Description

La présente invention a pour objet un matériau d'étanchéité et/ou d'insonorisation en feuille, destiné plus particulièrement à une utilisation dans des milieux agressifs, chimiques ou biologiques, et en particulier dans une ambiance soumise aux polluants atmosphériques tels qu'acides, bases, solvants et toutes émanations pouvant être de manière plus générale rejetées sur une toiture. The subject of the present invention is a sheet sealing and / or soundproofing material, intended more particularly for use in aggressive, chemical or biological environments, and in particular in an environment subject to atmospheric pollutants such as acids, bases, solvents and all fumes that can be more generally rejected on a roof.

En raison des diverses émanations gazeuses, liquides ou solides, rejetées dans l'atmosphère de manière continue ou accidentelle, on rencontre partout de gros problèmes en ce qui concerne les étanchéi-tés des toitures. Due to the various gaseous, liquid or solid fumes, discharged into the atmosphere continuously or accidentally, there are big problems everywhere with regard to roof waterproofing.

Les feuilles d'étanchéité bitumineuses simples sont fortement agressées par des rejets de solvants aromatiques ou chlorés pouvant résulter de nombreux procédés industriels, l'attaque s'opérant par dissolution progressive du bitume. Par ailleurs, les rejets oxydants (gaz sulfureux, acides divers) amènent rapidement une fragilisation du bitume et il est en conséquence nécessaire de refaire fréquemment l'étanchéité de surface. Simple bituminous waterproofing sheets are strongly attacked by releases of aromatic or chlorinated solvents which can result from numerous industrial processes, the attack taking place by progressive dissolution of the bitumen. In addition, oxidizing releases (sulfurous gases, various acids) quickly cause embrittlement of the bitumen and it is therefore necessary to frequently re-seal the surface.

Les feuilles d'étanchéité bitumineuses recouvertes d'une feuille d'aluminium sont elles aussi rapidement agressées par les émanations de gaz sulfureux' ainsi que par les émanations alcalines ou acides. Bituminous waterproofing sheets covered with aluminum foil are also quickly attacked by sulfur gas fumes as well as by alkaline or acid fumes.

On a déjà proposé des produits de protection du bitume capables d'assurer la continuité de cette protection en cas d'agression corrosive, pariexemple de l'acier inoxydable en feuille. Toutefois, l'acier inoxydable est de coût très élevé et il présente une rigidité très importante. Bitumen protection products have already been proposed capable of ensuring the continuity of this protection in the event of corrosive aggression, for example sheet stainless steel. However, stainless steel is very expensive and has very high rigidity.

On a également proposé des membranes plastiques protectrices qui sont toutefois de mise en œuvre très délicate sur un chantier. Elles comportent en outre des plastifiants qui tendent à migrer en surface et à créer une couche poisseuse accrochant les poussières. Protective plastic membranes have also been proposed, which are however very delicate to use on a site. They also contain plasticizers which tend to migrate to the surface and create a tacky layer which attaches the dust.

La présente invention a pour objet de pallier les divers inconvénients des membranes connues. The object of the present invention is to overcome the various drawbacks of known membranes.

Ce résultat est obtenu, conformément à l'invention, en proposant une membrane composite souple d'étanchéité et/ou d'insonorisation, du type comprenant une sous-couche bitumineuse recouverte d'une couche protectrice résistant aux intempéries et aux divers polluants atmosphériques, chimiques ou biologiques, caractérisée en ce que la couche protectrice comprend essentiellement une feuille continue d'une matière synthétique préalablement stabilisée au regard de toute rétraction possible. This result is obtained, in accordance with the invention, by proposing a flexible composite waterproofing and / or soundproofing membrane, of the type comprising a bituminous undercoat covered with a protective layer resistant to weathering and various atmospheric pollutants, chemical or biological, characterized in that the protective layer essentially comprises a continuous sheet of a synthetic material previously stabilized with regard to any possible retraction.

On a en effet été conduit à penser que l'association d'une feuille plastique, exempte de plastifiants et résistant aux agents agressifs, et d'une feuille d'étanchéité bitumineuse permettrait de réaliser un complexe parfaitement résistant aux diverses agressions extérieures, tout en restant applicable en toiture selon les moyens de mise en œuvre traditionnels en la matière. We have indeed been led to think that the combination of a plastic sheet, free of plasticizers and resistant to aggressive agents, and a bituminous sealing sheet would make it possible to produce a complex which is perfectly resistant to various external aggressions, while remaining applicable to roofing according to the traditional means of implementation in the matter.

Cependant, les feuilles plastiques subissent, en cours de fabrication de la feuille d'étanchéité, un choc thermique et tendent en conséquence à se rétracter considérablement lors de leur mise en œuvre, par un phénomène de reptation. Il s'ensuit des discontinuités dans la couche de protection et des risques de tension en bout des lés posés. However, the plastic sheets undergo, during the manufacture of the sealing sheet, a thermal shock and consequently tend to shrink considerably during their implementation, by a phenomenon of crawling. This results in discontinuities in the protective layer and the risk of tension at the end of the strips laid.

