Description

La présente invention concerne un procédé amélioré de production d'un produit composite comportant une couche ou strate en un matériau peu poreux tel que l'amiante et destiné à servir de produit de revêtement de sol, L'invention s'étend au produit obtenu par un tel procédé,The present invention relates to an improved process for the production of a composite product comprising a layer or stratum made of a low-porous material such as asbestos and intended to serve as a floor covering product, The invention extends to the product obtained by such a process,

L'invention vise particulièrement à améliorer les propriétés d'adhésivité et de résistance au délaminage d'une feuille d'une matière peu poreuse, en particulier d'amiante intercalée dans l'épaisseur d'un produit de revêtement de sol.The invention is particularly aimed at improving the adhesiveness and delamination resistance properties of a sheet of a slightly porous material, in particular asbestos interposed in the thickness of a floor covering product.

Il existe sur le marché du revêtement de sol un certains nombre de produits incluant une strate généralement en amiante servant de support aux diverses enductions de plastisol PVC et d'impressions d'encre qui vont permettre d'obtenir un produit finit Lorsque cette strate se trouve en sandwich entre deux feuilles: de PVC plastifié, on remarque que l'adhésivité est mauvaise dans la zone de contact et qu'il est possible de délaminer complètement le produit moyennant un travail faible. Des essais ont montré qu'il suffit d'une force de 0,08 kg (1,73,10-3 W) par cm de largeur d'éprouvette pour obtenir cet effet,There are a number of products on the floor covering market, including a layer of asbestos generally used as a support for various coatings of PVC plastisol and ink prints which will allow a finished product to be obtained. sandwiched between two sheets: of plasticized PVC, we notice that the adhesiveness is poor in the contact area and that it is possible to completely delaminate the product with little work. Tests have shown that a force of 0.08 kg (1.73.10 -3 W) per cm of specimen width is sufficient to achieve this effect,

L'expérience indique qu'il faut au moins des valeurs d'adhésivité dix fois supérieures (de l'ordre de 1 kg/cm) pour assurer une Bonne tenue du matériau dans sa manipulation, en particulier lors de la pose et dans le temps, lors de son utilisation en service,Experience has shown that at least ten times higher adhesion values (of the order of 1 kg / cm) are necessary to ensure good resistance of the material in its handling, in particular during installation and over time. , during its use in service,

La présente invention vise donc à améliorer les procédés de production des produits du type indiqué pour en accroître les propriétés,The present invention therefore aims to improve the processes for producing products of the indicated type in order to increase their properties,

Le but ainsi visé est atteint par un procédé comportant au moins les étapes opératoires suivantes :

  • perforation d'un support;
  • enduction d'un plastisol (precoat) compact sur au moins une face du support perforé et
  • + élaboration du produit de manière en soi connue par enductions diverses et décor, comportant au moins une étape de géléfication ou de prégélification. Cette élaboration peut notamment consister en :
  • - prégélification à une température compatible avec la nature du plastique appliqué;
  • - application d'une enduction moussable sur une face du support ayant reçu l'enduction du plastique;
  • - expansion de l'enduction moussable.
The aim thus achieved is achieved by a process comprising at least the following operating steps:
  • perforation of a support;
  • coating of a compact plastisol (precoat) on at least one face of the perforated support and
  • + product development in a manner known per se various coatings and decor, comprising at least one step of gelling or pregelling. This development can notably consist of:
  • - pre-gelation at a temperature compatible with the nature of the plastic applied;
  • - Application of a foamable coating on one face of the support having received the coating of the plastic;
  • - expansion of the foam coating.

Le procédé de l'invention s'applique à de nombreux types de support, qui par suite de leur caractère peu poreux ne permettent pas un bon accrochage chimique et physique des couches d'enduction. On réalise de cette manière une sorte de rivetage à travers le support poreux qui solidarise celui-ci aux couches ultérieures.The method of the invention is applicable to many types of support, which owing to their not very porous nature do not allow good chemical and physical attachment of the coating layers. In this way a kind of riveting is made through the porous support which secures the latter to the subsequent layers.

A titre d'exemple, en plus de l'amiante on peut citer comme support les substituts de l'amiante (Rockwool),les feuilles de papier, de carton et autres matériaux cellulosiques ou les feutres de fibres synthétiques à base de polyoléfines ainsi que des feuilles métalliques (cuivre, aluminium), ces derniers matériaux ayant l'avantage d'apporter des propriétés intéressantes sur le plan thermique.By way of example, in addition to asbestos, there may be mentioned as support the asbestos substitutes (Rockwool), sheets of paper, cardboard and other cellulosic materials or synthetic fiber felts based on polyolefins as well as metallic sheets (copper, aluminum), the latter materials having the advantage of providing advantageous thermal properties.

