Domaine Technique La présente invention a trait à un procédé pour la réalisation d'un revêtement de sol en matière plastique permettant d'obtenir non seulement de très bonnes caractéristiques de surface, mais également de ne pas altérer les caractéristiques de la structure de base constituant ledit revêtement.Technical Field The present invention relates to a process for producing a plastic floor covering making it possible not only to obtain very good surface characteristics, but also not to alter the characteristics of the basic structure constituting said structure. coating.
Techniques antérieuresPrevious techniques
Il a été proposé depuis fort longtemps de réaliser des revêtements de sol souples, en matière plastique.It has been proposed for a long time to produce flexible floor coverings, made of plastic.
D'une manière générale, de tels revêtements de sol sont constitués d'une structure de base thermoplastique, notamment en PNC plastifié, obtenue par pressage ou calandrage. Cette structure de base peut éventuellement être renforcée par une structure textile noyée dans la masse de la matière.In general, such floor coverings consist of a thermoplastic base structure, in particular made of plasticized PNC, obtained by pressing or calendering. This basic structure can possibly be reinforced by a textile structure embedded in the mass of the material.
Par ailleurs, pour améliorer le confort ou conférer des caractéristiques spécifiques au revêtement en vue de son utilisation, cette structure de base peut être associée à une sous-couche, par exemple une sous-couche en mousse.Furthermore, to improve comfort or impart specific characteristics to the covering for its use, this basic structure can be associated with an underlay, for example a foam underlay.
De plus, la face apparente est recouverte d'une couche de finition conférant à l'ensemble des propriétés spécifiques telles que résistance aux UN, tenue à l'encrassement, à la rayure, au trafic, à l'abrasion, aux traces noires de chaussures (scuffmg), à la brûlure de cigarette.In addition, the visible face is covered with a finishing layer giving the set of specific properties such as resistance to UN, resistance to fouling, scratching, traffic, abrasion, black traces of shoes (scuffmg), with cigarette burn.
Il est souhaitable que de tels revêtements puissent présenter une résistance à des taches spécifiques qui peuvent se produire sur le lieu d'utilisation, par exemple dans le domaine hospitalier (taches d'iode alcoolique, éosine alcoolique..).It is desirable that such coatings can exhibit resistance to specific stains which may occur at the place of use, for example in the hospital field (alcoholic iodine stains, alcoholic eosin, etc.).
Enfin, il est également souhaitable de supprimer les émissions de composés organiques volatiles, ce qui peut être obtenu par effet barrière de la couche supérieure de surface. our r a ser a couc e e sur ace e te s rev tements e sol, il a été envisagé depuis fort longtemps, comme cela ressort notamment du FR 2 341 021, d'utiliser une composition soit à base d'une matière thermoplastique, PVC éventuellement chargé, soit d'une matière thermodurcissable en polyuréthanne réticulé notamment.Finally, it is also desirable to suppress the emissions of volatile organic compounds, which can be obtained by the barrier effect of the upper surface layer. our ra ser a couc ee on ace e te s t coverings e soil, it has been envisaged for a very long time, as is clear in particular from FR 2 341 021, to use a composition either based on a thermoplastic material, PVC possibly loaded, either with a thermosetting material in crosslinked polyurethane in particular.
Le procédé décrit dans ce document est cependant complexe à mettre en œuvre.The process described in this document is however complex to implement.
De très nombreuses propositions ont également été faites pour réaliser des couches de surface réalisées à partir de polymères synthétiques différents comme cela ressort de FUS 4 337 296, de l'EP 794 281, du GB 2 285 012.Numerous proposals have also been made to produce surface layers produced from different synthetic polymers as is apparent from FUS 4,337,296, from EP 794,281, from GB 2,285,012.
Dans toutes ces propositions, le problème qui se pose est celui de pouvoir réaliser une bonne adhérence entre la couche de surface en matériau thermodurcissable et la structure de base thermoplastique, ainsi que de ne pas altérer les caractéristiques de cette structure de base.In all of these proposals, the problem that arises is that of being able to achieve good adhesion between the surface layer of thermosetting material and the thermoplastic base structure, as well as not to alter the characteristics of this base structure.
Or, on a trouvé, et c'est ce qui fait l'objet de la présente invention, un procédé perfectionné qui permet de résoudre l'ensemble de ces problèmes.However, we have found, and this is what is the subject of the present invention, an improved method which makes it possible to solve all of these problems.
