Abstract
Description
La présente invention concerne la décoration de feuils les ou plaques en lésine synthéique et plus particulière- ment ltexécution de motifs graphiques divers sur et à l'in- térieur de ces feuilles ou plaques sur une épalsseur pouv vant être de l'ordre de 1 à 10/10ème de millimètre,
Il est courant de revêtir des feuilles au moyen de motifs graphiques qui sont peints ou collés, zains ces moyens sont peu satisfaisants car les motifs graphiques sont rapidement detériores On a aussi déjà proposé d'utiliser un papier transfert recouvert d'encres sublimables mais des difficultés se présentent pour empêcher l'adhérence du pa- pier transfert ou obtenir une diffusion convenable des en cres sublimables à travers un écran antiadhérent qui le plus souvent altère le dessin pendant l'opération de transfert.The present invention relates to the decoration of sheets or plates in synthetic lesion and more particularly the execution of various graphic patterns on and inside these sheets or plates on a spreader which can be of the order of 1 to 10 / 10th of a millimeter,
It is common to coat sheets with graphic patterns that are painted or glued, zains these means are not very satisfactory because the graphic patterns are quickly deteriorating We have also already proposed using a transfer paper covered with sublimable inks but difficulties are presented to prevent the adhesion of the transfer paper or to obtain a suitable diffusion of sublimable inks through a non-stick screen which most often alters the design during the transfer operation.
La présente invention crée un nouveau procédé et de nouveaux moyens de décoration par transfert qui peuvent être mis en oeuvre avec de très nombreuses résines synthétiques et qui permettent de façon extrêmement bon marché de déco rer des feuilles ou plaques en leur faisant comporter n'im- porte quel motif graphique et, en particulier, tous ceux qui sont mis en oeuvre de façon connue pour des tissus
Compte tenu de la profondeur de pénétration obtenue, les feuilles décorées peuvent être thermoformées fronces et autrement usinées.The present invention creates a new process and new means of decoration by transfer which can be implemented with a very large number of synthetic resins and which make it extremely inexpensive to decorate sheets or plates by making them contain no material. which graphic motif and, in particular, all those used in a known manner for fabrics
Given the depth of penetration obtained, the decorated sheets can be thermoformed gathered and otherwise machined.
Conformément a l'invention, le procédé pour la déco ration d'une feuille ou plaque en résine est caractérisé en ce qu'on forme ou dépose sur ladite plaque un écran actif non adhérent contenant un vecteur de diffusion, en ce qu'on recouvre au moins partiellement l'écran actif par un papier transfert, en ce qu'on dispose le complexe feuille ou pla que de résine, écran actif et feuille de papier transfert dans une presse, en ce qu'on soumet ce complexe à une pression comprise entre 1 et 20 kg/cm 2, en ce qu'on chauffe à une température comprise entre 100 et 22O0C pour laquelle les encres du papier transfert sont sublimées et diffusées, en ce qu'on maintient cette température pendant une durée de 1 à 30 minutes dépendant de la profondeur de pénétration recherchée pour les encres sublimables à l'intérieur de la feuille ou plaque en résine et en ce qu'an procède à un refroidissement avant de séparer le papier transfert de l'écran actif. According to the invention, the method for decorating a sheet or plate of resin is characterized in that an active non-adherent screen containing a diffusion vector is formed or deposited on said plate, in that it covers at least partially the active screen by a transfer paper, in that the resin sheet or plate complex is placed, active screen and transfer paper sheet in a press, in that this complex is subjected to a pressure included between 1 and 20 kg / cm 2, in that it is heated to a temperature between 100 and 220 ° C. for which the inks of the transfer paper are sublimated and diffused, in that this temperature is maintained for a period of 1 to 30 minutes depending on the depth of penetration desired for the sublimable inks inside the resin sheet or plate and in that it performs cooling before separating the transfer paper from the active screen.
Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit. Various other characteristics of the invention will also emerge from the detailed description which follows.
Pour l'exécution du procédé de l'invention, pour la décoration de feuilles ou plaques en résine, on utilise des feuilles de papier, dit transfert,c'est-a'-dire des feuilles de papier ou matière analogue qui ont été imprimées suivant des motifs divers au moyen d'encres sublimables qu'il est inutile de décrire= étant donné qu'elles sont bien connues dans la technique, de méme que sont également bien connus les moyens de préparation desdits papiers de transfert. For the execution of the process of the invention, for the decoration of resin sheets or plates, sheets of paper, called transfer paper, that is to say sheets of paper or similar material which have been printed, are used. according to various patterns by means of sublimable inks which it is useless to describe = since they are well known in the art, just as are also well known the means for preparing said transfer papers.
Les feuilles ou plaques de résine constituant le support sont, par ailleurs, préparées de la façon habituelle à la nature desdites feuilles ou plaques qui sont normalement plastifiées et traitées exactement comme Si elles devaient titre mises en oeuvre sans titre, au préalable, décorées. The resin sheets or plates constituting the support are, moreover, prepared in the usual manner for the nature of said sheets or plates which are normally plasticized and treated exactly as if they were to be used without title, previously decorated.
