Description

UTILISATION D'UNE COMPOSITION THERMOPLASTIQUE COMME ADDITIF POUR LA COLORATION OU L'IMPRESSION DE RÉSINES THERMOPLASTIQUES APOLAIRES, USE OF A THERMOPLASTIC COMPOSITION AS ADDITIVE FOR COLORING OR PRINTING APOLAR THERMOPLASTIC RESINS,
TELLES QUE LE POLYPROPYLÈNE.SUCH AS POLYPROPYLENE.
La présente invention concerne l'utilisation d'une composition thermoplastique en tant qu'additit pour améliorer la coloration ou l'impression, notamment pour la décoration, de produits ou pièces à base de résines composées de polymères apolaires, comme par exemple le polypropylène syndiotactique ou isotactique (PP) ou le polyéthylène (PE), sans traitement préalable (traitement Corona ou flammage par exemple).The present invention relates to the use of a thermoplastic composition as an additive for improving the coloring or the printing, in particular for the decoration, of products or parts based on resins composed of apolar polymers, such as, for example, syndiotactic polypropylene. or isotactic (PP) or polyethylene (PE), without prior treatment (Corona treatment or flaming for example).
En particulier, l'invention concerne des produits, pièces et objets pouvant être tissés, injectés, compressés ou extrudés.In particular, the invention relates to products, parts and objects that can be woven, injected, compressed or extruded.
Il est connu dans l'état de la technique, que les produits ou pièces à base de résines thermoplastiques apolaires, notamment le poiypropylène, doivent être traités par des procédés comme le flammage ou le traitement corona pour créer une surface polaire.It is known in the state of the art that products or parts based on apolar thermoplastic resins, in particular polypropylene, must be treated by processes such as flaming or corona treatment to create a polar surface.
Ensuite, ces substrats peuvent être colorés ou décorés par différentes méthodesThen these substrates can be colored or decorated by different methods
(procédés d'impression divers tels que sublimation, sérigraphie, ou peinture classique).(various printing processes such as sublimation, screen printing, or conventional painting).
Sans traitement préalable, ce type de résine ne peut être teinté ou décoré durablement. Le décor n'est pas stable et ne correspond pas aux exigences liées au secteur de l'automobile par exemple (vieillissement thermique, résistance aux UV, etc.).Without prior treatment, this type of resin can not be tinted or decorated durably. The decor is not stable and does not meet the requirements related to the automotive sector for example (thermal aging, UV resistance, etc.).
Le document WO 97/47684 décrit une composition de polypropylène isotactique montrant une bonne affinité pour des colorants sous forme de dispersions, qui comprend comme additifs un mélange de copolyamides et de copolymères d'éthylène et d'acétate de vinyle (EVA) (la quantité de ce mélange qui se présente sous la forme d'un alliage macrostructuré, introduite dans la composition va jusqu'à 20% en poids); cette composition peut être extrudée sous forme de fils qui forment des tissus, qui sont facile à teinter.WO 97/47684 discloses an isotactic polypropylene composition showing a good affinity for dyes in the form of dispersions, which comprises as additives a mixture of copolyamides and copolymers of ethylene and vinyl acetate (EVA) (the amount of this mixture which is in the form of a macrostructured alloy, introduced into the composition is up to 20% by weight); this composition can be extruded into yarns which form fabrics, which are easy to tint.
Néanmoins, après vieillissement ces supports perdent une partie de leurs propriétés.Nevertheless, after aging these supports lose some of their properties.
On a maintenant découvert que l'utilisation de copolymères greffés à blocs polyamide, constitués d'un tronc en polyoléfine fonctionnelle, choisie parmi les copolymères éthylène-anhydride maléique et éthylène-(méth)acrylate d'alkyle-anhydride maléique, se présentant sous la forme d'un alliage cocontinu nanostructuré, permettait, d'améliorer significativement la fixation de colorants ou encres à la surface de produits ou pièces à base de résines apolaires comme le polypropylène atactique. L'originalité de cette invention par rapport à l'état actuel de la technique est la structure de nos alliages.It has now been found that the use of polyamide block graft copolymers consisting of a functional polyolefin trunk selected from ethylene-maleic anhydride and ethylene-alkyl (meth) acrylate-maleic anhydride copolymers, being in the form of nanostructured cocontinu alloy, allowed, to significantly improve the fixing of dyes or inks on the surface of products or parts based on non-polar resins such as atactic polypropylene. The originality of this invention compared to the current state of the art is the structure of our alloys.
La présente invention concerne donc l'utilisation d'une composition thermoplastique en tant qu'additif pour améliorer la coloration ou l'impression, notamment pour la décoration, de produits ou pièces à base de résines composées de polymères thermoplastiques apolaires, tels que le polypropylène ou le polyéthylène, caractérisée en ce que ladite composition comprend au moins un copolymère greffé à blocs polyamide, constitué d'un tronc en polyoléfine fonctionnelle, choisie parmi les copolymères éthylène-anhydride maléique et éthylène-(méth)acrylate d'alkyle- anhydride maléique, et un agent antioxydant.The present invention therefore relates to the use of a thermoplastic composition as an additive for improving the coloring or the printing, in particular for the decoration, of products or parts based on resins composed of apolar thermoplastic polymers, such as polypropylene or polyethylene, characterized in that said composition comprises at least one graft copolymer with polyamide blocks, consisting of a functional polyolefin trunk selected from ethylene-maleic anhydride and ethylene-alkyl (meth) acrylate-maleic anhydride copolymers , and an antioxidant.

De préférence, les greffons polyamide sont des homopolymères constitués de reste de caprolactame, d'acide amino-1 1-undécanoïque ou de dodecalaçtame ou des copolyamides constitués de restes choisis parmi au moins deux des monomères précédents.Preferably, the polyamide grafts are homopolymers consisting of caprolactam residue, 1-amino-1-undecanoic acid or dodecalamethyl or copolyamides consisting of residues chosen from at least two of the preceding monomers.
Toutefois tout autre type de polyamide à terminaison monoNhte peut être utilisé. En particulier, la masse molaire des greffons est comprise entre 1000 et 5000 g/mole.However any other type of polyamide with monoNhte termination can be used.
