Description

La présente invention se rapporte à des compositions pour revêtement de polymère acrylique et aux produits finis ainsi revêtus. The present invention relates to compositions for coating acrylic polymer and to finished products thus coated.

Un but de la présente invention consiste à proposer des moyens pour décorer des pièces thermoformées en polymère acrylique, par exemple polyméthacrylate de méthyle, éventuellement renforcé par du polyester, lesdits moyens étant de mise en oeuvre facile, par exemple par application au moyen d'un pistolet à peinture. An object of the present invention is to provide means for decorating thermoformed parts of acrylic polymer, for example polymethyl methacrylate, optionally reinforced with polyester, said means being easy to use, for example by application by means of a spray gun.

Le brevet américain nO 3.607.988 décrit la dispersion de 3 gO de polyméthacrylate de méthyle dans du chlorure de méthylène pour former un film sur du verre après évaporation du solvant. Le brevet américain n 3.684.553 décrit le traitement d'un objet ayant une surface essentiellement constituée en polymère thermoplastique, pour éliminer les défauts de cette surface, consistant à - exposer ladite surface à une pression partielle d'une vapeur ayant pour
effet de réduire la viscosité du copolymère, et à - absorber une quantité suffisante de vapeur dans la surface de l'objet
polymère pour réduire la viscosité de celui-ci et pour permettre au
polymère de fluer pour former une surface lisse.U.S. Patent No. 3,607,988 describes the dispersion of 3 g of polymethyl methacrylate in methylene chloride to form a film on glass after evaporation of the solvent. No. 3,684,553 describes the treatment of an object having a surface essentially made of thermoplastic polymer, to eliminate the defects of this surface, consisting in exposing said surface to a partial pressure of a vapor having
effect of reducing the viscosity of the copolymer, and - absorbing a sufficient amount of vapor in the surface of the object
polymer to reduce the viscosity thereof and to allow the
polymer to flow to form a smooth surface.

Selon un exemple, un copolymère de méthacrylate de méthyle est soumis à une pression partielle de vapeur de chlorure de méthylène à 450C. Le brevet japonais nO 74/40.867 décrit une composition adhésive pour feuilles de polyméthacrylate de méthyle, comprenant de 60 à 70 t en poids de chlorure de méthylène, 2 à 20 % en poids de méthacrylate de méthyle et de 5 à 30 % en poids de tétrahydrofuranne.According to one example, a methyl methacrylate copolymer is subjected to a partial pressure of methylene chloride vapor at 450C. Japanese Patent No. 74 / 40,867 discloses an adhesive composition for polymethyl methacrylate sheets comprising from 60 to 70% by weight of methylene chloride, 2 to 20% by weight of methyl methacrylate and from 5 to 30% by weight of tetrahydrofuran.

La présente invention a pour premier objet des compositions pour revêtement de polymère acrylique, caractérisées en ce qu'elles comprennent - de 50 à 90 gO en poids d'au moins un composé choisi- parmi le chlorure de
méthylène et le trichloréthane, - de 5 à 40 % en poids d'au moins un composé (A) choisi parmi d'une part
les composés comprenant au moins une fonction cétone ou ester carboxyli
que et ayant un point d'ébullution compris entre 1000 et 1800C, et d'autre
part les mélanges de méthanol et de nitrométhane, - de 5 à 20 % en poids d'au moins un homopolymère ou copolymère d'au moins
un acrylate ou méthacrylate d'allyle, et - de 0,1 à 3 % en poids d'au moins un agent thixotropant.The present invention firstly relates to compositions for coating acrylic polymer, characterized in that they comprise - from 50 to 90 g / w of at least one compound chosen from
methylene and trichloroethane, from 5 to 40% by weight of at least one compound (A) chosen from, on the one hand,
compounds comprising at least one ketone or carboxylic ester function
that and having a boiling point between 1000 and 1800C, and other
mixtures of methanol and nitromethane, 5 to 20% by weight of at least one homopolymer or copolymer of at least
an acrylate or allyl methacrylate, and - from 0.1 to 3% by weight of at least one thixotropic agent.

