Definitions

  • the invention relates to spacers for insulating glazing made of polymeric material and glass in the form of profiles, which often also contain a desiccant.
  • the products according to the invention aim, together with sealants or adhesives, to seal the gas-filled interspaces in insulating glazings in a gas-tight and water-tight manner.
  • Heat-insulating glazing has become increasingly important, especially against the background of resource-saving energy use, and has been the subject of numerous improvements and inventions in the past.
  • a large number of embodiments for insulating glazing and its components are therefore known.
  • insulating glazing consists of two or more translucent panels with air and water (steam) gas-tight interspaces that are spaced apart by webs or profiles, so that the glazing has a heat-insulating and possibly also sound-absorbing effect.
  • Tables made of glass or transparent plastic are usually used as translucent boards.
  • the use of plastic films between the outer panels of insulating glazing is also known. To improve the properties (e.g. improved sun protection), the panels used can additionally be surface-treated or coated.
  • the spaces between the panels of double glazing are usually with dehumidified air or gases or gas mixtures that conduct heat less than air, such as, for. B. argon, sulfur hexafluoride or argon / krypton mixtures filled.
  • the gas fillings are dehumidified to prevent the panels from fogging up inside the glazing at low temperatures.
  • insulating glazing In order to prevent an exchange of the gas fillings with (moist) ambient air and / or the penetration of water (moisture) into the insulating glazing, insulating glazing must be sealed around its circumference.
  • various sealing concepts and sealing compounds are known from the prior art. Components of the sealing concepts are - with a few exceptions apart from that - also the spacers, which are used in the insulating glazing to keep the panels at defined distances from each other.
  • the spacers are produced in the form of a frame in accordance with the shape of the insulating glazing panels from hollow profile bars, the profile cross section usually being more or less rectangular.
  • such a frame-shaped spacer with a rectangular cross-section is first provided with a sealing and adhesive compound on the side surfaces that will later face the glass panels and then glued to the periphery of the glass panels, so that firstly a firm bond is formed and secondly, the space between the insulating glazing is largely sealed.
  • the outer surface of the spacer frame usually forms a U-shaped joint together with the slightly protruding panels, which is additionally sealed with a sealing compound from e.g. B. polyurethane or polysulfide can be filled.
  • a sealing compound from e.g. B. polyurethane or polysulfide can be filled.
  • an adhesive between the spacer frame and board usually serve z. B. masses containing butyl.
  • Standard spacers today are mainly made of aluminum alloys. Rectangular hollow profiles filled with hygroscopic desiccants have largely prevailed, which are slotted on the side facing the space or have small openings, so that moisture which has penetrated into the space between the insulating glazing can be absorbed by the desiccant. As a result, the residual moisture in the insulating glazing remains sufficiently low to prevent fogging.
  • Molecular sieves or silica gel are preferably used as drying agents.
  • Spacers made of metals are very suitable for insulating glazing on the one hand because of their high mechanical strength values and their gas impermeability, but on the other hand they also pose numerous problems.
  • Aluminum in particular has a comparatively high thermal conductivity.
  • the spacer thus forms a thermal bridge, which worsens the thermal insulation effect of the double glazing. Due to the high thermal conductivity of the spacer, it can be used under extreme weather conditions In the case of commercially available double glazing with aluminum spacer frames, observe fogging or even icing of the glazing in the edge area. Due to the compared with z. B. Glass with very different coefficients of thermal expansion, metal spacers can also lead to severe stress conditions in the glazing, which may even result in glass breakage or damage to the sealing of the space. In addition, metal spacers deteriorate the recycling behavior of insulating glazing, since all metallic components of the glazing must be separated before the glass recycling process.
  • Plastic spacers made of plastic have therefore already been produced, in particular because of their low thermal conductivity compared to metals. Polymer spacers can be easily incorporated into glass recycling processes. However, plastics generally have a certain gas and water vapor permeability. Plastic spacers therefore do not prevent the interstice filling of insulating glazing from being replaced with the surrounding atmosphere in the long term, which can ultimately result in a considerable deterioration in the thermal insulation effect. However, various attempts to solve this problem are also known.
