Abstract
Description
Revêtement à base de résine #tratifiée et à deux modes d'armatures. Coating based on # tratified resin and two modes of reinforcement.
La présente invention concerne un revêtement à base de résine stratifiée et à deux modes d'armature, pouvant s'appliquer sur divers types de supports utilisés aussi bien dans le domaine de l'industrie que dans le domaine du bâtiment. The present invention relates to a coating based on laminated resin and with two modes of reinforcement, which can be applied to various types of supports used both in the industrial field and in the building field.
Elle a plus particulièrement pour objet un revetement facile d'emploi, qui présente deexcellentes propriétés en ce qui concerne notamment l'étanchéité, la résistance à la corrosion, à l'électrocorrosion, aux agressions chimiques, ainsi qu'une très bonne résistance au feu. It relates more particularly to an easy-to-use coating, which has excellent properties with regard in particular to sealing, resistance to corrosion, to electrocorrosion, to chemical attack, as well as very good fire resistance. .
D'une manière générale, on sait que l'on réalise déjà, pour de nombreuses applications, des revetements composés de résines stratifiées telles que du polyester armé de fibres de verre. Dans ces reve - tements, la fibre de verre qui se présente généralement sous frime d'un mât de laine de verre, se trouve enrobée, par pultrusion, dans la résine. In general, it is known that, for many applications, coatings composed of laminated resins such as polyester reinforced with glass fibers are already produced. In these coatings, the fiberglass, which generally appears under the frost of a glass wool mast, is coated, by pultrusion, in the resin.
Toutefois, en raison de la disposition, le plus souvent aléatoire, des fibres de verre, et de défauts d'imprégnation, on constate que ces revetements ne sont pas parfaitement étanches. En outre, on ne parvient généralement pas à obtenir directement un état de surface satisfaisant. C'est la raison pour laquelle on utilise habituellement une couche de gel coat qui permet d' assurer, à la fois, l'étanchéité et l'état de surface. Cette solution ne s' avère pas, elle non plus, entièrement satisfaisante, en raison des défauts de résistance mécanique et à la corrosion du gel coat, de sorte qu' à la longue, le problème relatif à l'étanchéité ressurgit. However, because of the arrangement, most often random, of the glass fibers, and of impregnation defects, it can be seen that these coatings are not perfectly waterproof. In addition, it is generally not possible to directly obtain a satisfactory surface condition. This is the reason why a layer of gel coat is usually used, which makes it possible to ensure both sealing and the surface condition. This solution does not turn out to be entirely satisfactory either, because of the mechanical strength and corrosion resistance of the gel coat, so that in the long run, the problem relating to the sealing reappears.
L'invention a donc pour but de supprimer tous ces inconvénients. Elle propose, à cet effet, un revêtement composé d'un substrat constitué par une couche de résine stratifiée telle que, par exemple, de polyester, de résine époxy, de polyuréthane, etc.... The invention therefore aims to eliminate all these drawbacks. To this end, it proposes a coating composed of a substrate constituted by a layer of laminated resin such as, for example, polyester, epoxy resin, polyurethane, etc.
armée de fibres de verre et d' au moins une couche de couverture en résine stratifiée de même nature que celle du substrat, mais armée de fines écailles de verre.reinforced with glass fibers and at least one covering layer of laminated resin of the same kind as that of the substrate, but reinforced with fine glass scales.
Ces écailles de verre peuvent avantageusement présenter une épaisseur de l'ordre de quelques microns, par exemple de 3 à 4 p et un diamètre de l'ordre de quelques millimètres, par exemple de 2 à 6 mm. A l'intérieur de la couche de couverture, ces écailles sont enrobées dans la résine et imbriquées les unes sur les autres tout en restant sensiblement parallèles entre elles et à la couche de couverture. Elles se trouvent donc séparées les unes des autres par un mince film de résine.De même, en raison de cette disposition, au niveau des deux faces de la couche de couvertllre, la résine forme un film continu qui n'est en aucune fagon traversé par les écailles de verre, contrairement à ce qui se produirait si l'on utilisait de la fibre de verre orientée aléatoirement. These glass flakes can advantageously have a thickness of the order of a few microns, for example from 3 to 4 μm and a diameter of the order of a few millimeters, for example from 2 to 6 mm. Inside the cover layer, these scales are coated in the resin and overlapping one another while remaining substantially parallel to each other and to the cover layer. They are therefore separated from each other by a thin film of resin. Similarly, because of this arrangement, at the two faces of the cover layer, the resin forms a continuous film which is in no way crossed by glass flakes, unlike what would happen if we used randomly oriented fiberglass.