Exposé de l'inventionStatement of the invention
D'une manière générale, le procédé conforme à l'invention pour la réalisation d'un revêtement de sol consiste :In general, the method according to the invention for producing a floor covering consists of:
" dans une première phase opératoire, à réaliser de manière conventionnelle une structure de base en PNC plastifié, par pressage, calandrage, extrusion ou enduction, éventuellement renforcée par une armature textile et/ou associée à une sous-couche additionnelle ; puis"in a first operational phase, to produce in a conventional manner a basic structure in plasticized PNC, by pressing, calendering, extrusion or coating, possibly reinforced by a textile reinforcement and / or associated with an additional undercoat; then
1 dans une deuxième phase opératoire, à réaliser un revêtement de surface constitué par un complexe bicouche comportant une couche thermoplastique revêtue d'un film à base d'un polymère thermodurcissable. 1 in a second operating phase, to produce a surface coating consisting of a two-layer complex comprising a thermoplastic layer coated with a film based on a thermosetting polymer.
Dans le procédé conforme à l'invention, le complexe bicouche constituant le revêtement de surface est formé, soit en continu et en ligne avec la réalisation de la structure de base, soit sur un support transfert permettant un complexage lors d'une phase ultérieure par : " p t sur a ace sup r eure u complexe de base, ou sur un support transfert, d'une couche de plastisol de PNC, transparent ou coloré, que l'on prégélifie par traitement thermique ;In the process according to the invention, the two-layer complex constituting the surface coating is formed, either continuously and in line with the production of the basic structure, or on a transfer support allowing complexing during a subsequent phase by : "pt on a ace sup r eure u base complex, or on a transfer support, a layer of PNC plastisol, transparent or colored, which is pre-gelified by heat treatment;
" en continu, recouvrement de la couche de plastisol pré-gélifiée d'une couche de poudre thermodurcissable suivi d'un traitement thermique transformant ladite poudre en un film continu liquide ;"continuously, covering the layer of pre-gelled plastisol with a layer of thermosetting powder followed by a heat treatment transforming said powder into a continuous liquid film;
' passage du complexe ainsi formé dans un four à air chaud, entraînant la gélification et la réticulation finale des deux constituants de la couche de surface, l'ensemble étant ensuite éventuellement graine et réceptionné.passage of the complex thus formed in a hot air oven, resulting in gelation and final crosslinking of the two constituents of the surface layer, the assembly then possibly being seeded and received.
Pour la mise en œuvre de ce procédé, la couche thermoplastique à base de PNC du complexe de surface, est obtenue à 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 0,1 et 2 mm et préférentiellement 0,2 à 0,8 mm. Ce plastisol peut également être réalisé à l'aide de résine acrylique dans un plastifiant.For the implementation of this process, the PNC-based thermoplastic layer of the surface complex is obtained from a composition of PVC plastisol (PVC resin, plasticizer, and conventional stabilizing and rheology additives), this layer of surface being colored or transparent and having a thickness of between 0.1 and 2 mm and preferably 0.2 to 0.8 mm. This plastisol can also be produced using acrylic resin in a plasticizer.
Le plastisol est ensuite prégélifié par traitement thermique à une température comprise entre 120°C et 130°C pendant trente à soixante secondes par passage dans un four à ai chaud ou infrarouge.The plastisol is then pregelified by heat treatment at a temperature between 120 ° C and 130 ° C for thirty to sixty seconds by passing through a hot or infrared oven.
La couche externe associée à cette couche à base de PVC est, quant à elle, réalisée à partir d'une composition de poudre thermodurcissable présentant des caractéristiques de réticulation (durcissement) de courte durée, comprise entre une et sept minutes au maximum à 210°C.The outer layer associated with this PVC-based layer, for its part, is produced from a thermosetting powder composition having short-term crosslinking (hardening) characteristics, between one and seven minutes at most at 210 °. vs.
La formulation de cette poudre est telle qu'elle permette l'adhésion sur le polymère plastifié (PVC) sans altérer les qualités de souplesse, le durcisseur étant également non agressif vis-à-vis du PVC.The formulation of this powder is such that it allows adhesion to the plasticized polymer (PVC) without altering the qualities of flexibility, the hardener also being non-aggressive with respect to PVC.
