Definitions
- the present invention relates to a thermoformable multilayer film based on acrylic polymer for the protection of substrates and the objects thus obtained.
- plastic body parts such as bumpers, mirrors, the hood and, increasingly, all other parts such as doors and fenders.
- These parts have the advantage of being lighter than the same steel parts, of being insensitive to corrosion and of having better mechanical properties.
- These parts are produced by injection of molten material and / or thermoforming of thermoplastic material. There is, however, a technical difficulty in knowing that it is much more difficult to paint them than steel.
- One solution consists in covering these parts with a colored film, this film being able to be mono or multilayer.
- this film is placed at the bottom of a mold and then the molten plastic material (the substrate) is injected into it, after cooling and demolding, the part coated with the colored film is obtained, this is the technique of overmolding.
- the adhesion of the film is ensured by the contact of the molten plastic with the film causing the melting of the surface of the film on the side of the injection of the molten plastic and therefore welding. It is also possible to coextrude the substrate and the colored film, lay the substrate on the colored film or else hot press the substrate on the colored film and then optionally thermoform the whole.
- the present invention relates to these films and to the substrates coated according to this technique.
- US Pat. No. 5,514,427 proposes using the so-called "solvent cast” technique for uniformly dispersing the pigments, dyes and fillers in a multilayer film.
- the solvent cast technology firstly consists in producing a liquid composition of thermoplastic polymer in a solvent containing the polymers proper, the dispersion of pigments and the additives meeting a given specification. This liquid composition is then deposited regularly on a carrier strip. The latter is brought into a drying oven in which the solvents are extracted by evaporation and in which the composition is melted to form a continuous layer. The continuous film is then wound up.
- the structure of the film comprises, going from the inside (substrate side which is made of polyolefin or acrylonitrile butadiene styrene) outwards a layer of chlorinated polyolefin, an acrylic adhesive layer and a pigmented layer based on fluorinated polymer and methacrylate d 'alkyl.
- WO 99/37479 describes a multilayer film obtained by the technique called "solvent cast” and lamination which has respectively from the inside (substrate side) to the outside an adhesive layer of the type "pressure sensitive adhesive” (or sensitive adhesive pressure), a layer of opaque pigmented fluoropolymer where the fillers have no particular orientation and a transparent layer based on fluoropolymer.
- Patent EP 949120 proposes a multilayer film constituted from the inside towards the outside of a polymer support layer (polyolefin, acrylonitrile
- butadiene styrene, polyamide, etc. a base methacrylic layer, a pigmented fluorinated layer (without particular orientation) of color and a transparent fluorinated layer, this film then being able to be overmolded by different substrates, such as polyolefins or polyamides.
- thermoformable multilayer film obtained by lamination constituted from the inside towards the outside of an adhesive layer, of a pigmented color layer where the fillers do not have any particular orientation and of a transparent layer.
- US Pat. No. 5,707,697 describes an exterior bodywork that is decorated and weatherproof.
- This piece consists of a multi film layer obtained by the technique known as "solvent cast” then lamination and a substrate.
- the structure of the film comprises from the inside to the outside a layer of chlorinated polyolefin capable of adhering to a polyolefin substrate, a layer based on fluorinated polymer of pigmented color where the fillers do not have any particular orientation and a layer of transparent fluoropolymer with a shiny appearance.
- Patent WO 9640480 describes a multilayer structure which from the inside to the outside has a reinforcing layer (of ABS type) coated by coextrusion of an adhesion primer (acrylic), then of a colored layer consisting of a PVDF-based copolymer in admixture with an acrylic and a transparent surface layer consisting of a mixture of PVDF homopolymer with an acrylic.
- Patent WO 9403337 proposes a multilayer consisting of the interior towards the exterior of a substrate, of an adhesive layer consisting of a compound compatible with the substrate, of a reinforcing layer, of a colored layer which contains pigments in an acrylic, urethane or vinyl matrix and finally a transparent layer based on PVDF and PMMA having a composition gradient.
- the reinforcement layer may consist of PBT, PET, ABS, PVC, PA, polyester, PC, polyolefin, an ethylene copolymer and an alkyl (meth) acrylate, an acrylic polymer or d 'a mixture of at least any two of these polymers.
- US Patent 5658670 describes a bilayer film obtained by coextrusion and hot pressing of a layer of PVDF or derivatives and a layer of PA, polyurethane or polyolefin modified with an amine.
- the weak point is the adhesion of the layer of fluoropolymer to the other layers.
- the prior art has therefore proposed films in which the adhesion of the layer of fluoropolymer to the other layers is greatly improved.
- thermoformable multilayer film successively comprising: • a protective layer (A), • a transparent layer (B) comprising (by weight the total being 100%) 0 to 100% of a fluoropolymer (B1) and 100 to 0% of a polymer (B2) essentially consisting of (meth) acrylate units d alkyl,
- a layer (C) based on polyamide with amino terminations • a layer (D) consisting of a polyolefin functionalized with an unsaturated carboxylic acid anhydride,
- This film is obtained by coextrusion of the different layers, the layer (A) being able to be laminated according to the usual technique of thermoplastics. This film is then used to cover different substrates, for example by injecting the substrate in the molten state onto the multilayer film placed in the bottom of an injection mold, the layer (A) of the film being placed against the wall of the mold. .
- the layer (B) consists mainly of a functionalized acrylic polymer then we could replace the layers (C) and (D) with a single layer consisting of a copolymer of ethylene and an alkyl (meth) acrylate carrying an epoxy function.

- PMMA is used in the examples and in the description, functionalized PMMA is not clearly described, and all the acrylic polymers described are presented as equivalent. It will be seen in the comparative examples of the present invention that this is not the case.
- thermoformable multilayer film successively comprising:
- a layer (B) comprising (by weight, the total being 100%) 0 to 30% of a fluoropolymer (B1) and 100 to 70% of a functionalized polymer (B2) essentially consisting of (meth) acrylate units alkyl,