Le nombre, le diamètre et la dimension de la maille unitaire des perforations réalisées dans le support peuvent être déterminés aisément par le praticien sur base d'essais préalables, en fonction de la nature êt de l'épaisseur du support. On peut recommander des perforations de 0,5 à 3 mm de diamètre disposées selon une maille unitaire de 2 à 20 mm de côté. Ces perforations peuvent être réalisées par tous moyens mécaniques, par exemple à l'aide de matrices et poinçons, à l'aide de cylindres à picots, etc.The number, diameter and dimension of the unit mesh of the perforations made in the support can be easily determined by the practitioner on the basis of preliminary tests, depending on the nature and the thickness of the support. We can recommend perforations of 0.5 to 3 mm in diameter arranged in a unit mesh of 2 to 20 mm side. These perforations can be made by any mechanical means, for example using dies and punches, using spiked cylinders, etc.

A titre d'illustration de bons résultats qui ont pu être obtenus pour l'amiante d'une épaisseur de 0,6 mm, avec des perforations de 1,5 mm de diamètre à partir d'une disposition selon une maille unitaire de 8 mm de côté on peut indiquer que l'on obtient des valeurs d'adhérence de 1,1 kg/cm. Pour une maille de 4 mm de côté, des valeurs de l'ordre de 2,6 kg/cm sont facilement atteintes, ce qui dépasse largement les valeurs de 1 kg/cm considérées comme nécessaires.By way of illustration of good results which have been obtained for asbestos with a thickness of 0.6 mm, with perforations of 1.5 mm in diameter from a disposition according to a unitary mesh of 8 mm side can be indicated which are obtained adhesion values of 1, 1 kg / cm. For a mesh with a side of 4 mm, values of the order of 2.6 kg / cm are easily reached, which greatly exceeds the values of 1 kg / cm considered to be necessary.

Selon une forme préférée de l'exécution de l'invention, l'enduction du plasisol compact se réalise sur les deux faces (recto et verso) du support pexfoxé, cette enduction pouvant se réaliser successivement sur chaque face ou simultanément sur les deux faces,According to a preferred embodiment of the invention, the p lasisol compact is coated on both sides (front and back) of the pexfox support, this coating can be carried out successively on each side or simultaneously on both sides,

Généralement, le plastisol est appliqué pour les épaisseurs les plus courantes du support, sous une épaisseur de 0,005 à 3 mm et de préférence de l'ordre de 0,15 mm, ceci sur les deux faces du support, avec bouchage des trous de manière pratiquement homogène,Generally, the plastisol is applied for the most common thicknesses of the support, under a thickness of 0.005 to 3 mm and preferably of the order of 0.15 mm, this on the two faces of the support, with plugging of the holes so practically homogeneous,

Les techniques d'application du plastisol compact sont bien connues et l'on peut recourir pour cette application notamment à. des racles, à une technique de lame d'air ou encore à la technique connue sous le nom de "reverse roll".The techniques of application of the compact plastisol are well known and one can resort for this application in particular to. doctor blades, an air knife technique or the technique known as "reverse roll".

Les conditions du choix du plastisol de PVC de-formulation non moussable, utilisé comme plastisol compact sont déterminés par les paramètres suivants :

  • la base de la formulation est du PVC de type PVC émulsion et la nature et la teneur du plastifiant doivent être tels que soit réalisée une résistance à la traction suffisante.
The conditions for choosing the non-foamable de-formulation PVC plastisol used as compact plastisol are determined by the following parameters:
  • the basis of the formulation is PVC type PVC emulsion and the nature and content of the plasticizer must be such that sufficient tensile strength is achieved.

Il est en effet apparu que l'utilisation de formulations de plastisol fortement plastifiées et chargées pour la préparation d'un voile de verre ne permettent pas de réaliser des valeurs d'adhérence supérieures à 0,5 kg/cm quel que soit le nombre de perforations par unité de surface de support.It has indeed appeared that the use of highly plasticized and loaded plastisol formulations for the preparation of a glass veil does not make it possible to achieve adhesion values greater than 0.5 kg / cm regardless of the number of perforations per unit of support surface.

La prégélification s'opère dans la plage habituelle de température de l'ordre de 120 à 150°C, tandis que l'expansion de l'enduction moussable et la gélification finale se réalisent à une température supérieure déterminée par la formulation de la composition moussable, des températures de l'ordre de 200°C étant habituelles dans ce cas.The pregelling takes place in the usual temperature range of the order of 120 to 150 ° C., while the expansion of the foamable coating and the final gelation are carried out at a higher temperature determined by the formulation of the foamable composition. , temperatures of the order of 200 ° C. being usual in this case.

