The invention relates to a reflective composite material (V) comprising a substrate (1) that consists of aluminum, an intermediate layer (2) of an anodically oxidized substrate material, which intermediate layer contacts the substrate (1) with a face (A), and an optically active multi-layer system (3) applied on top of the intermediate layer (2) and consisting of at least three layers, the upper layers (4, 5) being dielectric and/or oxide layers, and the bottom-most layer (6) being a metal layer which consists of silver and forms a reflective layer (6). In order to increase the aging resistance of said material, a diffusion-resistant barrier layer (8) is applied on top of the intermediate layer (2) and under the reflective layer (6), the reflective layer (6) being bonded to the barrier layer (8) via an adhesion promoter layer (9).

A method for integrally molding a metal and a resin and a metal-resin composite structure obtainable by the same are provided. The method comprises forming a nanopore in a surface of a metal sheet; melting a thermoplastic resin on the surface of the metal sheet formed with the nanopore; and injection molding the thermoplastic resin onto the surface of the metal sheet. The thermoplastic resin is a mixture of a main resin and a polyolefin resin, the main resin is a mixture of polyphenylene oxide and a polyamide, and the polyolefin resin has a melting point of about 65° C. to about 105° C.
摘要:
The embodiments described herein relate to anodizing and anodized films. The methods described can be used to form opaque and white anodized films on a substrate. In some embodiments, the methods involve forming anodized films having branched pore structures. The branched pore structure provides a light scattering medium for incident visible light, imparting an opaque and white appearance to the anodized film. In some embodiments, the methods involve infusing metal complex ions within pores of an anodized. Once within the pores, the metal complex ions undergo a chemical change forming metal oxide particles. The metal oxide particles provide a light scattering medium for incident visible light, imparting an opaque and white appearance to the anodized film. In some embodiments, aspects of the methods for creating irregular or branched pores and methods for infusing metal complex ions within pores are combined.
