Description
La présente invention concerne un profilé et son procédé de fabrication.The present invention relates to a profile and its method of manufacture.
Elle concerne en particulier un profilé comprenant un corps et un revêtement dudit corps, ledit revêtement comprenant au moins une encre et un vernis.It relates in particular to a profile comprising a body and a coating of said body, said coating comprising at least one ink and one varnish.
La réalisation de décors par impression jet d’encre sur des profilés métalliques utilisés dans la construction est connue. Dans le cas de profilés en matière de synthèse, il est de plus en plus fréquemment utilisé des matières recyclées. La difficulté est alors de réussir à réaliser de manière reproductible un profilé notamment en termes d’aspect puisque la couleur des matières recyclées est imprévisible.The production of decorations by inkjet printing on metal profiles used in construction is known. In the case of profiles made of synthetic material, it is more and more frequently used recycled materials. The difficulty is then to succeed in producing a profile in a reproducible way, particularly in terms of appearance since the color of the recycled materials is unpredictable.
Un but de l’invention est de proposer un profilé dont la conception permet l’utilisation de matière recyclée sans nuire à la maîtrise de l’aspect dudit profilé.An object of the invention is to provide a profile whose design allows the use of recycled material without harming the control of the appearance of said profile.
Un autre but de l’invention est de proposer un profilé dont la conception permet de maîtriser l’aspect pour permettre une reproductibilité de l’aspect d’un profilé à un autre.Another object of the invention is to provide a profile whose design makes it possible to control the appearance to allow reproducibility of the appearance from one profile to another.
A cet effet, l’invention a pour objet un profilé comprenant un corps et un revêtement au moins partiel dudit corps, ledit revêtement comprenant au moins une encre et un vernis, caractérisé en ce que le corps est formé d’une âme et d’une peau, en ce que l’âme et la peau comprennent au moins du polychlorure de vinyle (PVC), en ce que la peau est de couleur blanche, en ce que l’épaisseur de la peau est au moins égale à 0,5 mm et en ce que la surface dite externe de la peau recouverte au moins partiellement par le revêtement est une surface rugueuse. La réalisation du corps du profilé sous forme d’une âme et d’une peau avec des caractéristiques spécifiques de la peau en termes de couleur, d’épaisseur et d’aspect de surface permet de maîtriser parfaitement l’aspect extérieur du corps. Il en résulte la possibilité d’utiliser des matières quelconques y compris des matières recyclées pour l’âme sans nuire à l’aspect final du profilé.To this end, the subject of the invention is a profile comprising a body and an at least partial coating of said body, said coating comprising at least one ink and one varnish, characterized in that the body is formed of a core and of a skin, in that the core and the skin comprise at least polyvinyl chloride (PVC), in that the skin is white in color, in that the thickness of the skin is at least equal to 0.5 mm and in that the so-called outer surface of the skin covered at least partially by the coating is a rough surface. The production of the body of the profile in the form of a core and a skin with specific characteristics of the skin in terms of color, thickness and surface appearance allows to perfectly control the external appearance of the body. This results in the possibility of using any materials including recycled materials for the core without harming the final appearance of the profile.
Selon un mode de réalisation de l’invention, le corps est une pièce extrudée. Il en résulte une simplicité de fabrication.According to one embodiment of the invention, the body is an extruded part. This results in simplicity of manufacture.
Selon un mode de réalisation de l’invention, l’âme et la peau du corps sont coextrudées. Le revêtement de l’âme par une peau aux caractéristiques spécifiques permet de maîtriser les caractéristiques extérieures du corps y compris dans le cas d’une âme réalisée en matière recyclée.According to one embodiment of the invention, the core and the skin of the body are coextruded. Covering the core with a skin with specific characteristics makes it possible to control the external characteristics of the body, including in the case of a core made of recycled material.
Selon un mode de réalisation de l’invention, le polychlorure de vinyle de l’âme du corps est un polychlorure de vinyle expansé. Cette caractéristique permet d’alléger l’âme au profit de la conception d’une peau plus épaisse. Le poids total du corps peut ainsi être conservé.According to one embodiment of the invention, the polyvinyl chloride of the core of the body is an expanded polyvinyl chloride. This feature makes it possible to lighten the core in favor of the design of a thicker skin. The total body weight can thus be retained.
