Abstract
The invention relates to a spacer for multiple-glazed insulating glazing, comprising a base element (5), which has two parallel contact surfaces (9, 11) for the glazing panels (1, 3), and an adhesive surface (19) which is turned away from the inner space of the glazing unit and connects the two contact surfaces. The base element (5) is made of fibreglass reinforced plastic. Said spacer is characterized in that a metal foil (21) is glued against all of the adhesive surface (19), and in that by selecting the proportion of fibreglass in the plastic matter of the base element it is possible to match the coefficients of thermal expansion of the base element and the metal foil. This type of spacer ensures especially good leak tightness and lasting bonding between the plastic spacer and the metal foil, and between said metal foil and the sealant between the glazing panels.
Description
SPACER FOR MULTIPLE-GLAZED INSULATING GLAZING
The invention relates to a spacer for a multiple pane insulating glazing assembly.
Such spacers are especially utilized for double pane insulating glass in order to provide a spaced connection of the two individual glass panes. Moreover, they serve the function of sealing the interior space between the panes from the ambient so that, for example, a gas introduced therein cannot escape. Furthermore, by an appropriate configuration, they are intended to prevent moisture or air from the ambient from penetrating into the interior space, which would cause the glass panes to become opaque over a longer period of time.
However, many spacers of the prior art present the disadvantage that. they exhibit a higher thermal conductivity compared to the gas or air enclosed in the interior space. I3ecause of this, the inner glass pane is strongly cooled :in the immediate region of the spacer when outside temperatures are low, thus resulting in unwanted moisture condensation at these locations.
An improvement of the insulating properties of spacers has been obtained by the use of a plastic material. However, this presents the problem that the adhesive and sealing mass introduced between the edges of the two glass panes, usually polysulphide or silicone, poorly adheres to the plastic material since these adhesives were usually developed especially for metallic spacers. This results in leakage between the interior space and the ambient as well as hollow spaces between the spacer and the sealing mass where moisture can collect and further deteriorate the seal.
It is further known to reinforce the strength of the plastic material by the use of glass fiber or mineral powder reinforcements, e.g. according to US-A-5 260 112 or EP-B-127 739.
According to the latter patent specification, on which the preamble is based, the free surface of the spacer in the assembled condition is provided with a metal coating for the purpose of inhibiting the diffusion of water vapor.
The metal layer is coextruded with the spacer. This coating method only allows a poor adhesion of the metal layer, particularly in the case of great temperature variations.
This is especially important if, in contrast to the spacer according to this patent specification, a sealing mass is applied around the free part of the spacer, i.e. around the metal layer, which should adhere both to the metal layer and to the glass panes in order to obtain a good and durable stability overall.
On the background of this prior art, it is the object of the present invention to provide a spacer which, having a low thermal conductivity, allows a reliable adhesive bond and seal and in particular, a good adherence of the metal layer to the plastic body.
According to the present invention there is provided a spacer for a multiple glass pane insulating glazing assembly, comprising a base body (5) having two mutually parallel contact surfaces (9, 11) for glass panes (1, 3) and an adhesion surface (19) which connects the two contact surfaces and faces away from the interior space of 2a the glazing, said base body (5) consisting of glass-fiber reinforced plastic material, and a metal layer (21) being disposed on the adhesion surface (19), characterized in that the metal layer (21) is bonded or vapor-deposited on the entire adhesion surface (19) and the proportion of short glass fibers in the plastic material is selected such that the coefficient of thermal expansion of the base body (5) corresponds to that of the metal layer (21).
T:\KG\TEXTE\BESCHR\25899US.DOC CE) The invention will now be explained in more detail with reference to the single drawing which shows a cross-section of the edge area of a double glazing.
Two glass panes 1, 3, of which only sections are shown, are disposed in parallel to and at a distance from each other by means of a spacer 5. This spacer 5 extends along the non-represented edges of the two glass panes l, 3 so as to form an interior space 7 between the glass panes. This interior space 7 is usually filled with air and preferably with gas.
The spacer 5 includes contact surfaces 9 and 11, each of which faces one of glass ~>anes 1 and 3, respectively.
