Definitions
- the invention relates to a thermal insulation material according to the preamble of claim 1 and its use.
- Heat is a form of energy that is released in many processes and applications. Such processes take place in motor vehicles, for example, within narrow spatial limits. This leads to temperature increases in bodies that are involved. At the same time, heat-sensitive parts, components or objects must be protected against heat radiation.
- heat shields made of composite materials such as, for example, sheet metal and / or foil, knitted aluminum, mineral fibers, fabric membranes and / or nonwovens are often used for this purpose, as described, for example, in DE 102014014831A or DE 102017007879A.
- Such a shield should therefore be attachable in many places, whereby it should fit into the existing arrangement of the components and into the existing processes. Such a shield should also be retrofittable.
- a secure shield should be made of a self-supporting material that will retain its shape unless it is forced to deform using force.
- the thermal insulation must not contribute to the deterioration of the acoustic performance in the form of structure-borne noise. Because of the narrow spatial conditions, the shielding must ensure the greatest possible temperature difference between the side facing the heat source and the side facing away from the heat source.
- a thermal insulation material consisting of two metallic cover layers and a non-metallic core layer arranged between the cover layers, characterized in that the core layer is viscoelastic and is formed from a silicone-containing material and the cover layers from an aluminum-based one Coated steel flat product are formed.
- a material that contains or essentially consists of polysiloxanes is used as the silicone-containing material.
- a silicone adhesive is used. This contains an alternative, in particular before curing, at least one silicone resin and optionally at least one siloxane rubber and optionally at least one reaction adduct of at least one siloxane rubber and at least one silicone resin.
- a coated steel flat product accordingly consists of a steel substrate, which can be, for example, a steel strip or a steel sheet or a blank produced from a steel sheet, such as a circuit board, and a coating present on at least one side of the steel substrate.
- a steel substrate which can be, for example, a steel strip or a steel sheet or a blank produced from a steel sheet, such as a circuit board, and a coating present on at least one side of the steel substrate.
- both sides of the steel substrate, and hence the cover layers are coated.
- An aluminum-based coating consists of pure aluminum or an aluminum alloy.
- the coating can be applied to the steel substrate in a conventional manner, for example by means of a hot-dip coating process. Other application methods that make it possible to apply a coating are also conceivable.
- a suitable coating for example a corrosion protection coating, is typically at most 50 ⁇ m thick on each side, preferably 0.1 to 50 ⁇ m thick, particularly preferably 1 to 30 ⁇ m thick, in particular 10 to 30 ⁇ m thick per side.
- One embodiment relates to an insulating material that is damping of structure-borne noise.
- the damping is expressed via the so-called loss factor, which is determined according to standard EN ISO 6721.
- the insulating material according to the invention shows a high loss factor over a wide temperature range, in particular a loss factor of 0.01-1.0 measured at 500 Hz at temperatures between -20 ° C and 130 ° C.
- the insulating material preferably has a loss factor of 0.04-0.5, measured at 500 Hz, at temperatures from -20 ° C. to 80 ° C., particularly preferably a loss factor of 0.07-0.3, in particular 0. 1-0.2 at temperatures from 5 ° to 65 ° C.
- One embodiment relates to an insulating material that can be deep-drawn or deep-drawn.
- deep-drawing means that the viscoelastic core layer flows with the cover layers during deep-drawing and that no delamination occurs in the process.
- the insulating material can also be drawn or stretched. This means that during the Erichsen test at room temperature and / or at higher temperatures (e.g. 100 ° C) up to the failure limit of the top layers, no abnormalities, damage and / or macroscopic failure points in the core layer can be adjusted.
- Another embodiment relates to an insulating material that is not flammable and / or heat-resistant.
- a substance is non-combustible if it likes the strict criteria of.
- a substance is heat-resistant in the sense of the invention if it fulfills all requirements at high temperatures.
- the insulation material shows no change in the relevant properties a temperature range from -80 ° C to 250 ° C, especially with brief temperature increases of up to 30 minutes up to 300 ° C and also with shock loads of up to 800 ° C.
