Definitions

  • the present invention relates to a vacuum insulation panel according to the preamble of claim 1 and a manufacturing method thereof.
  • vacuum insulation panels are known in practice. They are thermally and acoustically highly insulating and are therefore used e.g. used as Dämmpaneele.
  • the known vacuum insulation panels consist of a core of an open-pore material, such as a pressure-resistant foam and sealing outer layers or skins.
  • the previously known vacuum insulation panels have the disadvantage, inter alia, that the vacuum is lost even with a slight damage to the outer skin. If, for example, a hole penetrating the cover layers is drilled in the panel, the core draws air and the insulation effect is reduced or significantly worsened.
  • Another disadvantage is that the known vacuum insulation panels can not be reworked, but from the outset in the production in the factory before the evacuation of the core already have the form in which they are subsequently installed or otherwise used. Subsequent reworking is not possible without loss or drastic deterioration of the insulation properties.
  • the mechanical strength of the known vacuum insulation panels is inadequate for many applications. These vacuum insulation panels can not be used as load-bearing elements, but serve only for isolation.
  • the present invention aims to provide a reworkable vacuum insulation panel, and achieves this object with a vacuum insulation panel according to claim 1 and a manufacturing method for a vacuum insulation panel according to claim 18.
  • a vacuum insulation panel is thus provided with a core with cavities and the core to the environment towards tight cover layers, the cavities of the core are formed by tightly sealed against each other chambers, which extend together with their partitions from one cover to another cover layer ,
  • Such a vacuum insulation panel according to the invention has numerous advantages. It can serve both as a high insulation panel, which can be cut to any size, even after evacuation, and which also largely in the partial infringement of the surface gets its function, as well as a static device from the load-bearing walls can be built.
  • the walls or partitions of the chambers form a honeycomb structure. It may further be provided with preference that the honeycomb structure is quadrangular, hexagonal or octagonal, contains circular shapes or is regular or irregular.
  • each cover layer consists of a gas-tight material or is coated with a gas-tight material.
  • each cover layer contains a layer or plate of in particular reinforced epoxy, melamine or phenolic resin or the like in direct contact with the walls or partitions of the chambers, more preferably the reinforcement of the cover layer of glass fiber material, kraft paper or sisal or the like.
  • each cover layer has on its side facing away from the walls or partitions of the chambers side a protective layer, wherein in particular the protective layer may contain a mirrored high barrier or aluminum foil or a high barrier or aluminum coating or the like.
  • each cover layer has a thickness greater than about 0.5 mm, preferably greater than about 1 mm, and most preferably about 1 mm.
  • the walls or partitions of the chambers are made of a gas-tight material or coated with a gas-tight material.
  • the walls or partitions of the chambers contain paper or cellulose, and / or that the walls or intermediate walls of the chambers have a coating with melamine resin, phenolic resin or a melamine resin-phenolic resin derivative, and / or the walls or intermediate walls of the chambers contain kraft or hard paper, in particular with a reinforcement.
  • the walls or intermediate walls of the chambers contain a metallic foil or are vapor-deposited with a metallic layer.
  • the walls or partitions of the chambers based on a cubic meter, a thermal conductivity of less than about 0.3 W / mK, preferably less than about 0.2 W / mK, and more preferably less than about 0.1 W / mK have. Corresponding values are also influenced by the choice of material pairing. Furthermore, the walls or partitions of the chambers may preferably have a thickness of about 0.5 mm.
  • a vacuum of about 98% is preferably present in the chambers, or the chambers contain a heat-insulating gas, such as argon or another noble gas or a corresponding gas mixture.
  • the core is sealed at its free edges between the cover layers with synthetic resin or the like.
  • the invention further relates to a vacuum insulation panel with an evacuated or provided with a insulating gas filling core and the core on both sides sealing, consisting of a gas-tight material or coated with a gas-tight material cover layers.
  • the core consists of a plurality of individual vacuum chambers which are formed by, for example, at right angles to the cover layers extending, in particular regularly arranged, gas-tightly connected to the cover layers walls or partitions, which consist of a gas-tight material or coated with a gas-tight material ,
  • the walls can form a honeycomb pattern or circular tubes in the cross section, or have other geometries.
  • the walls or intermediate walls of the vacuum chambers or generally chambers may in particular consist of a pulp coated with a phenolic resin, alternatively the formation of a metallic foil or of a metal vapor-deposited material or another material having a similar effect.
