Definitions

  • the invention relates to a spacer for insulating glazings with profiled side walls and a glazing and their use.
  • the thermal conductivity of glass is about two to three times lower than that of concrete or similar building materials.
  • slices are in most cases much thinner than comparable elements made of stone or concrete, buildings often lose the largest proportion of heat through the exterior glazing. This effect is particularly evident in skyscrapers with partial or complete glass facades.
  • the additional costs for heating and air conditioning systems make a not inconsiderable part of the maintenance costs of a building.
  • lower carbon dioxide emissions are required as part of stricter construction regulations.
  • An important solution for this is insulating glazing. Insulating glazings are indispensable in building construction, especially in the context of ever faster rising raw material prices and stricter environmental protection regulations. Insulating glazings therefore make up an increasing part of the outward glazing. Insulating glazing usually contains at least two glass or polymeric materials.
  • the disks are separated from each other by a gas or vacuum space defined by the spacer.
  • the thermal insulation capacity of insulating glass is significantly higher than single glass and can be further increased and improved in triple glazing or with special coatings.
  • Silver-containing coatings for example, allow a reduced transmission of infrared radiation and thus reduce the heating of a building in summer.
  • optical and aesthetic features also increasingly play an important role in the field of building glazing.
  • the insulation not only plays an important role for cost reasons. Because the Thermal insulation of the usually very thin glass compared to the masonry is worse, improvements in this area are necessary. In addition to the nature and structure of the glass, the other components of a double glazing are of great importance. The seal and above all the spacers have a great influence on the quality of the insulating glazing.
  • a barrier film on the spacer.
  • This foil is usually attached to the spacer in the area of the outer seal.
  • Common film materials include aluminum or stainless steel, which have good gas tightness. The metal surface ensures at the same time a good bonding of the spacer with the sealant.
  • DE 40 24 697 A1 discloses a waterproof multi-pane insulating glass comprising at least two glass sheets and a profile spacer.
  • the seal is made over polyvinylidene chloride films or coatings on the spacer.
  • the edge bonding can be done using a polyvinylidene chloride-containing solution.
  • EP 0 852 280 A1 discloses a spacer for multi-pane insulating glazings.
  • the spacer comprises a metal foil on the bonding surface and a glass fiber content in the plastic of the base body.
  • DE 196 25 845 A1 discloses an insulating glass unit having a thermoplastic olefin spacer.
  • the spacer has a water vapor permeability of less than 1 (g mm) / (mm 2 d) and a high tensile strength and Shore hardness. Furthermore, the spacer comprises a gas-tight film as a water vapor barrier.
  • EP 0 261 923 A2 discloses a multi-pane insulating glazing with a moisture-permeable foam spacer with an integrated desiccant.
  • the arrangement is preferably sealed by an outer seal and a gas and moisture-proof film.
  • the film may contain metal-coated PET and polyvinylidene chloride copolymers.
  • WO 2013/104507 A1 is a spacer for multi-pane glazing at least comprising a composite known from a glass fiber reinforced polymer body with two parallel side surfaces or disc contact surfaces, a bonding surface and a glazing cavity surface, wherein the wafer contact surfaces and the bonding surface are connected directly or via connecting surfaces, and with an insulating film on the bonding surface and the bonding surfaces, wherein the insulating film at least one polymeric film in a thickness of 10 .mu.m to 100 .mu.m, at least one polymeric layer in a thickness of 5 .mu.m to 80 .mu.m and a metallic layer having a thickness of 10 nm to 1500 nm or a ceramic layer having a thickness of 10 nm to 1500 nm.
  • the disc contact surfaces are flat.
  • One of the most important features of the insulating glass pane is the tightness of the trapped gas volume against external moisture.
  • the tightness is ensured by a combination of a spacer with a sealant such as a butyl sealant or butyl rubber and the respective adjacent glass surface.
  • An important parameter is the width of the butyl seal on both the glass surface, as well as on the side surfaces of the spacer.
  • the width of the Butylabdichtung on the glass surface is not changeable by the smooth surface of the glass.
  • the total length of Kotakt Structure to the spacer profile corresponds to a planar version of the width on the glass side and thus corresponds to the order width of Butylschnur in the sealing process.
  • the object of the invention is to provide a spacer for an insulating glazing, which has the usual advantages and an improved, long-term stable insulation with simultaneous easy installation and improved tightness between the spacer and the glass surfaces.
  • the spacer according to the invention for multiple-pane insulating glazing comprises at least one polymeric base body with two parallel disc contact surfaces and a hollow chamber, wherein the disc contact surfaces have a wave-shaped form.
  • the spacer comprises at least one composite of a glass-fiber-reinforced polymer base body and a polymeric insulation film.
  • the main body preferably has a glass fiber content of 20 wt .-% to 50 wt .-%, more preferably from 30% to 40% by weight. The glass fiber content in the base body simultaneously improves the strength and stability.
  • the insulation film comprises at least one polymeric film. At least one further polymeric layer in a thickness of 10 .mu.m to 100 .mu.m and a metallic or ceramic layer with a thickness of 10 nm to 1500 nm are applied to the polymeric film.
  • a preferred embodiment of the invention is a spacer, wherein the disc contact surfaces have a wavy shape along the longitudinal side.
  • the longitudinal waveform has proven to be particularly advantageous.
  • a waveform having a right angle to the long side such as a diagonal waveform or combinations of all waveforms is advantageous because each waveform increases the surface area of the side cheeks.
  • a preferred embodiment of the invention is a spacer, wherein the undulating shape has on the disc contact surface longitudinally 2 to 10 elevations. With this number of waves good results are achieved.
  • a preferred embodiment of the invention is a spacer, wherein the undulating shape has on the disc contact surface longitudinally 3 to 6 elevations. With this number of waves particularly good results are achieved.
  • a preferred embodiment of the invention is a spacer, wherein the ridges of the waves are from 0.1 mm to 1 mm.
  • the wall thickness of the spacer is about 1 mm.
  • the increase is preferably about 0.5 mm depending on the number on the disc contact surface.
  • the waveform can be coarse but also fine.
  • the waveform can also be partially or completely replaced by a rauting, that is, by horizontal and vertical lines divided into regular rectangles.
  • the shape of the side cheeks is also possible with sharp-edged flanks as a special form or as an extreme shape of the shaft.
  • a significant improvement of the contact surface to the sealant is achieved by the profiling of the side cheeks according to the invention.
  • the increase in contact area is about 30%, which improves the seal Spacer on the glass side also corresponds to about 30%.
  • the application of the butyl seal is improved because the contact area on the side cheeks to the seal is greater.
  • a preferred embodiment of the invention is a spacer, wherein on the outer surface of the polymeric base body, an insulating film is applied, which contains at least one polymeric layer and a metallic layer and / or a ceramic layer.
  • the polymeric layer has a thickness of 5 microns to 80 microns. In another preferred embodiment, the thickness of the polymeric layer is 10 ⁇ m to 80 ⁇ m.

  • connection of the individual components can take place via an adhesive.
  • the use of an insulating film with alternating layer sequence is particularly advantageous in terms of the tightness of the system. An error in one of the layers does not lead to a loss of function of the insulation film. By comparison, even a small defect in a single layer can lead to complete failure. Furthermore, the application of several thin layers compared to a thick layer is advantageous, since the risk of internal adhesion problems increases with increasing layer thickness. Furthermore, thicker layers have a higher conductivity, so that such a film is thermodynamically less suitable.
