Abstract
Description
La présente invention concerne une plaque de revêtement destinée à protéger des supports dont les matériaux de construction sont a priori incompatibles avec la composition du revêtement devant être utilisé ainsi qu'un procédé de fabrication d'un revêtement multicouches.The present invention relates to a coating plate intended to protect supports whose construction materials are a priori incompatible with the composition of the coating to be used as well as a method of manufacturing a multilayer coating.
De nombreuses constructions existantes ou non doivent être protégées par un revêtement qui non seulement limitera l'usure et la dégradation de la construction, mais pourra également dans certains cas avoir une fonction particulière. Ainsi, dans le domaine des cuves alimentaires, notamment celles utilisées pour le stockage du vin, il est indispensable de revêtir les parois internes des cuves en béton d'un matériau spécifique, généralement une résine thermodurcissable telle qu'une résine époxy, qui résistera aux chocs thermiques sans altérer les qualités organoleptiques du produit stocké et présentera des propriétés de résistance mécanique et de densité telles qu'il permettra d'éviter toute fissuration. Or, il est bien connu que les résines époxy par exemple adhérent très mal sur des surfaces en béton. C'est pourquoi, actuellement, pour équiper les cuves d'un tel revêtement, il est nécessaire de leur faire subir au préalable des traitements de surface fastidieux et coûteux qui, de plus, exigent le transfert sur le site d'un matériel spécifique pour réaliser ces opérations.Many existing and non-existing constructions must be protected by a coating which will not only limit the wear and degradation of the construction, but may also in certain cases have a particular function. Thus, in the field of food tanks, in particular those used for wine storage, it is essential to coat the internal walls of the concrete tanks with a specific material, generally a thermosetting resin such as an epoxy resin, which will resist thermal shock without altering the organoleptic qualities of the stored product and will have mechanical strength and density properties such that it will prevent any cracking. However, it is well known that epoxy resins, for example, adhere very poorly to concrete surfaces. This is why, currently, to equip the tanks with such a coating, it is necessary to subject them beforehand to tedious surface treatments and expensive which, moreover, require the transfer to the site of specific equipment to carry out these operations.
De même, dans le domaine du traitement des sols, on désire parfois revêtir les sols en ciment d'un matériau souple tel que du caoutchouc afin que le sol puisse par la suite absorber les chocs et les vibrations. Toutefois, ces traitements ne peuvent être réalisés que si le caoutchouc est parfaitement compatible avec les constituants du sol à revêtir pour obtenir une parfaite cohésion entre les différentes couches. Cette technique nécessitera souvent, là encore, un traitement de surface long et fastidieux afin de rendre l'ensemble des constituants parfaitement compatibles sans risquer de voir apparaître rapidement des problèmes de décollement ou de désolidarisation.Similarly, in the field of soil treatment, it is sometimes desired to coat the cement floors with a flexible material such as rubber so that the soil can subsequently absorb shocks and vibrations. However, these treatments can only be carried out if the rubber is perfectly compatible with the constituents of the soil to be coated in order to obtain perfect cohesion between the different layers. Again, this technique will often require a long and tedious surface treatment in order to make all of the constituents perfectly compatible without risking problems of detachment or separation quickly appearing.
Le but de la présente invention est donc de proposer des plaques de revêtement susceptibles d'adhérer à n'importe quelle surface, que les constituants de la surface à revêtir soient à l'origine compatibles ou non avec le constituant du revêtement devant être utilisé.The object of the present invention is therefore to propose coating plates capable of adhering to any surface, whether the constituents of the surface to be coated are originally compatible or not with the constituent of the coating to be used.
Un autre but de la présente invention est de proposer un procédé de fabrication de revêtements de forme et de dimension quelconques et dont les caractéristiques d'adhérence leur permettent d'être posés à la manière d'un carrelage sans nécessiter de traitement préalable de la surface à revêtir.Another object of the present invention is to provide a method of manufacturing coatings of any shape and size and whose adhesion characteristics allow them to be laid in the manner of a tiling without requiring prior treatment of the surface. to be coated.
La présente invention concerne à cet effet une plaque de revêtement, notamment pour des supports aux matériaux de construction non compatibles avec ledit revêtement, caractérisée en ce qu'elle comporte au moins trois couches superposées, la couche intermédiaire étant constituée de matières minérales ou synthétiques ou textiles se présentant sous forme de grains ou de fibres.The present invention relates for this purpose to a covering plate, in particular for supports for building materials not compatible with said covering, characterized in that it comprises at least three superposed layers, the intermediate layer consisting of mineral or synthetic materials or textiles in the form of grains or fibers.
