Description

La présente invention concerne un procédé continu d'obtention de revêtements plastiques décorés pour sols ou murs et l'installation prévue pour la mise en oeuvre de ce procédé.The present invention relates to a continuous process for obtaining decorated plastic coverings for floors or walls and the installation provided for the implementation of this process.

On sait que les feuilles de polychlorure de vinyle, comportant éventuellement une armature telle qu'un mât de fibres de verre, une grille, etc. destinées à recevoir une impression sont couramment fabriquées par enduction, c'est-à-dire par application, à l'aide d'un matériel classique (racle, reverse-roll coater, machine à rideau, etc.) d'une composition vinylique liquide à base de polychlorure de vinyle additionné de plastifiants et de divers additifs. Cette enduction doit ensuite être solidifiée à chaud, généralement entre 150 et 180 °C, de façon à assurer sa gélification. Cette opération de gélification peut être effectuée dans un four ; elle l'est aussi avantageusement au contact d'un cylindre parfaitement poli chauffé aux températures nécessaires, ce qui permet de réaliser, en même temps que la gélification, un parfait état de surface de la couche plastique obtenue. Ces cylindres ou tambours de gélification sont couramment utilisés dans l'industrie des revêtements de sol ou de mur plastiques, et de l'enduction vinylique en général.It is known that polyvinyl chloride sheets, possibly comprising a frame such as a glass fiber mast, a grid, etc. intended to receive an impression are commonly manufactured by coating, that is to say by application, using a conventional material (doctor blade, reverse-roll coater, curtain machine, etc.) of a vinyl composition polyvinyl chloride liquid supplemented with plasticizers and various additives. This coating must then be solidified hot, generally between 150 and 180 ° C, so as to ensure its gelation. This gelling operation can be carried out in an oven; it is also advantageously in contact with a perfectly polished cylinder heated to the necessary temperatures, which makes it possible to achieve, at the same time as the gelation, a perfect surface condition of the plastic layer obtained. These gelification cylinders or drums are commonly used in the industry of plastic floor or wall coverings, and vinyl coating in general.

Un grand nombre de ces produits plastiques à base de polychlorure de vinyle (PVC) enduits ou calandrés, tels que nappes, stores, rideaux, bâches, revêtements de sols, revêtements de mur, etc. comportent un décor apporté par une impression en plusieurs couleurs. Cette impression peut être réalisée par différentes techniques : héliographie, offset, sérigraphie (à plat ou au cadre rotatif), flexographie, etc. et elle est en général appliquée après gélification du support plastique à décorer.A large number of these coated or calendered polyvinyl chloride (PVC) plastic products, such as tablecloths, blinds, curtains, tarpaulins, floor coverings, wall coverings, etc. have a decor provided by printing in several colors. This printing can be done by different techniques: heliography, offset, screen printing (flat or rotary frame), flexography, etc. and it is generally applied after gelation of the plastic support to be decorated.

L'impression directe sur un support plastique non gélifié peut en effet poser un certain nombre de problèmes en raison, notamment, de l'instabilité dimensionnelle dudit support entraînant des déformations du dessin.Direct printing on a non-gelled plastic support can indeed pose a certain number of problems due, in particular, to the dimensional instability of said support resulting in deformations of the design.

Il est bien entendu possible d'intégrer, à la-suite du dispositif de gélification du support plastique, une unité d'impression, afin de fabriquer de façon continue les revêtements décorés. Toutefois, et en raison non seulement de l'investissement élevé que présente une machine à imprimer mais aussi du coût important de gravure ou préparation des cadres ou matrices nécessaires à l'obtention de chaque couleur du dessin à réaliser, cette intégration ne se justifie économiquement que pour l'obtention de métrages importants pour un même dessin.It is of course possible to integrate, following the gelling device of the plastic support, a printing unit, in order to continuously manufacture the decorated coatings. However, and due not only to the high investment presented by a printing machine but also to the significant cost of engraving or preparing the frames or dies necessary to obtain each color of the design to be produced, this integration is not justified economically. than for obtaining important footage for the same drawing.