Ainsi, on obtient une couche de couverture présentant un très bon état de surface sans avoir à utiliser un gel coat. Thus, one obtains a covering layer having a very good surface condition without having to use a gel coat.
Par ailleurs, l'étanchéité de cette couche de couverture s'avère excellente, d'une part, en raison de la continuité du film superficiel et, d'autre part, du fait que chacun des films de résine s'étendant entre deux écailles respectives constitue en lui-même une barrière d'étanchéité. Il ne peut donc pas se produire de défauts d'étanchéité, du type de ceux constatés dans les couches de résine armée de fibres de verre, dans lesquelles l'eau peut se propager, par capillarité, le long des fibres de verre et traverser ainsi la couche. Dans le cas de la couche de couvertl3re selon l'invention, chaque écaille de verre se trouve enfermée dans un volume fermé de résine.Ainsi, dans le cas où, pour une raison quelconque, l'eau atteindrait une écaille, un phénomène de capillarité pourrait se produire autour de l'écaille, mais ne pourrait absolument pas se propager aux écailles avoisinantes. La couche de couverture demeurerait donc étanche. Furthermore, the sealing of this covering layer proves to be excellent, on the one hand, because of the continuity of the surface film and, on the other hand, because each of the resin films extending between two scales in themselves constitutes a sealing barrier. It is therefore not possible to produce leaks, of the type found in layers of resin reinforced with glass fibers, in which water can propagate, by capillary action, along the glass fibers and thus pass through. layer. In the case of the cover layer according to the invention, each glass flake is enclosed in a closed volume of resin. Thus, if, for whatever reason, the water reaches a flake, a phenomenon of capillarity could occur around the scale, but absolutely could not spread to the neighboring scales. The cover layer would therefore remain waterproof.
Une des caractéristiques particulièrement avantageuse du revêtement selon l'invention consiste en ce-qu'il combine les avantages de la couche de couverture précédemment décrite à ceux du substrat en résine armée de fibres de verre. One of the particularly advantageous characteristics of the coating according to the invention consists in that it combines the advantages of the covering layer previously described with those of the resin substrate reinforced with glass fibers.
Cette combinaison permet notamment d' augmenter considérablement la résistance mécanique du revebement. Celui-ci peut, dès lors, subir des déformations et/ou des contraintes, notamment en cisaillement, sans qu'il se produise de ruptures nuisibles de la couche de couverture pouvant-entraîner des défauts d'étanchéité. This combination notably makes it possible to considerably increase the mechanical resistance of the coating. The latter may, therefore, undergo deformations and / or stresses, in particular in shearing, without any harmful ruptures of the cover layer occurring which could cause leaks.
Par ailleurs, les caractéristiques du substrat, telles que son épaisseur, sa composition, la nature de la fibre de verre utilisée, son grainage etc..., peuvent être adaptées en fonction de l'emploi et, en particulier, du type de support que l'on veut revêtir. Furthermore, the characteristics of the substrate, such as its thickness, its composition, the nature of the glass fiber used, its graining, etc., can be adapted as a function of the use and, in particular, of the type of support. that we want to put on.
Comme précédemment mentionné, le revêtement selon l'invention peut faire l'objet de nombreuses applications. Il peut notamment servir à assurer la protection d'un matériau d'isolation tel qu'un panneau d'isolation thermique par exemple en mousse de matière plastique rigide ou semi-rigide. As previously mentioned, the coating according to the invention can be the subject of numerous applications. It can in particular be used to ensure the protection of an insulation material such as a thermal insulation panel, for example in rigid or semi-rigid plastic foam.