Cette prégélification peut se réaliser sur un cylindre chauffé, dans un four ou par infra-rouge.This pregelification can be carried out on a heated cylinder, in an oven or by infrared.

Il doit être bien entendu que pour la réalisation de revêtements de sols décorés, il y a lieu d'intercaler dans les étapes essentielles de l'invention diverses étapes opératoires variables selon le type de produits pour obtenir un produit fini, selon les techniques classiques,It should be clearly understood that for the production of decorated floor coverings, it is necessary to insert in the essential steps of the invention various operational steps which vary according to the type of product to obtain a finished product, according to conventional techniques,

A titre d'illustration on peut par exemple prévoir la succession suivante des étapes :

  • - perforation du support;
  • - enduction d'un plastisol compact monoface ou double face sur le support perforé;
  • - prégélification, par exemple sur cylindre à 145°C;
  • - enduction d'un dos compact;
  • - prégélification par exemple sur cylindre à 145°C;
  • - application sur une face d'une enduction moussable;
  • - enduction d'une couche d'usure;
  • - expansion par exemple 3 minutes à 200°C au four.
By way of illustration, the following succession of steps can for example be provided:
  • - perforation of the support;
  • - coating of a compact single-sided or double-sided plastisol on the perforated support;
  • - pre-gelation, for example on a cylinder at 145 ° C;
  • - coating of a compact back;
  • - pre-gelation, for example on a cylinder at 145 ° C;
  • - application on one side of a foamable coating;
  • - coating of a wear layer;
  • - expansion for example 3 minutes at 200 ° C in the oven.

De nombreuses variantes opératoses sont cependant possibles pour ce qui ne constitue pas le procédé de l'invention tel qu'il a été défini.Many operatosis variants are however possible for what does not constitute the process of the invention as it has been defined.

L'invention sera encore illustrée plus en détail à l'aide des dessins schématiques d'installations convenant pour la mise en pratique de l'invention.The invention will be further illustrated in more detail using schematic drawings of installations suitable for the practice of the invention.

Selon la technique illustrée dans la figure 1, on procéde successivement à un dépôt de plasti.sol compact (2) (precoat) sur le support perforé (1), suivi d'une prégélification (3) sur cylindre chaud, à un deuxième dépôt de plastisol moussable (4) suivi d'une prégélifcation au four (5) , à une impression héliographique quatre couleurs (6), à un troisième dépôt de plastisol compact (7) à l'envers du support suivi d'une prégéli- fication sur cylindre (8) à un quatrième et dernier dépôt de plastisol non chargé et transparent (9), servant de couche d'usure, à une expansion et gélification totale de l'ensemble au four (10)..According to the technique illustrated in FIG. 1, a compact plasti.sol (2) (precoat) is deposited successively on the perforated support (1), followed by a pregelling (3) on a hot cylinder, to a second deposit. foamable plastisol (4) followed by oven pre-gelation (5), four-color heliographic printing (6), a third deposit of compact plastisol (7) on the back of the support followed by pre-gelification on cylinder (8) to a fourth and final deposit of uncharged and transparent plastisol (9), serving as a wear layer, for total expansion and gelation of the assembly in the oven (10).

Selon la technique illustrée à la figure 2, on procède successivement à un dépôt de plastisol compact (2) (precoat) sur le support perforé (1) suivi d'une prégélification sur cylindre chaud (3), à un deuxième dépôt de plastisol compact (2') au dos du support suivi d'une prégélification sur cylindre (3'), à un troisième dépôt de plastisol moussable (4) suivi d'une prégélification au four (5), à une impression héliographique quatre couleurs (6), à un quatrième dépôt de plastisol non chargé transparent (9) de couche d'usure, suivi d'une expansion de gélification totale de l'ensemble au four,According to the technique illustrated in FIG. 2, a compact plastisol deposit (2) (precoat) is successively deposited on the perforated support (1) followed by pre-gelation on hot cylinder (3), a second compact plastisol deposit (2 ') on the back of the support followed by a pregelling on a cylinder (3'), a third deposit of foamable plastisol (4) followed by a pregelling in the oven (5), a four-color heliographic printing (6) , to a fourth deposit of transparent uncharged plastisol (9) of wear layer, followed by an expansion of gelation total of the whole oven,

L'intérêt principal du procédé réside dans le fait que la technique décrite permet de réaliser des revêtements de sol au départ d'un support non poreux et ne présentant pas de réceptivité à l'égard d'agents d'accrochage chimique, de par leur nature, tel que l'amiante, certaines matières cellulosiques ou encore des feuilles métalliques,The main advantage of the process lies in the fact that the technique described makes it possible to produce floor coverings from a non-porous support and which does not have receptivity towards chemical bonding agents, due to their nature, such as asbestos, certain cellulosic materials or metallic sheets,