Des résines qui conviennent bien à la mise en oeuvre du procédé de l'invention sont,par exemple, des dérivés acryliques (polymétacrylate de méthyle coulé et extrudé par exem ple), les polycarbonates, l'acétate de cellulose, etc. Cette énumération n'est pas limitative, d'autres résines pouvant, le cas échéant, ttre utilisées et en particulier toutes les résines présentant un risque de collage avec les papiers transfert du commerce lors du traitement thermique (et surtout celles qui ne présentent pas d'incompatibilité avec les plastifiants de l'acétate de cellulose, exemple phtalate d' éthyle-méthyle, etc.). Resins which are very suitable for carrying out the process of the invention are, for example, acrylic derivatives (polymethyl methacrylate cast and extruded for example), polycarbonates, cellulose acetate, etc. This list is not exhaustive, other resins which can, if necessary, be used and in particular all resins presenting a risk of sticking with commercial transfer papers during heat treatment (and especially those which do not have 'incompatibility with plasticizers of cellulose acetate, example ethyl-methyl phthalate, etc.).
Une opération importante consiste à former ou rapporter un écran actif sur la face ou les parties de la ou des faces des feuilles ou plaques en résine qui doivent être décorées. An important operation consists in forming or attaching an active screen to the face or the parts of the face or faces of the resin sheets or plates which are to be decorated.
L'écran actif : I - ne doit pas adhérer au support gue l'on veut décorer, 2 - doit permettre le passage des colorants à la température
de sublimation 3 - ne doit pas altérer le dessin pendant l'opération de
transfert. The active screen: I - must not adhere to the support that we want to decorate, 2 - must allow the passage of dyes at temperature
sublimation 3 - must not alter the design during the
transfer.
Pour satis.fCire à es conditions on utilise un film d'acétate de cellulose surplastifié (quantité de plastifiant 30 à 55 %) contenant des solvants légers (5 à 10 %) (cétones acétone par exemple - alcools éthanol par exemple)
Les plastifiants sont ceux compatibles avec le diacétate de cellulose (par exemple ; phtalate de méthylegphtalate dwéthyle,triacétine, etc ..)
Le ou les plasfifiants présents jouent le rôle de vecteurs en favorisant la pénétration des colorants dans le support à la température de sublimaSione
L'épaisseur de écran peut être inférieure ou egale à 2/10 de mm.For satis.fCire at es conditions use a film of cellulose acetate overplasticized (amount of plasticizer 30 to 55%) containing light solvents (5 to 10%) (ketones acetone for example - ethanol alcohols for example)
The plasticizers are those compatible with cellulose diacetate (for example; methyl phthalate, dwethyl phthalate, triacetin, etc.)
The plasticizer (s) present play the role of vectors by promoting the penetration of dyes into the support at the sublimaSione temperature.
The screen thickness can be less than or equal to 2/10 mm.
L'écran peut être formé directement sur les feuilles ou plaques à décorer en projectant ou déposant sur cellesci un collodion contenant les constituants mentionnés cidessus. The screen can be formed directly on the sheets or plates to be decorated by projecting or depositing on them a collodion containing the constituents mentioned above.
Le papier de transfert est ensuite mis en place sur l'écran formé et l'ensemble est disposé sous une presse chauffante pour être soumis à une pression comprise entre 1 et 20 kg/cm 2. The transfer paper is then placed on the formed screen and the assembly is placed under a heating press to be subjected to a pressure of between 1 and 20 kg / cm 2.
En même temps que le complexe, feuille ou plaque de résine, écran et papier de transfert, est soumis à la presse sion de la presse, il est porté à une température comprise entre 100 et 2200C pendant une durée de 1 à 30 minutes qui est fonction de la profondeur de pénétration désirée,
Le complexe est ensuite refroidi et la résine décorée séparée de 1ensemble papier-transfert-écran actif
L'invention se prête bien à la décoration de lgacé- tate de cellulose tranché ou extrudé.At the same time as the complex, resin sheet or plate, screen and transfer paper, is subjected to the press of the press, it is brought to a temperature between 100 and 2200C for a period of 1 to 30 minutes which is depending on the desired penetration depth,
The complex is then cooled and the decorated resin separated from the active paper-transfer-screen assembly
The invention lends itself well to the decoration of sliced or extruded cellulose acetate.
écran actif utilisé dans ce cas peut être un polyester type terphane ne contenant pas à l'origine les adjuvants actifs cités précedemment (acétone, éthanol d'une part et phtalate de méthyleou d'éthyleou triacétine d'autre part)
Cet écran assure cependant les mêmes fonctions qu'un film d'acétate surplastifié. En effet, dans ce cas, les plastifiants et solvants contenus dans le support migrent dans l'écran de polyester qui assure donc à cet instant les fonctions et le rôle décrits pour le film actif d'acétate de cellulose surplastifié. Des profondeurs de pénétration de 10/10 de mm furent obtenues ainsi que pour les polycarbo- nates tandis que pour les polymétacrylates de méthyle des profondeurs de pénétration de 1,5 à 5/10 de mr sont obtenues.active screen used in this case can be a terphane type polyester which does not originally contain the active additives mentioned above (acetone, ethanol on the one hand and methyl or ethyl phthalate or triacetin on the other hand)
However, this screen performs the same functions as an overplasticized acetate film. Indeed, in this case, the plasticizers and solvents contained in the support migrate into the polyester screen which therefore ensures at this instant the functions and the role described for the active film of overplasticized cellulose acetate. Penetration depths of 10/10 mm were obtained as well as for the polycarbonates while for polymethyl methacrylates penetration depths of 1.5 to 5/10 of mr were obtained.
Les feuilles ou plaques décorées peuvent ensuite éventuellement être mises en forme par les procédés habituels à la technique des résines qui les constituent. The decorated sheets or plates can then optionally be shaped by the usual methods in the technique of the resins which constitute them.
L'invention n'est pas limitée à l'exemple de réalisation décrit en détail, car diverses modifications peuvent y être apportées sans sortir de son cadre. The invention is not limited to the embodiment described in detail, since various modifications can be made thereto without departing from its scope.