Selon une autre caractéristique de l'invention, la couche recouvrant l'une des faces de la couche intermédiaire et qui est en contact avec la surface du support à revêtir comprend au moins un constituant de composition identique ou similaire à celui de la surface à revêtir. De préférence, la couche recouvrant la couche intermédiaire et destinée à constituer la surface externe de la plaque , comprend une résine thermodurcissable et/ou une résine thermoplastique et/ou un caoutchouc naturel ou synthétique.According to another characteristic of the invention, the layer covering one of the faces of the intermediate layer and which is in contact with the surface of the support to be coated comprises at least one constituent of composition identical or similar to that of the surface to be coated. Preferably, the layer covering the intermediate layer and intended to constitute the external surface of the plate, comprises a thermosetting resin and / or a thermoplastic resin and / or a natural or synthetic rubber.
L'invention concerne également un procédé de fabrication d'un revêtement multicouches, caractérisé en ce qu'on dépose sur un support de forme quelconque comportant un agent de démoulage une première couche constitutive de la surface externe du revêtement et comportant une résine thermoplastique et/ou une résine thermodurcissable et/ou un caoutchouc synthétique ou naturel, en ce qu'on recouvre cette première couche d'une couche de matières minérales, synthétiques ou textiles à l'état de fibres ou de grains, en ce qu'on fait pénétrer partiellement cette deuxième couche par gravité ou par pression, en ce qu'on dépose une troisième couche dont l'un au moins des constituants est de composition identique ou similaire à celle du support à revêtir de manière à pouvoir être fixé aisément sur ce dernier.The invention also relates to a method for manufacturing a multilayer coating, characterized in that a first layer constituting the external surface of the coating and comprising a thermoplastic resin and / or a thermosetting resin and / or a synthetic or natural rubber, in that this first layer is covered with a layer of mineral, synthetic or textile materials in the form of fibers or grains, in that it is penetrated partially this second layer by gravity or by pressure, in that a third layer is deposited, at least one of the constituents of which is of identical or similar composition to that of the support to be coated so as to be able to be easily fixed on the latter.
D'autres caractéristiques et avantages de l'invention apparaîtront encore à la lecture de la description détaillée qui suit.Other characteristics and advantages of the invention will become apparent on reading the detailed description which follows.
La fabrication des plaques de revêtement nécessite la mise en oeuvre d'un certain nombre d'étapes dans un ordre prédéterminé. Toutes les plaques de revêtement obtenues comporteront au moins trois couches, une première couche dite couche 1 qui constituera la couche externe de la plaque qui sera disposée à l'opposé du support ou de la surface à revêtir et à protéger, une deuxième couche dite couche intermédiaire ou couche 2 qui permettra l'adhésion entre la couche 1 et la troisième couche, et une troisième couche dite couche 3 qui sera directement en contact avec la surface du support à revêtir.The manufacture of the coating plates requires the implementation of a certain number of steps in a predetermined order. All the coating plates obtained will comprise at least three layers, a first layer called layer 1 which will constitute the outer layer of the plate which will be disposed opposite the support or the surface to be coated and to be protected, a second layer called layer intermediate or layer 2 which will allow adhesion between layer 1 and the third layer, and a third layer called layer 3 which will be directly in contact with the surface of the support to be coated.
La première étape de la fabrication d'une plaque de revêtement consiste à préparer un support sur lequel seront superposées les trois couches constituant la plaque de revêtement. Ce support peut être plan ou courbe. Il sera toujours en contact avec la couche 1 de la plaque de revêtement. Ce support comportera un agent de démoulage qui pourra être intégré au support ou être simplement déposé à la surface du support par enduction ou par tout autre moyen. L'agent de démoulage utilisé peut être par exemple constitué par une cire oléfinique, une laque vinylique, ou un film de polyester ou un film cellulosique, ou toute autre substance appropriée, pour permettre un démoulage rapide et aisé du constituant utilisé dans la composition de la couche externe de la plaque de revêtement. La forme du support déterminera la forme des plaques de revêtement. Ainsi, si on désire fabriquer des plaques de revêtement destinées à être apposées sur des surfaces planes, on utilisera un support plan. Au contraire, si ces plaques de revêtement sont destinées à des produits à profil courbe, le support pourra être choisi courbe. Bien évidemment, il sera possible d'apposer les plaques de revêtement planes sur n'importe quelle surface en les découpant et en les posant à la manière d'un carrelage, les joints étant réalisés à partir d'un constituant dont la composition est généralement identique à celle de la couche 1 de la plaque de revêtement.The first step in manufacturing a coating plate consists in preparing a support on which the three layers constituting the coating plate will be superimposed. This support can be flat or curved. It will always be in contact with layer 1 of the cover plate. This support will include a release agent which can be integrated into the support or simply deposited on the surface of the support by coating or by any other means. The release agent used can be, for example, constituted by an olefinic wax, a vinyl lacquer, or a polyester film or a cellulosic film, or any other suitable substance, to allow rapid and easy release of the constituent used in the composition of the outer layer of the cover plate. The shape of the support will determine the shape of the covering plates. Thus, if it is desired to manufacture covering plates intended to be affixed to flat surfaces, a flat support will be used. On the contrary, if these covering plates are intended for products with a curved profile, the support may be chosen curved. Obviously, it will be possible to affix the flat covering plates on any surface by cutting them out and laying them in the manner of a tiling, the joints being made from a constituent whose composition is generally identical to that of layer 1 of the covering plate.
