Definitions

  • the invention relates to a multi-pane insulating glass with a rim, e.g. as edge protection, according to the preamble of claim 1, in particular a fire protection glass with at least one toughened pane or a pane made of glass ceramic.
  • Multi-pane insulating glass consists of at least two glass panes, which are kept at a distance by a web inserted between the edges.
  • the web or spacer is usually formed by a generally metal profile, in which there is a desiccant, which is connected via openings to the space between the panes.
  • the web or spacer is offset somewhat inwards, so that a sealing compound can be introduced into the edge region between the panes, which causes the panes to hold together and at the same time seals the intermediate space from the atmosphere.
  • a seal usually made of butyl rubber / polyisobutene, is also used between the spacer and glass as a water vapor diffusion barrier (e.g. DE-PS 36 37 064).
  • edge protection are plastic profiles, through which the edge of the glazing is bordered, for example described in DE-PS 24 54 530, DE-PS 32 29 421 or DE-OS 36 19 780.
  • pressure compensation systems such as those described, for example, in DE-OS 36 37 064 are often used. These pressure compensation systems consist of a valve that opens in the event of a fire and thereby releases the increased gas pressure that builds up inside the insulating glazing due to the temperature increase before it causes the panes to burst.
  • profile strips can only be used as edge protection if they are provided with holes that correspond to the openings in the pressure compensation systems, which is complex in terms of production technology.
  • EP 202 555 A to use, as edge protection, a flexible band made of a gas-impermeable material which is provided with holes at the points for the pressure equalization openings.
  • the object of the invention is to find a multi-pane insulating glass with an inexpensive edge protection suitable as edge protection, with which, with the same size, panes of different thicknesses can also be bordered when using sealing compounds which absorb moisture from the air and below Dispensing of volatile reaction products can be crosslinked, can be applied immediately after the pane assembly, which does not cause long-term damage and can also be used without problems in glazing with pressure compensation systems.
  • the edge surround serving as edge protection for the multi-pane insulating glass according to the invention, in its raw state, consists of a flat, flexible band that is only through the application to the edge of the glass takes on its final shape.
  • the band also consists of a gas-permeable material.
  • These multi-pane insulating glasses are in particular fire-resistant insulating glasses with at least one toughened pane or a pane made of glass ceramic, in which silicone-based sealing compounds are used for reasons of fire protection.
  • the reaction products released during the crosslinking of the sealant in the case of the above-mentioned fire-resistant insulating glass in general acetic acid, can also be removed to the outside through the edge protection tape.
  • the tape can be attached to the disc in such a way that the glass edges and the edge of the disc are glued, e.g. the sealing compound itself, are coated, whereupon the tape is pressed; however, it is preferred if the tape (on one side) is provided with a self-adhesive layer. If the entire width of the tape is self-adhesive, make sure that either the adhesive is gas-permeable e.g. is porous or that the adhesive is only sporadic, e.g. is applied in a dot or strip pattern, so that there is sufficient uncoated tape surface between the adhesive islands, which allows gas to pass through.
  • the adhesive is gas-permeable e.g. is porous or that the adhesive is only sporadic, e.g. is applied in a dot or strip pattern, so that there is sufficient uncoated tape surface between the adhesive islands, which allows gas to pass through.
  • Another advantageous embodiment consists in that at the point opposite the sealing compound, i.e. usually in the middle of the tape to provide an adhesive-free zone.
  • This adhesive-free zone can be wider or narrower than the space between the panes filled with sealant. With a narrower zone, it only has to be ensured that the passage of gas is still possible to a sufficient extent.
  • Textile substrates in particular woven or felt tapes, but also tapes made of nonwoven are suitable as the material for the tape.
  • the textile substrates can consist of organic fibers or threads made of cotton, viscose, wool or plastic, for example polyester, etc., and particularly fire-resistant fibers, for example of post-chlorinated PVC, can also be used.
  • Textile substrates made of inorganic fibers, for example glass fibers, are also particularly suitable because they are inexpensive and non-combustible.
  • gas-permeable films or paper strips can also be used, which can also advantageously be equipped with self-adhesive.
  • the foils or the paper can additionally be provided with perforations, which enable an improved gas exchange.
  • the size of the perforations should be such that no or as little as possible uncured sealant can penetrate. Microperforations in which the openings are so small that water vapor but no water drops can pass through are particularly advantageous.
