Definitions
- the invention relates to an insulation composite with diffusion-open edge bond.
- a conventional insulation composite with a vapor-permeable insulation needs a diffusion-proof edge bond. This is intended to prevent water vapor from penetrating into the insulation composite and precipitating as condensate and also as ice formation. The consequences of this are microbial growth, as well as optical and mechanical destruction of the insulation composite.
- the diffusion-proof edge bond simultaneously leads to a thermal bridge over the edge bond and thereby to an increased thermal conductivity. Thus, the edge bond has a negative effect on the damage safety and the life of the component.
- WO2012 / 041823 A1 is a microporous, hydrophobic with organosilanes
- Thermal insulation molded body described with a hydrophilic surface whose surface is partially or completely firmly bonded with an open-pored, hydrophilic layer or partially solid with an open-pored, hydrophilic layer or partially solid with an open-pored, hydrophilic layer and partially solid with a non-porous, hydrophilic layer.
- DE-U-202004004187 discloses a vacuum insulation panel made of microporous silica or an airgel which is surrounded on at least one side edge by a frame. The frame is glued to the edges of the vacuum insulation panel.
- WO2014 / 095277 discloses an insulation composite with three insulation layers, namely a centrally arranged vacuum insulation panel and a double-sidedly applied insulation panel
- Thermal insulation panel based on pressed fumed silica.
- the insulation composite is formed by two U-profiles, which enclose the insulation composite with their thighs.
- the insulation composite can be provided on all sides with a U-profile, which adversely affects the thermal conductivity.
- the insulation composite can also be equipped in particular with rectangular plates with only two U-profiles, which are each mounted on opposite sides, which reduces the mechanical stability of the insulation composite.
- the object of the present invention was therefore to provide an insulation composite which remains dimensionally stable and weather-resistant in contact with water.
- the invention relates to an insulation composite with a diffusion-open edge composite, comprising a plurality of gap-free laid consecutive plate-shaped layers comprising
- insulating layer (1) in which a plurality of vacuum insulation panels, preferably with a thermal conductivity of 0.001 - 0.010 W / (m * K),
- the webs (2) each consist of a non-capillary active, vapor-permeable, hydrophobic thermal insulation material with a thermal conductivity of at most 0.025 W / (m * K), preferably 0.010-0.025 W / (m * K) and
- the determination of the thermal conductivity is carried out according to DIN EN 12667.
- diffusion is defined as Sd -? 0.5 m, diffusion-inhibiting than
- the sd value is the product of thickness of
- Non-capillary means that the water absorption coefficient w of the material
- a further embodiment of the invention provides that between the insulating layer (1) and cover layer (3) at least one further insulating layer (5) consisting of a
- Thermal insulation board containing a non-capillary active, vapor-permeable, hydrophobic
- Thermal insulation material is located.
- the thermal insulation material of the webs and the thermal insulation board of the insulating layer (5) may contain, for example, a pyrogenic silica, a precipitated silica, an airgel, a polystyrene, a polyurethane or a polymethyl methacrylate as non-capillary active, diffusion-permeable, hydrophobic thermal insulation material.
- Hydrophobic in the context of the invention is intended to include those materials which have inherently hydrophobic properties, as well as those obtained by a hydrophobic reaction of a hydrophilic material.
- Particularly suitable is a hydrophobized fumed silica.
- the starting material is a hydrophilic, fumed silica which is obtained by flame hydrolysis and is subsequently rendered hydrophobic.
- flame hydrolysis a vaporized or gaseous hydrolyzable silicon halide is reacted with a flame formed by combustion of hydrogen and an oxygen-containing gas.
- the combustion flame provides water for the hydrolysis of the silicon halide and sufficient Heat available for the hydrolysis reaction.
- a silica produced in this way is called fumed silica. It is in the form of aggregates, which because of their
- fumed silicas are ideal thermal insulators because the aggregate structure provides sufficient mechanical stability, minimizes heat transfer through solid state conductivity across the very small contact points within an aggregate, and produces sufficiently high porosity.
- a plate is prepared which contains the hydrophilic, fumed silica. This is subsequently rendered hydrophobic under reduced pressure or overpressure.
- hydrophobing preference is given to using organosilanes which react with the silanol groups of the hydrophilic constituents of the thermal insulation mixture.
- Organosilanes are R n -Si-X 4 -n, RsSi-Y-SiRs, RnSinOn, (CH 3 ) 3-Si- (O-Si (CH 3 ) 2) n-OH,
- the plate further preferably contains IR opacifiers and stabilizing, inorganic fibers, for example glass fibers.
- IR opacifiers are titanium oxides, zirconium oxides, ilmenites, iron titanates, iron oxides, zirconium silicates, silicon carbide, manganese oxides, graphites and / or carbon blacks.
- the particle size of the opacifier is usually between 0, 1 and 25 ⁇ .
- the mean particle diameter d 50 is preferably 1 to 10 ⁇ m, more preferably 2 to 8 ⁇ m.
- the proportion in the thermal insulation panel of hydrophobic silica is preferred
- the insulation composite according to the invention has two cover layers (3) made of a non-capillary-active, diffusion-inhibiting or diffusion-tight material.
- This material can be made of sheet metal, aluminum, stainless steel, polymethylmethacrylate, ceramic or glass, for example.
- the cover layer should have sufficient rigidity to ensure the mechanical stability of the insulation composite.
- the cover layer should have a thickness of at least 0.5 mm.
- the cover layer (4) consists of several layers. It is also possible to provide a capillary-active, diffusion-inhibiting or diffusion-open side on the side facing away from the insulating layer (1) with a non-capillary-active, diffusion-inhibiting or diffusion-tight material on the side facing the insulating material. If this material has sufficient mechanical stability, the non-capillary-active, diffusion-inhibiting or diffusion-tight layer can then be designed as a very thin layer, smaller than 0.5 mm, on the side facing the insulating layer.
- natural stone or exposed concrete may be mentioned as a vapor-permeable, capillary-active layer on the the insulating material side facing are provided with a two-component epoxy resin coating.
- the anchors of the insulation composite according to the invention are preferably made of materials having a thermal conductivity of less than ⁇ 0.035 W / (m * K), for example made of carbon or glass fiber reinforced plastic.
- Another object of the invention is the use of the invention
- Insulation composite in the insulation of a building envelope comprising facades, roofs, ceiling doors, prefabricated facade elements, prefabricated houses, a vehicle shell comprising cars, trucks, aircraft, helicopters, ships, spaceships, of transport and storage containers for temperature-sensitive goods.
- Figure 1 shows a sketch of the insulation composite according to the invention with insulation layer with VIP (1), webs (2), cover layer (3), anchor (4) and optional insulation layer (5).