Lorsque le support est prêt à recevoir la couche 1, celle-ci est déposée soit manuellement soit par projection. Dans le cas d'une résine thermodurcissable telle qu'une résine époxy, ou polyester, on utilise généralement une machine qui réalise juste avant la projection le mélange des constituants de la résine et leur chauffage afin d'assurer la polymérisation de la résine après un temps t qui aura permis le dépôt de la couche 2. Dans le cas où la couche 1 est constituée par une résine thermoplastique telle qu'une résine vinylique ou acrylique par exemple, la résine subit un traitement thermique qui entraîne sa fluidisation ou son ramollissement de telle sorte que les constituants de la couche 2 pourront par la suite partiellement pénétrer dans la couche 1. Enfin dans le cas où la couche 1 est en caoutchouc naturel ou synthétique, la surface de la couche 1 opposée à celle qui est en contact avec le support comportant l'agent de démoulage, subit un traitement chimique ou mécanique tel qu'un sablage ou un ponçage puis est ensuite enduite d'une couche de colle compatible avec le caoutchouc avant le dépôt de la couche 2.When the support is ready to receive layer 1, it is deposited either manually or by projection. In the case of a thermosetting resin such as an epoxy resin, or polyester, a machine is generally used which performs just before spraying the mixture of the constituents of the resin and their heating in order to ensure the polymerization of the resin after a time t which will have allowed the deposition of the layer 2. In the case where the layer 1 is constituted by a thermoplastic resin such as a vinyl or acrylic resin for example, the resin undergoes a heat treatment which results in its fluidization or its softening so that the constituents of layer 2 can by continued partially penetrate into layer 1. Finally, in the case where layer 1 is made of natural or synthetic rubber, the surface of layer 1 opposite to that which is in contact with the support comprising the release agent, undergoes a chemical treatment. or mechanical such as sanding or sanding and is then coated with a layer of adhesive compatible with rubber before the deposition of layer 2.
Toutes les préparations subies par la face de la couche 1 opposée à celle en contact avec le support comportant l'agent de démoulage ont pour objet de faciliter la pénétration partielle dans la couche 1 des constituants de la couche 2 qui vont constituer les agents de cohésion entre la couche 1 et la couche 3 qui présentent des compositions incompatibles ne permettant pas un accolement direct.All the preparations undergone by the face of layer 1 opposite to that in contact with the support comprising the release agent are intended to facilitate the partial penetration into layer 1 of the constituents of layer 2 which will constitute the cohesion agents between layer 1 and layer 3 which have incompatible compositions which do not allow direct joining.
Lorsque la couche 1 a été déposée et a subi les traitements préalables nécessaires, la couche 2 est déposée. Cette couche 2 peut être constituée de grains de matières minérales ou synthétiques de préférence à angle aigu tels que des grains de silice, de corindon, de grès ou similaire. Elle peut également de la même manière être constituée de matières minérales ou synthétiques ou textiles se présentant sous forme de fibres. Ces fibres peuvent être de dimension quelconque. Dans le cas où ces fibres sont non tissées, elles peuvent être projetées au moyen d'un pistolet ou déposées à l'aide d'un pinceau. Mais, ces fibres peuvent également se présenter sous la forme d'une nappe, d'un mat ou d'un rowing. Les fibres généralement utilisées sont des fibres de verre. Une fois que ces fibres ou grains ont été déposés, il convient de les faire pénétrer partiellement dans la couche 1. Cette pénétration peut se faire uniquement par gravité dans le cas où la couche 2 présente une densité supérieure à la couche 1 ou par pression notamment au moyen d'un rouleau dans le cas de charges fibreuses.When layer 1 has been deposited and has undergone the necessary preliminary treatments, layer 2 is deposited. This layer 2 may consist of grains of mineral or synthetic materials, preferably at an acute angle, such as grains of silica, corundum, sandstone or the like. It can also in the same way consist of mineral or synthetic or textile materials in the form of fibers. These fibers can be of any size. In the case where these fibers are nonwoven, they can be projected by means of a gun or deposited using a brush. However, these fibers can also be in the form of a sheet, a mat or a rowing. The fibers generally used are glass fibers. Once these fibers or grains have been deposited, they should be partially penetrated into layer 1. This penetration can be done only by gravity in the case where layer 2 has a density greater than layer 1 or by pressure in particular. by means of a roller in the case of fibrous fillers.