  • the walls or partitions thus form a plurality of individual vacuum chambers, which are covered on both sides with a cover layer and thus sealed. At least one of the cover layers is applied, for example, under vacuum conditions, so that the chambers are evacuated.
  • the vacuum insulation panel according to the invention can be produced over a large area or endless and then cut to the required size: By cutting is - unlike the previously known from practice vacuum insulation panels - only the insulation effect of the actually cut chambers lost, as this yes compared the adjacent chambers are gas-tight. Even when a hammer, for example, a nail in one of the outer layers, the insulating effect is lost only the respective chamber, but not that of the vacuum insulation panel as a whole.
  • the preferably regularly formed walls and the sandwich construction of the honeycomb structure between the two cover layers give the vacuum insulation panel a high strength, in particular also against forces which are applied to the vacuum insulation panel in the plane of the cover layers.
  • the vacuum insulation panel can be used as a structural element of a building and other applications.
  • the chambers can also be filled, for example, with an open-pored foam, as known from the prior art as a sheet-like continuous core material, or else a closed-cell foam.
  • the honeycomb body can absorb high mechanical loads in conjunction with the cover layers - much higher than wood panels - and yet the honeycomb core weighs only 33 to 60 kg / m 3 , in particular, for example, only about 44 kg / m 3 .
  • An inventive vacuum insulation panel can be used for the following uses (whereby at the same time as to the invention further inventive idea these uses for the design of the vacuum insulation panel is shown):
  • Gates of any kind, such as garage doors, industrial doors, etc.
  • Container construction in general, e.g. Refrigerated containers, sanitary containers, office containers, magazine containers, living containers, etc.
  • Floor coverings of any kind such as Laminate floor, cold storage floor in aluminum, Riffeloptik, etc. false ceilings, house ceilings of any kind
  • Door, gate and window frame insulation of any kind Roller blind boxes of any kind can be manufactured or at least insulated with vacuum insulation panels Heating systems (the system itself can be isolated)
  • Caravan construction Floating house construction Prefabricated construction of any kind Truck trailer construction (cooling trailer construction, etc.)
  • Prefabricated garage construction for example car automatically heats the garage with the last waste heat
  • Paving stone any type of floor covering, does not let the ground cold through
  • inventive vacuum insulation panels are in the field of sound insulation and sound insulation.
  • the invention provides a manufacturing method for such vacuum insulation panels.
  • This method according to the invention for producing a vacuum insulation panel comprises the following steps: a) plates are produced which in cross section have the shape and arrangement of adjacent walls of the half chambers but are substantially longer than the height of the walls of the chambers; then a composite is made by another such plate is placed on a first such plate so that the whole chambers are formed, c) then the plates are connected to each other at their contact points permanently and gas-tight, d) then successively on the top Plate of the composite further plates according to step b) placed and connected to the top plate of the composite according to step c) permanently and gas-tight, e) then the composite is cut transversely to the plates into chamber discs of desired thickness according to the intended chamber height, and f) finally the chamber discs on the open sides of the chambers are permanently and gas-tightly connected to the cover layers.
  • the method further provides that the cover layers are successively connected to the respective honeycomb disc, and that the joining of the second cover layer with the assembly of the chamber disc and the first cover layer under a vacuum, in a vacuum or in a gas atmosphere with a gas takes place, which is intended as a filling for the chambers.
  • the cover layers are connected simultaneously to the respective honeycomb disk, and that the bonding of the cover layers to the chamber disk takes place under reduced pressure, in a vacuum or in a gas atmosphere with a gas which is provided as a filling for the chambers ,
  • honeycomb production has many advantages: it produces thin, about 0.5 mm honeycomb walls, which are highly resilient high thermal load capacity low weight inexpensive production ultra-fast networking (for example, in 6 s) easy production cheap tool prices and much more.
  • the paper is preheated to soften and deform
  • a stamp brings the paper into shape so that in a side press 30 honeycombs or other desired or suitable number can be pressed at once; Preferably, punches drive one after the other into the paper so that it can follow from one side
  • honeycomb welding of the honeycombs is carried out by placing honeycombs with their still uncrosslinked bottoms together and pressing them together with a press so that the honeycomb bottoms merge to form a complete honeycomb; This can be done in a so-called honeycomb welding device in which thus the honeycomb bottoms are welded together.
