Definitions

  • the invention is in the field of heatable multi-pane insulating glass consisting of at least two glass panes which are kept at a distance by a spacer and have a gas-filled or evacuated intermediate space.
  • a multi-pane insulating glass of this type on the interspace-side surface of one of the two glass panes there are wafer-thinly applied electrical conductor tracks designed as resistance heating elements with corresponding connections for the passage of an electrical current.
  • the glass pane is heated when an electrical current is applied to the conductor tracks, absorbs heat and is said to emit the heat into the air of a room in a building by convection and / or radiation.
  • the spacer must ensure special properties in the construction of the multi-pane insulating glass.
  • the plastic in the intermediate space forms an insulating web, which consists of a mixture of a fully formulated, phase-unstable, low-viscosity polyol formulation that contains a water-binding additive (Baydur VP PU 1397) with a liquid, solvent-free diphenylmethane-4,4'-diisocyanate with a Content of isomers and higher functional homologues (Desmodur 44 V10 B or Desmodur 44 V20 B) is produced (Baydur: manufacturer Bayer AG; Desmodur: manufacturer Bayer AG).
  • the insulating web is e.g.
  • the hollow profiles of the spacer are filled with a desiccant.
  • a water vapor-impermeable putty in particular made of butyl, is arranged between the outer walls of the spacer and the intermediate surfaces of the glass panes.
  • the space below the spacer is filled with a more or less plastically elastic putty, especially with Thiocol.
  • the success described in the applicant's older proposal is based essentially on the choice of material for the insulating material between the spacer tubes.
  • the selected insulating material is in some cases not gas-impermeable, in particular water vapor-impermeable, so that moisture penetrates into the interior of the insulating glass and impairs both the thermal insulation of the insulating glass and the electrical insulation of the insulating material.
  • no success has yet been recorded.
  • the object of the invention is to improve the spacer known from DE-GM 88 12 216.6 for a heatable multi-pane insulating glass so that it ensures long-term gas tightness, but in particular water vapor tightness in the installed state and maintains its excellent electrical insulating ability.
  • the heatable multi-pane insulating glass is placed in a frame of a window or a door (not shown). It essentially consists of the two glass panes 1 and 2 arranged parallel to one another and at a distance from one another, between which an intermediate space 3 is provided. Conductor tracks 5 of a resistance heating element (not shown) are e.g. evaporated. The electrical connections and the overall structure of the resistance heating element need not be described, because they belong to the prior art and are not critical for the purposes of the invention.
  • the space 3 is bridged by a spacer 6, which is shown frontally in FIG. 2 and whose construction is essential to the invention.
  • the spacer 6 preferably consists of two aluminum hollow profiles 7 and 8 arranged parallel to one another and at a distance from one another, with side walls 7a, 7b and 8a, 8b parallel to the glass pane surfaces, a bottom wall 7c, 8c and a top wall 7d, 8d.
  • Through holes 9 are made in the ceiling wall, which, as is known, create a connection between the interior 10 of the hollow profiles 7, 8 filled with drying agent 11 and the intermediate space 3.
  • a butyl layer 12 is expediently arranged as a connecting element and as a water vapor barrier.
  • other connecting substances can also be provided there that serve the same purpose.
  • the space 13 under the spacer 6 is expediently filled with a putty 14, for example with Thiokol.
  • the putty serves as a plastic-elastic connection and adhesive.
  • the intermediate space 15 between the two hollow profiles 7, 8 is filled with a product which results in a hard material which firmly bonds with aluminum or adheres firmly to the aluminum and creates a uniformly rigid, torsion-resistant spacer, and above all Excellent electrical insulation and also an extremely low one
  • the product or substance must be UV and heat resistant. A substance has been found for this purpose through an inventive selection.
  • insulating web 16 which consists of a non-foamed, hardened polyurethane casting compound.
  • the raw material for this insulating material web 16 is traded under the trade name "Baydur VP PU 1397" from Bayer AG. It is a fully formulated, phase-unstable, low-viscosity polyol formulation that contains a water-binding additive. The mixture must be homogenized well before processing. Stir slowly during processing.
  • the formulation has the following properties: Hydroxyl number (mg KOH / g) 355 ⁇ 20 Water content (%) ⁇ 0.20 Viscosity ** at 25 ° C (mPa s) 1200 ⁇ 200 PH value about 11.5 Density at 25 ° C (g / cm3) about 1.05 Flash point *** (° C) 120 ° C Solidification area (° C) - 28 to - 26 ° C The lower limit of the processing temperature is 23 ° C.
  • the activity of Baydur VPPU 1397 can be changed at temperatures above 35 ° C.
