Definitions
- the invention relates to a mirror comprising a protective coating against chemical and mechanical attack consisting of a polymer-based film and its method of manufacture.
- a mirror usually comprises a transparent and rigid substrate on which a reflective layer has been deposited.
- the reflective layer often made of metal such as silver or aluminum tends to corrode in the ambient air due to the presence of pollutants in the atmosphere such as sulphides and chlorides and is therefore necessary to protect it to increase its life.
- one or more layers of paint are deposited on the silvering mirrors to protect them against chemical and / or external mechanical aggression.
- These paints are generally of the acrylic, alkyd, epoxy or polyurethane type. They most often contain significant amounts of inorganic or organic pigments and are usually fired in the factory at high temperatures, often above 170 ° C. In order to obtain a satisfactory quality for the desired applications, it is often necessary to also play on the cooking time.
- patent application FR 2 936 240 describes a mirror comprising a protective coating combining two types of paint that do not contain lead, one being of alkyd type and the other of polyurethane type.
- US application 2009/0220685 proposes to apply a layer of epoxy paint on the silver substrate.
- the paints are generally solvent-based, which is not without problems at the sanitary and environmental level because of emissions of volatile organic compounds or VOCs, as well as at the level of safety (risk of fires) and costs (treatment and disposal of solvents). Important problems are also encountered regarding the durability of the products during their external exposure. The reduction in the level of lead currently imposed in paints is such that their durability is strongly impacted.
- Another method of protecting the silvering layer is to laminate the mirror with a counter-glass or a metal foil, for example aluminum.
- a tie layer is generally used to facilitate the adhesion of both parties.
- EP 0882997 discloses the use of a polyether-based polyether material as a tie layer.
- a counter-glass or a metal sheet weighs the final product, makes it difficult to manipulate and transformable.
- a PVB encapsulant film with a thickness of the order of several hundred ⁇ , must be used to erase the surface asperities, which poses corrosion problems at the level of edges of the mirrors.
- the invention paves the above-mentioned problems by proposing to cover the reflective layer with an attached film comprising at least one polymer-based layer protecting against corrosion and mechanical aggression such as scratches and to retain a light and easily cuttable product.
- the mirror according to the present invention comprising a glass sheet and at least one reflecting layer, preferably metal, applied to the glass comprises an outer protective coating of the reflective layer against corrosion and mechanical aggression, consisting of an attached film , whose thickness is between 5 and 500 ⁇ , said film comprising at least one layer based on polymer.
- the reflective layer of the mirror is coated with a coating against corrosion and mechanical aggression, said coating being an added film whose thickness is between 5 and 500 ⁇ , and comprising at least one polymer-based layer.
- the added film forming the protective coating is manufactured independently of the mirror and is ready for use. The film is therefore self-supporting.
- the protective coating is called “external” since it constitutes the outer face of the mirror, in contact with the ambient air. No layer or other coating is deposited on the outer protective coating.
- the thickness of the film is that measured once the protective film is applied to the mirror.
- the reflective layer may be a layer of silver, aluminum, tin, chromium, copper or their alloys.
- the mirror may include at least one inorganic water and gas barrier layer between the reflective layer and the attached film.
- the film comprises at least one layer based on a polymer chosen from:
- polyesters such as poly (ethyleneterephthalate) or PET, poly (ethylenenaphthalate) or PEN, polyglycolic acid or PGA, polylactic acid or PLA, poly (caprolactone) or PCL, poly (ethylene adipate) or PEA, poly (butylene terephthalate) or PBT, poly (trimethylene terephthalate) or PTT, poly (hydroxyalkanoate) or PHA,
- halogenated polymers such as polyvinyl chloride or PVC, polyvinyl fluoride or PVF, polyvinylidene fluoride or PVDF, polytetrafluoroethylene or PTFE, poly (chlorotrifluoroethylene or PCTFE), perfluoroalkoxy or PFA, ethylene tetrafluoroethylene or ETFE, fluorinated ethylene propylene or FEP, poly (ethylenechlorotrifluoroethylene) or ECTFE, perfluoropolyether or PFPE, polyvinylidene chloride or PVDC, polychloroprene
- vinyl polymers such as polyvinyl acetate or PVAC, polystyrene or PS, ethylene vinyl acetate or EVA acrylic polymers such as poly (methyl methacrylate) or PMMA, ethylene-ethyl acrylate or EEA, ethylene-methyl acrylate or EMA,
- polyolefins such as polypropylene or PP, polyethylene or PE, poly (methylpentene) or PMP, polyisobutylene or PIB,
- cellulose-based polymers such as hydrates or cellulose nitrates or
- the corrosion agents are in particular water, gases such as oxygen or SO 2 and small molecules such as sulphides or chlorides. It is necessary that the protective film acts as a barrier layer to the corrosion agents. Depending on the polymer chosen from the above-mentioned list, the barrier effect on water, gases and / or small molecules will be more or less important.
