Abstract

A plastic material in sheet form, partic. for use as garden flagstones consists of two layers of polyolefin meshes and an intermediate layer of woven, knitted or non-woven plastic material, partic. polypropylene. The two mesh layers are extruded separately and are joined to the inner layer by gluing or heat sealing, notably by softening the surfaces by flaming the boundary. The mesh material is biplanar and has anti-slip properties on the outer surface.

Description

La présente invention est relative à un matériau en nappe en matière plastique destiné en particulier a la réalisation de dalles de jardin à mettre en place notamment sur des pelouses engazonnées. The present invention relates to a plastic sheet material intended in particular for the production of garden tiles to be installed in particular on grassed lawns.

On connaît pour cette application des dalles en pierre ou en béton, ou encore des dalles moulées en matière plastique généralement munies de perforations pour permettre le passage de l'eau ainsi que la pousse du gazon au travers de la dalle. Known for this application of stone or concrete slabs, or molded plastic slabs generally provided with perforations to allow the passage of water and the growth of lawn through the slab.

Les dalles connues sont généralement lourdes et conteuses et nécessitent pour leur mise en place une préparation relativement longue du terrain. Known slabs are generally heavy and storytelling and require relatively long preparation of the ground for their installation.

La présente invention se propose de fournir un matériau en nappe en matière plastique permettant de réaliser des dalles qui, tout en étant plus légères et plus économiques que les dalles connues, présentent les qualités de résistance et de stabilité nécessaires. Les dalles obtenues à partir du matériau selon l'invention permettent, comme les dalles perforées connues, le passage de l'eau et la pousse du gazon, et ce, sans nécessiter de préparation importante du terrain ni nécessiter des organes particuliers pour la fixation des dalles dans le sol. The present invention proposes to provide a plastic sheet material making it possible to produce slabs which, while being lighter and more economical than known slabs, have the necessary strength and stability qualities. The slabs obtained from the material according to the invention allow, like the known perforated slabs, the passage of water and the growth of the lawn, without requiring significant preparation of the ground or requiring special organs for fixing the slabs in the ground.

La présente invention a pour objet un matériau en nappe en matière plastique, caractérisé par le fait qu'il comporte deux couches en matière plastique, notamment en polyoléfine, à structure réticulaire et une couche intermédiaire sous la forme d'une feuille tissée, tricotée ou non tissée en matière plastique, les deux couches à structure réticulaire étant obtenues séparément par extrusion et solidarisées de la couche intermédiaire par collage ou thermofusion, notamment par ramollissement superficiel par flammage des couches à structure réticulaire. The subject of the present invention is a sheet material of plastic material, characterized in that it comprises two layers of plastic material, in particular of polyolefin, with a reticular structure and an intermediate layer in the form of a woven, knitted or non-woven plastic, the two layers with a reticular structure being obtained separately by extrusion and joined to the intermediate layer by bonding or thermofusion, in particular by surface softening by flame of the layers with a reticular structure.

Les couches à structure réticulaire sont de préférences obtenues par extrusion de matière plastique, notamment de polyéthylène, par le procédé connu sous le nom de NETLON et qui permet notamment de réaliser des structures réticulaires biplanaires formées de deux ensembles de brins croisés de section relativement importante. The layers with a reticular structure are preferably obtained by extruding plastic material, in particular polyethylene, by the process known under the name of NETLON and which in particular makes it possible to produce biplanar reticular structures formed from two sets of crossed strands of relatively large section.

Ce procédé consiste à produire une structure réticulaire par découpe d'une gaine tubulaire obtenue à l'aide d'un dispositif d'extrusion continue comprenant deux éléments de filière concentriques tournant en sens contraires. This method consists in producing a reticular structure by cutting a tubular sheath obtained using a continuous extrusion device comprising two concentric die elements rotating in opposite directions.

L'un des élément de filière, comprend une pluralité de crans périphériques dont la section correspond à la section voulue pour les brins d'un des ensembles de brins de la structure, l'autre élément de filière présentant une pluralité de crans dont la section correspond à la section voulue pour les brins de l'autre ensemble de brins de la structure, les crans des différents éléments de filière communiquant avec des canaux d'amenée de la matière plastique ramollie en provenance d'une extrudeuse. One of the die elements comprises a plurality of peripheral notches, the section of which corresponds to the desired section for the strands of one of the sets of strands of the structure, the other die element having a plurality of notches, the section of which corresponds to the desired section for the strands of the other set of strands of the structure, the notches of the different die elements communicating with supply channels of the softened plastic material coming from an extruder.

