More specifically, it relates to a new type of pressed, calendered, extruded, coated or printed flooring having improved surface characteristics.
<U>Techniques antérieures</U> <B>Il</B> a été propose depuis fort longtemps de réaliser des revêtements de sol souples, en matière plastique. <U> Prior techniques </ U> <B> It </ B> has been proposed for a very long time to realize flexible flooring, plastic.
D'une manière 2énérale, de tels revêtements sont constitués d'une structure de base thermoplastique et notamment en PVC plastifié, qui peut éventuellement être renforcée par structure textile noyée dans la masse de la matière. In a general manner, such coatings consist of a thermoplastic base structure and in particular plasticized PVC, which may optionally be reinforced by textile structure embedded in the mass of the material.
Par ailleurs pour améliorer le confort ou conférer des caractéristiques spécifiques au revêtement, celui-ci peut être associé<B>à</B> une sous-couche, par exemple une sous-couche en mousse. In addition, to improve the comfort or to confer specific characteristics to the coating, it may be associated with an underlayer, for example a foam underlayer.
De plus, la face apparente est recouverte d'une couche de finition conférant<B>à</B> l'ensemble des propriétés spécifiques telles que résistance aux UV, tenue<B>à</B> l'encrassement,<B>à</B> la rayure, au trafic,<B>à</B> l'abrasion...<B>.</B> In addition, the apparent face is covered with a topcoat conferring <B> to </ B> all specific properties such as UV resistance, holding <B> to </ B> fouling, <B > scratch, traffic, abrasion ... <B>. </ B>
Une telle couche de surface peut être réalisée soit en continu avec la fabrication de la structure de base plastifiée, soit lors d'une phase séparée sur un support transfert. Such a surface layer can be made either continuously with the manufacture of the plasticized base structure, or during a separate phase on a transfer medium.
<U>Exposé de l'invention</U> Or, on a trouvé, et c'est ce qui fait l'objet de la présente invention, un perfectionnement apporté<B>à</B> de tels revêtements, qui permet d'améliorer très sensiblement les propriétés surfaciques de tenue<B>à</B> l'encrassement,<B>à</B> la rayure, au trafic,<B>à</B> l'abrasion, aux traces noires de chaussures (scuffing). Un tel revêtement présente par ailleurs une résistance<B>à</B> des taches spécifiques qui peuvent se produire sur le lieu d'utilisation, par exemple dans le domaine hospitalier (taches d'iode alcoolique, éosine alcoolique<B>... ).</B> <U> Exposure of the invention </ U> However, it has been found, and this is the subject of the present invention, an improvement brought <B> to </ B> such coatings, which allows to improve very significantly the surface properties of behavior <B> to </ B> fouling, <B> to </ B> the scratch, the traffic, <B> to </ B> the abrasion, to the traces black shoes (scuffing). Such a coating also has a resistance <B> to </ B> specific spots that may occur at the place of use, for example in the hospital field (alcoholic iodine spots, alcoholic eosin <B> .. .). </ B>
Par ailleurs, le revêtement conforme<B>à</B> l'invention permet en outre de diminuer, voire de supprimer les émissions de composés organiques volatiles par effet barrière de la couche supérieure de surface. Furthermore, the coating conforming to the invention also makes it possible to reduce or even eliminate emissions of volatile organic compounds by the barrier effect of the upper surface layer.
une manière générale, le revêtement conforme<B>à</B> l'invention comporte une structure de base thermoplastique, en PVC notamment, pressée, calandrée, extradée, enduite ou imprimée, éventuellement renforcée par une armature textile et pouvant comporter sur sa face envers une sous-couche telle qu'une couche de mousse et dont la face apparente est constituée d'une couche de surface associée<B>à</B> ladite structure de base. in general, the coating conforming to the invention comprises a thermoplastic base structure, in particular PVC, pressed, calendered, extruded, coated or printed, optionally reinforced by a textile reinforcement and may include on its against a sub-layer such as a layer of foam and whose apparent face consists of a surface layer associated with said basic structure.

