Definitions
- the present invention relates to the integration of a light attenuation function such as sunshade, in a glazing vehicle land, air or water, or even building.
- a function such as sun visor is usually obtained either by gluing a self-adhesive sheet (in English: "sticker") or, in a laminated glazing, by an interlayer adhesive layer of which only a part is tinted.
- An interlayer adhesive layer designates a non-structural thermoplastic polymer material bonding together structural transparent sheets of laminated glazing, glass or structural polymer material, the most common examples of which are poly (methyl methacrylate) (PMMA) and polycarbonate (PC ).
- the most frequently used interlayers are polyvinylbutyral (PVB), polyurethane (PU) and ethylene-vinyl acetate copolymer (EVA).
- structural qualifies sheets constituting a laminate, which they are able to provide mechanical properties, impact resistance, shock absorption and stress, including rigidity.
- the interlayer adhesive layers are not structural.
- a sunscreen sticker is difficult to pose: possible presence of bubbles between the substrate and the sticker, non-planar substrate of complex geometry, non-developable such as double curvature.
- the light attenuation obtained by applying a paint is accompanied by other problems: oversize, adhesion of paint, undesirable solvents ...
- the inventors have endeavored to provide a vehicle or building glazing comprising at least one sheet of transparent structural polymer material with controlled light attenuation function, transparent or opaque tinted, which is easy to manufacture and implement industrially.
- This object has been achieved by the invention which, accordingly, relates to a monolithic or laminated single or multiple glazing comprising a sheet of transparent structural polymer material tinted in the mass, characterized in that the sheet of polymer material is tinted in the mass in a non-uniform and controlled manner, transparent or opaque.
- sheet of transparent structural polymer material means a sheet capable of constituting alone a monolithic glazing, and having an elastic modulus of the order of 1500 MPa for example.
- a monolithic glazing designates a glazing unit consisting of a single transparent structural sheet, in this case in the context of the invention, made of a structural polymer material.
- a laminated glazing unit comprises at least one or more other transparent structural sheets, also made of polymeric material or mineral glass, such as soda-lime, aluminosilicate, optionally tempered thermally or chemically, all these transparent structural sheets being bonded to each other. others in a laminated block through interlayer adhesive layers.
- a glazing consisting of a single transparent structural sheet or a single laminated block is called simple glazing.
- a glazing consisting of several transparent structural sheets and / or laminated transparent blocks separated from each other two by two by a blade of air, rare gas ... dry by means of a frame of 'bracing, is called multiple glazing (double, triple ).
- the hue obtained here does not provide any extra thickness and therefore, in the case of laminated glazing, no risk of failure to deaerage, optical distortion (local default parallelism).
- the sheet of polymeric material has a variable intensity of hue in the mass over its entire surface
- the sheet of polymeric material is tinted in the mass on a part, but not all of its surface; the leaf remains, on the untinted part of its surface, transparent and colorless; the sheet of polymeric material has a plurality of sides and is mass-dyed along a peripheral band along at least one side; it may be usually one or more upper sides, generally substantially horizontal mounting position, in the case of a sun visor strip;
- the sheet of polymeric material is dyed in the mass in several different colors;
- the sheet of polymeric material has at least one degraded zone of a hue in the mass; it is a continuous gradient, having a continuous variation of light transmission in said zone; a means of realizing this characteristic will be mentioned below;
- the sheet of polymeric material is chosen from a sheet of poly (methyl methacrylate) (PMMA), polycarbonate (PC), polyurethane (PU) structural, polyamide (PA), polyester;
- PMMA poly (methyl methacrylate)
- PC polycarbonate
- PU polyurethane
- PA polyamide
- the sheet of polymeric material has a thickness of between 1 and 22 mm.
- Another subject of the invention consists of a sheet of tinted polymer material suitable for entering into the composition of a monolithic or laminated glazing unit, single or multiple as described above, characterized in that it is tinted in the mass in a non-uniform and controlled manner, transparent or opaque.
- the subject of the invention is also a method for manufacturing a single or multiple monolithic or laminated glazing unit as described above, comprising bringing into contact at least a portion of at least one of the two main surfaces of a sheet of transparent structural polymeric material with a liquid dye, for a time proportional to the desired intensity of hue in the mass.
- the placing in contact with a liquid dye is advantageously carried out by dipping (in English “dip coating”), flow (in English “flow coating”), curtain (in English “curtain coating”), inkjet or screen printing.
- the curtain technique refers to a curtain, a liquid dye strip that flows on one of the two major surfaces of the sheet of polymeric material. It should be noted that, of all the above preferred processes, only the soaking produces contacting of the two surfaces of the sheet of polymeric material with the dye.
- This process is extremely practical and simple to implement industrially; it allows to easily tint a peripheral band by not soaking the remainder of the sheet in the liquid dye bath, it also allows to dye the sheet of polymeric material in a gradient by controlling the input speed of the sheet in the bath, its duration of stay in it and then its exit speed of the dye bath.
- the liquid dye is preferably in the aqueous phase; it may contain a minor proportion of organic solvents such as alcohols, and additives such as surface tension modification agents, dispersants, etc.
- the invention further relates to the application of a monolithic or laminated glazing, single or multiple as previously described as glazing of land, air or water vehicle, or building, comprising at least one sheet of polymeric material structural transparent, with a light attenuation function such as sun visor, transparent or opaque tint.
- the sheets of poly (methyl methacrylate) (PMMA), two-stretched 5 mm thick, are dyed in the mass, sold by the Saint-Gobain Sully Company under the registered trademark Acrylex®.
- the color panel is vast. Black dye is used.
- the process chosen to create a shading gradient is vertical soaking.
- the quenching and tempering rate defines the intensity of the hue (depending on the speed of movement of the front (liquid / air)).
- the entry of the PMMA sheets into the bath and their exit from the bath is almost instantaneous.
- the hue / non-hue limit can be precisely defined (in location on the PMMA sheet).
- ⁇ bath temperature plays on the diffusion rate of the shade in the material (between 20 and 90 ° C);
- a rinsing with city water is performed for a variable time after the exit of the specimen from the dye bath.
- the intensity of the hue obtained is evaluated by measuring the light transmission (TL) using a spectrophotometer according to standard NF EN 410 latest version (April 2011).
- This test D illustrates the effect of the bath temperature (here higher) on the hue intensity (stronger).
- the face of the glazing intended to be in contact with the outside atmosphere is preserved from any contact with the dye bath. If this face belongs to the sheet of tinted polymer material, and the dipping process is employed, a masking will cover this main surface of the sheet to protect it, and only the other of the two main surfaces of the sheet. (facing the inside of the vehicle or building in the mounting position) will be in contact with the bath.
