Description

La présente invention concerne un nouveau type de matériau à base d'une nappe textile non tissée utilisable comme armature de renforcement de revêtements d'étanchéité constitués d'un support noyé dans une composition de bitume.The present invention relates to a new type of material based on a nonwoven textile web usable as reinforcement for waterproofing coatings consisting of a support embedded in a bitumen composition.

De tels revêtements d'étanchéité à base de bitume renforcés par une structure textile sont connus depuis fort longtemps.Such bitumen-based waterproofing coatings reinforced by a textile structure have been known for a very long time.

Le plus ancien est celui qui avait été utilisé par Noé pour construire son arche.The oldest is the one that Noah had used to build his ark.

En effet, ainsi que cela ressort clairement de l'Ancien Testament, Genèse-Verset 14, avant le déluge Yahvé dit à Noé : "Fais-toi une arche en bois résineux, tu la feras en roseaux et tu l'enduiras de bitume en-. dedan6 et en-dehors".Indeed, as is clear from the Old Testament, Genesis-Verse 14, before the flood Yahweh said to Noah: "Make yourself an ark of coniferous wood, you will make it out of reeds and you will coat it with bitumen in - inside and outside ".

Ainsi, il ressort clairement de cette description que des matériaux étanches à base de bitume renforcé par une structure servant de support étaient connus.Thus, it is clear from this description that waterproof materials based on bitumen reinforced by a structure serving as support were known.

Depuis cette époque, de tels matériaux n'ont cessé d'être utilisés, notamment pour réaliser la couverture de bâtiments. Les armatures de renforcement ont bien évidemment évolué en même temps que de nouvelles matières textiles et/ou structures à base de ces matières apparaissaient sur le marché.Since that time, such materials have not ceased to be used, especially for the roofing of buildings. Reinforcement reinforcements have obviously evolved at the same time as new textile materials and / or structures based on these materials appeared on the market.

Ainsi, il a été proposé d'utiliser comme armatures de renforcement des films chimiques, des tissus, des non- tissés, à base de matières synthétiques ou minérales (verre par exemple).Thus, it has been proposed to use as reinforcements for reinforcing chemical films, fabrics, nonwovens, based on synthetic or mineral materials (glass for example).

Il a aussi été envisagé d'utiliser des feutres à base de fibres de verre, des structures tissées ou non (FR-A-1 330 291, 1 491 454), voire même de réaliser des complexes non tissés/tissus dans lesquels les différentes - 2 - couches sont liées entre elles par des coutures (US-A-3 044 146) et/ou d'associer des nappes à base de matière textile différente par exemple un non-tissé polyester et un voile de fibres de verre.It has also been envisaged to use felts based on glass fibers, woven or non-woven structures (FR-A-1 330 291, 1 491 454), or even to produce non-woven / fabric complexes in which the various - 2 - layers are linked together by seams (US-A-3,044,146) and / or combine tablecloths based on different textile material, for example a polyester nonwoven and a veil of glass fibers.

Toutes les propositions faites à ce jour ne permettent cependant pas d'obtenir de manière économique, à grande vitesse, un complexe fibreux qui soit facile à manipuler et à stocker et qui présente l'ensemble des qualités exigées lorsque l'on désire réaliser un revêtement d'étanchéité monocouche à savoir de très bonnes propriétés mécaniques, une stabilité dimensionnelle et une excellente résistance aux poinçonnements tant statique que dynamique.However, all the proposals made to date do not make it possible to economically obtain, at high speed, a fibrous complex which is easy to handle and store and which has all the qualities required when it is desired to make a coating. single-layer waterproofing, namely very good mechanical properties, dimensional stability and excellent resistance to punctures, both static and dynamic.

Le matériau le plus approprié pour remplir toutes ces caractéristiques est, à ce jour, constitué par un complexe formé d'un non-tissé en polyester associé sur l'une de ses faces avec une grille textile en verre.The material most suitable for fulfilling all these characteristics is, to date, constituted by a complex formed of a polyester nonwoven associated on one of its faces with a glass textile grid.

Un tel complexe est commercialisé par le Demandeur sous la référence 603 GP 70.Such a complex is marketed by the Applicant under the reference 603 GP 70.

