Definitions
- the invention relates to a spacer profile for a spacer frame which in Edge area of an insulating pane unit to form a space between the panes is to be attached with a profile body made of poorly heat-conducting material and with a Diffusion-tight metal foil that is firmly bonded to the profile body.
- the washers of the insulating washer unit are normal within the scope of the invention Glass panes made of inorganic or organic glass, but without the invention would be limited to this.
- the panes can be coated or refined in some other way be to the insulating pane unit special functions, such as increased thermal insulation or Soundproofing.
- the profile body of the spacer profile comprises poorly heat-conducting material by volume the main part of the spacer profile and gives it its cross-sectional profile.
- profile body and the metal layer are permanent are interconnected, for example by coextruding the profile body with the Metal layer or by a separate lamination of the metal layer, optionally over an adhesion promoter or similar techniques.
- the thermal conductivity values ⁇ for such materials are typically in the Of the order of 5 W / (m * K) and below, preferably they are smaller than 1 W / (m * K) and more preferably less than 0.3 W / (m * K). Plastics are usually among these Fall definition.
- plastics generally have a lower level than metal Diffusion tightness. With spacer profiles made of plastic must therefore by special Measures are taken to ensure that the ambient humidity in the area is not penetrates the space between the panes to such an extent that the absorption capacity of the Spacer profiles usually placed desiccant is soon exhausted and the Insulating pane unit is impaired in its functionality. Next must Spacer profile also prevent filling gases from the space between the panes, such as for example argon, krypton, xenon, sulfur hexafluoride, escape from this. Conversely, nitrogen, oxygen, etc. contained in the ambient air should not be in the Enter the space between the panes. As far as the following is concerned about diffusion tightness, this means both vapor diffusion tightness and gas diffusion tightness for the called gases.
- EP 0 430 889 A2 proposes a spacer profile To provide plastic with a vapor diffusion-tight coating by immediately on the plastic profile on the side that, when installed, from the space between the panes a thin layer, for example made of chrome or a chrome-nickel alloy, is applied by means of a physical coating process, for example by sputtering. These manufacturing processes are complex and only allow manufacturing extremely thin vapor diffusion-tight layers at a reasonable cost.
- spacer profiles are preferably used as one-piece spacer frames manufactured, which are bent at three corners and where the connection of the end pieces over a corner connector inserted into the end pieces or a straight connector. in this connection one strives to carry out corner bending as simply as possible in terms of production technology, in particular without extensive prior heating.
- the profiles of EP 0 430 889 A2 are not suitable for spacer frames.
- the ones there in thicknesses of 70 - 400 nm applied vapor diffusion-tight layers do not have the required Tensile strength.
- spacer profiles have been developed in which the profile body is made of poorly heat-conductive, elastic-plastically deformable material with a plastically deformable reinforcing layer, preferably a metal foil, is integrally connected.
- This reinforcement layer can also be made diffusion-proof and the entire width of the Spanning the space between the panes, which ensures the required diffusion tightness of the Spacer profile is reached.
- Such a spacer profile was called THERMOPLUS® TIS® for example in the brochure "Impulses for the future" of flat glass AG presented and is described in DE 298 14 768 U1.
- the reinforcement layer gives the spacer profile has good cold bendability for producing the above-mentioned one-piece spacer frame.
- the object of the invention is the object of the invention, with a spacer profile made of poorly heat-conducting Material with diffusion-proof metal foil in a cost-effective way for an improved To provide corrosion protection.
- the invention is also intended to provide aesthetically enable attractive spacer profiles and especially for cold-bendable Spacer profiles, e.g. according to DE 298 14 768 U1.
- the invention provides that the diffusion-tight metal foil at least on the surface facing away from the professional body with a Corrosion protection coating is provided, which is a layer of chrome or a Chromium alloy comprises, whose thickness compared to the thickness of the metal foil by at least a factor of 2.5, preferably by at least a factor of 10 and more preferably by at least Factor 20, is lower.
- a Corrosion protection coating is provided, which is a layer of chrome or a Chromium alloy comprises, whose thickness compared to the thickness of the metal foil by at least a factor of 2.5, preferably by at least a factor of 10 and more preferably by at least Factor 20, is lower.
- the thickness of the layer of chromium or a chromium alloy is less than about a tenth of the thickness of the metal foil.
- the layer preferably has a thickness between 0.01 ⁇ m and 5 ⁇ m. This makes it extremely thin compared to the metal foil achieved that the heat conduction through the spacer profile by the application of Corrosion protection coating is not significantly increased, the additional costs low remain and the (cold) bendability of the spacer profile is not impaired.
- there a pure chrome layer is preferably used.
- the metal foil preferably has a layer of chromium or one on both surfaces Chrome alloy on. With the additional layer on the side facing the profile body Surface can improve the adhesion of the film to the plastic of the profile body become.
- the chromium-containing layer is usually at least superficially oxidized. It is known that chromium can be easily oxidized, so that a freshly produced product comes into contact with it Chromium surface with oxygen quickly forms a thin passivating oxide layer, which then further progress of the oxidation is effectively prevented or greatly slowed down.
- a further improvement in the adhesion of the metal foil to the profile body can be achieved if the chromium-containing layer has an adhesive layer on the side facing the profile body, in particular with an adhesive varnish.
- Adhesive varnishes in particular which are suitable for the production of automotive decorative profiles from metal-plastic laminates are common and the typically applied in a thickness of about 5 - 10 microns, as well suited proved.
- the metal foil in the installed state of the Spacer profile can be seen in areas from the outside, in particular then, when the metal foil on the contact webs facing the inside of the pane of the spacer profile extends very far towards the space between the panes.
- the shiny metallic surface of the metal foil stands out from the matt surface of the mostly dark colored plastic profile body from conspicuously, so that tolerance-related Fluctuations in the position of the side ends of the metal foil are particularly visible. That is aesthetically unsatisfactory. It can also be detrimental and too potent Corrosion susceptibility if the metal foil - with or without a chromium-containing layer - the Is exposed to sunlight or other light sources.
- the metal foil at least on the surface facing away from the profile body with a Corrosion protection coating comprises a colored lacquer coating, wherein whose thickness compared to the thickness of the metal foil by at least a factor of 2.5, preferably by at least a factor of 10.
- the varnish coating is advantageous applied in a thickness of 1 to 30 ⁇ m, usually with a thickness of 3 to 10 ⁇ m. It has It has been shown that with such thick coatings applied to the metal foil Achieved high corrosion resistance of the metal foil even under extreme conditions can be. The small thickness compared to the metal foil ensures that the additional costs remain low and the (cold) bendability of the spacer profile does not is affected.
- Paint coating means in connection with the invention a thin, by spraying, Immersion or similar coating application applied coating from a liquid and / or powder-solid substance, which by chemical reaction and / or physical Change an abrasion-resistant, adhering to the metal foil even when bending coherent film forms and at the same time a decorative and corrosion-resistant Function.
