Description

Procédé de fabrication de plaques de revêtement de sol. Method of manufacturing floor covering plates.
L'invention concerne un procédé pour fabriquer des plaques en matériau synthétique pour revêtement de sols.The invention relates to a method for manufacturing plates of synthetic material for floor covering.
On utilise depuis plusieurs années des plaques minces en matériau synthétique pour recouvrir des sols plans préalablement ragréés. Ces plaques ont en général une forme carrée ou rectangulaire et sont tirées de bandes minces en matériau synthétique.Thin sheets of synthetic material have been used for several years to cover previously leveled flat floors. These plates generally have a square or rectangular shape and are drawn from thin strips of synthetic material.
On ne connaît pas actuellement de plaques en matériau synthétique qui puissent être utilisées pour la répartition de sols revêtus de revêtements anciens en céramique, tels que les tomettes anciennes de couleur brique et de forme hexagonale. La forme de ces tomettes, leur épaisseur, et leur usure et patine nécessitent de remplacer les tomettes abîmées par d'autres tomettes du même type et de préférence de même âge et de même provenance, ce qui pose des problèmes difficiles à résoudre.Currently, there are no known sheets of synthetic material which can be used for the distribution of floors coated with old ceramic coverings, such as old brick-colored tiles and hexagonal in shape. The shape of these tiles, their thickness, and their wear and patina require replacing the damaged tiles with other tiles of the same type and preferably of the same age and from the same origin, which poses problems which are difficult to solve.
Le but de l'invention est de proposer un procédé pour réaliser des plaques de revêtement qui puissent répondre notamment à ces besoins. Il est évident que les plaques obtenues par le procédé selon l'invention peuvent également être utilisées pour revêtir en totalité un sol nu préalablement ragréé.The object of the invention is to propose a method for producing covering plates which can meet these needs in particular. It is obvious that the plates obtained by the process according to the invention can also be used to completely cover bare, previously leveled soil.
Le procédé selon l'invention est caractérisé par le fait que l'on coule dans un bac de moulage une résine de polyuréthanne ayant une dureté comprise entre 70 et 85 shore A, cette résine étant constituée de deux composants de base, à savoir du polyol et de l'isocyanate dans la proportion pondérale de 100 parts de polyol pour 25 parts d'isocyanate, et de six additifs exprimés ci-après dans une proportion pondérale par rapport au poids total des deux composants de base :The method according to the invention is characterized in that a polyurethane resin having a hardness of between 70 and 85 shore A is poured into a molding tank, this resin consisting of two basic components, namely polyol and isocyanate in the proportion by weight of 100 parts of polyol per 25 parts of isocyanate, and of six additives expressed below in a proportion by weight relative to the total weight of the two basic components:
- 30 à 50 % d'une charge de silice assurant la structure antiusure, - 15 à 25 % de brique pyrogénée assurant la pigmentation, - 5 à l0 % d'agent plastifiant,- 30 to 50% of a silica filler ensuring the anti-wear structure, - 15 to 25% of pyrogenic brick ensuring the pigmentation, - 5 to 10% of plasticizing agent,
- 1 à 3 % d'agent anti ultra-violet, - 1 à 3 % d'agent anti oxydant, et- 1 to 3% of anti-ultraviolet agent, - 1 to 3% of antioxidant, and
- 0,2 à 0,5 % d'un catalyseur accélérant.- 0.2 to 0.5% of an accelerating catalyst.
Avantageusement on prémélange les six additifs dans le polyol, et on mélange l'isocyanate et le polyol enrichi des additifs lors de la coulée. De préférence l'épaisseur de la plaque coulée est de 5mm environ.Advantageously, the six additives are premixed in the polyol, and the isocyanate and the polyol enriched with the additives are mixed during casting. Preferably the thickness of the casting plate is approximately 5mm.
Cette épaisseur associée à la présence de silice assure une rigidité suffisante à la plaque réalisée par le procédé, ce qui permet au carreleur de travailler comme s'il s'agissait d'un élément unitaire de revêtement de sol en céramique.This thickness associated with the presence of silica ensures sufficient rigidity to the plate produced by the process, which allows the tiler to work as if it were a unitary element of ceramic flooring.
