Definitions
- the present invention relates to a novel heat resistant Data carrier material as a composite between a metal foil and a arranged on this printable silicone resin layer is formed.
- Composite films of a metal foil, in particular aluminum foil, and a resin layer disposed thereon are known.
- an aluminum-plastic composite film described in the the plastic film is a high-pressure polyethylene film, Polyvinyl chloride or polyisobutylene is. This slide will in civil engineering, especially as a roof cover or as a heat-reflecting film for the production of film bags, used.
- From DE-OS 27 38 372 is a composite film for sealing known from food containers that come from a Unglowed aluminum foil is on top of it a polyester film is laminated.
- Aluminum composite films are also used as label materials, especially for drinks bottles used.
- aluminum foils are known with the one resistant to alkalis or other solvents Paint layer are coated (DE-OS 30 27 649).
- Paint layer are coated (DE-OS 30 27 649).
- Similar Aluminum foil label materials for bottles that have corresponding paint layers are from the DE-OS'en 29 21 402 and 29 27 511 known.
- Such known aluminum-plastic composite films have primarily the task of a protective function against Moisture, etc. They have a relatively low heat resistance on.
- a heat resistant data carrier material which consists of a Steel foil is on top of which a printable silicone resin layer is arranged.
- the present invention is based on the object To create data carrier, which is characterized by a particularly good heat resistance distinguishes.
- This object is achieved by a data carrier material containing a metal foil of unannealed aluminum and arranged on this one printable silicone combination resin layer solved.
- the inventively designed data carrier material records by a high heat resistance or temperature resistance out. It has been shown that the material Temperatures up to 550 ° C endures, which ultimately not far below the melting point of the corresponding metal. In this way, there are applications for the Inventive data carrier material in which relative high temperatures occur, for example in metalworking, 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 hang tags or as glued labels with the appropriate process.
- the applied to the data carrier by printing Coding goes through the corresponding temperature process up to 550 ° C and can then be automatically with the known Capture and map capture methods, such as scanners.
- the applied data itself secured the application of high temperatures and are with the known recognition method digitally processable.
- metal foils in particular stainless steel, Copper and aluminum foils.
- Aluminum is especially preferred because it is a cheap, easy to process and commonly available material.
- a metal foil a foil made of unannealed aluminum used, since this is opposite to a slide softened aluminum results in handling advantages.
- silicone resin layer For the preparation of the data carrier material according to the invention this is provided with a silicone resin layer.
- silicone resins are used, for example Methyl silicones, phenyl silicones, co-condensed silicones.
- silicone combination resins such as silicone polyesters, silicone epoxies, Silicon alkyds or silicone acrylates.
- Silicone combination resins are copolymers from low molecular weight, hydroxy-functional silicones with for example, polyesters, alkyl and acrylic resins.
- Such silicone combination resins become, for example, too so-called silicone enamel, a decorative coating for kitchen appliances, etc. processed.
- the silicone resin layer may contain a pigment. It can Here, any pigments are used, if they 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 preferably applied to the metal foil applied as varnishes and in particular in organic Solvents solved. Such solvents are known.
- Known paint assistants such as defoamers, leveling agents, etc., can be added.
- the silicone resin layer must be printable be.
- the silicone resin layer both according to conventional printing methods, for example Gravure printing, flexo printing, offset printing, as well as digital Process, such as thermal transfer printing, printable have to be.
- the thickness of the data carrier material according to the invention in principle any thicknesses are suitable which make it possible to use them as data carriers.
- the data carrier material formed according to the invention preferably has a 20 ⁇ m-150 ⁇ m thick metal foil on which a silicone resin layer with 4-20 g / m 2 is located. With this material thickness particularly good results were achieved.
- a suitable data carrier material was produced.
- 37 parts of a silicone polyester resin having 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 so that after evaporation of the solvent in a drying oven at 150 ° C m 2 weight of the paint of about 6 g / m 2 remained on the aluminum foil.
- the material thus obtained was at 550 ° C for 30 minutes treated in an oven.
- the by means of a special thermal transfer ribbon Printed EAN code was both with a "Touch-down scanner" as well as with a laser scanner recognizable, and the data received could continue digitally are processed.