Selon un mode de réalisation de l’invention, l’âme du corps est une âme composite contenant en sus du liant formé par le polychlorure de vinyle (PVC), au moins une charge. Il en résulte une résistance mécanique accrue du profilé sans nuire à la maîtrise de l’aspect.According to one embodiment of the invention, the core of the body is a composite core containing, in addition to the binder formed by polyvinyl chloride (PVC), at least one filler. This results in increased mechanical strength of the profile without compromising control of the appearance.
Selon un mode de réalisation de l’invention, la ou au moins l'une des charges de l’âme composite du corps est de la fibre d’anas de lin.According to one embodiment of the invention, the or at least one of the fillers of the composite core of the body is flax shavings fibre.
Selon un mode de réalisation de l’invention, l’encre et le vernis du revêtement sont choisis parmi les composés réticulables aux UV. Il en résulte une possibilité d’impression rapide du corps du profilé.According to one embodiment of the invention, the ink and the varnish of the coating are chosen from compounds crosslinkable by UV. This results in the possibility of rapid printing of the body of the profile.
Selon un mode de réalisation de l’invention, le revêtement est un revêtement d’impression imprimé sur le corps.According to one embodiment of the invention, the coating is an impression coating printed on the body.
Selon un mode de réalisation de l’invention, l’encre est une encre pigmentée contenant des pigments inorganiques. La présence pigments inorganiques, c’est-à-dire de minéraux, permet d’offrir une tenue aux ultra-violets (UV) améliorée.According to one embodiment of the invention, the ink is a pigmented ink containing inorganic pigments. The presence of inorganic pigments, i.e. minerals, provides improved ultraviolet (UV) resistance.
L’invention a encore pour objet un procédé de fabrication d’un profilé comprenant un corps et un revêtement dudit corps, ledit revêtement comprenant au moins une encre et un vernis, ledit procédé comprenant une étape de fabrication dudit corps et une étape de recouvrement au moins partiel dudit corps par ledit revêtement caractérisé en ce que le profilé étant du type précité, l’étape de fabrication dudit corps comprend au moins une phase de coextrusion de l’âme et de la peau du corps et une phase de ponçage de la peau dudit corps.Another subject of the invention is a process for manufacturing a profile comprising a body and a coating of said body, said coating comprising at least one ink and a varnish, said process comprising a step of manufacturing said body and a step of covering with less part of said body by said coating characterized in that the profile being of the aforementioned type, the step of manufacturing said body comprises at least one phase of coextrusion of the core and the skin of the body and a phase of sanding the skin of said body.
L'invention sera bien comprise à la lecture de la description suivante d'exemples de réalisation, en référence aux dessins annexés dans lesquels :The invention will be better understood on reading the following description of exemplary embodiments, with reference to the appended drawings in which:
Comme mentionné ci-dessus, l'invention a pour objet un profilé 1 utilisable notamment dans le domaine de la construction. Ce profilé 1 affecte de préférence la forme d'une lame pleine ou creuse, comme illustré à la figure 2. Ce profilé 1 peut être utilisé notamment pour la réalisation de lames de bardage, de lames de revêtement de sol, de lames de volet, de lames de clôture, de portail ou autre.As mentioned above, the subject of the invention is a section 1 which can be used in particular in the field of construction. This section 1 preferably has the shape of a solid or hollow blade, as shown in Figure 2. This section 1 can be used in particular for the production of cladding blades, floor covering blades, shutter blades, fence, gate or other slats.
Comme mentionné ci-dessus, ce profilé 1 comprend un corps 2 et un revêtement 3 dudit corps 2. Le corps 2 est généralement une pièce extrudée, c'est-à-dire une pièce issue d'une fabrication par extrusion dans laquelle l'âme 21 et la peau 22 du corps 2 sont de préférence coextrudées. L'âme 21 et la peau 22 comprennent au moins du polychlorure de vinyle (PVC). L'âme 21 peut être réalisée à partir de matière de synthèse d'origine quelconque, en particulier de matière de synthèse recyclée. Le PVC de l'âme 21 utilisé peut donc être un PVC recyclé. Si nécessaire, le polychlorure de vinyle de l'âme 21 du corps 2 est un polychlorure de vinyle expansé, l'expansion s'opérant au cours de la fabrication du corps 2 du profilé 1. En variante ou en complément, l'âme 21 du corps 2 peut être une âme composite contenant, en sus du liant 211 formé par le polychlorure de vinyle, au moins une charge 212. En cas de présence de charge 212 dans l'âme 21, cette charge peut comprendre des fibres d'anas de lin. Cette fibre d'anas de lin peut se présenter sous forme de fibres ou de farine.As mentioned above, this profile 1 comprises a body 2 and a coating 3 of said body 2. The body 2 is generally an extruded part, that is to say a part resulting from manufacture by extrusion in which the core 21 and skin 22 of body 2 are preferably coextruded. Core 21 and skin 22 comprise at least polyvinyl chloride (PVC). The core 21 can be made from synthetic material of any origin, in particular recycled synthetic material. The PVC of the core 21 used can therefore be a recycled PVC. If necessary, the polyvinyl chloride of the core 21 of the body 2 is an expanded polyvinyl chloride, the expansion taking place during the manufacture of the body 2 of the profile 1. As a variant or in addition, the core 21 of the body 2 may be a composite core containing, in addition to the binder 211 formed by polyvinyl chloride, at least one filler 212. In the event of the presence of filler 212 in the core 21, this filler may comprise shavings fibers linen. This flax shavings fiber can be in the form of fibers or flour.