Une telle poudre peut être obtenue à partir d'une composition comprenant : " une résine polyester hydroxylée, une résine polyester carboxylée, une résine polyuréthanne, une résine hybride polyester/ epoxy... ; " un réticulant de type glycidylester, un réticulant de type hydroxyalkylamide, un réticulant de type isocyanate bloqué ou dimérisée.Such a powder can be obtained from a composition comprising: "a hydroxylated polyester resin, a carboxylated polyester resin, a polyurethane resin, a polyester / epoxy hybrid resin, etc .; "a glycidylester type crosslinker, a hydroxyalkylamide type crosslinker, a blocked or dimerized isocyanate type crosslinker.
Le dépôt de la poudre thermodurcissable est de préférence réalisé par saupoudrage électrostatique à raison de 20 à 200 g/m^.The deposition of the thermosetting powder is preferably carried out by electrostatic dusting at a rate of 20 to 200 g / m 2.
Cette poudre est transformée en un film liquide par un traitement thermique réalisé en combinant l'action d'une rampe à rayonnement infrarouge suivie d'un passage dans un tunnel à air chaud.This powder is transformed into a liquid film by a heat treatment carried out by combining the action of a ramp with infrared radiation followed by passage through a hot air tunnel.
Une telle manière de procéder permet de former un film très régulier et continu qui s'explique par le fait que le rayonnement infrarouge provoque une fusion rapide de la poudre et que l'action de l'air chaud entraîne le lissage du film.Such a procedure makes it possible to form a very regular and continuous film which is explained by the fact that the infrared radiation causes a rapid melting of the powder and that the action of hot air results in the smoothing of the film.
Ce traitement thermique est fonction de la nature de la poudre thermodurcissable, le rayonnement infrarouge portant cette dernière à une température comprise entre 110°C et 200°C pendant une durée comprise entre une à trente secondes, alors que le traitement par air chaud est effectué à une température pouvant varier de 80 à 120°C pendant une durée de trente secondes à une minute.This heat treatment is a function of the nature of the thermosetting powder, the infrared radiation bringing the latter to a temperature between 110 ° C and 200 ° C for a period of between one to thirty seconds, while the hot air treatment is carried out. at a temperature which can vary from 80 to 120 ° C for a period of thirty seconds to one minute.
Après traitement, le film de surface en polymère thermodurcissable, de préférence à base de copolyester, a une épaisseur comprise entre 15 et 150 μm et de préférence entre 30 et 80 μm.After treatment, the surface film of thermosetting polymer, preferably based on copolyester, has a thickness of between 15 and 150 μm and preferably between 30 and 80 μm.

Dans la suite de la description, l'invention sera décrite pour la réalisation d'un revêtement de surface en continu avec la production de la structure de base du revêtement de sol, étant entendu que cette couche de surface pourrait être réalisée lors d'une phase séparée sur un support transfert pour être associée à la couche de base lors de la formation de cette dernière.In the following description, the invention will be described for producing a continuous surface coating with the production of the basic structure of the floor covering, it being understood that this surface layer could be produced during a separate phase on a transfer support to be associated with the base layer during the formation of the latter.
En se référant aux figures annexées, dans une première phase opératoire, on réalise, de manière conventionnelle, par pressage, calandrage, extrusion ou enduction, une structure de base (1) en PVC.Referring to the appended figures, in a first operational phase, a basic structure (1) is made of PVC, by pressing, calendering, extrusion or coating.
Une telle structure de base (1) peut être renforcée par une couche en matière textile, et peut comporter sur sa face envers, une sous-couche telle qu'une couche de mousse (la).Such a basic structure (1) can be reinforced by a layer of textile material, and can comprise on its reverse side, an under-layer such as a layer of foam (la).
Conformément à l'invention, le revêtement de surface du complexe de base (1) ainsi formé, est réalisé en déposant sur la face supérieure de ce support (1), une couche régulière (2) d'un plastisol à base d'une matière thermoplastique, PVC notamment, mais qui peut être aussi un plastisol acrylique.In accordance with the invention, the surface coating of the base complex (1) thus formed is produced by depositing on the upper face of this support (1), a regular layer (2) of a plastisol based on a thermoplastic material, PVC in particular, but which can also be an acrylic plastisol.
