Abstract
Description
DESCRIPTION
La présente invention se réfère aux vitrages, glaces,
panneaux de verre et produits qui en découlent composée de
teuilles superposées de verre soudé à chaud entre elles, au
moyen de feuilles intercalaires de matière thermoplastique.DESCRIPTION
The present invention relates to glazing, glass,
glass panels and resulting products consisting of
overlapping sheets of glass welded together,
by means of interlayer sheets of thermoplastic material.
Il est utilisé couramment dans l'industrie verrière principalement : 2 sortes de méthodes pour donner au verre l'aspect coloré
1. le verre coloré dans la masse
2. dans le cas des fabrications de verre feuilleté, la
teinte dans la masse du butyral de polyvinil lui même.It is commonly used in the glass industry mainly: 2 kinds of methods to give the glass the colored appearance
1. the mass colored glass
2. in the case of laminated glass manufacturing, the
mass tint of polyvinil butyral itself.
En ce qui concerne le verre teint dans la masse par l'ap- port d'oxydes metalliques, les quelques grandes manufactures verrieres qui se seont lancées dans ces fabrications pouvaient proposer à leurs clients des gammes de tons intéressantes mais elles ont dci limiter et même stopper ce type de production, les techniques de coulées sur table s'étant avérées, à la longue, d'un coût de revient trop élevé. With regard to glass dyed in the mass by the supply of metal oxides, the few large glass manufacturers who have embarked on these productions could offer their customers interesting ranges of tones but they had to limit and even stop this type of production, the techniques of table casting having proven, in the long run, to cost too high.
Dans le cas des fabrications de verre feuilleté, la teinte colorée des verres est obtenue en utilisant des butyles préalablement teintés dans la masse - mais la gamme de tons est limitée à quelques teintes classiques : bronze, sepia, gris, en tout. In the case of laminated glass manufacturing, the colored tint of the glasses is obtained using butyls previously tinted in the mass - but the range of tones is limited to a few conventional tints: bronze, sepia, gray, in all.
La présente invention a pour but l'obtention de volumes de verre feuilleté, toutes dimensions, colorés sans aucune limite de teintes et dont l'aspect final s'apparente aux volumes de verre teintés dans la masse. The object of the present invention is to obtain volumes of laminated glass, all dimensions, colored without any shade limit and whose final appearance is similar to volumes of glass tinted in the mass.
En effet le film coloré teint, caracteristique importante de l'svention, peut être lié à des matières thermocollables tel le butyral de polyvinil utilisés couramment dans les techniques de laminage.
Aussi, 11 ensemble stratifié ou "sandwich" est formé au pré- alable. Il se décompose donc d'une plaque de verre (I) d'une feuille de plastique thermocollable (2) d'un film gélatiné coloré teinté dans la masse (3) spécifique de l'invention, d'une feuille de plastique thermocollable ou butyral de polyvinil (4) et d'une autre plaque de verre qui achève la structure (5).Indeed the dyed colored film, an important characteristic of the invention, can be linked to heat-sealable materials such as polyvinyl butyral commonly used in lamination techniques.
Also, the laminate or "sandwich" assembly is formed beforehand. It therefore breaks down of a glass plate (I) of a sheet of heat-sealable plastic (2) of a colored gelatin film tinted in the mass (3) specific to the invention, of a sheet of heat-sealable plastic or polyvinil butyral (4) and another glass plate which completes the structure (5).
L'ensemble stratifié ou "sandwich" préalablement chauffé à environ 80 , est calendré dans une presse à rouleau permettant d'évacuer la totalité de l'air inclus entre les deux feuilles de matière plastique et le film gélatiné. The laminate or "sandwich" assembly, previously heated to around 80, is calendared in a roller press allowing all the air included between the two plastic sheets and the gelatin film to be removed.
Le vitrage ainsi pré-collé est ensuite introduit dans un autoclave relié à une source d'air sous pression et équipé de ri- sistances électriques - la température et la pression de l'air sont graduellement portées à environ 1200 à 1400 et à 12Kg/m2. The glazing thus pre-bonded is then introduced into an autoclave connected to a source of pressurized air and equipped with electrical resistances - the temperature and the pressure of the air are gradually brought to approximately 1200 to 1400 and to 12 kg / m2.
Une des caractéristiques essentielles de l'invention est d'utiliser principalement les propriétés et les affinités qu'ont les colorants substantifs directs diazols à teindre la gélatine de nos films décrits dans l'invention. One of the essential characteristics of the invention is to use mainly the properties and the affinities that the diazol direct substantive dyes have for dyeing the gelatin of our films described in the invention.
Or, il est connu depuis longtemps que dans le comportement d'un colorant soluble vis à vis de la gélatine, il faut distinguer deux cas
1. La gélatine n'est pas tannée
2. La gélatine est tannéé ( cas d'une image photogra
phique ) l'action des colorants se répartit de la
manière suivante
a) Le colorant ne teint, d'une façon permanente, que la
gélatine non tannée
b) Le colorant teint, d'une façon permanente, que la gé
latine tannée
c) Le colorant ne teint pas la gélatine d'une façon per
manente - par simple lavage, il diffuse rapidement
dans l'eau.However, it has long been known that in the behavior of a soluble dye with respect to gelatin, two cases must be distinguished.
1. The gelatin is not tanned
2. The gelatin is tanned (case of a photogra image
the action of the dyes is distributed from the
next way
a) The dye dyes, only permanently, the
untanned gelatin
b) The dye dyes, permanently, that the ge
tanned latin
c) The dye does not dye the gelatin in a per
manente - by simple washing, it diffuses quickly
in water.
