Description
<Desc/Clms Page number 1>
La présente invention a pour objet un procédé de fabri- cation d'articles polychromes en matières plastiques, tels que plateaux ménagers ou autres, panneaux indicateurs ou signalisa- teurs, supports publicitaires, revêtements décoratifs, etc..
Suivant les procédés usuels de mise en oeuvre des matiè- res plastiques, par moulage avec polymérisation, des articles ,de ce genre ne sont généralement obtenus qu'en une seule couleur.
Pour leur donner une décoration, on doit les teinter en surface ce qui représente un travail long et onéreux, les motifs restant d'ailleurs extérieurs et sujets à détériorations par chocs, frottements ou toute autre causer
Le procédé selon l'invention à pour but de permettre d'obtenir de façpn commode et rapide de tels effets décoratifs qui soient inaltérables.
<Desc/Clms Page number 2>
Ce procédé est caractérisé en ce que l'on imprime les dessins dont on veut décorer l'article sur une feuille fibreuse perméable à la matière plastique, l'on pose cette feuille portant les impressions sur une couche-support que l'on recouvre d'une autre couche de matière plastique avant compression à chaud pour obtenir la polymérisation.
La feuille fibreuse recevant par impression les dessins ou décorations peut tre un papier non encollé genre buvard ou, mieux, un tissu usuel à fibres végétales ou artificielles. De préférence on utilise un tissu à mailles lâches, lequel peut être sans apprêt. Notamment, un tissu de fibres artificielles, telles que rayonne ou autre, convient bien.
La feuille ainsi constituée est mise en place sur la couche-support, laquelle peut être une couche de matière plasti- que ou encore une couche de fibre de verre. Elle est ensuite recouverte d'une autre couche de matière plastique. Le tout est soumis ensuite à la polymérisation. Au cours de cette opération, la matière plastique fluide imprègne la feuille fibreuse et la traverse même pour faire corps avec la couche-support en empri- sonnant la feuille décorée. Les dessins de celle-ci, visibles par transparence, se trouvent protégés contre toute action exté- rieure.
Pour l'application du procédé, on peut utiliser des matières plastiques diverses de la gamme des thermoplastiques.
Toutefois les résultats les meilleurs sont obtenus avec les résines du genre polyesters. De telles résines se prêtent bien à la réunion de la couche-support avec la couche apposée ensuite et avec la feuille décorée intercalaire, de façon à constituer un ensemble indéfiniment stable et de bonne rigidité.
Par ce procédé, l'obtention de motifs décoratifs les plus variés est réalisée sans avoir à modifier les conditions de mise en oeuvre de la matière plastique et sans qu'un outillage spécial soit nécessaire. Cet outillage consiste dans les presses
<Desc/Clms Page number 3>
@ usuelles agencées pour assurer le moulage à chaud, aux tempéra- tures de polymérisation.
La variété des dessins, coloris, dépend exclusivement des impressions de la feuille fibreuse intercalaire, ces impres- sions étant réalisées séparément et préalablement en dehors du cycle même de fabrication des articles à réaliser.
Autrement dit, on fait imprimer des feuilles de papier non encollé ou de tissu lâche avec ou sans apprêt avec de multi- ples dessins choisis, en quantités notables et à faible prix de revient. Ces feuilles sont stockées pour n'être utilisées qu'au fur et à mesure des besoins, entrant dans le cycle d'une fabrica- tion continue non différenciée, et donnant cependant des articles à dessins différents, ce qui permet une production économique* Cette,façon de procéder est nettement plus économique que la colo ration individuelle d'articles après fabrication de'ceux-ci.
Dans la mise en oeuvre du procédé, pour faire bénéficier l'article fini de l'éclat et de la qualité des dessins imprimés, il importe d'éviter que des bulles d'air ou de vapeur se trouvent emprisonnées dans la résine, notamment au contact de la feuille fibreuse incorporée. A cet effet, on utilise une feuille fibreuse dépourvue d'humidité et, si besoin est, on procède à un séchage de celle-ci avant son application sur la couche-support de résine.
D'autre part, il y a parfois intérêt à appliquer sur la couche-support, avant de poser la feuille fibreuse munie d'impres- sions, une légère couche de résine brute. Cette application peut s'effectuer au pistolet ou à la brosse. C'est alors sur la couche de résine brute que l'on pose la feuille fibreuse qui s'imprègne de résine avant de recevoir la couche supérieure de revêtement.
