Definitions
- the present invention relates to a novel heat-resistant Media that acts as a composite intermediate a metal foil and one arranged thereon printable silicone resin layer is formed.
- Composite foils from a metal foil, in particular aluminum foil, and a synthetic resin layer arranged thereon are known.
- a metal foil in particular aluminum foil
- a synthetic resin layer arranged thereon are known.
- the plastic film is a film made of high-pressure polyethylene, Is polyvinyl chloride or polyisobutylene.
- This slide will in civil engineering, especially as a roof covering or as a heat reflecting film for the production of film bags, used.
- DE-OS 27 38 372 is a composite film for closing of food containers known from a there is unannealed aluminum foil on the top a polyester film is laminated.
- Aluminum composite films are also used as label materials, used especially for beverage bottles.
- aluminum foils are known with one resistant to alkalis or other solvents Lacquer layer are coated (DE-OS 30 27 649).
- Lacquer layer are coated (DE-OS 30 27 649).
- Similar Aluminum foil label materials for bottles that have corresponding layers of lacquer are from DE-OS's 29 21 402 and 29 27 511 known.
- Such known aluminum-plastic composite films have primarily the task of protecting against Moisture etc. They have a relatively low heat resistance on.
- the present invention is based on the object To create media that is characterized by a special good heat resistance.
- this object is achieved by a data carrier material containing a metal foil and one arranged thereon printable silicone resin layer solved.
- the data carrier material designed according to the invention draws high heat resistance or temperature resistance out. It has been shown that the material Withstands temperatures up to 550 ° C, which ultimately does not are far below the melting point of the corresponding metal. In this way there are areas of application for the Media material according to the invention, in which relative high temperatures occur, for example in metal processing, where appropriate metal foil tapes with data carriers be provided and for the purpose of evaporation of the Rolling oil residues or to achieve certain crystal structures be subjected to a subsequent annealing process.
- the attached to the metal foil tapes Data carriers pass through here as tags or as stuck-on labels with the corresponding process.
- the one applied to the data carrier material by printing Coding goes through the corresponding temperature process up to 550 ° C and can then be automatically with the known Read and assign acquisition methods such as scanners. As a result, the data applied is checked again the application of high temperatures and are with the known recognition process can be processed digitally.
- metal foils especially stainless steel, Copper and aluminum foils.
- Aluminum is particularly preferred since it's a cheap, easy to process and generally available material.
- a metal foil a foil made of non-annealed aluminum used, because this is compared to a film soft annealed aluminum give handling advantages.
- silicone resin layer For the production of the data carrier material according to the invention this is provided with a silicone resin layer.
- silicone resins can be used, for example Methyl silicones, phenyl silicones, co-condensed silicones.
- silicone combination resins are particularly preferred, such as silicone polyester, silicone epoxides, Silicone alkyds or silicone acrylates. With such Silicone combination resins are copolymers made of low-molecular, hydroxy-functional silicones for example polyesters, alkyl and acrylic resins.
- Such silicone combination resins become, for example so-called silicone enamel, a decorative coating processed for kitchen appliances, etc.
- the silicone resin layer can contain a pigment. It can any pigments are used here if these have a corresponding temperature resistance. Other known additives, for example marking agents, Matting agents (silica) are also suitable if the appropriate temperature resistance is ensured is.
- the silicone resins are preferred on the metal foil applied as varnishes and in particular in organic Solvents solved. Such solvents are known.
- paint aids such as defoamers, leveling agents, etc. can be added.
- the silicone resin layer must be printable be.
- the silicone resin layer both by conventional printing processes, for example Gravure printing, flexographic printing, offset printing, as well as digital Processes, for example thermal transfer printing, can be printed have to be.
- the thickness of the data carrier material according to the invention in principle any thicknesses are suitable which enable it to be used as a data carrier.
- the data carrier material designed according to the invention preferably has a 20 ⁇ m-150 ⁇ m thick metal foil on which there is a silicone resin layer with 4-20 g / m 2 . Particularly good results were achieved with this material thickness.
- the first step was to create a suitable data medium.
- a silicone polyester resin with a solids content of 57-60% and a viscosity according to DIN 53019 of 1000-1400 mPas were diluted with 30 parts of ethyl acetate.
- the mixture was ball milled for 24 hours.
- an aluminum foil was coated with it in such a way that after evaporation of the solvents in a drying cabinet at 150 ° C., an m 2 weight of the lacquer of about 6 g / m 2 remained on the aluminum foil.
- the material so obtained was at 550 ° C for 30 minutes treated in an oven. That by means of a special thermal transfer ribbon printed EAN code was both with a "Touch-down scanner" as well as recognizable with a laser scanner, and the data received could go on digitally are processed.