Il faut enfin noter que l'utilisation d'unités d'impression classiques pour l'échantillonnage des dessins, que ces unités soient ou non intégrées dans une ligne continue de fabrication, aggrave le prix de revient de l'impression, en raison notamment du coût élevé de certains supports plastiques.Finally, it should be noted that the use of conventional printing units for sampling designs, whether or not these units are integrated into a continuous production line, increases the cost of printing, in particular because of the high cost of certain plastic supports.

On s'est vite rendu compte de tout l'intérêt présenté par le procédé d'impression par transfert selon lequel le dessin à réaliser est tout d'abord imprimé sur un papier de faible coût avant d'être transféré, comme par décalcomanie, sur le support plastique.We quickly realized all the interest presented by the transfer printing process according to which the drawing to be produced is firstly printed on a low cost paper before being transferred, as by decal, on the plastic support.

Le papier utilisé dans ce but est traité, avant impression, à l'aide de compositions spécialement mises au point pour que les encres normalement utilisées pour l'impression du chlorure de polyvinyle (généralement à base de copolymères d'acétate et de chlorure de polyvinyle) n'y adhèrent que faiblement et puissent être totalement transférées à chaud sur le support plastique à décorer.The paper used for this purpose is treated, before printing, using compositions specially developed so that the inks normally used for printing polyvinyl chloride (generally based on copolymers of acetate and polyvinyl chloride ) adhere to it only weakly and can be completely transferred hot on the plastic support to be decorated.

L'opération même de transfert se fait habituellement à une température comprise entre 100° et 180 °C et sous une faible pression, la face imprimée du papier et la face à décorer du support plastique sont maintenues en contact pendant un temps très court mais toutefois suffisant pour réaliser le transfert de l'impression du papier au support plastique.The actual transfer operation is usually done at a temperature between 100 ° and 180 ° C and under low pressure, the printed side of the paper and the side to be decorated with the plastic support are kept in contact for a very short time, but however sufficient to transfer the printing from paper to plastic support.

Cette opération se fait sur tout équipement permettant d'assurer un contact intime aux températures nécessaires entre le papier imprimé et le support plastique, par exemple sur des glaceuses, des doubleuses, ou des machines de doublage utilisées dans l'industrie des plastiques et du caoutchouc, telles que celles désignées commercialement sous les marques de : Auma, Rotodorn, Rotocure, etc. La vitesse à laquelle s'effectue le transfert est relativement élevée et se situe entre 20 et 50 m/min. Après un refroidissement modéré (jusqu'à 50-80 °C par exempte) te papier est séparé du support plastique sur lequel a été transféré le dessin imprimé.This operation is carried out on any equipment ensuring intimate contact at the necessary temperatures between the printed paper and the plastic support, for example on glazing machines, doublers, or doubling machines used in the plastics and rubber industry. , such as those designated commercially under the brands of: Auma, Rotodorn, Rotocure, etc. The speed at which the transfer takes place is relatively high and is between 20 and 50 m / min. After moderate cooling (up to 50-80 ° C for example) the paper is separated from the plastic support onto which the printed design has been transferred.

La présente invention s'est donné pour but de proposer un procédé continu d'obtention de revêtements plastiques décorés qui soit applicable, dans des conditions économiques, à de faibles métrages et ne nécessite pas d'investissements importants.The object of the present invention is to propose a continuous process for obtaining decorated plastic coatings which is applicable, under economic conditions, to low films and does not require significant investment.