Les brins de l'un des ensembles de brins constituent des filaments hélicoïdaux auxquels adhèrent les brins de l'autre ensemble de brins sous forme de filaments hélicoïdaux de façon à former une structure réticulaire. The strands of one of the sets of strands constitute helical filaments to which the strands of the other set of strands adhere in the form of helical filaments so as to form a reticular structure.

Les deux couches à structure réticulaire du matériau selon l'invention peuvent cependant être réalisées par tout autre procédé connu d'extrusion continu permettant d'obtenir une structure réticulaire et peuvent être réalisées en tout autre matériau approprié, par exemple en polypropylène. The two layers with a reticular structure of the material according to the invention can however be produced by any other known continuous extrusion process making it possible to obtain a reticular structure and can be produced from any other suitable material, for example polypropylene.

La couche intermédiaire peut être réalisée en tout matériau approprié, notamment en géotextile, tissé ou non tissé, en particulier en géotextile non tissé de polypropylène aiguilleté d'une épaisseur de 1,3 mm, ou une feuille tissée de polypropylène d'une épaisseur de 0,4 mm
La couche intermédiaire sert, dans la pratique, d'armature assurant la cohésion des couches extérieures à structure réticulaire.The intermediate layer can be made of any suitable material, in particular geotextile, woven or nonwoven, in particular nonwoven geotextile of needled polypropylene with a thickness of 1.3 mm, or a woven sheet of polypropylene with a thickness of 0.4 mm
The intermediate layer serves, in practice, as a reinforcement ensuring the cohesion of the outer layers with a reticular structure.

Le matériau selon l'invention peut être facilement découpé aux dimensions voulues pour des dalles. The material according to the invention can be easily cut to the dimensions desired for slabs.

Pour la pose de celles-ci, il suffit d'appliquer le matériau sur le sol, le matériau s'enfonçant facilement de l'épaisseur de la couche à structure réticulaire inférieure jusqu'à ce que la feuille intermédiaire affleure au niveau du sol. For the installation of these, it suffices to apply the material to the ground, the material easily sinking the thickness of the layer with a lower reticular structure until the intermediate sheet is flush with the ground.

La structure des couches permet un passage aisé de l'eau au travers des dalles ainsi qu'une pousse du gazon à travers elles. The structure of the layers allows easy passage of water through the tiles as well as a push of the grass through them.

On peut envisager selon l'invention, pour la réalisation de dalles très épaisses de multiplier les couches à structure réticulaire avec interposition entre chaque paire de telles couches d'une couche formée d'une feuille tissée ou non tissée. It is conceivable according to the invention, for the production of very thick slabs, to multiply the layers with a reticular structure with the interposition between each pair of such layers of a layer formed of a woven or nonwoven sheet.

Afin de conférer au matériau selon l'invention des propriétés antiglissantes au niveau d'une surface supérieure, il est avantageux de solidariser a l'une des couches & structure réticulaire une couche externe à structure réticulaire en matière plastique présentant des propriétés antiglissantes, la couche externe étant obtenue séparément par extrusion et solidarisée de la couche sous-jacente par collage ou thermofusion, notamment par ramollissement superficiel par flammage de la couche à structure réticulaire sous-jacente.  In order to give the material according to the invention anti-slip properties at the level of an upper surface, it is advantageous to join to one of the layers & reticular structure an external layer with reticular structure in plastic material having anti-slip properties, the layer external being obtained separately by extrusion and secured to the underlying layer by bonding or thermofusion, in particular by surface softening by flame of the layer with an underlying reticular structure.

La couche externe présente une épaisseur faible par rapport à la couche à structure réticulaire sous-jacente, le rapport des épaisseurs de la couche à structure réticulaire sous-jacente et de la couche externe étant avantageusement compris entre 2 et 30. The outer layer has a small thickness compared to the layer with an underlying reticular structure, the ratio of the thicknesses of the layer with an underlying reticular structure and the outer layer being advantageously between 2 and 30.

La couche externe est avantageusement une couche monoplanaire & mailles carrées ou losanges présentant en particulier une épaisseur comprise entre 4 mm et 15 mm. The outer layer is advantageously a monoplanar layer with square or diamond meshes having in particular a thickness of between 4 mm and 15 mm.

La couche externe peut être réalisée par extrusion continue, par le procédé NETLON mentionné ci-dessus, ou par tout autre procédé connu permettant d'obtenir une structure réticulaire, sensiblement monoplanaire, par extrusion continue d'une matière thermoplastique constituée totalement ou en partie d'un produit thermoplastique présentant des propriétés antiglissantes. The outer layer can be produced by continuous extrusion, by the NETLON method mentioned above, or by any other known method making it possible to obtain a reticular, substantially monoplanar structure, by continuous extrusion of a thermoplastic material made wholly or partly of '' a thermoplastic product with non-slip properties.