  • Paper as well as the film material can also be reinforced with reinforcing fibers, e.g. Glass or plastic fibers can be offset.
  • tapes made of open-pore foam rubber or foam plastic strips or tapes made of porous foils are also possible.
  • the foam strips and the foils must be free of plasticizers, since it has been shown that the plasticizers usually used have a long-term effect on the adhesion between the pane and the silicone sealant. In the case of sealing compounds which are insensitive to plasticizers, this requirement need not be observed; however, the tapes can then no longer be used universally.
  • the strips can also be metallized, which can sometimes offer optical and technical advantages.
  • the thickness of the strips should be such that the strips on the one hand provide adequate protection for the edge of the pane, but on the other hand they are still flexible enough to be easily placed around the edges or the edge of the pane.
  • thicknesses of 0.05 to 15 mm are possible for the tape.
  • the tape thicknesses are between 0.1 and 1.0 mm, when using textile tapes made from inorganic fibers about 0.1 to 0.8 mm;
  • Foils and paper are generally used with a thickness of 0.05 to 0.8 mm and foam foils should, depending on the mechanical hardness of the foam, be between about 0.2 and 15 mm thick.
  • the width of the strips should be so large that the strips or edges of the disks are secure, ie without risk of detachment of the tape from the edge of the disc. However, the width should not be so large that the tape looks out of the frame rebate after the pane has been installed in the window frame. In general, the tape should encompass the edge of the disk by about 15 mm each.
  • the band can also be arranged asymmetrically if this is considered desirable.
  • a band width can be used with different panes with different thicknesses, because if the pane thickness is varied by, for example, 5 mm, the overhang of the band on the pane surfaces changes by only 2.5 mm.
  • the double-pane insulating glass shown in FIG. 1 consists of the two glass panes 1 and 2, which are held at the desired distance from one another by a hollow profile 3 serving as a spacer.
  • a drying agent 4 in the form of granules.
  • the gas exchange between the drying agent 4 and the space 6 between the panes 1 and 2 takes place via perforations 5.
  • the hollow profile 3 is set back somewhat from the edge of the pane, around a joint for receiving the sealing compound 7, by means of which the panes 1 and 2 are glued together and sealed off from the outside.
  • sealing compound 7 a silicone sealing compound reacting with the air moisture and thereby crosslinking is preferably used, in which the reaction with the air humidity proceeds with the release of acetic acid.
  • the edge enclosure 9 serving as edge protection consists of a cotton fabric tape which is provided with a gas-permeable adhesive layer and is glued around the edges of the panes 1 and 2 and via the sealing compound 7.
  • the adhesive layer is not shown separately. All conceivable adhesives are suitable as an adhesive for the edge enclosure 9, as long as they enable a sufficiently firm connection of the edge enclosure 9 with the glass panes and, upon contact with the sealing compound 7, do not cause any harmful reactions which impair the pane assembly.
  • the edge surround 9 is drawn around the edges to different degrees and extends further over the edge of the pane on the right side than on the left side.
  • FIGS. 2 and 3 show sections of tapes which are suitable as peripheral edging before being attached to the pane, to be precise seen on the adhesive side.
  • the tape according to Figure 2 consists of a fabric tape; the self-adhesive coating is applied in strips 10 which run obliquely to the direction of tape travel. The areas of the tape which are free of adhesive and lie between the adhesive strips 10 allow sufficient gas passage so that the crosslinking of the sealant and the removal of the reaction products formed during the crosslinking is ensured.
  • FIG. 3 shows a tape which consists of a gas-permeable film and is completely provided on one side with a self-adhesive coating. The gas exchange between the sealant and the atmosphere is improved here via the perforations 11 which are arranged in the center of the band and which run in the region of the sealant when the band is attached to the disk.
  • the adhesive layer is not shown separately here.
  • edge surround suitable as edge protection is inexpensive to manufacture, that the band used as the edge surround can be stored in roll form before being applied to the edges, that a bandwidth can be used for glazing of different thicknesses, which the Warehousing is simplified and, above all, that the edge surround can be used immediately after the production of the composite pane even with sealing materials that require gas exchange with the atmosphere for a long time to crosslink, as well as for glazing with pressure compensation systems.
