Abstract
Description
La présente invention concerne un produit feuilleté a base de verre, destiné a permettre la réalisation de vitrages, ou analogues, a la fois parfaitement transparents et résistant aux chocs. The present invention relates to a laminated product based on glass, intended to allow the production of glazing, or the like, both perfectly transparent and impact resistant.
On utilise couramment dans ce but des verres feuilletés comportant un certain nombre de feuilles de verre, soudées entre elles, en un produit unitaire parfaitement transparent. Toutefois, le verre est un produit lourd et la superposition d'un grand nombre de feuilles s'avère souvent nécessaire pour résister à des impacts spécifiques et particulièrement violents. On peut atteindre ainsi des épaisseurs, et surtout des poids, prohibitifs dans certains cas d'utilisation. For this purpose, laminated glasses commonly comprising a number of glass sheets, welded together, are used in a perfectly transparent unitary product. However, glass is a heavy product and the superimposition of a large number of sheets is often necessary to resist specific and particularly violent impacts. We can thus reach thicknesses, and especially weights, prohibitive in certain cases of use.
Pour obtenir un produit moins lourd et moins épais, il a été tenté d'associer le verre a d'autres matériaux plus légers, tels que le polycarbonate, ayant en outre des propriétés de resistance mécanique différentes. In order to obtain a lighter and less thick product, attempts have been made to combine glass with other lighter materials, such as polycarbonate, which also have different mechanical resistance properties.
La fixation des differentes feuilles les unes aux autres a alors posé un gros problème, car le polycarbonate s'est montré incompatible avec le butyral de polyvinyle habituellement utilisé pour lier les feuilles de verre entre elles. I1 est alors nécessaire de maintenir les différentes feuilles en contact les unes avec les autres par des moyens mécaniques. Fixing the different sheets to each other then posed a big problem, because polycarbonate has been shown to be incompatible with the polyvinyl butyral usually used to bond the glass sheets together. I1 is then necessary to maintain the different sheets in contact with each other by mechanical means.
La présente invention a pour but de remédier a cet inconvénient en réalisant un produit feuilleté composite transparent, qui présente des qualités de résistance suffisante pour lui permettre de subir des chocs répétés tout en n'ayant qu'une épaisseur et un poids relativement réduits. The object of the present invention is to remedy this drawback by producing a transparent composite laminated product, which has qualities of resistance sufficient to allow it to undergo repeated impacts while having only a relatively reduced thickness and weight.
Cette invention a en effet pour objet un produit feuilleté composite transparent, qui comprend au moins une feuille de polycarbonate uniformément soudée sur une feuille de verre par une feuille de butyral de polyvinyle qui a fondu, le polycarbonate et le butyral de polyvinyle étant préalablement devenus compatibles. The subject of this invention is in fact a transparent composite laminated product, which comprises at least one sheet of polycarbonate uniformly welded to a glass sheet by a sheet of polyvinyl butyral which has melted, the polycarbonate and the polyvinyl butyral having previously become compatible. .
La feuille de butyral de polyvinyie est une feuille dont les propriétés physiques ont été modifiées par un passage dans un bain chimique approprié, suivi d'un traitement thermique, et qui est devenue compatible avec le polycarbonate. Polyvinyl butyral sheet is a sheet whose physical properties have been modified by passing through an appropriate chemical bath, followed by heat treatment, and which has become compatible with polycarbonate.
Les différentes feuilles qui constituent le produit sont, par suite, intimement et uniformément soudées les unes aux autres, de sorte qu'elles sont parfaitement et totalement transparentes et peuvent même résister, dans certaines épaisseurs, aux impacts de balles de fort calibre, ou analogues. The different sheets which constitute the product are, therefore, intimately and uniformly welded to each other, so that they are perfectly and completely transparent and can even withstand, in certain thicknesses, the impacts of large caliber bullets, or the like. .