- the core layer is non-flammable and can withstand high thermal loads with a permanent load of up to 400 ° C and a shock load of up to 800 ° C.
- the insulating material according to the invention is halogen-free and, owing to its heat resistance, does not release any smoke or toxic fumes even at high temperatures in accordance with IMO 2010 FTP Code book annex 1, Part 2. In addition, there is no unpleasant odor, even under constant load.
- the insulating material has cover layers with coatings which consist of a silicon-containing aluminum alloy.
- Suitable aluminum alloys typically consist of 3 to 15% by weight of Si, preferably 7 to 12% by weight of Si, particularly preferably 9
- transition metals other than Fe 0.4% by weight of transition metals other than Fe, 0.05-2% by weight of alkaline earth metals, preferably 0.1
- alkaline earth metals particularly preferably 0.15-0.4% by weight of alkaline earth metals, and the remainder consisting of aluminum and unavoidable impurities.
- transition metals a distinction is made here between iron and other transition metals, because iron can be present in higher contents than other transition metals. Iron, other transition metals and also elements from the group of alkaline earth metals lead to a dense, thin and opaque oxide layer that reduces the penetration of diffusible hydrogen.
- the following alkaline earth or transition metals have proven to be particularly suitable: Mg, Ca, Sr, Ba, Zr and Ti.
- the metallic cover layers of the insulating material have a thickness of 0.2 to 1.0 mm, in particular 0.2 to 0.75 mm, preferably 0.25 to 0.5 mm and particularly preferably 0, 3 mm.
- the core layer has a thickness of 0.025 to 1.50 mm, in particular 0.02 to 0.5 mm, preferably 0.025 to 0.250 mm, in particular 0.05 to 0.1 mm.
- the invention further relates to an insulating material with a core layer which has deoxidative elements and / or deoxidative alloys which are dispersed in the core layer.
- the core layer is present as a heterogeneous mixture in which the silicone-containing material is present as a dispersion medium for the deoxidative elements and / or deoxidative alloys which are present as particles and are dispersed therein as a disperse phase.
- the deoxidative elements and / or deoxidative alloys are dispersed in the silicone-containing core layer in a proportion of between 0.1 and a maximum of 5% by weight, based on the core layer.
- the proportion of the respective deoxidative elements and / or alloys is limited to a maximum of 5% by weight, in particular to a maximum of 3% by weight and preferably to a maximum of 1.5% by weight.
- the silicone-containing material is briefly temperature-resistant up to 800 ° C. At higher temperatures, as is usually the case with MIG and MAG welding, the silicon in the silicon-containing material decomposes in an oxygen-containing atmosphere due to its high affinity for oxygen in silicon dioxide. The reaction of the silicon with the oxygen significantly reduces the outgassing of the molten metal and the pore formation in the area of the connecting seam.
- the silicon dioxide formed is deposited in the form of a silicate on the joint surface (weld seam surface) and can be removed mechanically if necessary.
- the proportion of deoxidative elements and / or deoxidative alloys is at least 0.1% by weight, in particular at least 0.2% by weight and preferably at least 0.25% by weight.
- Suitable deoxidative elements are, for example, Ca, Mg, Al, Ti, Si, Mn, Cr, Ce, La, Nb, Ta, V and / or Zn in the form of particles, in particular powder and / or flakes.
- ferrosilicon (FeSi), ferrocalcium silicon (FeCa-Si), ferromanganese (FeMn) can be added to the silicon-containing core layer as deoxidative alloys; a combination of 2 or more of the above substances should also be used in the core layer.
- a further embodiment relates to an insulating material which has airgel, in particular aerogels in the form of particles, which in an alternative can, however, still form a closed layer.
- An airgel is defined as an open-line, mesoporous, solid foam that consists of a network of interconnected nanostructures.
- the term airgel does not refer to a specific material composition, but to a geometric arrangement in which a substance can be present. It is therefore a highly porous, dry solid with a pore volume of 95 -99.8%, which form a network of colloidal particles with pore sizes ⁇ 1 to 100 nm.