In order to seal interior space 7, the contact surfaces 9 and 11 are provided with groove-shaped recesses 13 and 15, respectively, into which a p~_astic sealing mass is introduced, e.g. a butyl compound such as butyl rubber (hereinafter shortly called butyl). Recesses 13 and 15 always ensure a minimum contact surface and minimum thickness of butyl on the glass panes.
An outwardly facing, free surface 19 (hereinafter referred to as the adhesion ;surface) extends from contact surface 9 to exterior surface 11. This adhesion surface 19 has an essentially U-shaped cross-section while its legs, seen in cross-section, are tapered from contact surfaces 9 outwards.
A thin metal. foil 21, more particularly an aluminum foil, is applied to this adhesion surface 19. The bond is ensured by a non-gassing adhesive 23, e.g. a PUR-hotmelt T:\KG\TEXTE\BESCHA\25899US.DOC CE) adhesive curing with humidity. If a conventional adhesive is used, gases diffuse through the spacer into the interior space 7, where they :may lead to a chemical condensate on the glass pane.
It is also possible to obtain a good adhesion of the metal layer by vapor deposition, and other metals than aluminum or steel can also be used in the process.
In order to obtain a good and durable bond of the metal foil or metal layer to the plastic body, the difference of the temperature expansion coefficients of both parts should be as small as possible; otherwise, the foil may chip off. In order to achieve the best possible adjustment of both thermal expansion coefficients, an appropriate amount of glass fibers is admixed to the plastic material. It is evident that according to the type of foil, e.g. aluminum c>r steel, a smaller or greater amount of short glass fibers is admixed, preferentially already to the plastic granu7_ate. Furthermore, the amount admixed also depends on the kind of plastic material.
In order to allow a good processing, it is advantageous to utilize a thermoplastic plastic material, e.g. a SAN plastic material comprising glass fibers from BASF known under the trademark LURAN. If such a plastic material and an aluminum foi.L are used, the glass fiber proportion amounts to approx. 350.
An adhesive resp. seali:zg mass 27, preferably polysulphide or silicone, is introduced into the space 25 defined by the two glass panes 1 and 3 and adhesion surface 19 in order to cement the two glass panes to the T:\KG\TEXTE\BESCHR\25899US.DOC CE) spacer, on one hard, and in order to obtain a further sealing of interior space 7, on the other hand.
Since adhesion surface 19 is completely covered outwardly by metal foil 21, this sealing mass 27 does not come into direct contact with the plastic material of the spacer but with the metal. Since the adhesion of polysulphide or silicone to metal is significantly greater than to plastic, an improved adhesive bond of the individual parts is obtained. Furthermore, sealing mass 27 does no longer separate from foil 21, so that the formation of hollow spaces i~. prevented.
The figure further shows that spacer 5 comprises a hollow space which, viewed in cross-section, is enclosed by the two contact surfaces ~j, 11, adhesion surface 19, and by a wall 31 facing interior space 7. The good stability of the spacer on account of the glass fibers is thereby further increased. F?referably, a desiccant 33, e.g. silica gel, molecular s__eves, or a mixture of the two means, is introduced into this hollow space 29 in order to draw moisture/water vapor oui~ of interior space 7. In order to establish a connect_i.on between interior space 7 and hollow space 29, wall 31 is provided with openings 35.
The figure does not show that in the longitudinal direction, spacers 5 are bent at an angle of 90° at the corners of the glass panes. This is possible since the base body is made of a thermoplastic material. This allows either a corner connection to be used or to bend a corner.
T:\KG\TE7iTE\BESCHR\25E99US.DOC CE) The figure further shows that the longitudinal edges of metal foil 21 do not come into contact with the adjacent glass panes 1 resp. 3. Thereby it is ensured that an insulating gap filled with sealing mass 27 is formed between the glass pane and heat-conducting metal foil 21. In addition, the transmission of heat or cold by metal foil 21 is reduced by the fact that the thickness of the metal foil is smaller than 0.1 mm, and that the path between the two glass panes 1 and 3 is increased by the U-shaped or V-shaped configuration of adhesion surface 19.
Other shapes of the plastic profile are also conceivable.
