Definitions

  • the present invention relates to a spacer profile for a spacer frame, the edge area of an insulating washer unit to form a
  • the space between the panes is to be attached, with a profile body made of bad thermally conductive material and with a metal layer that with the to the plant the inside walls of the profile body have certain material cohesions connected is.
  • the washers of the insulating washer are normal within the scope of the invention Glass panes made of inorganic or organic glass, without the invention however, would be limited to this.
  • the panes can be coated or be refined in a different way to give the insulating washer unit special functions, such as increased thermal or acoustic insulation.
  • the profile body of the spacer profile made of poorly heat-conducting material comprises the volume of the main part of the spacer profile and gives it his cross-sectional profile.
  • cohesively connected is meant that the profile body and the metal layer are permanently connected to one another, for example by coextrusion of the profile body with the metal layer or by a separate lamination of the Metal layer, optionally via an adhesion promoter or similar techniques.
  • the thermal conductivities ⁇ for such Materials are typically on the order of 5 W / (m ⁇ K) and below, preferably they are smaller than 1 W / (m ⁇ K) and more preferably smaller than 0.3 W / (m ⁇ K). Plastics will generally fall under this definition.
  • plastics generally have a low level compared to metal Diffusion tightness.
  • spacer profiles made of plastic must therefore through special measures to ensure that existing in the area Air humidity does not penetrate the space between the panes to an extent that the absorption capacity of the spacer profiles usually Desiccant housed is soon exhausted and the insulating washer unit in their functionality is impaired.
  • a spacer profile must also be used also prevent fill gases from the space between the panes, such as Argon, krypton, xenon, sulfur hexafluoride, escape from this.
  • fill gases from the space between the panes such as Argon, krypton, xenon, sulfur hexafluoride
  • DE 33 02 659 A1 proposes which was used to form the preamble of claim 1, before, a spacer profile made of plastic with a vapor diffusion-tight layer (Vapor barrier) by clicking on the plastic profile on the side which faces away from the space between the panes when installed, a thin one Metal foil or a metallized plastic film applied or close to the surface is introduced.
  • This metal foil must be the space between the panes span as completely as possible so that the desired vapor barrier effect entry.
  • Such a spacer profile is then applied to the contact surfaces the system walls thinly applied sealant, vzw. of a butyl sealant based on polyisobutylene, with the inside of the pane by pressing connected.
  • the plastic profile body points to the space between the panes pointing ends of the investment walls clearly above the contact surfaces protruding contact ribs on the immediately when pressing get in contact with the discs. It turned out to be disadvantageous that the sealant layer through the contact ribs limiting the pressing is often not sufficiently connected to the surface of the pane, so that the Adhesion of the sealant to the inside of the pane is insufficient.
  • Another spacer profile is from the older priority DE 298 14 768 U1 known.
  • This highly insulating spacer profile includes one of the Plastic profile body formed desiccant chamber, on both sides Landing ridges are provided for planting on the inside of the pane, which Bridge sections are connected to the chamber.
  • the profile facing away from the space between the panes is one Provide metal layer, which also around the jetties up to their Can extend contact surfaces.
  • This embodiment has proven to be advantageous because of a metallic surface often better adhesion of the Profile to the commonly used sealant materials than with a Plastic surface can be achieved.
  • the following problems arise observed: If you stretch the metal layer over the entire system wall to to the end facing the space between the panes, so it can easily at Fiddling, e.g.
  • the technical problem underlying the invention then becomes the best solved when the depth of the indentation corresponds exactly to the thickness of the metal layer, so that the contact surface formed by the profile body and that of the metal layer formed contact surface lie exactly on one level, i.e. one step is completely avoided.
  • the depth the indentation for example, due to manufacturing tolerances of up to approximately 50% of the thickness of the metal layer deviates from the ideal depth, so that if necessary forms a very flat step in the contact surface.