Conformément à l'invention, telle que définie ci-dessus, la feuille plastique doit donc être stabilisée vis-à-vis de cette rétractation prenant naissance lors de la mise en œuvre. In accordance with the invention, as defined above, the plastic sheet must therefore be stabilized with respect to this retraction which arises during implementation.

On pourrait envisager de stabiliser la feuille plastique par contre-collage sur un support rigide, tel que par exemple un mat de verre ou un feutre d'amiante. One could consider stabilizing the plastic sheet by lamination on a rigid support, such as for example a glass mat or an asbestos felt.

Cependant, il y a des risques d'incompatibilité entre la sous-couche bitumineuse et la colle utilisée pour cette opération. D'autre part, on risque la présence d'occlusion d'air sous la feuille plastique, ce qui peut entraîner des cloques ou des pustules. However, there are risks of incompatibility between the bituminous underlay and the glue used for this operation. On the other hand, there is a risk of the occlusion of air under the plastic sheet, which can cause blisters or pustules.

Conformément à une forme d'exécution de l'invention, la feuille plastique sera contrecollée à l'aide d'une colle réactive sur un support continu, ladite colle réactive devant être bien entendu parfaitement compatible avec les deux éléments du contrecollage, à savoir le film plastique et son support. Le support continu évite le contact direct entre la colle et le bitume, et donc les phénomènes d'incompatibilité précités. According to one embodiment of the invention, the plastic sheet will be laminated using a reactive adhesive on a continuous support, said reactive adhesive must of course be perfectly compatible with the two elements of the laminating, namely the plastic film and its support. The continuous support avoids direct contact between the adhesive and the bitumen, and therefore the aforementioned incompatibility phenomena.

De manière préférentielle et avantageuse, le support de contre-collage sera constitué d'une feuille métallique, de préférence de l'aluminium et aura une épaisseur pouvant varier, par exemple et non li-mitativement, de 9 à 200 (i, plus particulièrement de 20 à 80 p.. Preferably and advantageously, the lamination support will consist of a metal sheet, preferably aluminum and will have a thickness which can vary, for example and not li-mitatively, from 9 to 200 (i, more particularly from 20 to 80 p ..

Un procédé pour le contrecollage de la feuille plastique sur son support peut être par exemple le suivant: A method for laminating the plastic sheet on its support can be for example the following:

- enduction du support par une colle réactive solvantée; - coating of the support with a reactive solvent-based adhesive;

- évaporation du solvant dans un four; - evaporation of the solvent in an oven;

- application du film plastique par calandrage à température ambiante afin d'éviter que celui-ci ne se déforme, la liaison obtenue étant supérieure à la cohésion propre des feuilles plastiques. - Application of the plastic film by calendering at room temperature in order to prevent it from deforming, the bond obtained being greater than the inherent cohesion of the plastic sheets.

On pourra utiliser tous les films synthétiques thermoplastiques, élastomères, pour cette application, pour autant qu'ils répondent aux exigences de protection vis-à-vis des agressions atmosphériques. De manière avantageuse, on utilisera un film polyfluorure de vinyle de faible épaisseur, par exemple comprise entre 10 et 100 (t. All thermoplastic, elastomeric synthetic films may be used for this application, provided that they meet the requirements for protection against atmospheric attack. Advantageously, a thin polyfluoride vinyl film will be used, for example between 10 and 100 (t.

Avantageusement le film aura une épaisseur optimale de 37,5 |x. Il devra être déformable, résistant aux agressions atmosphériques et chimiquement inerte, pigmenté dans la masse sans plastifiants. Advantageously, the film will have an optimal thickness of 37.5 | x. It must be deformable, resistant to atmospheric attack and chemically inert, pigmented in the mass without plasticizers.

En raison des techniques traditionnelles propres au domaine de l'étanchéité, le complexe ainsi formé est gaufré ou embouti afin de réduire les zones de dilatation et de contraction à des parties élémentaires avant d'être enduit de bitume, armé ou non, par les méthodes habituelles de fabrication des chapes bitumineuses. Due to traditional techniques specific to the waterproofing field, the complex thus formed is embossed or stamped in order to reduce the zones of expansion and contraction to elementary parts before being coated with bitumen, reinforced or not, by the methods usual manufacturing of bituminous screeds.

On a pu vérifier expérimentalement la stabilité du complexe sur une chape ainsi réalisée en soumettant celui-ci à un cycle thermique donné, montrant que, après ces diverses phases, il n'y a ni allongement ni contraction du complexe. We were able to verify experimentally the stability of the complex on a screed thus produced by subjecting it to a given thermal cycle, showing that, after these various phases, there is neither elongation nor contraction of the complex.

L'ensemble ainsi réalisé peut être collé à bain de bitume sur tout support apte à recevoir une étanchéité et apprêté selon les méthodes traditionnelles. The assembly thus produced can be bonded in a bitumen bath on any support capable of receiving a seal and primed according to traditional methods.