  • the honeycomb block is created on one side by welding a half honeycomb to the previous one. This is done by dipping an anvil into the last honeycomb and pressing a welding stamp from one side against the anvil. The two not yet networked honeycomb bottoms are fused together. If the anvil consists of a rather filigree stamp, it moves down into a stabilization plate, so that the anvil is held on two sides, in this way e.g. 30 honeycomb floors simultaneously welded together.

  • the vacuum insulation panel 1 will be described later in connection with FIGS. 3 to 8 in the course of an embodiment of a manufacturing process for it together with the respective manufacturing steps explained.
  • the vacuum insulation panels 1 consist of a chamber core 5, which was modeled in the present embodiment honeycombs and therefore may also be referred to as honeycomb core. It is a hexagonal shape is used, which also octagonal and other shapes, including irregular shapes are possible.
  • the chamber core 5 is formed by the walls 4 and thus contains the chambers 3. Such designs and structures are very stable, require little material and are also very light.
  • corresponding plates 7 are pressed and then glued together to form the entire chambers 3, as the representations in Figs. 3 to 6 illustrate, or alternatively welded.
  • the plates produced can also be referred to as half-chamber plates 7 and are placed one on the other in the arrangement shown in FIG. 1 and glued to the fixed and gas-tight connection at their contact points 8, for example, preferably always placed on an existing composite 9, a new plate 7 and then it is glued before the Such a block or composite 9 is cut transversely to the chamber or honeycomb openings 10 so that the height of the chambers 3 and their walls 4 gives the height of the chamber or honeycomb core 5, such as is illustrated by the illustration of FIG. 6.
  • Fig. 6 are also given by way of example only to be understood dimensions.
  • the chamber openings 10 are closed on both sides, each with a cover layer 11 by the cover layers 11 are tightly and firmly mounted on the respective sides of the chamber core 5. This results in many small closed cells or chambers 3, and the height of the chambers 3 together with the thickness of the cover layers 11 gives the thickness of the vacuum insulation panel 1.
  • the two cover layers 11 are successively glued in separate operations with the chamber core 5 and is the glued second cover layer 11 in a particular approximately 98% vacuum. Instead of gluing other types of attachment, such as welding or direct bonding with each other via not or only partially cured materials of the chamber core 5 and / or the cover layers 11 are possible.
  • the material of the cover layers 11 contains a not yet cured resin, so that the curing of the resin happens at any rate during application and bonding of the second cover layer 11 under a vacuum, so that this vacuum is automatically maintained in the individual chambers or honeycomb cells 4 and maintained ,
  • the cover layers 11 are made of a reinforced epoxy resin.
  • Each cover layer 11 is, as the flow chart-like representations of FIGS. 7 and 8 illustrate, introduced in a single production step wet in a mold and cured under vacuum.
  • the walls 4 of the chambers 3 are pressed into the not yet cross-linked cover layers 11, so that when curing the resin of the respective cover layer 11, the walls 4 of the chambers 3 with airtight connect this cover layer 11.
  • the advantage is achieved that in the quasi-combined production and attachment of the cover layers 11 to the core 5, the cover layers 11 are firmly and non-detachably and gas-tightly connected to the wall material of the core 5.
  • the result is a sandwich material with high rigidity, low weight and very low framework.
  • the core 5 with the walls 4 of the chambers 3, ie without cover layers 11, has in special embodiments a density of about 60 kg / m 3 and a scaffold ratio to the cubic meter of 1:17. However, this ratio can also be in the range of 1:33, for example. Such a low framework / space ratio benefits the insulation performance.
  • cover layers 11 other materials can be used, such as a derivative of melamine and phenolic resin, which is a very inexpensive solution. Under certain circumstances, such cover layers 11 separately to connect to the core 5 of the vacuum insulation panel 1, for example by gluing. Also other plastics can be used.
  • the cover layers 11 can also contain reinforcements 12 made of glass mats, kraft paper or sisal or similar materials. A particularly preferred layer thickness of the cover layers 11 is approximately 1 mm.
  • the cover layers 11 are provided on their outer sides, ie the sides, which are remote from the core 5, with a protective film 13, such as in particular an aluminum foil 14.
