The present invention relates to decorative laminates on metal surfaces. More specifically, this paper relates to the synthesis of sandwich panels hpl
by joining core materials impregnated with phenolic resin and metal panels.
Decorative laminates have been widely used in furniture industry and construction. The durability, price and versatility of decorative laminates make them suitable for almost any structural use. For example, decorative laminates are found all over the floor products, furniture and cabinet tops.
The laminate industry is constantly striving to improve the function of decorative laminates. Whether these improvements involve decorative laminate flooring or improved surface properties, they are suitable for cabinet top, furniture, warehouse shelves, signboards, pillar cladding, front panels, push-pull panels, ceilings, residential cabinets, wall panels, decorative veneers and enhanced lighting, or advances in restaurants, food service equipment, and decorative laminate manufacturing make this material available. Equivalent to or superior to the design of substituted materials.
In view of this situation, the metal surface laminates are now manufactured with double-sided tape or common adhesives to connect metal panels to phenolic resin high-pressure cores. In addition to the simple fact that auxiliary steps are required after the pressing and heating steps of laminate layers, the process of using double-sided tape itself is cumbersome and difficult. The result is that metal surface laminates are substantially more expensive than ordinary laminates.
In addition, although the use of double-sided tape provides stability for the final metal surface laminate, the connection between the metal face plate and the core material is easy to detach under certain circumstances. For example, when a metal surface laminate is cut into strips to make the leading edge of the workpiece, double-sided tape is found to fail. Furthermore, when the bending radius is formed and the bending after forming is heated, the failure of the bonded joint is also found.
Therefore, a metal surface sandwich panels
hpl is needed, which allows easy assembly and enhances the bonding between the metal panel and the resin impregnated plate of the rest of the laminate.