Afin d'obtenir la patine de surface souhaitée, on vaporise au fond du bac de moulage, avant la coulée, un vernis de gel « coat » de polyuréthanne nuancé. Pour favoriser le durcissement de la plaque, on effectue après la coulée une post-cuisson à une température comprise entre 60 et 80°C.In order to obtain the desired surface patina, a spray of nuanced polyurethane gel coat is sprayed onto the bottom of the molding tank before casting. To favor the hardening of the plate, post-baking is carried out after casting at a temperature between 60 and 80 ° C.
Pour éviter d'appliquer un agent de démoulage, on utilise des bacs de moulage en élastomère de silicone.To avoid applying a release agent, silicone elastomer molding tanks are used.
De préférence, les bacs de moulage sont obtenus à partir d'une empreinte d'un sol carrelé.Preferably, the molding trays are obtained from an imprint of a tiled floor.
Très avantageusement l'empreinte recouvre une pluralité d'éléments unitaires juxtaposés du sol carrelé. Ces éléments unitaires sont par exemple des tomettes.Very advantageously the imprint covers a plurality of unit elements juxtaposed on the tiled floor. These unitary elements are for example tomettes.
D'autres avantages et caractéristiques de l'invention ressortiront à la lecture de la description suivante faite à titre d'exemple et en référence aux dessins annexés dans lesquels :Other advantages and characteristics of the invention will emerge on reading the following description given by way of example and with reference to the appended drawings in which:
La figure 1 montre un carrelage traditionnel en tomettes anciennes sur lequel on prélève une empreinte, à partir de laquelle sont réalisés des bacs de moulage ; La figure 2 est une vue de dessus d'un bac de moulage ;Figure 1 shows a traditional tiling in old tiles on which we take an imprint, from which are made molding trays; Figure 2 is a top view of a molding tray;
La figure 3 est une coupe selon la ligne HT HT de la figure 2 du bac de moulage ;Figure 3 is a section along the line HT HT of Figure 2 of the molding pan;
La figure 4 montre le principe d'une installation pour mettre en œuvre l'invention ; et La figure 5 montre en perspective une plaque de revêtement de sol réalisée par le procédé selon l'invention.FIG. 4 shows the principle of an installation for implementing the invention; and Figure 5 shows in perspective a floor covering plate produced by the method according to the invention.
La figure 1 montre un carrelage 1 ancien traditionnel en tomettes, chaque tomette a une forme hexagonale régulière et la distance séparant deux angles opposés est par exemple de 24 cm. Sur ce carrelage 1 on prélève une empreinte 2 très précise de six tomettes juxtaposées réparties en deux rangées de trois tomettes par des méthodes connues. Le contour de cette empreinte est montré par la ligne fermée brisée référencée 3.Figure 1 shows a traditional old tile 1 in tiles, each tile has a regular hexagonal shape and the distance between two opposite angles is for example 24 cm. On this tiling 1 we take a very precise imprint 2 of six juxtaposed tomettes distributed in two rows of three tomettes by known methods. The outline of this imprint is shown by the broken closed line referenced 3.
A partir de cette empreinte on réalise un outil de moulage servant à fabriquer les bacs de moulage 4 des plaques selon l'invention. Les figures 2 et 3 montrent le bac de moulage 4 réalisé en élastomère de silicone dont le fond présente une empreinte identique à l'empreinte 1 réalisée et complémentaire de celle des plaques à réaliser.From this imprint, a molding tool is used which is used to manufacture the molding trays 4 for the plates according to the invention. Figures 2 and 3 show the molding tray 4 made of silicone elastomer, the bottom of which has an imprint identical to the imprint 1 produced and complementary to that of the plates to be produced.
