The subject of the invention is a new composite material comprising a base layer consisting of a polyester-based resin and at least one melamine coating layer, a process for manufacturing such a composite material and the applications of this material. in particular the manufacture of trays for all uses.
De tels matériaux composites sont connus, mais leur fabrication présente des difficultés, le polyester et la mélamine étant des résines incompatibles, c'est-à-dire ne pouvant se fixer convenablement l'une à l'autre. Such composite materials are known, but their manufacture presents difficulties, polyester and melamine being incompatible resins, that is to say which cannot be fixed properly to each other.
Cette difficulté peut être tournée en interposant entre la couche de polyester et la couche de mélamine une ou plusieurs résines synthétiques compatibles avec le polyester d'une part et avec la mélamine d'autre part. This difficulty can be overcome by interposing between the polyester layer and the melamine layer one or more synthetic resins compatible with polyester on the one hand and with melamine on the other hand.
L'invention concerne la découverte d'un tel nouveau matériau composite. The invention relates to the discovery of such a new composite material.
Le matériau composite de l'invention se caractérise en ce qu'il comporte pour assurer la jonction de la résine à base de polyester et de la couche de revêtement à base de mélamine au moins une couche de jonction intermédiaire à base de résine phénolique. The composite material of the invention is characterized in that it comprises to ensure the junction of the polyester-based resin and the coating layer based on melamine at least one intermediate junction layer based on phenolic resin.
Avantageusement la couche de jonction intermédiaire est en fait constituée d'au moins une et de préférence de deux feuilles superposées de papier kraft ou papier d'emballage comparable imprégnées d'une résine phénolique. Advantageously, the intermediate junction layer consists in fact of at least one and preferably of two superimposed sheets of kraft paper or comparable wrapping paper impregnated with a phenolic resin.
Le procédé de fabrication du matériau se caractérise quant à lui en ce que le sandwich constitué de la couche à base de polyester, de la couche intermédiaire à base de résine phénolique et de la couche de revêtement mélaminée sont réunies entre elles par une seule opération de moulage sous pression en utilisant une pression de moulage de l'ordre de quelques centaines de bars, une température de moule comprise entre 120 et 180"C et une durée de cuisson de l'ordre de quelques minutes. The material manufacturing process is characterized in that the sandwich consisting of the polyester-based layer, the phenolic resin-based intermediate layer and the melamine-coated layer are joined together by a single operation. pressure molding using a molding pressure of the order of a few hundred bars, a mold temperature between 120 and 180 "C and a cooking time of the order of a few minutes.
L'invention permet notamment la fabrication de plateaux pour tous usages, de qualité de résistance améliorée et de faible poids. The invention allows in particular the manufacture of trays for all uses, of improved resistance quality and low weight.
L'invention et sa mise en oeuvre apparaîtront plus clairement à l'aide de la description qui va suivre faite en référence aux dessins annexés dans lesquels
- La figure 1 montre de façon schématique la composition du "sandwich" des matériaux à assembler avant leur pressage à chaud.The invention and its implementation will appear more clearly with the aid of the description which follows, given with reference to the appended drawings in which
- Figure 1 shows schematically the composition of the "sandwich" of the materials to be assembled before their hot pressing.
- La figure 2 montre de façon schématique le positionnement du "sandwich" de la figure 1 dans un moule avant fermeture. - Figure 2 shows schematically the positioning of the "sandwich" of Figure 1 in a mold before closing.
- La figure 3 montre en coupe un plateau ainsi fabriqué. - Figure 3 shows in section a tray thus manufactured.
- La figure 4 montre en coupe le détail agrandi à l'endroit entouré IV dans la figure 3. - Figure 4 shows in section the enlarged detail at the place surrounded IV in Figure 3.
On décrira l'invention à l'aide d'un mode de réalisation uniquement donné à titre d'exemple. The invention will be described using an embodiment only given by way of example.
En se référant aux dessins on a expliqué la fabrication d'un plateau par exemple utilisé dans des services de restauration rapide. Referring to the drawings we explained the manufacture of a tray for example used in fast food services.
En faisant référence à la figure 1, le plateau sera constitué à partir d'un matériau composite comprenant une couche répérée 1 de décor constituée par une feuille de papier convenablement décorée imprégnée de mélamine ; une couche de résistance formant le support du plateau repérée 2 constituée de fibres de verre en nappe imprégnées de polyester. Cette couche 2 pourra être constituée par exemple elle-même de trois couches superposées de nappes de fibres de verre ainsi imprégnées. De façon à assurer après moulage à chaud la compatibilité entre la couche 1 et la couche 2, on interpose entre les deux couches une couche phénolique 3 constituée d'un papier épais résistant tel que du papier kraft imprégné de résine phénolique. La couche 3 est avantageusement constituée en fait de deux telles couches de papier kraft superposées. Referring to Figure 1, the tray will be made from a composite material comprising a layer of decorative decoration 1 consisting of a sheet of suitably decorated paper impregnated with melamine; a resistance layer forming the support of the plate marked 2 consisting of glass fibers in a sheet impregnated with polyester. This layer 2 could for example consist of three superimposed layers of glass fiber layers thus impregnated. In order to ensure compatibility between layer 1 and layer 2 after hot molding, a phenolic layer 3 is interposed between the two layers, consisting of a thick resistant paper such as kraft paper impregnated with phenolic resin. Layer 3 advantageously consists in fact of two such layers of superimposed kraft paper.