- the material constituting the film may especially be characterized by a permeability to water vapor of less than 200 g / mm 2 / day, at a temperature of 25 ° C. and with a relative humidity of 95%, and a permeability to oxygen less than 100 g.mm/m 2 / day / atm, at a temperature of 23 ° C and with a relative humidity of 85%.
- the water and oxygen flow measurements are respectively performed according to ASTM F1249 and ASTM D3985.
- the variation of the permeability of the film as a function of the humidity is low.
- the adhesion of the attached film on its support can be done either by the deposition of an adhesion primer before the application of said film, either directly via the attached film.
- the attached film is directly placed on the reflecting layer or on the inorganic barrier layer when it is present, the adhesion of said film being formed by an adhesion primer covering all or part of the reflective layer or layer inorganic barrier.
- the adhesion primer used may be of silane type, coating, hot wax, resin, for example epoxy, paraffin, glue or any other type of material conventionally used to allow the adhesion of a polymer-based film to a substrate. substrate.
- the attached film is a multilayer film and further comprises at least one adhesion layer.
- the adhesion layer is the outer layer of the attached film which is in direct contact with the mirror, that is to say with the metal layer or with the inorganic barrier layer if present, and which allows the adhesion of the protective film on the mirror.
- the presence of an adhesion primer is optional.
- the adhesion layer makes it possible to fix the attached film on the mirror. It may especially consist of polymer and be for example polyvinyl butyral or PVB, copolymer of ethylene and vinyl acetate or EVA, polyurethane or PU, poly (methyl methacrylate) or PMMA, polyethylene or PE .
- the attached film When the attached film is of the multilayer type, it may comprise, in addition to the adhesion layer, one or more inorganic layers, to improve the barrier properties against the corrosion agents.
- the inorganic layers may be metal layers, for example aluminum, or oxide layers such as silicon oxynitrides and / or silicon oxycarbides, and also silicon nitride layers.
- the protective film may optionally consist of only one layer, and the latter may act both as a bonding layer and a barrier layer.
- the attached film may for example be a polyethylene film.
- the thickness of the film is advantageously between 10 and 200 ⁇ .
- multilayer polymeric films in which at least one layer is optically active.
- optically active it is understood that the layer modifies the nature of the transmitted light.
- the layer may for example be colored and / or opaque.
- the added film protects the reflective layer of the mirrors, without the use of solvent. As a result, fire risks and volatile organic compound (VOC) emissions problems at the factory are limited.
- the preformed films reported on the mirror are manufactured by conventional methods known to those skilled in the art.
- the sheath blowing process also called “film blowing” in English
- the flat film extrusion process also called “film casting” in English
- Blow lines used in a sheath blowing process make it possible to produce multilayer structures.
- three types of resin are used: a resin as a mechanical structure, a resin as a binder and a resin with barrier properties.
- the molten polymer feeds an annular die.
- the tube obtained at the outlet of the die is stretched longitudinally and simultaneously air is blown into the interior, which produces a biaxial stretching.
- the inflated tube is cooled until the polymer reaches its crystallization temperature and solidifies.
- the resulting film passes through a system of rollers and is laid flat before being cut.
- Flat film extrusion involves extruding a polymer in the molten state through a flat die, stretching it in the air for a short distance and cooling it rapidly on a thermostatic roll.
- the resulting film is then stabilized in contact with successive rolls and then wound. Any inorganic layers are deposited by physical vapor deposition (PVD) or chemical vapor deposition (CVD) techniques.
