Definitions
- the present invention relates to vacuum insulation panels with improved insulation performance, a gas diffusion-tight plastic film suitable for producing such vacuum insulation panels and the use of such vacuum insulation panels in
- Vacuum insulating panels have found great interest in all areas of thermal insulation as excellent insulation materials, but especially in household refrigeration appliances. They usually outperform rigid polyurethane foam, which is usually used in refrigeration appliances, by more than twice as much Vacuum panels are usually produced in which microporous carrier materials are wrapped with foils and welded in a vacuum. The pressure in a VIP is usually below 1 mbar, because the required insulation performance is only achieved at such low pressures. There are basically two types:
- the disadvantage of the VIP based on a core layer made of microporous precipitated silica is that it is based on a powdery material and the VIP have considerable thickness tolerances and deviations from the planicity, which complicate the installation in the refrigeration devices.
- Plastic foams only have a low gas, especially water vapor, absorption capacity, the gas tightness of the film used is of great importance for the use of these otherwise excellent VIP core materials. speed.
- VIP vacuum insulating panels
- I polyolefin heat seal layer
- layer (V) vapor-coated with aluminum or SiOx or a metal oxide of the 2nd or 3rd main group, essentially made of polyester and / or polyamide and / or polypropylene.
- a VIP according to the invention an oxygen diffusion of significantly less than 0.01 cm 3 / m 2 d bar and a water vapor diffusion of significantly less than 0.02 g / m 2 d can be achieved, so that the durability of the insulating effect of a VIP produced in this way meets the requirements of practice.
- Polyolefin homo- or polyolefin copolymers can be used as the polyolefin heat seal layer (I).
- Linear low density polyethylene (“LLDPE”), polybutylene (“PB”), ethyl vinyl acetate (“EVA”), high density polyethylene (“HDPE”), ionomer (“I”) and mixtures of these substances are preferred.
- LLDPE Linear low density polyethylene
- PB polybutylene
- EVA ethyl vinyl acetate
- HDPE high density polyethylene
- I ionomer
- the thickness of the polyolefin heat seal layer (I) is preferably 20 to 200 ⁇ m, particularly preferably 50 to 100 ⁇ m.
- Reactive adhesives such as two-component polyurethane adhesives in particular
- the thickness of the adhesive or connecting layer (II) is preferably a maximum of 6 ⁇ m, particularly preferably 2 to 6 ⁇ m.
- the gas barrier layer (III) preferably consists essentially of polyvinyl alcohol (“PVOH”), ethylene vinyl alcohol copolymer (“EVOH”) and / or of polyamide or of mixtures of PA and EVOH or, in the case of a multilayer embodiment, of the layered combination of PA and EVOH or of mixtures of PA and EVOH and is preferably stretched at least monoaxially. It is optionally provided with a barrier coating, preferably with an acrylic paint.
- the thickness of the gas barrier layer (III) is preferably 10 to 120 ⁇ m, particularly preferably 10 to 20 ⁇ m in the single-layer embodiment.
- the polyolefin layer (IV) preferably consists essentially of polyethylene, polypropylene or polyethylene copolymers. This is preferred according to the invention
- the layer (V) of polyester and / or polyamide and / or polypropylene layer is preferably vapor-coated in the usual way on the side facing away from the other layers with aluminum, SiOx or a metal oxide of the 2nd or 3rd main group and may not be able to do so vapor-coated side with a barrier coating, preferably with an acrylic paint.
- Layer (V) is preferably a layer consisting essentially of polyester or polypropylene, which is vapor-deposited with aluminum, preferably in a thickness of 30 to 80 nm.
- the thickness of the layer (V) is preferably 10 to 40 ⁇ m, particularly preferably 10 to 20 ⁇ m.
- the at least seven-layer plastic film which is also the subject of the invention, can be provided in one or more layers with customary additives and auxiliaries such as, for example, with lubricants, antiblocking agents and antistatic agents in customary amounts.
- VIP are preferred which use plastic foams as the core layer.
- the plastic foams can be: polyurethane or polystyrene foams. Also suitable are plates which are made from ground and pressed plastic foams, such as. B. be described in EP 0791155 B1.