Dans ce cas, le substrat peut être directement appliqué sur le matériau d'isolation, par exemple la mousse de matière plastique. On peut ensuite passer la couche de couverture à l'aide de tous moyens connus pour ce type d' application. Ces opérations peuvent s'effectuer en usine ou, au moins partiellement, sur le chantier. In this case, the substrate can be directly applied to the insulation material, for example plastic foam. We can then pass the cover layer using any means known for this type of application. These operations can be carried out in the factory or, at least partially, on site.
On obtient ainsi un produit fini présentant de très bonnes caractéristiques d'isolation, d'étanchéité et de résistance au feu. A finished product is thus obtained having very good insulation, sealing and fire resistance characteristics.
Un mode de réalisation de l'invention sera décrit ci-après, à titre d'exemple non limitatif, avec référence aux dessins annexés dans lesquels
La figure l représente, en coupe schématique, une paroi réalisée à l'aide de panneaux d'isolation thermique utilisant un revêtement selon l'invention;
La figure 2 est une coupe schématique, à plus grande échelle, du revêtement selon l'invention.An embodiment of the invention will be described below, by way of non-limiting example, with reference to the accompanying drawings in which
FIG. 1 represents, in diagrammatic section, a wall produced using thermal insulation panels using a coating according to the invention;
Figure 2 is a schematic section, on a larger scale, of the coating according to the invention.
Telle que représentée figure i, la paroi est réalisée par assemblage de panneaux d'isolation thermique l, l', par exemple, en mousse de polyuréthane rigide ou en laine de roche, munis latéralement de profils d'assemblage de type à enture à mi-bois 2. As shown in Figure i, the wall is made by assembling thermal insulation panels l, l ', for example, in rigid polyurethane foam or rock wool, laterally provided with assembly profiles of the half-toe type. - wood 2.
Chacun de ces panneaux l, 1' se trouve recouvert d'un coté d' une couche de polyester stratifié armé de fibres de verre 3 qui constitue le susdit substrat. Each of these panels 1, 1 'is covered on one side with a layer of laminated polyester reinforced with glass fibers 3 which constitutes the above-mentioned substrate.
Pour améliorer l'étanchéité au niveau de l'assemblage des panneaux, cette couche 3 se prolonge d'un côté des panneaux l, l', au-delà de la languette 4 (partie 5) tandis qu'elle se termine, de 1' autre coté, à une distance correspondante du trait de coupe 6 de l'enture 2. To improve the seal at the level of the assembly of the panels, this layer 3 is extended on one side of the panels l, l ', beyond the tongue 4 (part 5) while it ends, by 1 on the other side, at a corresponding distance from the cutting line 6 of the groove 2.
Elle comprend en outre, le long de chacune de ses bordures latérales extérieures, une bande évidée 7 qui peut être comblée, après assemblage, par un enduit 8, de prérerence du polyester, servant à la fois de couvre-joint et de complément d'étanchéité. It further comprises, along each of its outer lateral edges, a hollowed-out strip 7 which can be filled, after assembly, with a coating 8, preferably polyester, serving both as a joint cover and as a complement to sealing.
En principe, l'ensemble constitué par les panneaux l, l' et la couche de polyester 3 est réalisé en usine. In principle, the assembly constituted by the panels l, l 'and the polyester layer 3 is produced in the factory.
Dans ce cas, il est possible
- soit de réaliser, dans un premier temps, les panneaux i, 1', puis d' appliquer ensuite la couche de résine de polyester armé 3, la polymérisation s'effectuant sur les panneaux l, 1'
- soit de réaliser la couche de polyester armé 3 puis de surmouler ensuite, sur cette couche, les panneaux l, l'. In this case, it is possible
- Either to realize, at first, the panels i, 1 ', then to apply the layer of reinforced polyester resin 3, the polymerization taking place on the panels l, 1'
- or to make the layer of reinforced polyester 3 and then to overmold, on this layer, the panels l, l '.
