Abstract
The utility model provides a metallic thin-shell element with a plastic binder and the method for producing the same, which comprises an already shaped metallic thin-shell element and one surface thereof has already undergone treatment and is provided with a decorative coating layer, while the other unprocessed surface is provided with a thermoplastic rubber made adhesive layer which is about 400 microns to 500 microns thick. The thermoplastic rubber made adhesive layer is a thermoplastic rubber film composed of benzene block copolymer and carbon-hydrogen petroleum resin. The metallic thin-shell element already having a thermoplastic rubber made adhesive layer is then inserted and fixed into a mold cavity of an injection mold corresponding to the shape of the metallic thin-shell element. With the process of injection molding, a plastic binder is formed on the thermoplastic rubber made adhesive layer through the means of injection molding. The pressure and temperature of the ejected materials during the injection molding of the plastic binder are combined together with the hot melting of the thermoplastic rubber made adhesive layer, which, at the same time, forces some thickness, for instance, ten percent of the thickness of the thermoplastic rubber made adhesive layer, or rather around 40 microns to 50 microns to permeate into fine concave holes on the metallic surface of the metallic thin-shell element.