Dans un exemple de réalisation, on est ainsi parti pour constituer des plateaux de dimension sensiblement 50 x 40 cm, de
- une couche 2 de résine à base de polyester divisée en trois couches de fibres de verre longues en nappe pré-imprégnées de polyester pour un poids total de 800 grammes,
- une couche intermédiaire phénolique constituée de deux feuilles de papier kraft à la dimension de l'ébauche du plateau imprégnées de résine phénolique à 40 % pour un poids total de 110 grammes ; l'épaisseur totale de la couche 3 était de l'ordre de 0,6 mm
- une couche décor de revêtement 1 constituée d'une feuille de papier décorée d'épaisseur d'environ 0,15 mm à la dimension de l'ébauche du plateau et imprégnée de mélanine.In an exemplary embodiment, we thus left to constitute trays of dimension substantially 50 x 40 cm, of
a layer 2 of polyester-based resin divided into three layers of long glass fibers in a sheet pre-impregnated with polyester for a total weight of 800 grams,
- a phenolic intermediate layer consisting of two sheets of kraft paper the size of the blank of the tray impregnated with 40% phenolic resin for a total weight of 110 grams; the total thickness of layer 3 was of the order of 0.6 mm
- A decorative coating layer 1 consisting of a decorated sheet of paper about 0.15 mm thick to the dimension of the blank of the tray and impregnated with melanin.
Le sandwich composé des trois couches 1, 2 et 3 est alors disposé comme indiqué à la figure 2 dans un moule entre poinçon 4 et matrice 5. Le moule est porté à une température comprise entre 120 et 180 C, et de préférence voisine de 140"C. Après mise en place des trois couches dans le moule, le moule est fermé. On utilise une pression de fermeture de quelques centaines de bars, par exemple comprise entre 200 et 250 bars, avantageusement égale à 230 bars. Dans de telles conditions de température et de pression, le plateau est cuit après un maintien dans le moule de trois à quatre minutes. The sandwich composed of the three layers 1, 2 and 3 is then placed as shown in FIG. 2 in a mold between punch 4 and die 5. The mold is brought to a temperature between 120 and 180 C, and preferably close to 140 "C. After the three layers have been placed in the mold, the mold is closed. A closing pressure of a few hundred bars is used, for example between 200 and 250 bars, advantageously equal to 230 bars. Under such conditions temperature and pressure, the tray is cooked after being kept in the mold for three to four minutes.
Avantageusement le moule est fermé progressivement, par exemple pendant deux secondes sous une pression réduite de l'ordre de 80 % de la pression finale, soit dans l'exemple indiqué sous 180 bars pendant quelques secondes, par exemple deux secondes pour assurer le dégazage de l'air pouvant être inclus. Advantageously, the mold is closed gradually, for example for two seconds under a reduced pressure of the order of 80% of the final pressure, that is to say in the example indicated under 180 bars for a few seconds, for example two seconds to ensure the degassing of air may be included.
Après pressage, le plateau est extrait puis détouré. Dans l'exemple indiqué, le plateau fini de 48/37 centimètres pèse 910 grammes, soit un poids d'environ 0,5 grammes/cm2. Le produit fini a un très bel aspect et une résistance améliorée. After pressing, the plate is extracted and then cut out. In the example shown, the finished 48/37 cm tray weighs 910 grams, or a weight of about 0.5 grams / cm2. The finished product has a very beautiful appearance and improved resistance.
Le matériau composite peut être utilisé bien entendu pour de multiples applications, et notamment pour fabriquer des tables, des revêtements de mobiliers, de cuisines, d'ateliers ou de bureaux, etc... The composite material can of course be used for multiple applications, and in particular for manufacturing tables, coverings for furniture, kitchens, workshops or offices, etc.
Diverses variantes peuvent être apportées au mode de fabrication décrit. Ainsi notamment on peut utiliser à la place de la feuille décor 1 constituée d'une feuille décorée impregnée de mélamine deux feuilles superposées, une de papier décoré sec et une de papier neutre imprégnée de mélamine que l'on placera par dessus l'autre, pour la fabrication du produit fini. Various variants can be made to the manufacturing method described. Thus, in particular, it is possible to use, in place of the decor sheet 1 consisting of a decorated sheet impregnated with melamine, two superimposed sheets, one of dry decorated paper and one of neutral paper impregnated with melamine which will be placed over the other, for the production of the finished product.
