Definitions
- the invention relates to an insulating glass unit with a Inner pane, an outer pane and a circumferential rim Edge joint with edge joint filling.
- the insulating glass unit is especially for window and facade cladding determined in the construction sector, but can also be used as Vehicle window are used.
- Such an insulating glass unit must be subject to considerable thermal stress for example solar radiation at high outside temperatures on the one hand and from low outside temperatures absorb deep frost on the other hand.
- thermal stress for example solar radiation at high outside temperatures on the one hand and from low outside temperatures absorb deep frost on the other hand.
- the insulating glass unit to which the invention relates is designed to be sound and / or heat insulating.
- the distance between the two glass panes must be small Tolerances are set up and adhered to. That applies also for the edge joint.
- the sealing will be high Requirements.
- the edge joint filling serves that from a reaction adhesive or a plastic consists.
- Insulating glass units of the construction described are one Outstanding mass product of industrial series production. You must be set up to modern automatic manufacturing equipment with high Pieces can be manufactured in the unit of time and safe and with a long service life all requirements of very complex load spectrum are sufficient.
- an edge joint filling is provided, which also works as a spacer. it consists of Reaction adhesive strands.
- the manufacturing process works that the reaction adhesive strands over the edge of the disc survives with a bead that is in a special Manufacturing stage removed by mechanical rework must become. This is complex in terms of production technology and can be improved with regard to long-term tightness. It is used to improve the tightness Insulating glass units also known (DE 27 52 542 C2), for the spacers use plastics that one thermal after-treatment require, which is also expensive is.
- Another insulating glass unit (EP 0 430 889 A2) a spacer designed as a hollow profile is provided.
- an edge joint filling made of a synthetic resin adhesive arranged.
- the hollow profile has a moisture absorbent Substance and towards the space between the panes Holes on.
- a water vapor and gas impermeable coating for example a metallic coating, which is expensive to apply is.
- the invention is based on the technical problem Insulating glass unit of the construction described at the beginning create that as part of an automated industrial series production can be easily manufactured can and the complex stress spectrum like it described at the beginning, is sufficient in the long term.
- the TPO plastics include, for example, ethylene-propylene-diene terpolymer / polypropylene (EPDM / PP), or natural rubber / polypropylene (NR / PP), or butyl rubber / polypropylene (IIR / PP) and alloys or mixtures thereof.
- EPDM / PP ethylene-propylene-diene terpolymer / polypropylene
- NR / PP natural rubber / polypropylene
- IIR / PP butyl rubber / polypropylene
- the invention is based on the knowledge that from the in the group of TPO plastics listed in feature 1.1) some for the construction of the edge fillings Insulating glass units that described above are exposed to complex stress spectrum are.
- the individual members of the group exist on their part from a number of special variants that the Plastic chemistry pretends.
- the one for the manufacture of insulating glass units at the entrance described construction well usable thermoplastic Plastic can be selected when choosing (in the laboratory) in accordance with selection criterion 1.2) becomes. This applies both to the embodiment according to Claim 1 as well as for the embodiment according to Claim 2.
- the edge joint filling can be extruded and thereby as such according to the desired geometry be shaped.
- any rework is omitted because according to Feature 1.3) an end face is formed.
- she is in the finished insulating glass unit between the inner pane and outer pane visible and forms with at least one of these panes has a smooth, flush finish. Surprisingly, tight tolerances can be met exactly become.
- Flush with one of the glass panes is set up when the other glass pane with a Projecting edge. Close both glass panels flush ends, the edge joint filling consisting of the TPO also closes flush with the edges of the two glass panes from.
- the final view surface that is used when extruding or Continuous casting was achieved within the scope of the invention a double function. She has been under the influence the surface tension of the thermoplastic when extruding and when leaving the extruder die practically pore-free and improved thereby the diffusion tightness, not only serves as Visible area.
- the teaching of the invention permits two fundamentally identical embodiments, which are specified in detail, however, according to different uses.
- the insulating glass unit is preferably equipped with an inner pane, an outer pane and a spacer which runs around the edge to form the edge joint and is designed as a hollow profile, as well as the additional edge joint filling.
- the edge joint filling is expediently connected not only to the glass panes, but also to the hollow profile. This can be glued in turn.
- a particular advantage of the invention is that a gas and water vapor permeable coating, in particular a metal coating, is no longer required on the surface of the hollow profile facing the edge joint filling.
- the selection or mixture will be made so that the TPO material has an argon permeability of> 100 ml mm / m 2 d bar at 20 ° C.
- the inner pane and the outer pane are flush or one of the panes protrudes with a guide edge.
- vehicle window means in particular motor vehicle windows for fast-moving motor vehicles which are exposed to high dynamic loads from air forces and when the motor vehicle doors equipped with the insulating glass are slammed shut.
- the TPO plastics used in the invention have no polar character. Nonetheless and surprisingly, there’s a chance at one insulating glass unit according to the invention the TPO plastic from group 1.1) or mixtures thereof in accordance with the Selection criterion 1.2) for a pressure / heat connection to select. High adhesion between the edge joint filling and the glass panes are always accessible. If one such liability is sufficient depends on the selected TPO plastic, but also from the surface of the bottom Under certain circumstances, printed glass panes.
- the TPO plastic from group 1.1) or Mixtures thereof in accordance with selection criterion 1.2) for a pressure / heat connection with intermediate connection an adhesion promoter applied to the glass panes the group "polyurethane systems, polyethylene and polypropylene systems, Ethylene vinyl acetates "or mixtures to choose from.
- the liability of the edge joint filling for Glass should be> 5 N / mm.
- the liability of Edge joint filling to the hollow profile is cohesive.
- the edge joint filling can consist of two strands of different TPO plastics from group 1.1) exist, of which at least one in accordance with the Selection criterion 1.2) is selected. You can get in the way of coextrusion.
- the invention with distance-defining hollow profile can through the hollow profile and the edge joint filling Be coextruded.
- the insulating glass units according to the invention are sufficient for a long time the complex range of stresses described at the beginning pass the creep tests without further ado according to DIN 1286, part 1 and part 2. You but there are also the usual climate change tests, Low temperature tests, high temperature tests and pressure swing tests.
