Abstract

The procedure consists of applying an inner spacing strip (14) of a structured thermoplastic resin film 10-15 mm wide between the panes of glass (10, 12) round the whole of their periphery. An overlapping seal (20) with a valve for connecting to a suction unit is then fitted round the edge of assembly and the air is extracted from between the panes of glass. The procedure consists of applying an inner spacing strip (14) of a structured thermoplastic resin film 10-15 mm wide between the panes of glass (10, 12) round the whole of their periphery. An overlapping seal (20) with a valve for connecting to a suction unit is then fitted round the edge of assembly and the air is extracted from between the panes of glass. The assembly is then heated to a temperature of about 130[deg]C to melt the thermoplastic resin film and convert it into an adhesive film that sticks the glass panes together. Once it has cooled the overlapping seal is removed, leaving a panel with two or more panes of glass with a vacuum between.

Description

La présente invention concerne les ensembles à multiple vitrage utilisésThe present invention relates to multi-glazed assemblies used

pour les portes et fenêtres de bâtiments dans le but d'obtenir une bonne isolation thermique et concerne en particulier un procédé de fabrication d'un ensemble à double  for doors and windows of buildings for the purpose of obtaining good thermal insulation and concerns in particular a method of manufacturing a double set

vitrage.glazing.

Les ensembles comportant deux vitres séparées par un film en matière plastique transparent sont utilisés depuis très longtemps, et sont connus généralement sous le nom de verres feuilletés.  Sets comprising two panes separated by a transparent plastic film have been used for a very long time, and are generally known as laminated glasses.

De façon à améliorer l'isolation thermique et phonique des portes et fenêtres, on a eu l'idée d'utiliser un ensemble à double vitrage dans lequel les deux vitres sont séparées par une couche d'air qui peut avoir une épaisseur de 6mm. Malheureusement, l'air n'est pas un isolant thermique parfait et un tel ensemble à double vitrage présente quand même un coefficient de conduction thermique important (K = 1,3) qui ne permet pas d'assurer une isolation thermique parfaite.  In order to improve the thermal and sound insulation of doors and windows, it was thought to use a double-glazed unit in which the two panes are separated by a layer of air that can have a thickness of 6mm. Unfortunately, air is not a perfect thermal insulator and such a double-glazed unit still has a significant coefficient of thermal conduction (K = 1.3) which does not provide a perfect thermal insulation.

C'est pourquoi on a songé à utiliser des ensembles à double vitrage dans lesquels les deux vitres sont séparées par un espace vide d'air ou de tout autre gaz. Un ensemble à double vitrage de ce type présente un coefficient de conduction thermique très faible (K = 0,5) qui permet d'obtenir une très bonne isolation thermique de l'ensemble.  This is why we thought of using double-glazed units in which the two panes are separated by an empty space of air or any other gas. A double-glazed assembly of this type has a very low thermal conductivity coefficient (K = 0.5) which makes it possible to obtain a very good thermal insulation of the assembly.

Le procédé de fabrication d'un tel ensemble consiste à disposer un espaceur, généralement des billes d'acier entre les deux vitres et à placer un mastic entre les deux vitres à la périphérie de l'ensemble. Une valve est insérée dans la couche de mastic de manière à pouvoir y connecter une machine à faire le vide. Lorsque le vide a été installé entre les deux vitres par aspiration de l'air, la valve est retirée de la couche de mastic. Il est clair qu'un tel procédé utilisant une valve intégrée dans la couche assurant l'étanchéité est très difficile à mettre en oeuvre dans la mesure où le retrait de la valve sans provoquer d'entrée d'air pose de gros problèmes qui rendent le procédé difficilement industrialisable.  The method of manufacturing such an assembly consists in arranging a spacer, generally steel balls between the two panes, and placing a sealant between the two panes at the periphery of the assembly. A valve is inserted into the sealant layer so that a vacuum machine can be connected to it. When the vacuum has been installed between the two panes by suction of the air, the valve is removed from the sealant layer. It is clear that such a method using a valve integrated in the sealing layer is very difficult to implement insofar as the removal of the valve without causing air entry poses major problems that make the process difficult to industrialize.

C'est pourquoi le but de l'invention est de réaliser un procédé de fabrication d'un ensemble à multiple vitrage dans lequel la mise sous vide de l'espace entre les vitrages est effectuée extérieurement à l'ensemble et ne nécessite pas l'installation et le retrait problématique d'une valve à la périphérie de l'ensemble.  This is why the object of the invention is to provide a method of manufacturing a multi-glazed assembly in which the evacuation of the space between the glazings is effected externally to the assembly and does not require the installation and problematic removal of a valve at the periphery of the assembly.

