| titleOfInvention | A kind of soft encapsulation composite and manufacture method and forming method that is easy to cold-punching molding |
| abstract | The invention provides a kind of soft encapsulation composite that is easy to cold-punching molding, it comprises thermoplastic resin film's layer, aluminum foil metal sandwich layer, heat-resisting or printing film layer; Aluminum foil metal sandwich layer is between thermoplastic resin film's layer and heat-resisting or printing film layer; Thermoplastic resin film's layer comprises top layer hot sealing layer and the PUR resin bed mutually compound with aluminum foil metal sandwich layer; Hot sealing layer surface has in recombination process passes through the trickle convex-concave lines of the molded formation of warm-up mill, and the convex-concave degree of depth of this trickle convex-concave lines is 0.5-25 μ m. The present invention is trickle rough and uneven in surface by trickle convex-concave lines, both can in the time of punching press, avoid composite material surface and mould because being close to " bonding " problem forming, can in the time of punching press, make again air can remain in the gap between mould and composite material surface convex-concave lines, thereby significantly reduce the skin-friction coefficient value of composite, help it in cold-punching molding process, to be easy to the demoulding. Forming method when the present invention provides the preparation method of above-mentioned composite simultaneously and used. |
