Description

VERRE AMELIORE POUR VEHICULE AUTOMOBILE UTILISE
EN TANT QUE VERRE DE SECURITE ANTI-VOL
La présente invention concerne un verre amélioré pour véhicules, apte à être utilisé en tant que verre anti-vol.IMPROVED GLASS FOR A MOTOR VEHICLE USED
AS ANTI-THEFT SECURITY GLASS
The present invention relates to an improved glass for vehicles, suitable for use as an anti-theft glass.

Dans le domaine des véhicules, tels que celui des automobiles, il est souvent nécessaire d'utiliser un verre présentant une grande résistance mécanique, supérieure à celle qui est demandée par les normes en vigueur, pour garantir une meilleure sécurité vis-à-vis de voleurs s introduisant dans l'habitacle à passagers. In the field of vehicles, such as that of automobiles, it is often necessary to use a glass having a high mechanical resistance, greater than that required by the standards in force, to guarantee better safety with respect to thieves breaking into the passenger compartment.

Généralement, cette action a lieu en brisant l'une des vitres latérales au moyen de bâtons ou de barres métalliques pointues. Generally, this action takes place by breaking one of the side windows by means of sticks or pointed metal bars.

On connaît dans l'état de l'art un verre présentant une grande résistance à la rupture: un exemple est constitué par le verre résistant aux balles utilisé pour protéger le personnel courant des risques dans des bureaux ou des passagers d'automobiles dans des conditions particulièrement dangereuses. A glass with high breaking strength is known in the state of the art: an example is bullet-resistant glass used to protect current personnel from risks in offices or passengers of automobiles under conditions particularly dangerous.

L'inconvénient de ce verre résistant aux balles est son poids excessif, son coût élevé et le fait qu'il a besoin de cadres appropriés pour être monté. The disadvantage of this bullet resistant glass is its excessive weight, high cost and the fact that it needs suitable frames for mounting.

Le premier problème rencontré dans la fabrication d'un verre apte à s'opposer à des infractions par des voleurs, appelé dans ce qui suit verre anti-vol, consiste à maintenir le poids du verre à un minimum tout en lui conférant dans le même temps les meilleures caractéristiques de résistance aux impacts, tout en conservant les caractéristiques optiques de transparence et d'image réelle établies par les normes européennes ECE 43.  The first problem encountered in the manufacture of a glass capable of opposing infringements by thieves, called in what follows anti-theft glass, consists in keeping the weight of the glass to a minimum while conferring it in the same the best impact resistance characteristics, while retaining the optical characteristics of transparency and real image established by European standards ECE 43.

Ce problème a été résolu au moyen d'un verre anti-vol constitué par un complexe comportant deux feuilles de verre, entre lesquelles est ffi posée une feuille interne de polycarbonate assemblée aux feuilles de verre par des techniques de stratification et à l'aide d'adhésifs en polyuréthane. This problem was solved by means of an anti-theft glass consisting of a complex comprising two sheets of glass, between which is placed an internal sheet of polycarbonate assembled to the sheets of glass by lamination techniques and using polyurethane adhesives.

Un autre problème s'est posé quand ce verre anti-vol est utilisé dans des automobiles en raison du fait qu'en cas d'une rupture accidentelle du verre lui-même, s'il n'a pas été suffisamnent trempé, des éclats sont susceptibles d'être projetés sur les passagers et de les blesser. Another problem has arisen when this anti-theft glass is used in automobiles due to the fact that in the event of an accidental breakage of the glass itself, if it has not been sufficiently toughened, shards are likely to be thrown onto passengers and injure them.

Le but de la présente invention est de proposer un verre antivol capable de résoudre le problème susmentionné. The object of the present invention is to provide an anti-theft glass capable of solving the above-mentioned problem.

Le verre anti-vol qui fait l'objet de la présente invention est constitué par une feuille de polycarbonate interne assemblée à deux feuilles de verre externes par des techniques de stratification et à l'aide d'un adhésif en polyuréthane, la surface du verre qui est tournée vers l'intérieur de l'habitacle de l'automobile supportant un film en matière plastique transparente présentant des propriétés de résistance aux éclats. The anti-theft glass which is the subject of the present invention consists of an internal polycarbonate sheet joined to two external glass sheets by lamination techniques and using a polyurethane adhesive, the surface of the glass. which is turned towards the interior of the passenger compartment of the automobile supporting a transparent plastic film having properties of resistance to splinters.

Les deux feuilles de verre, avant d'être assemblées dans le complexe de l'invention, peuvent être également soumises à une opération de flexion de manière qu'elles puissent être utilisées pour les vitres latérales d'automobiles. The two sheets of glass, before being assembled in the complex of the invention, can also be subjected to a bending operation so that they can be used for the side windows of automobiles.

