Description

Technical Field

[0001] This invention relates to the field of curtain wall decorative panel manufacturing technology, and more specifically, to a method for manufacturing a high-strength assembled curtain wall decorative panel. Background Technology

[0002] Decorative ceiling panels, used in homes and office buildings, are typically made of plastic. However, plastic panels have a relatively simple surface structure and lack aesthetic appeal. Aluminum sheets or foils, on the other hand, can be made into various patterns, offering superior aesthetics such as brushed, coated, and painted aluminum foil. Therefore, most existing decorative ceiling panels use aluminum-plastic composite panels to achieve the desired surface aesthetics and are more suitable for decorative applications.

[0003] However, due to the poor strength of plastic materials, they are prone to deformation during use and have a short service life. They cannot be well applied in places with high decoration requirements, which is not conducive to expanding the market demand for aluminum-plastic composite ceiling panels. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a method for preparing a high-strength assembled curtain wall decorative panel, which improves the strength of the produced panel, prevents the panel from deforming during use, and thus improves the service life of the panel.