Ce dépôt de plastisol est réalisé de manière conventionnelle en faisant passer le support (1) sur un rouleau (3) associé à une racle (4).This plastisol deposition is carried out in a conventional manner by passing the support (1) over a roller (3) associated with a doctor blade (4).
La couche de plastisol (2) a une épaisseur comprise entre 0,2 et 0,8 mm.The plastisol layer (2) has a thickness of between 0.2 and 0.8 mm.
En continu, on soumet l'ensemble à un traitement thermique de pré- gélification portant la matière à une température comprise entre 120 et 130°C pendant 30 à 60 secondes par passage dans un four à air chaud ou infrarouge (5).The assembly is continuously subjected to a gelation heat treatment bringing the material to a temperature between 120 and 130 ° C for 30 to 60 seconds by passage through a hot air or infrared oven (5).
On dépose ensuite sur cette couche de plastisol (2) prégélifiée et donc durcie, une composition de poudre thermodurcissable (7).A thermosetting powder composition (7) is then deposited on this pregastified and therefore hardened plastisol layer (2).
Ce dépôt est réalisé par saupoudrage électrostatique au moyen d'un système de poudrage qui peut être une trémie (6) associée à un ensemble de charge électrostatique ou un système de pistoletage électrostatique adapté au poudrage à p at. e p es r a s ra son e g m , e pr rence entre et 100 g/m2.This deposition is carried out by electrostatic dusting by means of a dusting system which can be a hopper (6) associated with an electrostatic charge assembly or an electrostatic spraying system suitable for dusting at p at. ep es ras ra son egm, e presence between and 100 g / m 2 .
La poudre est ensuite transformée en un film continu liquide (9) par un traitement thermique (8). Ce traitement thermique combine à la fois l'action d'une rampe à infrarouge entraînant la fusion de la poudre, suivie d'un passage dans un tunnel à air chaud entraînant un lissage du film formé.The powder is then transformed into a continuous liquid film (9) by a heat treatment (8). This heat treatment combines both the action of an infrared ramp causing the powder to melt, followed by passage through a hot air tunnel resulting in a smoothing of the film formed.
En fonction de la nature de la poudre, le rayonnement infrarouge porte cette dernière à une température comprise entre 110°C et 200°C, et ce pendant une durée de une à trente secondes, alors que le passage dans l'air chaud, porté à une température comprise entre 80 et 120°C, est effectué pendant une durée de trente secondes à une minute.Depending on the nature of the powder, the infrared radiation brings the latter to a temperature between 110 ° C and 200 ° C, and this for a period of one to thirty seconds, while the passage through hot air, brought at a temperature between 80 and 120 ° C, is carried out for a period of thirty seconds to one minute.
L'épaisseur du film est comprise entre 15 μm et 150 μm, de préférence entreThe thickness of the film is between 15 μm and 150 μm, preferably between
30 et 80 μm.30 and 80 μm.
Le complexe ainsi formé est ensuite soumis à un traitement thermique à l'intérieur d'un four à air chaud (11), entraînant la gélification et réticulation finale des deux constitutants (2,9) de la couche de surface.The complex thus formed is then subjected to a heat treatment inside a hot air oven (11), resulting in gelation and final crosslinking of the two constituents (2,9) of the surface layer.
La température à l'intérieur du four est réglée entre 200°C et 210°C, la durée de traitement étant comprise entre une à sept minutes.The temperature inside the oven is set between 200 ° C and 210 ° C, the treatment time being between one to seven minutes.
Le complexe ainsi formé est ensuite réceptionné, par exemple sous la forme d'un enroulement.The complex thus formed is then received, for example in the form of a coil.
La figure 2 montre en coupe, de manière schématique, la structure générale d'un tel revêtement de sol, comportant donc un support de base (1) recouvert d'une structure transparente bicouche constituée, d'une part, d'une couche thermoplastique (2), de préférence en PVC plastifié, associée à un film (9) à base d'une matière thermodurcissable, polyester notamment.Figure 2 shows in section, schematically, the general structure of such a floor covering, therefore comprising a base support (1) covered with a transparent bilayer structure consisting, on the one hand, of a thermoplastic layer (2), preferably made of plasticized PVC, associated with a film (9) based on a thermosetting material, in particular polyester.