The coating according to the invention is characterized in that the surface layer is constituted by a bilayer complex, comprising a thermoplastic layer, preferably <B> based on plasticized PVC, coated with a <B> to </ B> base of a thermosetting polymer, especially polyester.
Conformément<B>à</B> l'invention, la couche thermoplastique de surface a base de PVC est obtenue<B>à</B> partir d'une composition de PVC plastisol (résine PVC, plastifiant, et additifs stabilisants et de rhéologie conventionnels), cette couche de surface étant colorée ou transparente et ayant une épaisseur comprise entre<B>0,1</B> et 2 mm et préférentiellement<B>0,3 à 0,8</B> mm. Ce plastisol peut également être réalisé<B>à</B> l'aide de résine acrylique dans un plastifiant. According to the invention, the PVC-based thermoplastic surface layer is obtained from a plastisol PVC composition (PVC resin, plasticizer, and stabilizing additives and conventional rheology), this surface layer being colored or transparent and having a thickness between <B> 0.1 </ B> and 2 mm and preferably <B> 0.3 to 0.8 </ B> mm. This plastisol can also be made by using acrylic resin in a plasticizer.
La couche externe associée<B>à</B> cette couche<B>à</B> base de PVC est, quant<B>à</B> elle, réalisée<B>à</B> partir d'une composition de poudre thermodurcissable présentant des caractéristiques de réticulation (durcissement) de courte durée, comprise entre une et sept minutes au maximum<B>à</B> 2<B>1</B> O'C. The outer layer associated with this <B> to </ B> base layer of PVC is, when <B> to </ B> it, made <B> to </ B> from a thermosetting powder composition having short-term cross-linking (curing) characteristics of from one to seven minutes at most <B> to </ B> 1 <B> 1 </ B> O'C.
formulation de cette poudre est telle qu'elle permette l'adhésion sur le polymère plastifié (PVQ sans altérer les qualités de souplesse, le durcisseur étant également non agressif vis-à-vis du PVC. Une telle poudre peut être obtenue<B>à</B> partir d'une composition comprenant<B>:</B> # -une résine polyester hydroxylée, une résine polyester carboxylée., une résine polyuréthanne, une résine hybride polyester/epoxy <B>... ;</B> # un réticulant de typ e glycidylester, un réticulant de type hydroxyalkylamide, un réticulant de type isocyanate bloqué ou dimérisée. Après réalisation, le film de surface en polymère thermodurcissable, de préférence<B>à</B> base de copolyester, a une épaisseur comprise entre<B>15</B> et #tm et de préférence entre<B>30</B> et<B>80</B> #im. formulation of this powder is such that it allows adhesion to the plasticized polymer (PVQ without altering the qualities of flexibility, the hardener is also non-aggressive vis-à-vis PVC.This powder can be obtained <B> to From a composition comprising: a hydroxylated polyester resin, a carboxylated polyester resin, a polyurethane resin, a hybrid polyester / epoxy resin, and the like; B> # a glycidyl ester crosslinking agent, a crosslinking agent of the hydroxyalkylamide type, a blocked or dimerized isocyanate type crosslinking agent After production, the thermosetting polymer surface film, preferably a copolyester based film, has a thickness between <B> 15 </ B> and #tm and preferably between <B> 30 </ B> and <B> 80 </ B> #im.
L'invention concerne également un procédé pour la réalisation tel revêtement. The invention also relates to a method for producing such a coating.
D'une manière générale, conformément<B>à</B> l'invention, lors d'une première phase opératoire, on réalise de manière conventionnelle une structure de base en PVC plastifié, par pressage, calandrage, extrusion ou enduction, renforcée non par armature textile (non tissé cellulosique ou de verre, grille tissée ou non tissée..), associée ou non<B>à</B> une sous-couche additionnelle,<B>à</B> base de mousse par exemple. In a general manner, according to the invention, during a first phase of operation, a base structure of plasticized PVC is produced in a conventional manner, by pressing, calendering, extrusion or coating, reinforced not by textile reinforcement (non-woven cellulose or glass, woven or non-woven mesh, etc.), whether or not associated with an additional sub-layer, foam base with example.