C'est ainsi qu'elle a pour objet un procédé continu d'obtention de revêtements plastiques décorés, notamment pour sols et murs, et dont l'originalité consiste en ce que l'étape d'enduction, à l'aide de plastisol liquide, du support servant d'armature aux dits revêtements est immédiatement suivie d'une étape d'impression par transfert au cours de laquelle la face imprimée du papier transfert est mise au contact de la couche de plastisol liquide et en ce que l'ensemble ainsi constitué est soumis à l'action simultanée de la chaleur et de la pression afin d'assurer en une seule opération le transfert du dessin et la prégélification du plastisol.Thus it has for its object a continuous process for obtaining decorated plastic coatings, in particular for floors and walls, and whose originality consists in that the coating step, using liquid plastisol , the support serving as a framework for said coatings is immediately followed by a transfer printing step during which the printed face of the transfer paper is brought into contact with the layer of liquid plastisol and in that the assembly thus constituted is subjected to the simultaneous action of heat and pressure in order to ensure in a single operation the transfer of the design and the pre-gelation of the plastisol.

Le papier servant à réaliser l'impression transfert est avantageusement muni, avant sa propre impression, d'une couche filmogène à base de produits aptes à faciliter le transfert ultérieur de ladite impression.The paper used to carry out the transfer printing is advantageously provided, before its own printing, with a film-forming layer based on products capable of facilitating the subsequent transfer of said printing.

Parmi les produits convenant à cet usage, on peut citer la zéine, les carboxyméthylcelluloses, les silicones et les résines synthétiques telles que les polyéthylène, le polypropylène et le polyamide.Among the products suitable for this use, mention may be made of zein, carboxymethylcelluloses, silicones and synthetic resins such as polyethylene, polypropylene and polyamide.

Selon un mode de réalisation préféré de l'invention, le support servant d'armature au revêtement de sol ou de mur décoré est constitué par un voile de fibres telles que des fibres de verre, préalablement imprégné d'une couche de plastisol puis gélifié. On dispose ainsi d'une surface parfaitement plane permettant d'obtenir, une fois réalisée l'opération simultanée de gélification et d'impression transfert de ce support enduit d'une nouvelle couche de plastisol liquide, un revêtement ne présentant aucune irrégularité d'aspect.According to a preferred embodiment of the invention, the support serving as a reinforcement for the decorated floor or wall covering consists of a veil of fibers such as glass fibers, previously impregnated with a layer of plastisol and then gelled. There is thus a perfectly flat surface making it possible to obtain, once the simultaneous gelling and transfer printing operation of this support coated with a new layer of liquid plastisol has been carried out, a coating having no appearance irregularity. .

Cette enduction peut être indifféremment appliquée à la racle, comme représenté au dessin, ou à l'aide du dispositif dit « reverse roll ".This coating can be applied to the doctor blade, as shown in the drawing, or using the so-called "reverse roll " device .

Le support (1) enduit avec ce plastisol liquide (2) est ensuite amené au contact du cylindre gélificateur (11) en même temps que le papier transfert imprimé (3) provenant du rouleau (10), la face imprimée du papier (3) étant contre la face enduite du support (1).The support (1) coated with this liquid plastisol (2) is then brought into contact with the cylinder gelling agent (11) at the same time as the printed transfer paper (3) coming from the roll (10), the printed side of the paper (3) being against the coated side of the support (1).

Ce papier transfert (3) est un papier couché de 50 g, préalablement enduit d'une couche dite « release de 20 g/m2 d'une résine telle que le polypropylène ; il a été imprimé en hélio avec une encre présentant la composition suivante :

  • - Copolymère acétate et chlorure de polyvinyle type VYNS, marque déposée, commercialisé par UNION CARBIDE 17 g
  • - Méthyléthyl-cétone 80 g

  • - Methyl ethyl ketone 80 g
  • - Methyl isobutyl ketone 20 g
  • - Microlith K type pigments (registered trademark), marketed by CIBA GEIGY, depending on the color 0.1 to 10 g

La viscosité était ajustée à la méthyl-éthyl-cétone pour obtenir, à l'utilisation, une encre de 30 mPa - s (15 secondes (coupe FORD numéro 4).The viscosity was adjusted with methyl ethyl ketone to obtain, when in use, an ink of 30 mPa - s (15 seconds (FORD cut number 4).