Un procédé consistant en une légère augmentation de la compression superficielle des feuilles de verre peut être mis en oeuvre soit par immersion dans un bain de sel fondu, soit par un courant de gaz tel que du dioxyde de soufre, de la vapeur sèche ou du gaz fluoré. A process consisting in a slight increase in the surface compression of the glass sheets can be carried out either by immersion in a bath of molten salt, or by a stream of gas such as sulfur dioxide, dry vapor or gas fluorinated.

De préférence, le verre anti-vol faisant l'objet de la présente invention est réalisé comme suit: une première feuille de verre flotté dont la composition est du type silice-sodium-calcaire, d'une épaisseur comprise entre 2,4 et 2,8 mm; un premier film adhésif en polyuréthane d'une épaisseur comprise entre 0,38 mm et 1,14 mn; une feuille de polycarbonate d'une épaisseur comprise entre 1,8 mm et 2,2 rrin; un second film adhésif en polyuréthane d'une épaisseur comprise entre 0,38 mm et 1,14 mm; une seconde feuille de verre flotté dont la composition est du type silice-sodium-calcaire d'une épaisseur comprise entre 2,4 mm et 2,8 mn; une couche réalisée en une matière plastique transparente d'une épaisseur qui n'est pas inférieure à 100 micromètres, pouvant résister aux éclats et déposée sur la surface du verre qui est sur le côté interne de l'habitacle de l'automobile. Preferably, the anti-theft glass forming the subject of the present invention is produced as follows: a first sheet of float glass whose composition is of the silica-sodium-limestone type, with a thickness of between 2.4 and 2 , 8 mm; a first polyurethane adhesive film with a thickness of between 0.38 mm and 1.14 min; a polycarbonate sheet with a thickness between 1.8 mm and 2.2 rrin; a second polyurethane adhesive film with a thickness of between 0.38 mm and 1.14 mm; a second sheet of float glass whose composition is of the silica-sodium-limestone type with a thickness of between 2.4 mm and 2.8 min; a layer made of a transparent plastic material with a thickness which is not less than 100 micrometers, capable of resisting splinters and deposited on the surface of the glass which is on the internal side of the passenger compartment of the automobile.

Cette couche peut être appliquée par pulvérisation ou vernissage d'une couche de composition chimique appartenant à la famille des mélanges polymères IPN "Interpenetrated Polymer Network" du type acrylique-polyuréthane,et par polymérisation sur site de la composition. This layer can be applied by spraying or varnishing a layer of chemical composition belonging to the family of IPN "Interpenetrated Polymer Network" polymer blends of the acrylic-polyurethane type, and by site polymerization of the composition.

A la place de cette couche en matière plastique, on peut utiliser un film auto-adhésif réalisé en polyester, optiquement transparent, positionné biaxialement, basé par exemple sur un polyéthylènetérephtalate. Le film adhésif est un adhésif acrylique contenant des inhibiteurs d'UV capables de protéger le produit pendant toute sa durée de vie. La transmission de la luiière par ce film n'est pas inférieure à 85% et la transmission des UV n'est pas supérieure à 5X.  Instead of this plastic layer, one can use a self-adhesive film made of polyester, optically transparent, positioned biaxially, based for example on a polyethylene terephthalate. The adhesive film is an acrylic adhesive containing UV inhibitors capable of protecting the product during its entire lifetime. The transmission of the bed by this film is not less than 85% and the transmission of UV is not more than 5X.

Le complexe est assemblé au moyen de techniques de stratification connues et est ensuite scellé le long du bord avec un agent de scellement en polyuréthane. The complex is assembled using known lamination techniques and is then sealed along the edge with a polyurethane sealant.

Le test de résistance consiste à soumettre le complexe à des coups répétés,,de 25 Joules chacun , avec une bâton dont la pointe présente les dimensions suivantes: longueur totale de la pointe 45 un, grand diamètre 40 mm, diamètre de la pointe en forme de bille 4 mm.  The resistance test consists in subjecting the complex to repeated strokes, of 25 Joules each, with a stick whose tip has the following dimensions: total length of the tip 45 un, large diameter 40 mm, diameter of the shaped tip 4 mm ball.

Le test est valable si après 25 coups de 25 Joules chacun on n a pas créé une ouverture permettant la pénétration de l'ensemble de la pointe du marteau. The test is valid if after 25 strokes of 25 Joules each one has not created an opening allowing the penetration of the whole of the point of the hammer.

Des caractéristiques et avantages additionnels de la présente inventionseront mieux compris a' à laide de 1 'exemple de réalisation suivant de l'invention présenté seulement à titre d'exemple non limitatif. Additional features and advantages of the present invention will be better understood with the aid of the following embodiment of the invention presented only by way of nonlimiting example.

Deux feuilles de verre flotté d'une composition du type silicesodium-calcaire et d'une épaisseur de 2,6 mm sont chacune ployées dans un four de flexion, puis assemblées avec une feuille de polycarbonate