Généralement, la charge 212 représente au plus 60 % en poids du poids total de l'âme 21 du corps 2. La peau 22 est quant à elle réalisée en un PVC de couleur blanche. Par couleur blanche, on entend une teinte blanche dont les grandeurs L*, a*, b* dans l'espace chromatique L*a*b* CIE 1976, généralement dénommé CIELAB sont telles que suit :
L* compris entre 83 et 93,
a* compris entre -2 et 0, et
b* compris entre 0 et 3,
la mesure étant opérée suivant la norme ISO 18314-1 Version 2015 (F) avec des angles d'observation à 2° ou 10°, étant rappelé que les paramètres du système L*a*b* sont :
la clarté L* qui prend des valeurs entre 0 (noir) à 100 (blanc de référence) ;
le paramètre a* représente la valeur sur un axe vertrouge ;
le paramètre b* représente la valeur sur un axe bleujaune.Generally, the filler 212 represents at most 60% by weight of the total weight of the core 21 of the body 2. The skin 22 is itself made of a white PVC. By white color is meant a white tint whose magnitudes L*, a*, b* in the CIE 1976 L*a*b* chromatic space, generally referred to as CIELAB, are as follows:
L* between 83 and 93,
a* between -2 and 0, and
b* between 0 and 3,
the measurement being carried out according to standard ISO 18314-1 Version 2015 (F) with observation angles at 2° or 10°, it being recalled that the parameters of the L*a*b* system are:
the lightness L* which takes values between 0 (black) to 100 (reference white);
the parameter a* represents the value on a green axis red ;
the parameter b* represents the value on a blue axis YELLOW.
Cette peau 22 présente une épaisseur au moins égale à 0,5 mm. Dans l'exemple représenté, qui correspond à une lame de bardage, l'épaisseur de la peau 22 du corps est égale à 0,6 mm. Cette peau 22 présente donc une surface 221 externe tournée vers l'extérieur du profilé 1, en l'occurrence vers le revêtement 3 et une surface 222 interne tournée vers l'âme 21 de corps 2. La surface 221 externe de la peau 22 est une surface rugueuse. Cette surface rugueuse présente des rugosités 223 pouvant se présenter sous forme de creux et/ou de bosses. Ces rugosités 223 peuvent être réalisées par ponçage et éventuellement embossage à chaud de la peau 22 comme cela sera décrit plus en détail ci-après.This skin 22 has a thickness at least equal to 0.5 mm. In the example shown, which corresponds to a cladding blade, the thickness of the skin 22 of the body is equal to 0.6 mm. This skin 22 therefore has an outer surface 221 facing the outside of the profile 1, in this case towards the covering 3 and an inner surface 222 facing the core 21 of the body 2. The outer surface 221 of the skin 22 is a rough surface. This rough surface has roughnesses 223 which can take the form of hollows and/or bumps. These roughnesses 223 can be produced by sanding and possibly hot embossing of the skin 22 as will be described in more detail below.