  • the sealant typically has a thickness of about 0.2-0.4 mm is applied to the system walls while suitable metal layers typically have a thickness of only 0.1 mm or less, so that a Level in the contact surface of up to about half a metal layer thickness in If necessary, the scope of the invention is still tolerable.
  • Adequate adhesion of the system walls to the sealant as well as permanent Connection of the metal layer to the profile body in the area of the system walls is usually achieved when the metal layer is formed Investment area over about 20 to 80% of the total investment area of the respective System wall extends.
  • the diffusion density can usually be used Layers of spacer profiles made of plastic used metal foils or -sheets are used.
  • the metal layer can also be used directly of chemical or physical coating processes directly on the Profile body can be applied.
  • Metal layers applied with sufficient thickness are not only characterized by good diffusion tightness, but also have another advantage that they are plastically deformable, so that they are cold bendable profiles, such as those in DE 298 14 768 U1 or in DE 199 03 661.6 are described, are suitable.
  • Such metal layers work then arranged not only as a diffusion-tight layer, but at a suitable location also as reinforcing layers to facilitate bending.
  • preferred materials for the metal layer are stainless steel or with material containing chrome and / or tin on at least one surface coated iron sheet, the coating compared to the sheet thickness is made much thinner.
  • Iron sheets coated on the surface with tin are also known as tinplate.
  • Suitable types of stainless steel are e.g. 4301 or 4310 according to the German steel key.
  • the minimum layer thickness becomes too be choose that the required diffusion tightness as well as a desired mechanical behavior (e.g. bendability) can be achieved.
  • a minimum layer thickness of 0.02 mm is required for this.
  • thermoplastic Plastics with a thermal conductivity ⁇ ⁇ 0.3 W / (m ⁇ K), e.g. Polypropylene, Polyethylene terephthalate, polyamide or polycarbonate. Plastic may contain common fillers, additives, dyes, UV protection agents, etc.
  • FIG 1 is a first embodiment of a spacer profile according to the presented present invention.
  • the one made of black, for example Polypropylene existing profile body includes an inner wall 12, which in the built Condition facing the space between the panes, two to the system the inside of the pane certain wall 20 and 22 and a short Transition areas adjoining rear wall 18.
  • the approximately 1 mm thick walls 12, 18, 20, 22 defines a desiccant chamber 10 which later filled with hygroscopic materials. So that moisture from the Disc space can enter the desiccant chamber 10 are in the Inner wall 12 perforations 50 are provided.
  • the contact walls 20 and 22 are each with an indentation 60 in it to rest on the inside of the pane certain surface, which is at a certain distance from the Disc space-facing ends of the contact walls 20, 22 begins and extends over the entire remaining area.
  • a diffusion-tight metal layer 40 made of 0.125 mm thick chromed and with an adhesive layer Provided iron sheet arranged, which integrally connected to the profile body is.
  • the depth of the indentation 60 corresponds exactly to the thickness of the metal layer 40, so that the contact surface formed by the profile body 70 and that of the metal surface 40 formed contact surface 80 lie exactly in one plane.
  • the system for contacting the inside of the pane with the interposition of the sealant thus have certain contact surfaces 70, 80, apart from where appropriate existing manufacturing tolerances, a smooth surface and form a stepless level.
  • the desired are optimally Objectives achieved, a uniform pressing on the contact surfaces in the manufacture of the insulating washer unit with a thickness of about 0.25 mm Spacer profile provided with the sealant layer with the washers and counteract detachment of the metal layer 40 at its free end.
  • the contact surface 80 formed by the metal layer 40 has in this first example an area share of the total contact surface 70, 80 of the contact walls 20, 22 of about 65%.
  • the embodiment of the invention shown in Figure 2 is based on a profile body according to DE 298 14 768 U1. Through walls 12, 14, 16, 18 one Desiccant chamber 10 defines, the connection between this chamber 10 and the space between the panes via perforations 50 or the like is made.