- Silica, carbon, metal oxide or organic polymers are used as substances. Further description and definition of the term airgel can be found in DE 19537821 (paras.

- the airgel layer is disposed between the top layer and the core layer or on one or both sides of the side of the top layer (s) facing away from the core layer.
- the airgel is preferably dispersed in the core layer or applied as a layer on the side of the insulating material or the cover layer which faces away from the heat source and the core layer.
- the core layer contains fire-retardant additives and / or chemicals.
- the invention further relates to a three-dimensionally shaped insulating material as described above.
- the three-dimensionality in the sense of the invention does not result from the length, width and height of the insulating material, which is based on steel freight products, but from a deformation due to the action of force. Deformation within the meaning of the invention is carried out by a method known to the person skilled in the art, preferably it is selected from the methods selected from the group comprising or consisting of deep drawing, stretch drawing, folding, bending, roller rolling, profile rolling and compression molding, in particular Deep drawing.
- the three-dimensional shape of a deformed insulating material according to the invention thus essentially results from the fact that at least one is considered macroscopically Point of the surface of the insulating material is not in the same plane with the remaining points.
- the insulating material according to the invention is furthermore distinguished by a good specific heat capacity, in particular in a high, wide temperature range.
- the specific heat capacity Cp at 100 ° C is between 0.6 and 1.0; preferably between 0.7 and 0.8; at 250 ° C between 0.75 and 1.0; preferably between 0.8 and 0.85; at 400 ° C between 0.8 and 1.1; preferably 0.9 and 1.0 each J / g / K.

- the temperature difference between the side facing the heat source and the side facing away from the heat source is at least 50 ° C at a temperature of the side facing the heat source of 200 ° C. and at least 250 ° at 500 ° C. on the side facing the heat source C and at 800 ° C on the side facing the heat source at least 350 ° C.
- the silicone-containing core layer is introduced in the form of a film, preferably as an adhesive film, between the metallic cover layers in an alternative.
- the cover layers are preferably laminated with the film at room temperature in a laminating station.
- the core layer is applied in liquid form to one or to both cover layers.
- the coating is carried out by any known process known to the person skilled in the art, preferably it is selected from the processes selected from the group comprising or consisting of roller, knife and nozzle application, coil coating, casting, spin coating, trickling and blowing, preferably roller, Doctor blade and nozzle application as well as coil coating.
- the coated top layer is then combined with a further, optionally also coated top layer to form a sandwich composite, and the core layer is hardened or partially hardened.
- the insulating material can also have three-dimensional deformations, bores and / or functional elements, in particular for fastening.
- the present invention also relates to a method for thermal shielding of a heat-radiating body, comprising or consisting of the following steps:
- thermal shielding there is also acoustic shielding.
- Another object of the present invention is a use of the insulating material according to the invention as a shield, cover, cladding or component, in particular in engines, exhaust systems, passenger cars, commercial vehicles, trucks, special vehicles, buses, buses, track-bound vehicles, ships, inter alia as cabin walls and / or ship cladding, and / or in architectural buildings, that is to say in the building industry, in particular as an outer facade, roof element and / or internal fire protection and / or acoustic walls, structures or ceilings.
- the insulating material is preferably used as a heat protection shield, particularly preferably for shielding particle filters or battery boxes in vehicles. Special requirements must be met, in particular when shielding particle filters. In the event of a crash, the risk of fire increases because there can be direct contact between the shield and the particle filter.
- a heat protection shield made of the insulating material according to the invention fulfills all requirements without damage, in particular in continuous operation. Furthermore, the outer surfaces of the insulating material have corrosion protection due to the coating, as well as one Protection against oils, greases, liquid fuels and / or cleaning agents, such as those used in commercial vehicles and buildings.
- the insulating material according to the invention is suitable for these uses, in particular due to the combination of its features such as formability, resistance to flashing, fire protection, structure-borne noise reduction and thermal insulation.