Ainsi que cela ressort de cette figure, dans un tel complexe, les différentes couches sont intimement liées les unes aux autres sans cependant interpénétration des constituants de l'une des couches dans la couche adjacente, ce qui permet de conserver toutes les caractéristiques de chacune des couches.As can be seen from this figure, in such a complex, the different layers are intimately linked to each other without, however, interpenetration constituents of one of the layers in the adjacent layer, which makes it possible to preserve all the characteristics of each of the layers.
Exemple Au moyen d'une installation telle que décrite précédemment, on réalise le revêtement de surface d'une structure de base (1) préalablement réalisée, comprenant une sous-couche en mousse (la) associée à l'envers d'une feuille (lb) en PVC éventuellement renforcé par une structure textile.Example By means of an installation as described above, the surface covering of a basic structure (1) previously produced, comprising a foam underlay (la) associated with the back of a sheet ( lb) PVC possibly reinforced by a textile structure.
Un tel support (1) a une épaisseur de 15 mm.Such a support (1) has a thickness of 15 mm.
A la surface de ce support (1), on dépose à la racle (4), une couche de 625 g/m2 d'un plastisol présentant une viscosité de 10 Pa.s (10 000 cPs) pour un cisaillement de 100 s~l à l'aide de l'équipement Rheomat ayant la composition suivante :On the surface of this support (1), a layer of 625 g / m 2 of a plastisol having a viscosity of 10 Pa.s (10,000 cPs) is deposited with a doctor blade (4) for a shear of 100 s ~ l using Rheomat equipment having the following composition:
_ chlorure de polyvinyle (100 parties) _ plastifiant de type phtalate de dioctyle (DOP) à 40 pcr _ stabilisant de type butylétain soufré à 2 pcr _ diluant._ polyvinyl chloride (100 parts) _ plasticizer of dioctyl phthalate type (DOP) at 40 pcr _ stabilizer of butyltin type sulfur at 2 pcr _ diluent.
On forme ainsi à la surface du support (1) une couche ayant une épaisseur de 0,5 mm.A layer having a thickness of 0.5 mm is thus formed on the surface of the support (1).
L'ensemble est alors soumis à un traitement thermique par passage sous une rampe à infrarouge (5) portant la matière à une température de 1 10°C entraînant la pré-gélification, donc le durcissement de cette couche.The assembly is then subjected to a heat treatment by passing under an infrared ramp (5) bringing the material to a temperature of 110 ° C. causing the pre-gelling, therefore the hardening of this layer.
En aval de la rampe à infrarouge, on dépose, à raison de 60 g/m2, une poudre thermodurcissable constituée par une composition à base de copolyester comprenant :Downstream of the infrared ramp, a thermosetting powder consisting of a copolyester-based composition comprising: 60 g / m 2 is deposited
• résine de type polyester hydroxylé• hydroxylated polyester type resin
• durcisseur de type isocyanate dimérisée.• dimerized isocyanate type hardener.
Le complexe est soumis à un second traitement thermique (8) combinant l'action d'une rampe à infrarouge portant la matière à 120°C pendant dix secondes, su v e un tra tement ans un tunne a r c au port pen ant une ur e e quarante secondes, permettant d'obtenir un film (9) ayant une épaisseur de l'ordre de 50 μm.The complex is subjected to a second heat treatment (8) combining the action of an infrared ramp bringing the material to 120 ° C. for ten seconds, following a treatment in an arc tunnel at port for a period of forty seconds, making it possible to obtain a film (9) having a thickness of the order of 50 μm.
Le revêtement ainsi formé passe ensuite dans un four à air chaud (11) porté à une température de 200°C, la durée de traitement étant de 3 minutes.The coating thus formed then passes through a hot air oven (11) brought to a temperature of 200 ° C., the treatment time being 3 minutes.
En sortie de l'installation, on obtient un revêtement de sol tel que illustré à la figure 2, ayant une épaisseur totale de 2 mm.At the outlet of the installation, a floor covering is obtained as illustrated in FIG. 2, having a total thickness of 2 mm.
Un tel revêtement de sol présente de très bonnes propriétés de surface, notamment en ce qui concerne la tenue à l'encrassement, à la rayure, à l'abrasion, au trafic, aux UN.Such a floor covering has very good surface properties, in particular with regard to resistance to fouling, scratching, abrasion, traffic and UN.
II présente par ailleurs une très bonne résistance aux taches. It also has very good stain resistance.