Il donne de très bons résultats mais nécessite des' installations complexes pour le réaliser.It gives very good results but requires' complex installations to achieve it.

Or on a trouvé, et c'est ce qui fait l'objet de-la présente invention, un nouveau type de complexe fibreux qui, non seulement permet d'obtenir les caractéristiques souhaitées pour des revêtements d'étanchéité à base de bitume et plus particulièrement les revêtements monocouche mais qui, par ailleurs, peut être produit à grande vitesse, est facile à stocker et manipuler, présente une très grande stabilité dimensionnelle et une excellente résistance aux poinçonnements, tant dynamique que statique.Now we have found, and this is what is the subject of the present invention, a new type of fibrous complex which not only makes it possible to obtain the desired characteristics for bitumen-based waterproofing coatings and more particularly single layer coatings but which, moreover, can be produced at high speed, is easy to store and handle, has very high dimensional stability and excellent resistance to punctures, both dynamic and static.

D'une manière générale, l'invention concerne donc un matériau utilisable comme armature de renforcement de revêtements d'étanchéité bitumineux, ledit matériau étant du type constitué par une nappe fibreuse non tissée et étant caractérisé par le fait que ladite nappe est formée d'un complexe comportant une couche intermédiaire constituée par un non-tissé en polyester, ce non-tissé servant de support à des fibres de verre implantées dans son épaisseur, fibres qui dépassent de chaque côté dudit support et sont rabattues contre celui-ci.In general, the invention therefore relates to a material which can be used as reinforcement for the reinforcement of bituminous waterproofing coatings, said material being of the type constituted by a nonwoven fibrous sheet and being characterized in that said ply is formed of a complex comprising an intermediate layer constituted by a polyester nonwoven, this nonwoven serving as a support for glass fibers implanted in its thickness, fibers which protrude on each side of said support and are folded against it.

De préférence, la couche interne à base de polyester est un non-tissé réalisé à partir de filaments continus, relativement compact et de faible épaisseur, les fibres de verre étant quant à elles implantées dans le non-tissé par aiguilletage.Preferably, the polyester-based inner layer is a nonwoven produced from continuous filaments, relatively compact and of small thickness, the glass fibers being implanted in the nonwoven by needling.

Un tel matériau est obtenu, de manière simple, en superposant la nappe interne en polyester avec une nappe de fibres de verre, lesdites fibres de verre ayant une longueur telle que lorsque l'ensemble est soumis à une opération d'aiguilletage, elles soient implantées dans la nappe de polyester et ressortent, sur la face opposée à celle où s'exerce l'action des aiguilles, sous la forme de bouclettes.Such a material is obtained, in a simple manner, by superimposing the internal polyester ply with a ply of glass fibers, said glass fibers having a length such that when the assembly is subjected to a needling operation, they are implanted in the polyester sheet and emerge, on the face opposite to that where the action of the needles is exerted, in the form of loops.

L'ensemble ainsi réalisé est ensuite calandré et éventuellement imprégné à l'aide d'une matière collante de type connu compatible avec le bitume.The assembly thus produced is then calendered and optionally impregnated using a tacky material of known type compatible with bitumen.

L'invention et les avantages qu'elle apporte seront. cependant mieux compris grâce à l'exemple de réalisation donné ci-après à titre indicatif mais non limitatif et qui est illustré par la figure unique annexée.The invention and the advantages which it brings will be. however, better understood thanks to the exemplary embodiment given below by way of indication but not limitation and which is illustrated by the single appended figure.

On réalise un matériau conforme à l'invention sur une installation conventionnelle permettant d'associer des nappes non tissées, cette installation comportant essentiellement une aiguilleteuse à la sortie de laquelle est disposé un bac d'imprégnation, une calandre et un four de séchage.A material according to the invention is produced on a conventional installation making it possible to associate nonwoven webs, this installation essentially comprising a needling machine at the outlet of which is placed an impregnation tank, a calender and a drying oven.

Sur une telle installation, on introduit, superposées une nappe de polyester pesant 70 g/m 2 et une nappe de fibres de verre pesant 150 à.160 g/m2, lesdites fibres ayant une longueur comprise entre 100 et 150 mm.On such an installation, a layer of polyester weighing 70 g / m 2 and a layer of glass fibers weighing 150 to 160 g / m 2 are introduced, superimposed, said fibers having a length of between 100 and 150 mm.