Le revêtement 3 du corps 2 du profilé 1 est quant à lui un revêtement d'impression imprimé sur le corps 2. L'impression s'opère de préférence par pulvérisation du revêtement en une ou plusieurs passes. Cette impression peut être notamment réalisée par impression jet d'encre à l'aide de buses montées mobiles le long d'un emplacement servant à la réception du corps du profilé 1. Le revêtement 3 comprend quant à lui une encre 4 et un vernis 5 qui sont des composés polymérisables, en particulier des composés réticulables sous l'action d'un rayonnement UV. De préférence, l'encre 4 et le vernis 5 sont réticulables dans une même gamme de longueur d'ondes ou à une même longueur d'onde afin d'effectuer une réticulation simultanée de l'encre et du vernis sous UV. Les compositions d'encre et de vernis sont en outre compatibles chimiquement entre elles.The coating 3 of the body 2 of the profile 1 is for its part a printing coating printed on the body 2. The printing is preferably carried out by spraying the coating in one or more passes. This printing can in particular be carried out by inkjet printing using nozzles mounted to move along a location serving to receive the body of the section 1. The coating 3 comprises an ink 4 and a varnish 5 which are polymerizable compounds, in particular compounds that can be crosslinked under the action of UV radiation. Preferably, the ink 4 and the varnish 5 can be crosslinked in the same wavelength range or at the same wavelength in order to perform simultaneous crosslinking of the ink and the varnish under UV. The ink and varnish compositions are also chemically compatible with each other.
De préférence, l’encre est une encre de la famille des encres acryliques. En particulier, l’encre comprend comme constituant majoritaire un constituant de la famille des acryliques. De préférence, l'encre 4 est une encre pigmentée contenant des pigments 41 inorganiques. A titre de pigment inorganique, on peut citer le dioxyde de titane, le noir de carbone ou autre.Preferably, the ink is an ink from the family of acrylic inks. In particular, the ink comprises as major constituent a constituent of the family of acrylics. Preferably, the ink 4 is a pigmented ink containing inorganic pigments 41 . As an inorganic pigment, mention may be made of titanium dioxide, carbon black or the like.
De même, le vernis est un vernis de la famille des vernis acryliques.Similarly, the varnish is a varnish from the family of acrylic varnishes.
Le revêtement 3 se présente avant impression sous forme d'encre et de vernis dissociés. Pour permettre la fabrication d'un profilé 1, tel que décrit ci-dessus, on procède comme suit. Les matériaux constitutifs de l'âme 21 et de la peau 22 du profilé 1 sont préparés pour pouvoir chacun être extrudés en parallèle en vue de former le corps 2 du profilé 1. En sortie de filière d'extrusion, la surface 221 externe de la peau 22 du corps 2 du profilé 1 est poncée au cours du défilement du corps 2 du profilé 1 sur un convoyeur délimitant un chemin de guidage dudit corps 2 du profilé 1. Une fois le ponçage opéré, le revêtement 3 est appliqué sur le corps 2. Cette application s'opère par pulvérisation de l’encre 4 puis du vernis 5 à l'aide de buses montées mobiles le long d'un emplacement servant à la réception du corps du profilé 1. Une ou plusieurs lampes UV d'une longueur d'onde adaptée à l'encre et/ou au vernis permettent une réticulation du revêtement 3. Généralement, la durée de réticulation est très courte, de l'ordre de la seconde et s'effectue à température ambiante (15 à 25°C environ) sans nécessiter de traitement thermique après irradiation.The coating 3 is presented before printing in the form of ink and dissociated varnish. To enable the manufacture of a profile 1, as described above, the procedure is as follows. The materials constituting the core 21 and the skin 22 of the profile 1 are prepared so that they can each be extruded in parallel in order to form the body 2 of the profile 1. On leaving the extrusion die, the outer surface 221 of the skin 22 of body 2 of profile 1 is sanded during the movement of body 2 of profile 1 on a conveyor delimiting a guide path of said body 2 of profile 1. Once the sanding has been carried out, coating 3 is applied to body 2 This application takes place by spraying the ink 4 then the varnish 5 with the aid of nozzles mounted so as to move along a location serving to receive the body of the profile 1. One or more UV lamps of a length waveform adapted to the ink and/or to the varnish allow crosslinking of the coating 3. Generally, the crosslinking time is very short, of the order of a second and is carried out at room temperature (15 to 25°C approximately) without requiring heat treatment after irradiation.
Le profilé 1 obtenu présente un aspect qui, grâce à la conception du profilé 1 telle que décrite ci-dessus, est reproductible, y compris dans le cas d'utilisation de matériau recyclé ou d'origine inconnue au niveau de l'âme.The profile 1 obtained has an appearance which, thanks to the design of the profile 1 as described above, is reproducible, including in the case of the use of recycled material or material of unknown origin at the level of the core.