Certaines encres contiennent un inhibiteur d'expansion permettant l'obtention de dessins en relief, tel que l'anhydride trimellitique ou le benzotriazole à une dose allant de 2,5 à 10 %, selon le relief du dessin.Certain inks contain an expansion inhibitor making it possible to obtain relief drawings, such as trimellitic anhydride or benzotriazole at a dose ranging from 2.5 to 10%, depending on the relief of the drawing.

Le cylindre gélificateur (11) est porté à une température qui peut se situer entre 130 et 190 °C et qui, dans le cas d'une ligne marchant à 20 m/minute, se situe aux environs de 170 °C. Le papier transfert imprimé (3) et le voile de verre imprégné (1) et enduit le plastisol gonflable (2) sont pressés ensemble contre le cylindre chaud (1) et restent en contact intime sur une grande partie de la circonférence de ce dernier. A la sortie du cylindre (11) on refroidit le complexe (2-3), puis on sépare le papier qui ne porte plus d'impression et est repris sur le rouleau (12). On peut éventuellement le réimprimer à nouveau pour une opération suivante. L'impression appliquée sur le papier s'est alors transférée sur la couche de plastisol gonflable (2) appliquée au support (1) et l'on obtient un revêtement enduit et imprimé (4).The gel cylinder (11) is brought to a temperature which can be between 130 and 190 ° C and which, in the case of a line running at 20 m / minute, is around 170 ° C. The printed transfer paper (3) and the impregnated glass veil (1) and coated with the inflatable plastisol (2) are pressed together against the hot cylinder (1) and remain in intimate contact over a large part of the circumference of the latter. At the outlet of the cylinder (11) the complex is cooled (2-3), then the paper which is no longer printed is separated and is taken up on the roller (12). You can optionally reprint it again for a subsequent operation. The impression applied to the paper is then transferred to the layer of inflatable plastisol (2) applied to the support (1) and a coated and printed coating (4) is obtained.

On peut ensuite, et spécialement dans le cas où l'encre d'impression contenait un inhibiteur d'expansion, enduire le revêtement imprimé (4), par exemple au moyen d'une installation dite « reverse-roll (non représentée au dessin mais située avant le rouleau de stockage (13)) de 320 g/m2 d'une couche de surface transparente désaérée présentant la composition suivante :

  • - Ba-Zn liquid stabilizer 3 g
  • - 0.2 g ultra-violet absorber
  • - 0.2 g deaeration additive
  • - Dodecyl benzene 5 g

Le support (4) ainsi enduit passe alors dans un four à 200-210 °C. A cette température l'agent gonflant se décompose pour donner une mousse chimique, sauf aux endroits où l'encre d'impression contenait de l'inhibiteur.The support (4) thus coated then passes into an oven at 200-210 ° C. At this temperature the blowing agent decomposes to give a chemical foam, except where the printing ink contained the inhibitor.

La surface est gélifiée.The surface is gelled.

Le revêtement de sol obtenu imprimé et en relief peut, dans certains cas, recevoir à l'envers une enduction supplémentaire de mousse mécanique présentant la composition suivante :

  • - Calcium carbonate 20 g
  • - 3 g silicone surfactant

Ce plastisol est moussé mécaniquement par incorporation d'air sec dans un batteur mécanique du type MONDOMIX (marque déposée). On dépose à la racle 300 g/m2 de mousse mécanique de densité fraîche 500 g au litre. On gélifie dans un four à 175 °C. Le revêtement gélifié et décoré (4) est enroulé en (13).This plastisol is mechanically foamed by incorporating dry air into a mechanical beater of the MONDOMIX type (registered trademark). 300 g / m 2 of mechanical foam with a fresh density of 500 g per liter are applied using a doctor blade. It is gelled in an oven at 175 ° C. The gelled and decorated coating (4) is rolled up at (13).