Lorsque la couche 2 est étalée et qu'une partie des constituants de cette couche a pénétré dans la couche 1, la couche 1 se durcit quelle que soit sa composition de manière à emprisonner les constituants de la couche 2.When layer 2 is spread and part of the constituents of this layer have penetrated into layer 1, the layer 1 hardens whatever its composition so as to trap the constituents of layer 2.
A ce moment, la couche 3 peut alors être déposée. Sa composition peut être très variée et sera fonction de la compostion de la surface à revêtir. Ainsi, dans le cas où l'on désire revêtir un support en béton, on utilisera comme constituant principal de la couche 3 un ciment. Il sera très facile par la suite de fixer la couche 3 au support puisque les constituants seront parfaitement compatibles sans faire subir au support de traitement de surface spécifique. Ce montage ne nécessitera pas d'appareillage approprié et pourra être réalisé sans qualification particulière. La couche 3 pourra outre son constituant compatible avec le support comporter également des renforts tels que des fibres de verre ou une armature métallique ou tout autre moyen permettant d'augmenter la résistance mécanique de la couche 3. Ces renforts pourront également, dans certains cas, par exemple dans le cas d'une armature métallique, être utilisés pour faciliter la liaison avec le support à revêtir. De même, ces éléments de renfort peuvent permettre la constitution de panneaux de construction , de panneaux de construction préfabriqués, d'éléments de coffrage, etc. L'aspect de la face de la couche 3 en contact avec le support pourra être quelconque en fonction des buts recherchés. Ainsi, cette face pourra être rugueuse ou granulaire ou fibreuse ou lisse ou autre.At this time, layer 3 can then be deposited. Its composition can be very varied and will depend on the composition of the surface to be coated. Thus, in the case where it is desired to coat a concrete support, a cement will be used as the main constituent of layer 3. It will then be very easy to attach layer 3 to the support since the constituents will be perfectly compatible without subjecting the support to specific surface treatment. This assembly will not require appropriate equipment and can be carried out without any particular qualification. The layer 3 may, in addition to its constituent compatible with the support, also include reinforcements such as glass fibers or a metal frame or any other means making it possible to increase the mechanical resistance of the layer 3. These reinforcements may also, in certain cases, for example in the case of a metal frame, be used to facilitate the connection with the support to be coated. Likewise, these reinforcing elements can allow the construction of construction panels, prefabricated construction panels, formwork elements, etc. The appearance of the face of the layer 3 in contact with the support may be arbitrary depending on the goals sought. Thus, this face may be rough or granular or fibrous or smooth or other.
Grâce à ces plaques de revêtement obtenues à partir de la superposition des couches 1, 2 et 3, le revêtement de support est quasi-immédiat quelle que soit la composition de la surface à revêtir et ne nécessite pas d'appareillage particulier. De plus, comme la pose de ces plaques s'effectue de manière similaire à un carrelage et que ces plaques peuvent avoir des dimensions quelconques, on limite le nombre de joints. De plus, ces joints pourront être réalisés en un matériau compatible avec la matière à stocker puisqu'ils seront d'une composition analogue à celle de la couche 1, ce qui n'était pas le cas dans la technique antérieure bien que cela présente de nombreux avantages notamment dans le cas de stockages de produits alimentaires.Thanks to these coating plates obtained from the superposition of layers 1, 2 and 3, the support coating is almost immediate whatever the composition of the surface to be coated and does not require any particular apparatus. In addition, as the laying of these plates is carried out in a similar manner to a tiling and that these plates can have any dimensions, the number of joints is limited. In addition, these joints may be made of a material compatible with the material to be stored since they will be of a composition similar to that of layer 1, this which was not the case in the prior art, although this has many advantages, particularly in the case of storage of food products.