  • the processing temperature of the raw materials should be at least 23 ° C.
  • the following processing recipes result: 100 parts by weight of Baydur VP PU 1397 97 parts by weight of Desmodur 44 V 10 B or 97 parts by weight of Desmodur 44 V 20 B
  • the following processing characteristics are determined at a raw material temperature of 28 ° C and are characteristic of the system: Gel time (s) 30 ⁇ 10 Tool temperature (° C) 30-75 Molded bulk density (kg / m3) 1180
  • 1000 kg Baydur VP PU 1397 with 970 kg Desmodur 44 V 10 B are weighed in at a processing temperature of the raw materials of 23 ° C and stirred with a stirrer at about 2000 rpm for 10 seconds.
  • the setting time between the start of stirring and the setting of the reaction mixture is 60 + 10 seconds. At the time of setting, the casting compound solidifies suddenly.
  • Baydur VP PU 1397 is a preparation based on polyols.
  • the insulating web 16 has, for example, the following properties: Baydur VP PU 1397 / Desmodur 44 V 10 B Specimen density mm 1010 Bulk density DIN 53432 kg / m3 1170 Flexural strength DIN 53432 MPa 72 Deflection b. fracture DIN 53432 mm 20th Bending modulus of elasticity MPa 1500 tensile strenght DIN 53432 * MPa 47 Elongation at break DIN 53432 % 21st Impact strength DIN 53432 kJ / m2 60 Shore-D hardness DIN 53505 74 Behavior in heat b. Bending stress DIN 53432 ** ° C 110 The processing shrinkage is only 0.8 ⁇ 0.1% manufacturing tolerance.
  • This value applies to the manufacture of an up to 100 mm thick insulating material web 16 with a bulk density of 1180 kg / m3 if the specified processing recipe with Desmodur 44 V 10 B and a mold retention time of 1 minute are maintained in a mold tempered to 75 ° C.
  • Desmodur 44 V 10 B is a liquid, solvent-free diphenylmethane-4,4'-diisocyanate with a certain content of isomers and higher functional homologues. It is used in conjunction with polyols to manufacture Baydur. It usually has the following delivery specification: Isocyanate content 31.5% by weight ⁇ 1% by weight Viscosity at 25 ° C 130 mPa.s ⁇ 20 mPa.s Acidity Max. 0.06% by weight Total chlorine Max. 0.5% by weight Phenyl isocyanate content Max.
  • the technical characteristics are: colour brown Density at 20 ° C 1.23-1.24 g / cm3 Flash point over 200 ° C Vapor pressure (MDI) at room temperature ⁇ 10 ⁇ 5 mbar
  • MDI Vapor pressure
  • the selected material for the insulating web 16 fulfills all the required properties.
  • the selected plastic which is to provide thermal and electrical separation, in order to achieve optimum separation properties in the corner area as well .
  • the new spacer profile in the corner area can be bent to the corner without the plastic hindering the bending.
  • Another favorable property of the selected polyurethane plastic is that it can be permanently combined with the lacquers already developed for aluminum spacers, so that colored spacers can also be created.
  • the use of UV-resistant paints is possible.
  • Another particularly important possibility is to color the polyurethane plastic and in this way to create a decorative spacer.
  • the electrical insulation of the insulating material web 16 is also perfect.
  • the insulating material web 16 made of the special material is permeable to water vapor if the water vapor partial pressure exceeds a certain size.
  • the water vapor can reach the insulating web 16 from the outside through the room 13 or through the cement 14 in the room 13. If water vapor penetrates the insulating material web 16, the electrical insulating capacity is reduced or electrical conductivity can occur. If the water vapor penetrates the insulating material web 16, it reaches the space between the panes 3 and is adsorbed by the desiccant 11 located in the spacer hollow profiles 7, 8 until the desiccant is used up.
  • the invention solves the problem in an incredibly simple manner by providing a spacer 6 in which the outer surface 16a facing the space 13 is covered with a layer 17 impermeable to water vapor.
  • This layer 17 consists e.g. made of butyl, a material that is also used on the side of the spacer 6 as a water vapor impermeable and sticky layer 12.
  • the spacer 6 can be handled - spacers are supplied cut to length in the form of bars to insulating glass manufacturers - the free surface 17a of the sticky butyl layer 17 is covered with a paper and / or plastic tape 18, so that the stickiness of the butyl does not interfere with handling and the free surface of the butyl layer 17 is not dirty.
  • the tape 18 is removed shortly before the spacer 6 is installed between the glass panes 1, 2 and the butyl layer 17 is contacted with the putty 14.