Dans la pratique, on ménagera une zone non recouverte par le complexe film-support sur un bord de chaque lé, qui servira au re- 5 couvrement latéral par le lé adjacent et ainsi de suite. In practice, an area not covered by the film-support complex will be provided on one edge of each strip, which will be used for lateral covering by the adjacent strip and so on.

Pour éviter que le bitume de collage ne vienne polluer le complexe des lés adjacents, ces derniers seront avantageusement enduits d'eau savonneuse, jusqu'à la limite du collage, le bitume ayant débordé pouvant alors être décollé du film plastique sans détériorer 10 celui-ci. Les chants en bout de lés seront protégés soit par une peinture résistant aux agressions chimiques, de type polyuréthanne par exemple, soit par des bandes auto-adhésives du complexe décrit ci-dessus, ou encore par tout autre moyen approprié. To prevent the bonding bitumen from polluting the complex of adjacent strips, the latter will advantageously be coated with soapy water, up to the limit of sticking, the bitumen having overflowed then being able to be detached from the plastic film without damaging it. this. The edges at the end of the strips will be protected either by a paint resistant to chemical attack, of the polyurethane type for example, or by self-adhesive tapes of the complex described above, or by any other suitable means.

On réalise ainsi une chape d'étanchéité réalisant les divers avan- 15 tages suivants: A sealing yoke is thus produced which achieves the following various advantages:

- le bitume d'étanchéité est protégé contre les diverses agressions atmosphériques; - the waterproofing bitumen is protected against various atmospheric attacks;

- la protection est à la fois durable et esthétique, s'intégrant à l'architecture du bâtiment et du site ; 20 - the protection is both durable and aesthetic, integrating with the architecture of the building and the site; 20

- la mise en œuvre est aisée et il n'y a pas de risques de déchirures ou de chocs poinçonnants; - the implementation is easy and there is no risk of tears or puncturing shocks;

- le complexe peut s'adapter à toutes les variations dimension-nelles de la structure porteuse; - the complex can adapt to all dimensional variations of the supporting structure;

- la surface externe est nettoyable, et même quasiment autonet- 25 toyante sous la seule action des eaux de pluie, et the external surface is cleanable, and even almost self-cleaning under the sole action of rainwater, and

- l'ensemble est résistant au feu en raison de la couche-support métallique, mais on peut en outre, si on le désire, utiliser un film plastique ignifuge. - the assembly is fire-resistant due to the metallic support layer, but it is also possible, if desired, to use a flame-retardant plastic film.

L'ensemble du produit comportant la sous-couche bitumineuse et le complexe support-film peut être enduit sur sa face inférieure de produit adhésif en couche mince ou épaisse, pouvant varier de quelques microns à quelques millimètres, avec ou sans armature, ce qui permet son emploi dans des zones où, lors de la mise en œuvre, une flamme pourrait dégrader le film plastique, ou encore lorsque l'on ne peut travailler avec les techniques habituelles du bitume fondu. The entire product comprising the bituminous undercoat and the support-film complex can be coated on its underside with adhesive product in a thin or thick layer, which can vary from a few microns to a few millimeters, with or without reinforcement, which allows its use in areas where, during processing, a flame could degrade the plastic film, or even when it is not possible to work with the usual techniques of molten bitumen.

Pour ce type d'applications, le produit adhésif sera protégé à l'aide d'un complexe papier/polyéthylène crêpé siliconé à retirer lors de la mise en œuvre. For this type of application, the adhesive product will be protected using a silicone crepe paper / polyethylene complex to be removed during processing.

Le gaufrage apportant une capacité d'allongement sans tension importante, le produit pourra servir au pontage des fissures, à l'habillage des cheminées, noues, solives ou autres émergences, et à réaliser une étanchéité de couverture esthétique sans peinture ni enduit. The embossing brings an elongation capacity without significant tension, the product can be used for bridging cracks, for dressing chimneys, valleys, joists or other emergencies, and for sealing an aesthetic cover without painting or coating.

En outre, le produit selon l'invention peut également être utilisé comme plaque d'insonorisation dans des éléments de machines ou de constructions soumis à des atmosphères agressives. In addition, the product according to the invention can also be used as a soundproofing plate in machine or construction elements subjected to aggressive atmospheres.

Enfin, on ne sortira pas du cadre de l'invention en réalisant le complexe du film plastique et de son support par des techniques équivalant au contrecollage. Ainsi, ce complexe pourra être réalisé par extrusion, enduction de plastisols ou autre projection avant polymérisation sur le support métallique, l'épaisseur du film obtenu pouvant varier entre 1 et 500 |i. Finally, it will not depart from the scope of the invention to produce the complex of the plastic film and of its support by techniques equivalent to laminating. Thus, this complex can be produced by extrusion, coating with plastisols or other projection before polymerization on the metal support, the thickness of the film obtained possibly varying between 1 and 500 | i.