A titre de produits thermoplastiques présentant des propriétés antiglissantes utilisables pour réaliser la couche externe du matériau selon la présente invention, on peut citer 1'EVA (éthylène-acétate de vinyle). As thermoplastic products having non-slip properties which can be used to produce the external layer of the material according to the present invention, mention may be made of EVA (ethylene vinyl acetate).

Ces produits thermoplastiques peuvent être utilisés seuls ou en mélange, dans des proportions comprises entre 10% et 100% en poids avec des matières thermoplastiques telles que le polyéthylène. These thermoplastic products can be used alone or as a mixture, in proportions of between 10% and 100% by weight with thermoplastic materials such as polyethylene.

Le matériau selon l'invention peut être fabriqué industriellement en conditionnant au préalable les structures destinées à former les couches du matériau en rouleaux, et en déroulant en continu les différentes couches à partir de leurs rouleaux respectifs, le matériau formé par solidarisation des couches étant lui-même conditionné en rouleau. The material according to the invention can be manufactured industrially by preconditioning the structures intended to form the layers of the material in rolls, and by continuously unwinding the various layers from their respective rolls, the material formed by joining the layers being itself - even packaged in a roll.

La solidarisation des couches du matériau selon l'invention peut s'effectuer par flammage, en faisant passer en continu les couches à structure réticulaire devant une rampe de brûleurs pour en chauffer une face et le cas échéant les deux faces lorsqu'une couche antiglissement est prévue et en appliquant en continu entre deux rouleaux presseurs les unes contre les autres les couches constitutives du matériau. On peut en particulier utiliser un dispositif comportant deux rouleaux presseurs et deux rampes de brûleurs disposées chacune en regard d'un des rouleaux presseurs, chacune des couches à structure réticulaire étant amenée à passer autour de l'un desdits rouleaux presseurs jusque dans l'intervalle entre les rouleaux, intervalle dans lequel on fait passer linéairement la couche intermédiaire entre les deux couches à structure réticulaire dont les faces chauffées par les rampes de brûleurs respectives s'appliquent de part et d'autre de la couche intermédiaire.  The layers of the material according to the invention can be joined together by flaming, by continuously passing the layers with a reticular structure in front of a burner bank to heat one side and, where appropriate, both sides when an anti-slip layer is provided and applying continuously between two pressure rollers against each other the constituent layers of the material. It is in particular possible to use a device comprising two pressure rollers and two burner ramps each disposed opposite one of the pressure rollers, each of the layers with a reticular structure being caused to pass around one of said pressure rollers until in the interval between the rollers, the interval in which the intermediate layer is passed linearly between the two layers with a reticular structure, the faces heated by the respective burner banks apply on either side of the intermediate layer.

En variante, la solidarisation des couches du matériau selon l'invention peut s'effectuer par collage, avec ou sans application de pression, notamment en utilisant des adhésifs de type Hot-Melt. As a variant, the layers of the material according to the invention can be joined together by bonding, with or without the application of pressure, in particular using adhesives of the Hot-Melt type.

A titres d'exemple, on a réalisé un matériau utilisable pour la réalisation de dalles en solidarisant par flammage deux couches à structure réticulaire constituées par le produit commercialisé par la société déposante sous la référence 5877 et constituées par une grille en polyéthylène haute densité, biplanaire, présentant une épaisseur de 4,5 mm et des mailles de 8 mm de côté, avec une couche intermédiaire réalisée en polypropylène présentant une épaisseur de 1,3 mm. By way of example, a material has been produced which can be used for the production of slabs by joining two layers with a reticular structure by flame formation constituted by the product marketed by the applicant company under the reference 5877 and constituted by a grid of high density polyethylene, biplanar , having a thickness of 4.5 mm and meshes of 8 mm per side, with an intermediate layer made of polypropylene having a thickness of 1.3 mm.

On a également réalisé un tel matériau présentant une surface antiglissante en solidarisant par flammage au matériau décrit ci-dessus une couche externe réalisée en EVA, monoplanaire, présentant une épaisseur de 1 mm et des mailles de 2 mm de côté. Such a material has also been produced having a non-slip surface by joining, by flame treatment, to the material described above, an outer layer made of EVA, monoplanar, having a thickness of 1 mm and meshes of 2 mm per side.

Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier, il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter différentes variantes et modifications sans pour autant sortir ni de son cadre ni de son esprit.  Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it can be made different variants and modifications without departing from its scope or of his mind.