Comme composés comprenant au moins une fonction cétone ou ester utilisables dans les compositions selon l'invention on peut citer notamment la diacétone-alcool (point d'ébullition 16SOC!, la méthylisobutylcétone, l'acétate ce butyle (1260C). Les acrylates ou méthacrylates entrant dans la constitution du polymère utilisable selon l'invention sont par exemple ceux dont le groupe alkyle comprend de 1 à 10 atomes de carbone. Comme agent thixotro nuant utilisable dans les compositions selon.l'invention on peut citer notamment la silice. Selon un mode de réalisation particulier de l'invention, l'agent thixotropant peut être présent dans la composition sous forme broyée dans le composé (A).As compounds comprising at least one ketone or ester functional group which may be used in the compositions according to the invention, mention may be made especially of diacetone alcohol (boiling point 16SOC, methyl isobutyl ketone, butyl acetate (1260 ° C.).) Acrylates or methacrylates Part of the composition of the polymer which can be used according to the invention is, for example, those in which the alkyl group comprises from 1 to 10 carbon atoms As thixotropic agent which may be used in the compositions according to the invention, mention may in particular be made of silica. In a particular embodiment of the invention, the thixotropic agent may be present in the composition in milled form in the compound (A).

Lorsque.des pièces thermoformées en polymère acrylique doivent être décorées par un revêtement de couleur, les compositions selon l'inven- tion peuvent en outre comprendre de 1 à 8 % en poids d'une pâte colorante, celle-ci comprenant par exemple au moins un pigment dispersé dans un composé tel qu'un phtalate de dialkyle.  When thermoformed pieces of acrylic polymer are to be decorated with a color coating, the compositions according to the invention may further comprise from 1 to 8% by weight of a coloring paste, the latter comprising for example at least a pigment dispersed in a compound such as a dialkyl phthalate.

Les compositions selon l'invention peuvent être appliquées à des pièces en polymère acrylique, par des moyens aisés d'emploi tels qu'un pistolet à peinture, soit avant soit après thermoformage. Elles peuvent être appliquées à des pièces en polymère acrylique renforcées ou non. En cas de renforcement des pièces par un béton acrylique, par exemple selon le procédé décrit dans le brevet français nO 2.343.580, un mode de réalisation particulier de l'invention consiste à déposer, sur la pièce renforcée et revêtue d'une composition selon l'invention, une couche d'un liant polymérisable telle que par exemple une solution catalysée de polyméthacrylate de méthyle dans le méthacrylate de méthyle. En cas de renforcement des pièces de polymère acrylique par une résine polyester, aucune précaution particulière n'est souhaitable. The compositions according to the invention can be applied to acrylic polymer parts, by easy means of use such as a spray gun, either before or after thermoforming. They can be applied to acrylic polymer parts reinforced or not. In case of reinforcement of the parts by an acrylic concrete, for example according to the process described in French Patent No. 2,343,580, a particular embodiment of the invention consists in depositing, on the reinforced part and coated with a composition according to the invention, a layer of a polymerizable binder such as for example a catalyzed solution of polymethyl methacrylate in methyl methacrylate. In the case of reinforcing the acrylic polymer parts with a polyester resin, no particular precaution is desirable.

La présente invention a pour second objet des pièces en polymère acrylique revêtues d'au moins une composition telle que décrite précédemment. Par polymère acrylique au sens de la présente invention on entend un homopolymère ou copolymère solide d'au moins- un acrylate ou méthacrylate d'alkyle, le groupe alkyle ayant de 1 à 10 atomes de carbone. En particulier les pièces revêtues selon l'invention peuvent être obtenues par la technique du thermoformage. The subject of the present invention is secondly acrylic polymer parts coated with at least one composition as described above. For the purposes of the present invention, the term "acrylic polymer" means a solid homopolymer or copolymer of at least one alkyl acrylate or methacrylate, the alkyl group having from 1 to 10 carbon atoms. In particular, the coated parts according to the invention can be obtained by the thermoforming technique.

Enfin la présente invention a pour troisième objet un procédé d'obtention des pièces revêtues décrites ci-dessus, caractérisé en ce que l'on applique au moins une composition décrite précédemment à une pièce en polymère acrylique au moyen d'un pistolet à peinture. Selon un premier mode de réalisation du procédé selon l'invention, l'application de la composition est effectuée avant le thermoformage de la pièce en polymère acrylique. Selon un second mode de réalisation du procédé selon l'invention, l'application de la composition est effectuée après thermoformage de la pièce. Finally, the third subject of the present invention is a process for obtaining the coated parts described above, characterized in that at least one composition described above is applied to an acrylic polymer part by means of a spray gun. According to a first embodiment of the process according to the invention, the application of the composition is carried out before the thermoforming of the acrylic polymer part. According to a second embodiment of the process according to the invention, the application of the composition is carried out after thermoforming the part.

Les exemples ci-après sont donnés à titre illustratif et nullement limitatif de l'invention. The examples below are given by way of illustration and in no way limit the invention.