- microcellular, open-pore foam sheets are preferably used as the core layer.
- ground closed-cell foams which, optionally with the addition of suitable binders, have been pressed into sheets, serve as the core layer for the VIP according to the invention. In this way, the production of VIP according to the invention can be used in the recycling process for old foam.
- the preparation of the VIP is normally done by serving as the core layer microporous plate is placed in a prefabricated from the inventive films bag (polyolefin heat-sealable layer (I) on the inside) and seals the remaining open edge in vacuo at 10 "1 to 1 Torr After venting the vacuum chamber, the VIP according to the invention is obtained.
- the high gas-tightness of the film according to the invention gives the VIP a sufficient lifespan despite the low absorption capacity of the core layer. If a getter is still to be used to ensure the service life, it can be dimensioned accordingly small. If necessary, even the use of small amounts of a water vapor binding substance is sufficient.
- the film according to the invention can also be used only for producing one side of the film bag, the opposite side forming a conventional multilayer film with an Al barrier layer, which preferably has one
- the VIP according to the invention can be widely used as high-performance insulation material in insulation in construction, technical insulation and in particular in refrigeration devices.
- the properties of the multilayer film according to the present invention are determined by the following methods:
- the water vapor permeability of the films is determined in accordance with DIN 53122.

- the film bags are manufactured by three-sided welding of 50 x 50 cm pieces of film. Bags were made from the following materials:
- Symmetrically constructed film bag made of a commercially available metal-free barrier film (Combithen PXX from Wolff Walsrode, see example 1 .e).
- Asymmetrically constructed film bag made from the multilayer film according to the invention described in 2. III and the aluminum-containing multilayer film described in 2.1.
- 1000 g of a PUR foam foam from a refrigerator recycling plant are mixed with 35 g of water and 100 g of a polyisocyanate mixture of diphenylmethane diisocyanates and polyphenyl polymethylene polyisocyanates (Desmodur® VP PU 1520 A20; Bayer AG) with a Lödige ploughshare mixer 2 fabric nozzles mixed evenly.
- a mixture of 400 x 400 mm is formed from this mixture in a mold frame, compacted uniformly and then pressed in a laboratory press under a pressure of 5 bar and a temperature of 120 ° C. for 8 minutes using a time measurement program to 25 mm .
- a porous 25 mm plate with a bulk density of 250 kg / m 3 is obtained .
- the plate was heated to 120 ° C. for about 2 hours in order to remove all volatile constituents.
- the panels produced under 3. were placed in the foil bags produced according to 2.1 to 2. IV, evacuated to 2 x 10 " torr and welded. After ventilation, the corresponding VIP was obtained. It was noticed that the VIP with the film according to the invention had a much smoother surface than those with a thin film.
- the still low water vapor permeability can be determined by measuring the weight gain of the VIP after a storage test.
- the weight gain was determined after a storage period of 1 year and extrapolated to 15 years. It was taken into account that the core layer consisting of the rigid polyurethane foam has a water absorption capacity of about 0.5 to 1% of its own weight and, as a result, the pressure in the panel does not initially increase.
- the weight gain due to the permeability to oxygen, nitrogen and carbon dioxide can be neglected in comparison, since it is in the milligram range.
- the VIPs with thick film preferred according to the invention were to be glued in better and more permanently than those with thin films, such as. B. according to structure 2.1. In the case of the latter, there was no liability between the VIP and the outside covering after the remaining room volume had been foamed.
- the cabinet numbers of the freezers manufactured under 6 were examined as follows: The interior was brought to a temperature which was increased by 30 to 40 ° C. compared to the ambient temperature by means of a controllable electrical heater fitted inside the freezer. After the internal temperature had reached a steady state (usually after 4 days), the electrical heating output and the mean temperature difference between the interior and the surroundings were measured over a period of 24 hours
- Cabinet number Z (in W / ° K) determines the temperature measurement in the interior by a total of 6 thermocouples. The following results were obtained:
Landscapes
- Laminated Bodies (AREA)
- Thermal Insulation (AREA)
- Refrigerator Housings (AREA)