L'objet de l'invention est donc un procédé de fabrication d'un ensemble à multiple vitrage composé d'au moins deux vitres séparées par un espace vide d'air ou de tout autre gaz, l'espacement entre les deux vitres étant maintenu par des éléments intercalaires, et consistant à disposer un film périphérique structuré en résine thermoplastique entre les deux vitres sur toute la périphérie de l'ensemble, disposer un joint cavalier sur tout le pourtour de l'ensemble de façon à obtenir un nouvel ensemble étanche, le joint comportant une valve adaptée pour y connecter une machine à faire le vide, faire le vide en retirant l'air entre les vitres au moyen de la machine à faire le vide, chauffer le nouvel ensemble de manière à fluidifier le film en résine thermoplastique et le transformer en un film adhésif reliant les vitres, et, après refroidissement, retirer le joint cavalier pour obtenir l'ensemble à multiple vitrage comportant un espace vide d'air et de tout gaz entre les deux vitres.  The object of the invention is therefore a method of manufacturing a multi-glazed assembly composed of at least two panes separated by an empty space of air or any other gas, the spacing between the two panes being maintained by interposed elements, and consisting in arranging a thermoplastic resin structured peripheral film between the two panes all around the periphery of the assembly, having a jumper joint all around the periphery of the assembly so as to obtain a new sealed assembly, the seal having a valve adapted to connect a vacuum machine, to evacuate by removing the air between the panes by means of the vacuum machine, to heat the new assembly so as to fluidize the thermoplastic resin film and transforming it into an adhesive film connecting the panes, and, after cooling, removing the jumper seal to obtain the multi-glazed assembly having an empty space of air and any gas e between the two windows.

Les buts, objets et caractéristiques de l'invention apparaîtront plus clairement à la lecture de la description qui suit faite en référence aux dessins dans lesquels: É La figure 1 représente un ensemble à double vitrage susceptible d'être fabriqué selon le procédé de l'invention, É La figure 2 représente une coupe de l'ensemble à double vitrage illustré sur la figure 1 et un grossissement d'une portion du film structuré, le joint périphérique étant mis en place avant l'opération de mise sous vide, et É La figure 3 représente une coupe de l'ensemble à double vitrage illustré sur la figure après que le vide a été 5 réalisé ainsi qu'un grossissement d'une portion du film périphérique.  The objects, objects and features of the invention will appear more clearly on reading the following description with reference to the drawings in which: FIG. 1 represents a double-glazed assembly that can be manufactured according to the method of FIG. FIG. 2 shows a cross-section of the double glazed assembly shown in FIG. 1 and a magnification of a portion of the structured film, the peripheral seal being set up before the vacuum operation, and Figure 3 shows a sectional view of the double-glazed assembly shown in the figure after the vacuum has been achieved as well as a magnification of a portion of the peripheral film.

Un ensemble à double vitrage fabriqué selon le procédé de l'invention illustré sur la figure 1 comprend une première vitre 10 et une deuxième vitre 12 séparées par un espace dans lequel le vide a été fait. Un film périphérique 14 d'une largeur de 10 à 15mm a été disposé sur toute la périphérie entre les deux vitres et assure l'étanchéité de manière à empêcher l'air de pénétrer entre les deux vitres. Des éléments intercalaires (non montrés) sont disposés entre les deux vitres de façon classique pour assurer l'espacement entre les deux vitres et empêcher qu'elles se plaquent l'une sur l'autre à cause de la pression due au vide entre les deux vitres.  A double glazed unit manufactured according to the method of the invention illustrated in Figure 1 comprises a first pane 10 and a second pane 12 separated by a space in which the vacuum has been made. A peripheral film 14 with a width of 10 to 15 mm has been disposed over the entire periphery between the two panes and provides a seal so as to prevent air from entering between the two panes. Interleaved elements (not shown) are arranged between the two panes in a conventional manner to ensure the spacing between the two panes and prevent them from sticking to one another due to vacuum pressure between the two panes. windows.

Le film périphérique 14 est une résine thermoplastique se fluidifiant sous l'effet de la chaleur. Dans un mode de réalisation préféré, le film périphérique est un co-polymère de vinyl-acétate d'éthylène avec un agent de transformation connu sous le sigle EVA.  The peripheral film 14 is a thermoplastic resin which becomes fluid under the effect of heat. In a preferred embodiment, the peripheral film is a co-polymer of ethylene vinyl acetate with a transformation agent known as EVA.

A noter que si l'ensemble comprend plus de deux vitres, il faut prévoir un film périphérique séparant les deux vitres 25 de chaque couple de vitres consécutives.  Note that if the assembly comprises more than two panes, it is necessary to provide a peripheral film separating the two panes 25 of each pair of consecutive panes.