- the protective film may be self-adhesive or heat-adhesive.
- the invention also relates to the method of manufacturing a mirror as described above.
- the method of manufacturing a mirror according to the present invention comprises the following steps:
- Deposition of the reflective layer on the glass sheet is performed by techniques known to those skilled in the art. We can mention the techniques of vapor deposition (CVD, PVD, magnetron) or liquid. Optionally, according to the deposition technique employed, a surface preparation can be carried out.
- an adhesion primer can be applied to the reflective layer or the inorganic barrier layer if it is present.
- This adhesion primer may be of silane type, coated, hot wax, resin, for example epoxy, paraffin, glue or any other type of material conventionally used to allow adhesion of a polymer-based film on a substrate .
- the film is advantageously directly applied to the reflecting layer of the mirror.
- the film may be directly attached to an inorganic barrier layer, for example of the SiN x or SiO x type , possibly present on the reflecting layer of the mirror and deposited by conventional techniques such as CVD, PECVD (plasma assisted) or PVD (for example magnetron) as described in patent application WO 2010/001061 A2.
- an inorganic barrier layer for example of the SiN x or SiO x type , possibly present on the reflecting layer of the mirror and deposited by conventional techniques such as CVD, PECVD (plasma assisted) or PVD (for example magnetron) as described in patent application WO 2010/001061 A2.
- the adhesion primer optionally present between the reflective layer or the inorganic barrier layer and the protective film, may be applied by liquid means.
- the application of the film is performed by all the known techniques for depositing a flexible film on a rigid substrate.
- the film can be applied by a lamination process, cold or hot depending on the nature of the adhesion layer if it is present. It can also be applied by a vacuum lamination process.
- the lamination temperature is advantageously less than 200 ° C., preferably at a temperature of between 50 and 150 ° C. It is therefore possible to prepare the protective coating at temperatures below the temperatures usually used when the protective coatings are based on paint. If the film comprises a self-adhesive adhesion layer, the film adheres directly to the substrate at room temperature and does not require heat treatment.
- the application of the film is carried out in a vacuum chamber, which allows in particular to eliminate bubbles present between the mirror and the protective film.
- the problems associated with the deposition of paint layers, which for example cause the formation of bubbles, heterogeneity and complex cleaning can thus be avoided.
- the protective coating based on an added film provides excellent performance in the protection of the reflective layer against corrosion and mechanical aggression such as scratches.
- the product obtained remains light and easily transformable compared to rolled mirrors which comprise a counter-glass or a metal sheet.
- the mirrors according to the present invention can be used in the field of building, outdoors or indoors for domestic applications, as a solar mirror or in the automotive field.

This The 80 nm thick layer almost completely reflects the visible radiation and can therefore be used as a mirror.
- a multilayer film, with a total thickness of 450 ⁇ , consisting of an EVA adhesive layer with a thickness of 400 ⁇ and an ETFE barrier layer with a thickness of 50 ⁇ , cut to the dimensions of the mirror is placed between the mirror and a support against glass.
- the set is enclosed in a vacuum bag. Outside the pocket, the medium is maintained at atmospheric pressure.
- the temperature is maintained at 145 ° C for about 15 minutes, which allows the film to adhere to the mirror.
- the media is removed before cooling the system.
- the permeance of the film with respect to the water vapor, taking into account its thickness is 0.2 / m 2 / day.
- the permeance is 2000 g / m 2 / day.

- the protective film applied to the mirror described above respects the adhesion properties described in the EN ISO 2409 standard with a value of less than 2, over a value ranging from 1 to 5 in which optimal adhesion corresponds to the value 1.
- a mirror is prepared as described in Example 1.
- An adhesive film consisting of a PET film (polyethylene terephthalate) 25 mm thick and a pressure-sensitive acrylic adhesion layer ("PSA" type) of 25 m, is deposited directly on the metal layer of a silver mirror. Deposition is by lamination at room temperature using a bonding technique in the presence of water to prevent air bubbles. Corrosion tests were also performed. At the end of the test, the mirror comprising the protective film described above has in the face less than 2 pits of diameter less than 3 mm per dm 2 .