La nappe de verre est disposée au-dessus de la nappe de polyester de telle sorte que les aiguilles de l'aiguilleteuse entraînent les fibres de verre au travers de la nappe de polyester.The glass sheet is arranged above the polyester sheet so that the needles of the needling machine entrain the glass fibers through the polyester sheet.

Conformément à l'invention, l'aiguilleteuse est réglée de telle sorte que, ainsi que cela ressort de la figure annexée, les fibres de verre (1) traversent la nappe de polyester (2) et dépassent de chaque côté de cette nappe. Après calandrage,sur l'une des faces (3) par exemple de la nappe (2), les fibres de verre (1) se présentent sous la forme de bouclettes aplaties (4) alors que, de l'autre côté, c'est-à-dire du côté par lequel pénètrent les aiguilles, lesdites fibres de verre (1) présentent deux extrémités libres (5a,5b) également aplaties contre l'autre face (6) de la nappe (2).According to the invention, the needling machine is adjusted so that, as can be seen from the appended figure, the glass fibers (1) pass through the polyester sheet (2) and protrude on each side of this sheet. After calendering, on one of the faces (3) for example of the sheet (2), the glass fibers (1) are in the form of flattened loops (4) while, on the other side, it that is to say on the side by which the needles penetrate, said glass fibers (1) have two free ends (5a, 5b) also flattened against the other face (6) of the ply (2).

Après aiguilletage, l'ensemble passe dans un bac d'imprégnation contenant une matière liante, par exemple une colle de type Styrène butadiène, puis entre deux cylindres permettant d'exprimer l'ensemble et d'aplatir les fibres de verre contre les faces de la nappe de polyester. Dans le cas présent, la colle est déposée à raison de 130 g/m 2 . After needling, the assembly passes through an impregnation tank containing a binding material, for example an adhesive of the Styrene butadiene type, then between two cylinders allowing the assembly to be expressed and the glass fibers to be flattened against the faces of the polyester tablecloth. In the present case, the adhesive is deposited at the rate of 130 g / m 2 .

Le complexe ainsi réalisé peut être stocké sous la forme d'enroulement de grande longueur pour être ensuite revêtu d'une couche de bitume permettant d'obtenir un ensemble étanche de quatre millimètres d'épaisseur.The complex thus produced can be stored in the form of a very long winding and then be coated with a layer of bitumen making it possible to obtain a sealed assembly four millimeters thick.

Cet ensemble présente d'excellentes caractéristiques de stabilité dimensionnelle et de résistance au poinçonnement statique et dynamique, le rendant particulièrement approprié pour permettre de réaliser un revêtement d'étanchéité monocouche.This assembly has excellent characteristics of dimensional stability and resistance to static and dynamic punching, making it particularly suitable for making a single-layer waterproofing coating.

De plus, le complexe textile de base peut facilement être stocké et manipulé, ce qui présente un avantage certain étant donné, qu'en général, le revêtement en bitume est réalisé par d'autres industriels que ceux fabriquant les armatures de renforcement.In addition, the basic textile complex can easily be stored and handled, which has a certain advantage given that, in general, the bitumen coating is produced by other manufacturers than those manufacturing reinforcements.

Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation décrit précédemment mais elle en couvre toutes les variantes réalisées dans le même esprit. Ainsi, si dans l'exemple de réalisation décrit précédemment, une seule nappe de verre et une seule nappe de polyester sont utilisées pour réaliser le complexe, il pourrait être envisagé d'emprisonner la nappe de polyester entre deux nappes de verre, l'ensemble subissant alors un aiguilletage sur les deux faces. De plus, d'autres éléments additionnels de renforcement tels que par exemple une grille non-tissée, un film pourraient être interposés entre les fibres de polyester et de verre.Of course, the invention is not limited to the embodiment described above, but it covers all the variants produced in the same spirit. Thus, if in the embodiment described above, a single glass sheet and a single polyester sheet are used to produce the complex, it could be envisaged to trap the polyester sheet between two glass sheets, the assembly then undergoing needling on both sides. In addition, other additional reinforcing elements such as for example a nonwoven grid, a film could be interposed between the polyester and glass fibers.