Afin de donner de la consistance à l'article ainsi fabri- qué, il.y a souvent intérêt à prévoir dans la couche-support de matière plastique des éléments d'armature, en toute matière conve- nable. En particulier, on réalise cette armature au moyen de fibre
<Desc/Clms Page number 4>
de verre convenablement répartie dans la masse de la couche-support
Le procédé permet d'obtenir, à bas prix de revient, des articles de ménage, tels que des plateaux, présentant des dessins nombreux et réalisant des effets décoratifs variés. Il s'appli- que à la fabrication en série de panneaux signalisateurs ou publicitaires, légers, inaltérables, remplaçant avantageusement les panneaux usuels en tôle peinte ou émaillée.
Ces divers articles peuvent, en plus de l'élément décora= tif incorporé, recevoir en surface par moulage ou autrement, des conformations variées, réalisant des effets décoratifs ou esthé- tiques complémentaires. On peut aussi incorporer dans la couche de revêtement, localement ou sur toute sa superficie, des élément accessoires, notamment des petites billes de verre donnant des effets de réflexion originaux.
<Desc / Clms Page number 1>
The present invention relates to a process for manufacturing polychrome plastic articles, such as household or other trays, signage or signage panels, advertising media, decorative coverings, etc.
According to the usual processes for using plastics, by molding with polymerization, articles of this type are generally obtained only in one color.
To give them a decoration, they must be tinted on the surface which represents a long and expensive work, the patterns remaining external and subject to deterioration by shocks, friction or any other cause
The object of the method according to the invention is to make it possible to obtain, in a convenient and rapid manner, such decorative effects which are unalterable.
<Desc / Clms Page number 2>
This process is characterized in that the designs with which the article is to be decorated are printed on a fibrous sheet permeable to the plastic material, this sheet bearing the prints is placed on a support layer which is covered with another layer of plastic material before hot compression to obtain polymerization.
The fibrous sheet receiving the designs or decorations by printing can be an unsized blotting-type paper or, better, a usual fabric made from plant or artificial fibers. Preferably, a loose mesh fabric is used, which may be unfinished. In particular, a fabric of artificial fibers, such as rayon or the like, is suitable.
The sheet thus formed is placed on the support layer, which can be a layer of plastic material or a layer of glass fiber. It is then covered with another layer of plastic. The whole is then subjected to polymerization. During this operation, the flowable plastic material impregnates the fibrous sheet and even passes through it to form one body with the support layer by entangling the decorated sheet. The drawings thereof, visible by transparency, are protected against any external action.
For the application of the process, it is possible to use various plastics from the range of thermoplastics.
However, the best results are obtained with resins of the polyester type. Such resins lend themselves well to joining the support layer with the layer subsequently affixed and with the decorated interlayer sheet, so as to constitute an indefinitely stable unit of good rigidity.
By this process, the most varied decorative patterns are obtained without having to modify the conditions of processing of the plastic material and without special tools being necessary. This tooling consists of the presses
<Desc / Clms Page number 3>
@ customary designed to ensure hot molding, at polymerization temperatures.
The variety of designs and colors depends exclusively on the impressions of the fibrous interlayer sheet, these impressions being made separately and beforehand outside the actual manufacturing cycle of the articles to be produced.
In other words, sheets of unsized paper or loose fabric with or without a finish are printed with a number of selected designs, in substantial quantities and at low cost. These sheets are stored so that they can only be used as and when required, entering the cycle of continuous undifferentiated manufacturing, and yet giving articles with different designs, which allows economical production. This method is significantly more economical than the individual coloring of articles after manufacture thereof.
In carrying out the process, in order to provide the finished article with the luster and the quality of the printed designs, it is important to prevent air or vapor bubbles from being trapped in the resin, in particular in the resin. contact of the incorporated fibrous sheet. For this purpose, a fibrous sheet devoid of moisture is used and, if necessary, it is dried before its application to the resin support layer.
On the other hand, it is sometimes advantageous to apply to the support layer, before laying the fibrous sheet provided with prints, a light layer of raw resin. This application can be carried out with a spray gun or with a brush. It is then on the raw resin layer that the fibrous sheet is placed which is impregnated with resin before receiving the upper coating layer.
In order to give consistency to the article thus produced, it is often advantageous to provide reinforcing elements in the plastics support layer, of any suitable material. In particular, this reinforcement is produced by means of fiber
<Desc / Clms Page number 4>
of glass suitably distributed in the mass of the support layer
The process makes it possible to obtain, at low cost, household items, such as trays, having numerous designs and achieving various decorative effects. It is applicable to the mass production of signage or advertising panels, light, unalterable, advantageously replacing the usual panels in painted or enamelled sheet.
These various articles can, in addition to the decorative element incorporated, receive on the surface by molding or otherwise, various conformations, achieving complementary decorative or aesthetic effects. It is also possible to incorporate into the coating layer, locally or over its entire surface, accessory elements, in particular small glass balls giving original reflection effects.
