Definitions
- the invention relates to moldings containing barrier films which are back-molded with a polymer material.
- Barrier layers for example made of ethylene vinyl alcohol, integrated into the layer composite by a coextrusion process.
- these moldings still have considerable emissions.
- this method has the disadvantage that the inside of the container for receiving connection elements and functional parts is difficult to access, as is the long cooling time due to the only one-sided intensively possible cooling. Due to the process, blow molding and undercuts are not possible for blow molding. A targeted setting of a wall thickness curve is only possible to a limited extent via the preform wall thickness or the inflation ratio.
- An alternative is to use a second skin that encloses the tank and carries adsorbents on the inside, which serve as spacers.
- a second skin that encloses the tank and carries adsorbents on the inside, which serve as spacers.
- the space between the tank and the outer casing is flushed by air drawn in by the engine (DE-A 41 42 016).
- the disadvantage is the high technical outlay and the need to use adsorbents.
- the object of the invention is a method that can be produced by this method
- the molded articles guaranteeing a reduced emission, in particular of hydrocarbons and of substances contained in plastics, and moreover do not have the mechanical / technical disadvantages shown above.
- this object was achieved by injecting barrier films with polymer materials.
- the application relates to a method and a molded body produced by such a method, in which emissions from plastics are significantly reduced by injecting barrier films.
- the barrier films used can be multi-layered and can also be preformed before back injection.
- Injection molding is a process in which such a film composite is placed in an injection mold and then a polymeric material is injected into the mold. The preforming of the film avoids excessive overstretching in the injection mold, which could impair the barrier properties. Conventional cold or hot forming processes can be used for forming. The film is then cut and placed in the injection mold.
- Injection molding of textiles is a well-known process in the area of automotive interior parts.
- Injection molding of foils for the production of covers and switches for operating the air conditioning system in the car, as well as housings or covers for electrical devices, has recently been used more and more.
- the films made of PC, PMMA or ABS used are usually printed on the front or painted.
- the foils are often preformed before back injection to avoid overstretching.
- a decorated film is generally shaped and trimmed.
- the film preform is then placed in the injection mold and back-injected with a polymer.
- EP-B 0371 425 describes a process for producing deep-drawn plastic
- Molded parts are described in which a film material is deformed under defined conditions (pressure, time, temperature) and, if necessary, back-injected with a plastic compound.
- the films according to the invention described as barrier films can be single-layer films or multilayer composite films which reduce emissions. These are preferably produced using a lamination or coating process or a coextrusion process.
- the films used or even individual film layers can have been stretched monoaxially or biaxially.
- Polymeric materials can be used as the film material.
- the film material can contain both thermoplastic and thermoset polymers.
- Foil composites containing metallic layers are preferred. Foil composites are particularly preferred in which the metallic layers are present either as a single layer or as a vapor-deposited or vacuum-coated carrier film. These can in particular be aluminum or silicon oxide layers or consist of aluminum oxide or silicon oxide layers which are vapor-deposited or vacuum-coated on carrier layers.
- the film composite can contain carrier films and layers with special barrier properties, as well as layers for connecting individual layers, such as adhesion promoter layers and primers.
- Layers containing polyamide, in particular polyamide 6, polyester, in particular polyethylene terephthalate, polybutylene terephthalate, polycarbonate, thermoplastic polyurethanes, polyolefins such as polyethylene and polypropylene, polyimides, polystyrene, polyacrylate, PMMA are particularly suitable as thermoplastic carrier films.
- thermosetting carrier layers containing plastics made of UF (urea-formaldehyde resin), PF (phenol-formaldehyde resin) or also EP (epoxy resin) are suitable as thermosetting carrier layers.
- Polymeric barrier layers containing halogens are also preferred.
- Vinyl polymers in particular polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC or VC / VDC copolymers) and polytetrafluoroethylene (PTFE) and mixtures thereof, are particularly preferred here.
- Polyacrylonitrile (PAN) is also preferred.
- Polyvinyl alcohols (PVOH) and in particular ethyl / vinyl alcohol copolymers (EVOH) are particularly preferred as the polymeric barrier layer.
- Polyvinyl fluoride (PVF) is extremely preferred.
- Polyketones are also preferred.
- a barrier film composite can be produced using known lamination and coating processes. (Ahlhaus, Otto: packaging with plastics; Kunststoff; Vienna: Hanser, 1997) In particular, these include the encapsulation processes, the flat film coextrusion, blown film (co) extrusion and calendering processes.
- the film composite or individual layers of the film composite can be subjected to a surface treatment before, during or after the production.
- a surface treatment is printing processes, vapor deposition processes, painting processes or processes for applying barrier layers, such as fluorination processes or metallization processes or processes for applying
- the polymer material with which the barrier film composite is back-injected can be a thermoplastic or duromer, preferably thermoplastic, and particularly preferably contain polyamide, polyester, polyethylene terephthalate, polybutylene terephthalate, polycarbonate, thermoplastic polyurethane, ABS, styrene polymer, polyolefins such as polyethylene and polypropylene.
- the polymeric material can include fillers and reinforcing materials and conventional additives such as e.g. Processing additives, stabilizer packages and flame retardants included.
- the barrier film is placed in an injection mold and then the polymer material is injected.
- the barrier film can be three-dimensionally formed beforehand.
- the barrier film connects to the injected polymer by back injection.
- the molded article according to the invention has a significant barrier against hydrocarbons z. B. from fuels and fuels as well as additives such. B. stabilizers and plasticizers and also against monomers, di-, trimers, and oligomers, as well as degradation products caused by thermal degradation or by UV radiation.
- the molded body according to the invention thereby prevents
- the moldings according to the invention are produced in an injection molding process in which a possibly preformed barrier film is inserted into the mold and then back-injected with a thermoplastic material.
- the film Before the film is placed in the injection mold, dust and impurities are removed from the film surface by blowing it with ionized air.
- the film is inserted with a handling device in order to achieve reproducible and rational production.
- the film can be held in the injection mold by the geometry of the film. Measures such as electrostatic charging or mechanical fixation are usually necessary to improve the hold of the film in the tool. For long flow paths, the use of needle shut-off nozzles, which in
- the moldings thus produced are used as e.g. Shaped bodies for storing or directing media containing HC, such as operating and fuels, in particular as plastic fuel containers or as shaped bodies in the interior of the motor vehicle, in particular as trim parts, dashboards, shelves
- the application therefore also relates to moldings produced according to the invention, preferably technical hollow bodies, plastic containers, interior parts for motor vehicle interiors, dashboards, storage and particularly preferably plastic fuel containers, expansion tanks, containers, storage and transport containers.