On voit notamment les nervures 5 qui correspondent aux joints des tomettes utilisées pour prélever l'empreinte initiale. La figure 4 montre l'installation 10 utilisée pour mettre en œuvre l'invention. Cette installation comporte un châssis 11 supportant un bacWe see in particular the ribs 5 which correspond to the joints of the tiles used to take the initial imprint. FIG. 4 shows the installation 10 used to implement the invention. This installation comprises a frame 11 supporting a tank
12 contenant le polyol enrichi des six additifs et un bac 13 contenant de l'isocyanate. Des agitateurs permettent d'homogénéiser en permanence les produits contenus dans les bacs 12 et 13. Des pompes amènent le polyol enrichi des six additifs et l'isocyanate vers une tête de coulée 14 par intermédiaire de conduits séparés 15 et 16. La tête de coulée 14 est disposée au-dessus d'un bac de moulage 4 et est équipée d'une poignée de manœuvre 17 qui permet de faire couler et mélanger une dose de polyol enrichi des six additifs et une dose d'isocyanate dans un bac de moulage 4.12 containing the polyol enriched with the six additives and a tank 13 containing isocyanate. Stirrers are used to permanently homogenize the products contained in tanks 12 and 13. Pumps bring the polyol enriched with the six additives and the isocyanate to a casting head 14 via separate conduits 15 and 16. The casting head 14 is placed above a molding tank 4 and is equipped with an operating handle 17 which makes it possible to pour and mix a dose of polyol enriched with the six additives and a dose of isocyanate in a molding tank 4 .
L'installation comporte naturellement des moyens pour régler les doses dans les proportions définies dans l'introduction.The installation naturally includes means for adjusting the doses in the proportions defined in the introduction.
Typiquement, avec le bac de moulage 4 qui correspond à six tomettes de 24 cm de diamètre en deux angles opposés, le poids total des deux doses est de 1,5 kg environ et l'épaisseur du mélange déversé au fond du bac de moulage est de 0,5 cm.Typically, with the molding pan 4 which corresponds to six 24 cm diameter tiles at two opposite angles, the total weight of the two doses is approximately 1.5 kg and the thickness of the mixture poured into the bottom of the molding pan is 0.5 cm.
Pour accélérer le durcissement de la plaque réalisée, les bacs de moulage sont introduits, après la coulée, dans une chambre de cuisson, où ils sont soumis à une température comprise entre 60 et 80°C pendant une durée comprise entre 5 et 10 rninutes.To accelerate the hardening of the plate produced, the molding tanks are introduced, after casting, in a baking chamber, where they are subjected to a temperature between 60 and 80 ° C for a period of between 5 and 10 minutes.
Il suffit ensuite de démouler les plaques, de les ébarber, de les conditionner et de les stocker.It then suffices to unmold the plates, to deburr them, to condition them and to store them.
Pour obtenir la patine de surface souhaitée, on vaporise au fond des bacs de moulage 4 un vernis de gel « coat » avant de procéder à la coulée. On attend 3 à 5 minutes avant de couler une nouvelle plaque, afin de permettre la prise du gel « coat ». H va de soi que l'empreinte 2 peut être réalisée sur tout type de carrelage traditionnel sans sortir du cadre de l'invention.To obtain the desired surface patina, a spray of “coat” gel varnish is sprayed onto the bottom of the molding trays 4 before casting. We wait 3 to 5 minutes before pouring a new plate, to allow the setting of the gel "coat". It goes without saying that the imprint 2 can be made on any type of traditional tiling without departing from the scope of the invention.
La figure 5 montre une plaque 20 réalisée selon le procédé décrit ci-dessus. Ces plaques 20 ont des contours tels qu'ils s'emboîtent les uns dans les autres lors de la pose. Ces plaques 20 sont fixées sur un sol plan, propre et sec avec une colle acrylique. Elles ont une dimension hors tout de 42 x 73 cm, ce qui leur donne une certaine souplesse permettant une pose sur un sol légèrement déformé.FIG. 5 shows a plate 20 produced according to the method described above. These plates 20 have contours such that they fit into each other during installation. These plates 20 are fixed on a flat, clean and dry floor with an acrylic adhesive. They have an overall dimension of 42 x 73 cm, which gives them a certain flexibility allowing a pose on a slightly deformed ground.
Les plaques 20 obtenues par le procédé ont une grande résistance au piétinement, aux taches diverses, et une bonne tenue aux brûlures de cigarettes. Elles peuvent être utilisées pour recouvrir les sols des passages, hall d'entrée, cuisine etc. Elles peuvent également être utilisées dans les salles de bains du fait de leur étanchéité. The plates 20 obtained by the method have a high resistance to trampling, various stains, and good resistance to cigarette burns. They can be used to cover the floors of passageways, entrance halls, kitchens, etc. They can also be used in bathrooms because of their tightness.