Le procédé de fabrication selon l'invention consiste à appliquer une bande de film périphérique 14 rendu adhésif sur toute la périphérie de la première vitre. Un ou plusieurs éléments intercalaires sont ensuite placés sur la première vitre 10 de façon à éviter l'écrasement d'une vitre sur l'autre lorsque le vide sera réalisé. Puis la deuxième vitre 12 est placée au-dessus du film périphérique 14 et des éléments intercalaires (non montrés) de façon à se superposer à la première vitre. A Noter que le film périphérique est structuré comme illustré sur le grossissement de la figure 1, c'est à dire qu'il n'est pas plaqué contre les deux vitres mais laisse subsister des interstices 16 ou 18.  The manufacturing method according to the invention consists in applying a strip of peripheral film 14 made adhesive over the entire periphery of the first pane. One or more intermediate elements are then placed on the first pane 10 so as to avoid the crushing of one pane on the other when the vacuum will be realized. Then the second pane 12 is placed above the peripheral film 14 and the intermediate elements (not shown) so as to be superimposed on the first pane. Note that the peripheral film is structured as shown in the magnification of Figure 1, that is to say, it is not pressed against the two panes but leaves gaps 16 or 18.

Un joint cavalier adhésif 20 généralement en néoprène est alors placé tout autour de l'ensemble à double vitrage et vient se coller, grâce à un adhésif, sur la périphérie de chacune des vitres de façon à assurer une étanchéité parfaite.  A generally neoprene adhesive jumper 20 is then placed all around the double-glazed assembly and adheres, by means of an adhesive, to the periphery of each of the panes so as to ensure perfect sealing.

A noter que le joint 20 comporte une rainure en son milieu qui fait face à la tranche du film périphérique 14.  Note that the seal 20 has a groove in its middle which faces the edge of the peripheral film 14.

Cette rainure a pour but de faciliter la mise en place d'une valve introduite dans le joint au droit de la rainure. Une pompe à vide est ensuite raccordée à la valve (non montrée).  This groove is intended to facilitate the introduction of a valve introduced into the seal at the groove. A vacuum pump is then connected to the valve (not shown).

On procède alors à la mise sous vide de l'espace entre les deux vitres au moyen de la pompe à vide qui aspire l'air par la valve installée dans le joint de néoprène 20, l'air entre les deux vitres étant aspiré grâce aux interstices 16, 18 entre le film périphérique 14 et les vitres.  The space between the two panes is then evacuated by means of the vacuum pump which draws air through the valve installed in the neoprene gasket 20, the air between the two panes being sucked by means of interstices 16, 18 between the peripheral film 14 and the panes.

Après que l'ensemble à double vitrage se trouvant à l'intérieur du joint de néoprène 20 a été mis sous vide, il est chauffé à une température d'environ 130 . A cette température, le film périphérique 14 se fluidifie et vient adhérer sur les parois des vitres 10 et 12, les interstices 16 et 18 disparaissant au cours de cette transformation. A noter que la distance séparant les deux vitres diminue légèrement au cours de cette étape du fait que le film périphérique ne laisse subsister aucun interstice après qu'il a été fluidifié sous vide.  After the double glazed assembly within the neoprene seal 20 has been evacuated, it is heated to a temperature of about 130. At this temperature, the peripheral film 14 is fluidized and adhere to the walls of the panes 10 and 12, the interstices 16 and 18 disappearing during this transformation. Note that the distance separating the two panes decreases slightly during this step because the peripheral film leaves no gap after it has been fluidized under vacuum.

Après refroidissement de l'ensemble et retrait du joint de néoprène, l'ensemble est refroidi et nettoyé. A noter que la difficulté de retirer la valve n'existe plus dans la mesure où cette valve est à l'extérieur de l'ensemble à double vitrage lorsque le vide a été installé entre les vitres.  After cooling the assembly and removing the neoprene seal, the assembly is cooled and cleaned. Note that the difficulty of removing the valve no longer exists insofar as this valve is outside the double-glazed unit when the vacuum has been installed between the panes.

Le procédé de fabrication selon l'invention, permet de réaliser sans trop de difficulté des ensembles à multiple vitrage présentant une très bonne isolation grâce à un coefficient de conduction K = 0,5 au lieu de K = 1,3 pour un ensemble traditionnel. Ainsi une épaisseur de vitre de 8mm permet d'obtenir une isolation équivalente à celle d'un vitrage traditionnel où l'épaisseur des vitres est supérieure à 30mm.  The manufacturing method according to the invention makes it possible to achieve, without much difficulty, multi-glazed assemblies with very good insulation thanks to a conduction coefficient K = 0.5 instead of K = 1.3 for a conventional assembly. Thus a glass thickness of 8mm provides insulation equivalent to that of a traditional glazing where the thickness of the glass is greater than 30mm.