La feuille de polycarbonate peut également être une feuille traitée chimico-thermiquement et devenue compati ble avec le butyral de polyvinyle, au moins sur sa face de contact avec ce dernier. The polycarbonate sheet can also be a chemically thermally treated sheet which has become compatible with polyvinyl butyral, at least on its contact face with the latter.
Selon les applications, le produit feuilleté peut comporter divers nombres de feuilles de verre et de polycarbonate soudées les unes aux autres. De préférence le produit comporte une feuille de verre sur chacune de ses faces extrêmes, un nombre variable de feuilles de verre et de polycarbonate étant intercalées entre ces deux feuilles extrêmes, et toutes les feuilles étant soudées les unes aux autres par des feuilles de butyral de polyvinyle qui ont fondu. Depending on the applications, the laminated product may include various numbers of glass and polycarbonate sheets welded together. Preferably, the product comprises a glass sheet on each of its end faces, a variable number of glass and polycarbonate sheets being interposed between these two end sheets, and all the sheets being welded to each other by butyral sheets of polyvinyl that have melted.
De même les épaisseurs des feuilles de verre et de polycarbonate peuvent varier selon la destination du produit feuilleté. Likewise, the thicknesses of the glass and polycarbonate sheets may vary depending on the destination of the laminated product.
Par ailleurs la soudure entre une feuille de verre et la feuille de polycarbonate adjacente peut être effectuée à l'aide d'uneou de plusieurs feuilles de butyral de polyvinyle traitées, selon la résistance désirée. La soudure du polycarbonate traité ou non sur le verre, ou sur une autre feuille de polycarbonate, s'effectue de la manière habituellement utilisée pour la soudure de deux feuilles de verre, au moyen d'une feuille de butyral de polyvinyle. Furthermore, the welding between a glass sheet and the adjacent polycarbonate sheet can be carried out using one or more treated polyvinyl butyral sheets, according to the desired resistance. The welding of the treated or untreated polycarbonate on the glass, or on another sheet of polycarbonate, is carried out in the manner usually used for the welding of two sheets of glass, using a sheet of polyvinyl butyral.
La figure unique du dessin annexé montre, en coupe transversale, un produit feuilleté selon l'invention. The single figure of the accompanying drawing shows, in cross section, a laminated product according to the invention.
Cette figure montre en effet une plaque de verre 1, une plaque de polycarbonate 2, ainsi qu'une feuille de butyral de polyvinyle fondue 4 qui est interposée entre ces deux plaques et les soude entre elles. This figure shows indeed a glass plate 1, a polycarbonate plate 2, as well as a molten polyvinyl butyral sheet 4 which is interposed between these two plates and welds them together.
Selon l'invention la feuille de butyral de polyvi nyle utilisee est une feuille qui a été traitée chimicothermiquement au préalable et est ainsi devenue compatible avec le polycarbonate. Cette feuille traitée est mise en contact avec le polycarbonate, puis pressée à chaud avec celui-ci contre la feuille de verre de façon à être soudée sur elle. According to the invention, the polyvinyl butyral sheet used is a sheet which has been chemothermally treated beforehand and has thus become compatible with polycarbonate. This treated sheet is brought into contact with the polycarbonate, then hot pressed with the latter against the glass sheet so as to be welded to it.
Une seconde feuille de verre 6 est également soudée sur la face de la feuille de polycarbonate 2, qui est opposée à la feuille de verre 1 au moyen d'une seconde feuille de butyral de polyvinyle qui a été préalablement traitée de la même manière que la première. Sous l'effet de la pression et de la chaleur la ou les feuilles de butyral fondent et se soudent étroitement et uniformément à la fois à la feuille de verre et à la feuille de polycarbonate. A second glass sheet 6 is also welded to the face of the polycarbonate sheet 2, which is opposite to the glass sheet 1 by means of a second polyvinyl butyral sheet which has been previously treated in the same manner as the first. Under the effect of pressure and heat the butyral sheet or sheets melt and weld tightly and uniformly both to the glass sheet and to the polycarbonate sheet.
