Definitions
- the invention relates to binders having barrier properties, to their use for bonding, coating and sealing, to a process for producing composite materials using the binders of the invention having barrier properties and to the use of these composite materials for packaging.
- multilayer systems with separate barrier layers are constructed by combining polyvinylidene chloride (PVDC), ethylene vinyl alcohol (EVOH), and / or aluminum films with polyethylene films, polyester films, and / or polyvinyl chloride films.
- PVDC polyvinylidene chloride
- EVOH ethylene vinyl alcohol
- aluminum films with polyethylene films, polyester films, and / or polyvinyl chloride films.
- These multilayer systems can be constructed either by coextrusion or by bonding separately prepared films.
- packaging films e.g. based on polyethylene terephthalate or biaxially oriented polypropylene, coated with an aluminum and / or silicon oxide layer (in vacuo).
- Another known method uses the surface refinement of the flexible packaging films by coating the films with solvent or water-based polyvinylidene chloride solutions or dispersions. Coating agents and adhesives based on PVDC or EVOH often have insufficient adhesive strength on polyolefin films. Composites of polyolefin films with such adhesives can already be separated by hand. If necessary, a primer must therefore be applied in an upstream process step in order to effect a good adhesion of the surface coating or of the adhesive to the substrate film.
- EP 0906944 A2 discloses solvent-free polyurethane adhesives which have barrier properties to oxygen and moisture. These polyurethane adhesives are obtainable by reacting a linear diol with a linear polyester to form a crystalline hydroxyl-terminated polyester which is reacted with a liquid diisocyanate at an NCO / OH ratio of between about 1 and about 1.1. The polyurethane adhesives thus obtained are used as laminating adhesives.
- the disadvantage is that these types of coating agents often do not have the desired flexibility. Another disadvantage is that long reaction times are required to achieve high barrier properties.
- WO 02/26908 describes laminating adhesive compositions based on polymeric binders, in particular based on one- or two-component polyurethane adhesives, which contain fillers with platelet-like crystallite structure with aspect ratios> 100 in the binder matrix.
- the fillers are for example dispersed in the hydroxyl-containing component of the 2-component adhesive.
- the laminating adhesives show a significant reduction in the oxygen transmission rate. For some applications, however, the pot life may be too short.
- the object of the present invention is to improve the processing and use properties of binders having barrier properties.
- a further object of the invention was the provision of binders with barrier properties, in particular with respect to CO 2 , O 2 , N 2 , water vapor and flavorings, at low temperatures, ie at 20 0 C to 100 0 C, preferably 25 to 80 ° C, particularly preferably 3O 0 C to 6O 0 C, are applicable and have a good initial adhesion.
- the binders should be particularly suitable as laminating adhesives for food packaging. 06835
- the binder When using the binder as a sealant or filler shrinkage during the curing process should be as low as possible. When used for example for coating or as an adhesive, adhesion to surfaces which are difficult to wet is to be improved.
- Another object is the provision of adhesives, sealants and fillers that can be processed quickly.
- A) at least one in the range of 18 ° C to 100 0 C, preferably 2O 0 C to 80 0 C, flowable compound having at least one radiation-curable reactive functional group as component (A);
- component (B) at least one compound having at least one radiation-curable reactive functional group and at least one COOH group as component (B);
- the binder according to the invention has barrier properties to CO 2 , O 2 , N 2 , water vapor and aroma substances.
- the preferred use as a sealant or adhesive reduces the number of production steps involved in making composite materials having barrier properties since the usual additional coatings with polyvinylidene chloride and / or ethylene vinyl alcohol layers or vapor deposition with aluminum layers are no longer required. Due to the absence of a metal layer, the composite materials are more sorted and thus easier to dispose of. In particular, the absence of a metal layer makes it possible to produce transparent film composites with barrier properties.

- Temperatures typical Swiss-St al. are, for example, about 25 ° C to about 75 0 C in the manufacture of flexible packaging films (flexible packaging), about 70 to about 90 ° C in the lamination of glossy films and about 80 to about 130 ° C for applications in the textile industry.
- the coated with the inventive solvent-containing radiation-curable binder with barrier properties film is first in the drying channel at 40 bis 120 0 C dried, then with at least one further film, optionally under pressure, laminated and then irradiated.
- Binder eliminates the drying step.
- the radiation-curable binder according to the invention having barrier properties is obtained by the irradiation and the crosslinking reaction associated therewith
- the binder used according to the invention contains at least one photoinitiator as component (F).
- the described method can be repeated several times, so that