  • a protective film 13 and in particular an aluminum foil 14 has the advantage that in the production and connection of a cover layer 11 with the chamber walls 4, the corresponding shape, in which ultimately the bonding step takes place, is protected, in particular resin material, contained in the cover layers 11 so that no undesirable adhesions of such resin material can take place in the mold.
  • Such Protective films or layers 13 form an effective diffusion barrier against the ingress of air into the vacuum chambers 3.
  • the further advantage is achieved that it serves with its shiny surface as a reflection barrier for IR radiation, whereby the insulating performance of the vacuum insulation panel 1 is additionally increased.
  • the heat transfer occurs in conventional insulation materials known from practice via the so-called scaffold line, the gas line and the radiation line.
  • the largest portion of the gas line with about 2/3 of the total heat conduction.
  • modern thermal insulation materials are evacuated, whereby the gas line is at least largely eliminated.
  • the radiation line is suppressed via reflective surfaces that reflect IR radiation back.
  • the air is evacuated, whereby the gas line is eliminated.
  • the aluminum foil 14 as a protective film 13
  • IR radiation is prevented via the high-gloss surface.
  • the scaffold line which is calculated from the thermal conductivity of the base material and its mass.
  • the core 5 of the vacuum insulation panel 1 of so-called hard paper has a value of 0.1 - 0.2 W / mK in relation to one cubic meter.
  • the core with the chambers 2 weighs 30 - 60 kg / m 3 , depending on the size of the chambers. This results in the framework proportions based on the cubic meter, as previously mentioned with a ratio of, for example, about 1:17 to about 1:33, which are preferably values.
  • the thermal conductivity of a paper for example, used with the already specified values of 0.1 - 0.2 W / mK causes the values of the Scaffolding line of the vacuum insulation panels 1 of, for example, 0.0058 - 0.0117 W / mK to z. B. 0.0029 - 0.0058 W / mK lie.
  • vacuum insulation panels 1 An essential aspect of vacuum insulation panels 1 is the diffusion of air into evacuated cavities.
  • the vacuum insulation panels 1 are subject to a constant gas pressure, which tries to create a pressure equalization between the atmosphere and the prevailing in the chambers 3 of the vacuum insulation panel 1 vacuum.
  • Vacuum insulation panels known from practice consist of a foam core, a protective fleece and a plastic barrier film, which is usually vapor-deposited with aluminum. Due to its low layer thickness, this barrier film provides only little protection against diffusion. In the case of vacuum insulation panels known from practice, an attempt is made to compensate for this deficiency by means of special barrier films. Another disadvantage of the known vacuum insulation panels is that they consist of only one vacuum chamber, since the foam core is made of an open-cell foam, and thus a pressure equalization on the entire system acts simultaneously.
  • the particular construction of the vacuum insulation panels 1 according to the present invention has very significant advantages here, since the pressure generally only on the outer lying on the edge 15 between the outer layers 11 chambers 3 or honeycomb loads. Since the individual chambers 3 are sealed against each other, a pressure equalization would first have to take place in these outer chambers 3 and then spread successively inwards.
  • This advantage is achieved just by the fact that the core 5 of the vacuum insulation panels 1 according to the invention consists of many individual chambers 4, in which only successively from the edge 15 between the cover layers 11 air can penetrate.
  • the core 5 is provided at its free edges 15 between the cover layers 11 with synthetic resin, such as resin putty, or the like is sealed diffusion-tight.

  • the material of the walls 4 or partitions of the chambers 3, or in other words the core 5, consists in the embodiment shown of kraft paper, which is coated with a melamine-phenolic resin derivative.
  • the resin cures under a pressure of 30 bar and a temperature of 185 0 C in about 6 s.
  • the advantage of the resin is that the crosslinking takes place only as long as energy is supplied. So the resin can be dried without curing completely.
  • the wall material is delivered ready for further processing and, in contrast to other resin systems, is dry and only reacts under pressure and heat to cure.
  • the cross-linking process is complete within approx. 6 s. A subsequent outgassing no longer takes place.
  • Another advantage of this Materials is that it is inexpensive and can be stored as a raw material without problems over a long period of time.
  • the walls 4 of the chambers 3 are about 0.5 mm thick, and have dimensions of 10 mm, resulting in a material length of 49.6 mm per chamber 3 for the walls 4 results. These values are to be understood as examples and may vary depending on the design and requirements.
  • the material is preferably preformed.