Le produit formé par ces trois feuilles est, bien entendu, parfaitement transparent et il présente une résistance importante aux chocs violents tout en ayant une épaisseur et un poids nettement inférieurs à ceux qui seraient nécessaires pour obtenir une résistance analogue avec les feuilles de verre habituelles. The product formed by these three sheets is, of course, perfectly transparent and it has a significant resistance to violent shocks while having a thickness and a weight clearly lower than those which would be necessary to obtain a similar resistance with the usual glass sheets.
En outre la feuille de polycarbonate est protégée des contacts extérieurs par les deux feuilles de verre, ce qui limite les risques de détérioration du produit. In addition, the polycarbonate sheet is protected from external contacts by the two glass sheets, which limits the risks of product deterioration.
Selon une variante de réalisation la feuille de polycarbonate est une feuille qui a été traitee chimicothermiquement au moins sur sa face de contact avec le butyral. De préférence cette feuille est passée tout en tière dans un bain chimique approprié, puis subit un traitement thermique et devient ainsi, -sur toute sa sur face, pratiquement compatible avec le butyral de polyvinyle. Avec de telles feuilles de polycarbonate soudées au moyen de feuilles de butyral, également traitées, on peut obtenir des feuilletés de résistance extrêmement élevée. According to an alternative embodiment, the polycarbonate sheet is a sheet which has been chemothermally treated at least on its contact face with the butyral. Preferably, this sheet is passed entirely in a suitable chemical bath, then undergoes a heat treatment and thus becomes, over its entire surface, practically compatible with polyvinyl butyral. With such polycarbonate sheets welded by means of butyral sheets, also treated, laminates of extremely high strength can be obtained.
Bien entendu les feuilles de verre 1 et 6 peuvent avoir la même épaisseur, comme représenté sur le dessin, ou avoir des épaisseurs différentes selon les applications. Of course the glass sheets 1 and 6 can have the same thickness, as shown in the drawing, or have different thicknesses depending on the applications.
Par ailleurs le produit feuilleté peut comporter un nombre plus grand de feuilles de verre et/ou de polycarbonate, ainsi qu'indiqué en traits mixtes sur la figure. Par exemple, selon un mode de réalisation, le produit comporte en plus des feuilles de verre 1 et 6 et de la feuille de polycarbonate 2, deux autres feuilles de polycarbonate 10 et 11, puis deux feuilles de verre 12 et 13, toutes ces feuilles étant soudées les unes sur les autres et formant un ensemble d'un seul bloc et parfaitement transparent. Sur la figure les feuilles 10 et 11, de même que les feuilles 12 et 13, ont des épaisseurs différentes mais il est bien évident que ces feuilles pour- raient avoir la même épaisseur. Furthermore, the laminated product may include a larger number of glass and / or polycarbonate sheets, as indicated in phantom in the figure. For example, according to one embodiment, the product further comprises glass sheets 1 and 6 and the polycarbonate sheet 2, two other polycarbonate sheets 10 and 11, then two glass sheets 12 and 13, all of these sheets being welded to each other and forming a unitary unit and perfectly transparent. In the figure, the sheets 10 and 11, as well as the sheets 12 and 13, have different thicknesses, but it is obvious that these sheets could have the same thickness.
De la meme manière la répartition des feuilles de polycarbonate et de verre pourrait être différente, ainsi que leur nombre, de façon à adapter le produit à l'application à laquelle il est destiné et notamment aux dimensions du vitrage et à l'importance des chocs à prévoir. In the same way the distribution of the polycarbonate and glass sheets could be different, as well as their number, so as to adapt the product to the application for which it is intended and in particular to the dimensions of the glazing and the importance of the shocks predictable.
Le produit peut ainsi être adapté à la réalisation de vitrages de types très divers, que ce soit des verrières, des écrans de protection, ou autres, et qu'ils soient destinés a prévenir des chutes ou à protéger contre des effractions, des agressions à main armée, ou analogues. The product can thus be adapted to the production of glazing of very different types, whether it be canopies, protective screens, or the like, and whether they are intended to prevent falls or to protect against break-ins, attacks to armed force, or the like.