L'assemblage des panneaux 1, 1' est réalisé, de façon classique, en effectuant un collage au niveau des profils d'assemblage 2 et au niveau de la partie 5 de la couche 3 en polyester armé, sur le panneau 1, 1' adjacent (couche de colle 10). The assembly of the panels 1, 1 ′ is carried out, in a conventional manner, by bonding at the level of the assembly profiles 2 and at the level of the part 5 of the layer 3 of reinforced polyester, on the panel 1, 1 ′ adjacent (glue layer 10).
La paroi obtenue par cet assemblage est ensuite recouverte, du cote de la couche en polyester armé 3, d'une couche de couverture 12 à base de polyester armé d'écailles de verre. Cette couche de couverture 12 peut #tre exécutée par tous les moyens habituellement utilisés pour passer des enduits tels que les brosses, les pistolets, etc... En effet, en raison de la géométrie des écailles de verre 13 et de leur faculté de pouvoir se glisser les unes sur les autres lors de l'application, il est possible d'obtenir, par ces moyens connus, une couche d'épaisseur homogène et présentant un très bon fini (figure 2). The wall obtained by this assembly is then covered, on the side of the reinforced polyester layer 3, with a covering layer 12 based on polyester reinforced with glass flakes. This covering layer 12 can be carried out by all the means usually used for passing coatings such as brushes, guns, etc. In fact, because of the geometry of the glass flakes 13 and their ability to be able slip on each other during application, it is possible to obtain, by these known means, a layer of homogeneous thickness and having a very good finish (Figure 2).
En outre, lors de l'application, les écailles de verre 13 s'imbriquent les unes sur les autres parallèlement à la paroi, avec interposition de fines couches de polyester 14, de sorte qu'on obtient une couche parfaitement étanche à l'air et aux liquides, et qui présente une très haute résistance à l' abrasion, à la corrosion et au feu. Par ailleurs, il est possible de mélanger à la résine de polyester un pigment permettant d'obtenir une coloration désirée. In addition, during application, the glass flakes 13 overlap one another parallel to the wall, with the interposition of thin layers of polyester 14, so that a perfectly airtight layer is obtained. and liquids, and which has a very high resistance to abrasion, corrosion and fire. Furthermore, it is possible to mix with the polyester resin a pigment making it possible to obtain a desired coloration.
Il convient de noter que la nature et la teneur des éléments rentrant dans la constitution de la couche de couverture 12 peuvent varier en fonction de 1' utilisation. It should be noted that the nature and content of the elements included in the constitution of the cover layer 12 may vary depending on the use.
Toutefois, d'excellents résultats ont été obtenus à l'aide d' une couche de couverture 12 composée
- de 100 parties de résine polyester
- de 0,10 à 0,30 partie d'un agent d'ensimage, tel que du "Silam" produit par la Société "Union Carbide"
- de O à 2,5 parties d'un accélérateur de prise, tel que du Dirnéthyl Aniline à 10 'v
- de 0,3 à 1,00 partie d'un accélérateur de prise, tel que de l'Octoate de Cobalt à 6 %
- de O à 2,5 parties d'un agent thixotrepique
- de O à 10 parties de farine de silice
- de 10 à 70 parties d'écailles de verre
- de O à 3 parties de pigment par exemple à base de titane.However, excellent results have been obtained using a covering layer 12 composed
- 100 parts of polyester resin
- from 0.10 to 0.30 part of a sizing agent, such as "Silam" produced by the company "Union Carbide"
- from O to 2.5 parts of a setting accelerator, such as Dirnethyl Aniline at 10 'v
- from 0.3 to 1.00 part of a setting accelerator, such as 6% Cobalt Octoate
- from O to 2.5 parts of a thixotrepic agent
- from O to 10 parts of silica flour
- from 10 to 70 parts of glass flakes
- from O to 3 parts of pigment, for example based on titanium.
Il est clair que l'invention ne se limite pas à la réalisation de panneaux (plans) d'isolation thermique. En effet, le revetement selon l'invention peut servir à la protection de matériaux de forme et de nature très variées qui ne servent pas forcément à 1' isolation thermique. It is clear that the invention is not limited to the production of thermal insulation panels (plans). Indeed, the coating according to the invention can be used to protect materials of very varied shape and nature which are not necessarily used for thermal insulation.