I1 est à observer qu'il n'y a pas de colorants susceptibles de se fixer exclusivement sur la gélatine tannée - il devient alors nécessaire d'incorporer un mordant - on tombe alors dans la technique de la teinture après mordançage dans laquelle un colorant basique ne teinte pas la gélatine en milieu acide, mais se fixe sur le mordant B.7735904. It should be noted that there are no dyes capable of being fixed exclusively on the tanned gelatin - it then becomes necessary to incorporate a mordant - we then fall into the technique of dyeing after etching in which a basic dye does not tint gelatin in an acid medium, but fixes on the mordant B.7735904.
L'on a choisit donc pour un rendement optimum de la qualiv té des films colorés gélatinés teintés et de leur tenue à la lumière et à la chaleur, la technique courante des teintures sur coton ou viscose en utilisant les colorants pour gélatine non tannée appartenant notamment à la classe des colorants substantifs type diazoi lumière directs. We therefore chose for optimum performance the quality of tinted gelatin colored films and their resistance to light and heat, the common technique of dyeing on cotton or viscose using non-tanned gelatin dyes belonging in particular to the class of diazoi type direct light dyes.
En effet le film teinté spécifique à l'invention doit avoir un grand nombre de propriétés qui se trouvent réunies dans l'invention à savoir
1. Stabilité dimensionnelle parfaite avec une faible éläs-
ticité dans le sens de la machine
2. Transparence optique la meilleure, c'est à dire un
film gélatiné teinté exempt de voiles colorées non dé
spirées ou taches et manque d'unisson
3. Possibilité d'être chauffé une fois teinté et traité
au moins jusqu'a 1300 pour le feuilletage des verres
( stratification - calendrage ) sans altération de la
couleur et résultat final
4. Résistance à la rupture et à-la déchirure du film soumis
à des pressions variables de l'ordre de 12 Kg/cm2 ou
plus
5.Adhérence optimum à des matériaux thermoplastiques et
en particulier au butyral de polyvinil
6. Stabilité parfaite des couleurs transparentes obtenues
grâce aux colorants utilisés dans l'invention. In fact, the tinted film specific to the invention must have a large number of properties which are found in the invention, namely
1. Perfect dimensional stability with low eläs-
machine direction
2. The best optical transparency, ie a
tinted gelatin film free of undyed colored veils
spirea or spots and lack of unison
3. Possibility of being heated once tinted and treated
at least up to 1300 for laminating glasses
(stratification - calendaring) without altering the
color and end result
4. Tear resistance and tear resistance of the film submitted
at variable pressures of the order of 12 Kg / cm2 or
more
5. Optimal adhesion to thermoplastic materials and
especially at polyvinil butyral
6. Perfect stability of the transparent colors obtained
thanks to the dyes used in the invention.
Pour obtenir l'unisson maximum des films teintés
et donner au verre fabriqué -la teinte la plus uniforme possible la technique d'immersion des films est la meilleure et nous la presentons comme une des caracteristiques essentielles suplementaire à l'invention - En effet une des grandes difficultés de teinture des films gélatinés, consiste bien evidemment à éviter les voiles ou taches.To obtain the maximum unison of tinted films
and give the glass produced - the most uniform tint possible the film immersion technique is the best and we present it as one of the essential characteristics additional to the invention - Indeed one of the great difficulties of dyeing gelatin films, consists Obviously to avoid veils or stains.
Aussi l'immersion des films en partant de rouleaux et plongeant dans les bains de couleurs,permet d'obtenir les meilleurs unissons des fims gélatinés. Also the immersion of the films starting from rolls and plunging into the color baths, allows to obtain the best unison of gelatin films.
Ces volumes de verre feuilletés colorés ainsi labri qués resolvent les problèmes du particulier - des decorateurs des architectes d'intérieur ou des professionels du verre lorsqu ils se heurtent à la demande : TRANSPARENCE - COLORIS
SANS LIMITE - VERRE ET SECURITE
Suivant l'invention il peut etre realisé dans le domaine de l'architecture : cloisons - garde corps - plafonds lumineux - portes murs transparents - paravents - tables etc.These volumes of colored laminated glass thus labeled solve the problems of the individual - decorators, interior designers or glass professionals when they come up against demand: TRANSPARENCY - COLORS
UNLIMITED - GLASS AND SECURITY
According to the invention it can be carried out in the field of architecture: partitions - railings - light ceilings - transparent wall doors - screens - tables etc.
In doit etre bien entendu que les applications de l'invention ne sont limitées au simple verre feuilleté fabriqué avec les verres de 3mm - 4mm - ou des glaces de IOmm ou
IZmm d'epaisseur ; c'est ainsi que l'on peut realiser des vitrages feuilletés comportant plus de deux feuilles de verre associées les unes aux autres par des couches de matières thermoplastique, intercalées de la mème manière par les les films colorés teintés spécifiques à l'invention, ce qui permet d'obtenir des vitrages anti effraction ou pare balle. It should be understood that the applications of the invention are not limited to simple laminated glass made with 3mm - 4mm glasses or 10mm glass or
IZmm thick; this is how laminated glazing can be produced comprising more than two glass sheets associated with each other by layers of thermoplastic material, interleaved in the same way by the tinted colored films specific to the invention, which makes it possible to obtain burglar-proof or bullet-proof glazing.
Egalement le volume de verre fabriqué sous la forme specifique à l'invention , peut-etre réalisé en utilisant une plaque de verre en partie dorsale , préalablement argenté ainsi à sa sortie de l'autoclave, le volume de verre presente le rendu d'un miroir coloré teinté du plus bel effet. Also the volume of glass manufactured in the form specific to the invention, perhaps produced using a glass plate in the dorsal part, previously silvered thus on leaving the autoclave, the volume of glass presents the rendering of a colored mirror tinted with the most beautiful effect.