  • WO 91/02133 describes, for example, multiple glazing that contains at least one spacer (as a full profile) made of closed-pore, foamed plastic, along with any other conventional hollow (preferably metallic) spacers, and that can also be sealed with a gas-impermeable adhesive tape on the circumference of the insulating glazing .
  • Multi-layer plastic packing tapes are preferably used, which also z. B. can be coated with metal.
  • WO 92/08030 describes, inter alia, a spacer / sealing system in which the spacer made of heat-insulating organic material, such as. B. cardboard is produced and is coated on selected surfaces (parts) with a gas-impermeable layer of plastic and / or metal.
  • WO 91/00409 discloses a gas-impermeable spacer which is produced from a hardenable plastic resin in the form of a hollow profile and which is reinforced with fiber material. At least in the side wall of the spacer facing outward in the case of insulating glazing, a layer of a moisture-impermeable material is embedded, which is also at least partially covered on both sides with fiber material and is intended to protect the interspace from the ingress of moisture.
  • the gas permeability of the spacers is in part noticeably reduced, but exposed metal foils or metal coatings in particular are mechanically very sensitive to damage, which then nullifies the blocking effect.
  • the proposed embedding of the layers together with reinforcing fiber material means increased production costs.
  • the use of metal-containing spacers also significantly reduces the recycling behavior of the insulating glazing.
  • the spacer for insulating glazing according to claim 1 which comprises at least one base body made of (possibly reinforced) polymeric material and at least one layer of glass which, in the case of insulating glazing formed with the aid of the spacer according to the invention, has the gap defined by the spacer covered as completely as possible between adjacent panels.
  • the layer is therefore preferably arranged perpendicular to the glazing panels.
  • the material glass is impermeable to gas and water vapor and thus has the necessary barrier effect to prevent the interstice filling with air or the penetration of moisture over long periods in insulating glazing. Since the spacer according to the invention, apart from any non-metallic reinforcements, consists only of polymeric material and glass and is therefore poorly heat-conducting, the problem of the formation of thermal bridges in insulating glazing produced with spacers according to the invention in the edge region of the glazing is also eliminated. The recycling behavior is also not affected because the spacer according to the invention contains no metal parts.
  • the spacer according to the invention can be produced according to the prior art in a variety of shapes and dimensions, so that it can be used as an alternative to conventional spacers in almost all known designs of insulating glazing that use or can use profile rod spacers.
  • the spacer according to the invention is designed as a hollow profile which, like conventional spacers made of e.g. B. aluminum can be processed. So z. B. from a preferably rectangular spacer hollow profile according to the invention, a frame can be created in a manner known per se, which is glued to the size of the panels with two glass panels of suitable size, whereby a firm bond is created.
  • insulating glazing is obtained from two glass panels held at a defined distance, the space between being largely sealed in a gastight and moisture-tight manner.
  • the intermediate space can be filled with dehumidified air or dry gases or gas mixtures which conduct heat less than air.
  • the layer of glass used to reduce the gas and water vapor permeability of the spacer according to the invention (cf. FIG. 1) is applied to a side surface of the rectangular hollow profile in the preferred embodiment of the spacer according to the invention considered here and is arranged such that it is in the finished insulating glazing located on the outside of the frame and covers the gap between the connected glass panels as much as possible. A gas exchange between the surroundings and the space filling of the double glazing is almost impossible.
  • the glass panels and the glass layer of the spacer are themselves impermeable to gas, and the diffusion resistance of the adhesive seams between the glass panels and spacer frame is so high when using the sealing or adhesive compositions known from the prior art and because of the geometric conditions that gas exchange is largely excluded .
  • Insulating glazing with spacers according to the invention can easily achieve lifespans of over 10 years without sacrificing quality in terms of thermal insulation and condensation.
