film: chemical aluminum plating method and physical aluminum plating method. Chemical aluminum plating method refers to depositing a layer of metallic aluminum on the surface of PI single-sided aluminum plating film. The physical aluminum plating method has higher thermal stability and corrosion resistance, but the price is relatively high. The preparation process of PI double-sided aluminum plated film includes pretreatment, precursor oxidation, chemical plating, and post-treatment steps. Pre treatment includes oil removal, removal of surface oxides and metal salts, etc. Precursor oxidation refers to the process of chemically plating the oxidized PI single-sided aluminum film again to form a thin film with a metallic appearance. Post treatment includes annealing and passivation to improve the corrosion resistance and thermal stability of the aluminum plated film.
PI double-sided aluminum plated film is an ideal high-tech material for aviation, aerospace, machinery, automotive and other fields.
The basic characteristics of PI double-sided aluminum plated film mainly include the following: firstly, it has excellent dielectric properties, which can effectively suppress the propagation of electromagnetic waves; Secondly, it has good high temperature resistance and can withstand environments with high temperatures; Thirdly, it has good pollution resistance and can withstand a certain degree of pollution; Fourthly, it has good reflective performance, which can effectively prevent the reflection of visible light and ultraviolet light; Fifth, it has good wear resistance and can withstand certain mechanical wear.
PI double-sided aluminum plated filmThe preparation process mainly includes steps such as coating polyimide (PI), coating epoxy resin, coating aluminum powder, hot pressing treatment, and surface treatment. Among them, the coating of polyimide (PI) is the basic step in preparing PI double-sided aluminum plated film, which applies the PI film material onto the substrate to form the basic structure of the PI double-sided aluminum plated film; The coating of epoxy resin is to enhance the dielectric properties of PI double-sided aluminum plated film; The coating of aluminum powder is to improve the optical properties of PI double-sided aluminum plated film; Hot pressing treatment and surface treatment are aimed at improving the mechanical and insulation properties of PI double-sided aluminum plated film.
