Abstract

Protective glazing is laminated using at least 2 sheets of glass with adhesive bonding to at least 1 sheet of strong plastic material, specifically polyester. Lighter than panels of equivalent strength of toughened glass bonded by butyral film, e.g. may be about 7 mm thick overall instead of 20-30, hence simpler to install - more resistant to repetitive blows from e.g. an axe. Polyester layers may be printed, tinted or (metallic) coated to modify the appearance, exclude UV light etc. Pref. the face of the laminate closest to protected personnel in e.g. a pay booth etc. is lined with an additional sheet of plastics material, pref. of polyester or polycarbonate. The interfaces of the glass and plastics sheet layers may be bonded using polyvinylbutyral film.

Description

La présente invention est relative à des perfectionnements aux vitrages de sécurité. The present invention relates to improvements in safety glazing.

On connaît des vitrages de sécurité, qui sont constitués par l t association de plaques de verre collées à l'aide d'un film plastique tel que du butyral. Safety glazing is known, which is constituted by the combination of glass plates bonded using a plastic film such as butyral.

Le butyral est un adhésif, sans résistance mécanique, qui a uniquement pour fonction de coller le verre. Butyral is an adhesive, without mechanical resistance, which only has the function of bonding the glass.

Ces vitrages de sécurité sont obtenus par un laminage à chaud a l'aide d'une presse à rouleaux puis subissent un traitement thermique sous pression, la température atteinte étant de 1000 à 1350 C pour une pression variant de six à douze Bars. These safety glazings are obtained by hot rolling using a roller press and then undergo a heat treatment under pressure, the temperature reached being from 1000 to 1350 C for a pressure varying from six to twelve Bars.

Ces vitrages nécessairement épais ( 20 a' 30 millimètres) sont très lourds et nécessitent des encadrements spéciaux pour les recevoir. De ce fait, ils ne peuvent pas être adaptés aux fenêtres et portes existantes. These necessarily thick glazing (20 to 30 millimeters) are very heavy and require special frames to receive them. Therefore, they cannot be adapted to existing windows and doors.

Par ailleurs, malgré leur épaisseur, ces vitrages ne résistent guère à des coups répétés ( coups de masse, hache ou pioche). In addition, despite their thickness, these glazings do not withstand repeated blows (blows, axes or picks).

La présente invention qui remédie à ces inconvénient s est relative à un vitrage feuilleté constitué dans sa forme la plus simple par deux plaques de verre entre lesquelles est intercalée une feuille de matière plastique mécaniquement résistance telle qu'unie feuille de polyester. The present invention which overcomes these drawbacks relates to laminated glazing constituted in its simplest form by two glass plates between which is inserted a sheet of mechanically resistant plastic material such as a polyester sheet.

On peut réaliser ainsi un vitrage de sécurité dont 1 t épaisseur est d'environ 7millimètres. It is thus possible to produce a safety glazing whose thickness 1 t is approximately 7 millimeters.

L' invention sera mieux comprise par la description qui va suivre faite en se référant au dessin annexé sur lequel
La figure 1 est une vue en perspective d'un vitrage conforme à l'invention;
La figure 2 est une vue en coupe montrant une variante de réalisation.The invention will be better understood from the description which follows, made with reference to the appended drawing in which
Figure 1 is a perspective view of a glazing according to the invention;
Figure 2 is a sectional view showing an alternative embodiment.

En se reportant à la figure 1, on voit que ce vitrage est constitué dans sa forme la plus simple par deux plaques de verre 1 entre lesquelles est disposée une feuille de matière plastique 2 ayant une bonne résis tance mécanique telle qu'une feuille de polyester.les deux plaques de verre et la fouille plastique sont oollées à l'aide de deux films adhésifs 3, en butyral par exemple. Referring to Figure 1, we see that this glazing is constituted in its simplest form by two glass plates 1 between which is disposed a plastic sheet 2 having good mechanical strength such as a polyester sheet .the two glass plates and the plastic excavation are glued using two adhesive films 3, in butyral for example.

Comme pour les verres feuilletés usuels, ce vitrage est obtenu par un laminage à chaud suivi d'un passage en autoclave à une température comprise entre 800 et 1350C sous une pression de quatre à douze Bars, durant une période de 15 à 60 minutes. As with the usual laminated glasses, this glazing is obtained by hot rolling followed by passage in an autoclave at a temperature between 800 and 1350C under a pressure of four to twelve Bars, during a period of 15 to 60 minutes.

La feuille de polyester peut être teintée,métallisée.  The polyester sheet can be tinted, metallized.

ou recouverte dtune pellicule de métal.or covered with a metal film.

Les métaux ou oxydes métalliques recouvrant le film polyester pourront être choisis en vue de leur aptitude à arrêter les ondes radars,infrarouges, ultraviolettes ou autres. The metals or metal oxides covering the polyester film may be chosen for their ability to stop radar, infrared, ultraviolet or other waves.

Le film polyester pourra être imprimé ou coloré dans le but d'obtenir un vitrage de sécurité présentant des parties transparentes et des parties opaques. The polyester film may be printed or colored in order to obtain a safety glazing having transparent parts and opaque parts.

Naturellement, pour augmenter la résistance du vitrage, il est possible d'utiliser plusieurs feuilles de polyester intercalées chacune entre deux plaques de verre comme montré sur la figure 2. Naturally, to increase the resistance of the glazing, it is possible to use several polyester sheets each interposed between two glass plates as shown in FIG. 2.

Toujours dans le but dtaugmenter la résistance du vitrage, notamment contre les balles, la plaque de verre située vers la personne à protéger,celle la, par exemple, pourra etre recouverte par une feuille de polyester 2as comme montré sur la figure 2. Still with the aim of increasing the resistance of the glazing, in particular against bullets, the glass plate situated towards the person to be protected, that one, for example, may be covered with a sheet of polyester 2as as shown in FIG. 2.

Pour certaines applications, le plaque de verre la recouverte ou non de la feuille 2a pourra être remplacée par une plaque en polycarbonate.  For certain applications, the glass plate, whether covered with the sheet 2a or not, may be replaced by a polycarbonate plate.