  • the diffusion-inhibiting glass layer of the spacer frame according to the invention is interrupted only as little as possible. This is e.g. B. achieved by the glass layers of the two corner spacer frame parts are joined together precisely and glued.
  • constructions with overlapping glass layers are also possible, which can be realized by rounding off using the smallest bending radius of the glass layer.
  • the glass layer of the spacer according to the invention used as a diffusion barrier is preferably 10 to 100 ⁇ m thick and therefore has a certain flexibility, which also allows a flexible shaping of the spacer according to the invention.
  • a 50 ⁇ m thick layer of borosilicate glass has a minimum bending radius of 10 mm.
  • the glass layer is preferably already connected to the polymeric material during the production of the base body, which is preferably carried out by means of extrusion.
  • the glass layer can e.g. B. applied to the base body or directly into the base body without additional reinforcement by z. B. fiber material can be embedded.
  • One or more outer or inner surfaces of the base body, which can also be curved, can be provided with a glass layer.
  • FIGS. 1 to 5 Different embodiments of the spacer according to the invention are shown in FIGS. 1 to 5, 1 each identifying the polymeric base body and 2 each a glass layer.
  • the cross section of the spacer profile is shown in each case.
  • the invention is not limited to the embodiments shown here.
  • Knowledge of the state of the art opens up a wide variety of other design and production variants to the person skilled in the art.
  • the glass layer or the glass layers can be connected to the polymeric base body in any mechanical-physical or chemical manner. So z. B. of course one or more layers of glass subsequently by z. B. Adhesive can be applied to the polymeric profile, which may already contain embedded glass layers.
  • the spacer according to the invention is preferably designed as a hollow profile like conventional spacers and is filled with a desiccant. Particularly suitable as drying agents are granular, free-flowing substances, such as, for. B. Molecular sieves.
  • the spacer according to the invention preferably has, in a manner similar to that known from the prior art, one or more slits or openings in the side wall which later faces the enclosed space in the insulating glazing, so as to keep the residual moisture in the space filling low and to prevent fogging. All possibilities known from the prior art are considered as interstice filling, since the glass layer used according to the invention as a diffusion barrier is effective with all gases or gas mixtures conventionally used as filling.
  • the basic body made of polymeric material can in principle be embedded in the polymeric material by non-metallic reinforcements - e.g. B. fiber material such as glass fibers, natural fibers or glass wool - be reinforced to improve the mechanical properties.
  • B. fiber material such as glass fibers, natural fibers or glass wool - be reinforced to improve the mechanical properties.
  • the base body consists only of polymeric material.
  • the production z. B. a glass fiber reinforced hollow profile made of polymeric material by means of extrusion is well known to those skilled in the art. However, preference is given to using polymeric materials which, in the solidified state without reinforcement, already have sufficient strength properties.
  • the coefficient of thermal expansion should also correspond as closely as possible to that of the glazing panels provided. There are also such polymers Preferred materials that contain as few volatile components as possible.
  • the polymeric material used should also be largely UV-resistant.
  • the spacer according to the invention can be provided with UV-resistant coatings, coatings, varnishes or the like as a substitute or in addition to at least the surfaces later exposed to the sun.
  • Such coatings or coatings can moreover also be applied to the spacer according to the invention in order to change other properties such as adhesive properties, appearance, etc.
  • These include e.g. B. also plasma surface modifications z. B. with SO 2 .
  • Suitable polymeric materials are e.g. B.
  • polyester preferably polybutylene terephthalate or polyethylene terephthalate, polyamides, polyimides or polyvinyl acetate.
  • the polymeric material can even be partially or completely foamed.
  • basic bodies made of different polymeric materials can also be made from several parts to form a solid composite, the individual parts being partly foamed, partly unfoamed, cf. Figure 6.
  • the unfoamed part of the base body is identified here with 1a, the foamed part with 1b.
  • the spacer according to the invention can be combined with almost all conventional glazing panels and adhesive and sealing compounds to form insulating glazing.
  • a composite with glass panels is preferred, since the advantages in the recycling behavior of the insulating glazing are particularly evident here.
