Definitions
- the invention relates to obtaining, on a transparent glass substrate, a polychromic heterogeneous transparent decoration.
- Transparent thin layers sol-gel, ink
- the invention therefore aims to provide transparent glazing for automobiles, buildings, street furniture, interior decoration and household appliances with new aesthetic aspects. It has been sought to obtain several colorations in reflection by the implementation of easily industrializable processes.
- the subject of the invention is a method for manufacturing glazing with a glass substrate bearing a mineral coating which forms a discontinuous surface in discrete patterns, the substrate provided with its coating remaining transparent, in which the thickness of the mineral coating is not constant, each thickness value of the coating producing a characteristic color in reflection, said discrete patterns have locally controlled variable heights, characterized in that it comprises the deposition in discrete patterns with a thickness of between 5 and 60 ⁇ m of a liquid precursor of the mineral coating, in particular of a soil, by means of an engraved roller having cavities of different depths, calibrated locally, then a heat treatment at a temperature between 300 and 800°C for 30 s to 1 hour, in particular a thermal toughening treatment of the glass substrate.
- glass substrate here refer to a transparent sheet of polymeric material of the poly(methyl methacrylate) (PMMA), polycarbonate (PC) type or preferably of mineral glass such as soda-limestone, aluminosilicate, borosilicate, where applicable hardened, heat-tempered or chemically reinforced.
- PMMA poly(methyl methacrylate)
- PC polycarbonate
- mineral glass such as soda-limestone, aluminosilicate, borosilicate, where applicable hardened, heat-tempered or chemically reinforced.
- the continuous or flat surface has a variation without discontinuity of the thickness capable of producing, in reflection, a continuous variation of the coloring, that is to say a passage soft between different colors, a color gradient effect, without discontinuity, without "seam” (in English "seamless”).
- a zone of variation without discontinuity of the thickness of the coating is meant, within the meaning of the invention, a zone of the coating of variable thickness, in which this thickness is a continuous function in all directions of its surface. In other words, this surface has no discontinuity in coating thickness and height like, by analogy, a land surface free of any cliff, any crack and any sudden, occasional variation in height, level or altitude.
- the discontinuous surface in discrete patterns is also able to produce this color gradient effect in smooth transition: to obtain this effect, the sheet or the envelope of the discontinuous coating, obtained by connecting the vertex of all the discrete patterns, has in particular a geometry approaching as closely as possible said first shape described above, that is to say with the fewest possible pattern height irregularities: ideally no small group consisting of a few patterns discrete neighbors, and even no isolated discrete pattern, form an acute peak of said sheet or envelope.
- This second discontinuous shape of the coating surface thus makes it possible to form colored patterns with smooth transitions between different colors in reflection, by forming discrete patterns of (de)increasing heights in a regular manner over the entire surface, or on the contrary with clean transitions, clean edges, greater contrast, for example by forming discrete patterns in adjacent areas of different colors, each color corresponding to a single height of the patterns, and two adjacent areas not being separated by any patterned transition zone of intermediate heights between the heights corresponding to the two colorations.
- the geometry, the height, all the dimensions, the distribution and the density of the discrete patterns are controlled, to constitute decorative colored patterns of homogeneous color by zones of several neighboring patterns: many decorative, optical effects are thus made accessible.
- the mineral coating characteristic of the invention is easily obtained industrially.
- Another object of the invention consists of a glazing obtained by the method mentioned above, characterized in that said glass substrate is bonded to another glass substrate by means of an intermediate adhesive layer to form a laminated glazing whose one of the external surfaces consists of said mineral coating, in particular the surface intended to be in contact with the external atmosphere, in the mounting position.
- an adhesive interlayer are polyvinyl butyral (PVB), thermoplastic polyurethane (TPU), ethylene-vinyl acetate copolymer (EVA), ionomer resin, and any transparent casting resin.
- Another object of the invention which can be combined with the previous one, consists of a glazing obtained by the process mentioned above, characterized in that said glass substrate, optionally laminated, is associated with another glass substrate, optionally laminated , by means of a mounting joint maintaining the glass substrates with a spacing defining an air or gas layer, so as to form a multiple glazing unit, one of the outer surfaces of which consists of said mineral coating, in particular the surface intended to be in contact with the outside atmosphere, in the mounting position.
- Another object of the invention consists of a glazing obtained by the process mentioned above, characterized in that the variable thickness of the mineral coating is between 20 nm and 1 ⁇ m, in particular between 50 and 800 nm.
- the mineral coating is based on oxide, in particular a sol-gel coating, that is to say a coating obtained by a sol process.
- oxide in particular from titanium oxides, silicon oxides, zirconium oxides, tin oxides, zinc oxides, aluminum oxides, indium oxides and transition metal oxides.
- the transition metals are in particular copper, iron, cobalt, chromium and manganese.
- the transparent mineral coating may have a colored appearance due to the presence of pigments or metal particles, for example.
- a sol-gel process typically comprises:
- a "sol" i.e. a solution containing at least one precursor of the oxide to be deposited
- the precursor comprises in particular salts of the element whose oxide is to be deposited.
- These include organometallic compounds or even nitrates, acetates, chlorides, etc.
- organometallic compounds include alkoxides, for example tetraorthosilicate (TEOS) in the case of an oxide layer silicon or titanium tetraisopropoxide in the case of a layer of titanium oxide.
- TEOS tetraorthosilicate
- the sol may be partially aqueous. It preferably comprises an organic solvent, for example an alcohol, chosen in particular from ethanol, isopropanol, butanol and glycols or derivatives of glycols, and mixtures thereof.
- the sol may additionally contain viscosity-regulating agents, such as cellulose ethers or polyacrylates.
- the glazing comprises a said mineral coating on at least two faces of one and/or more glass substrate(s); a superposition of mineral coatings of the invention carried by at least two distinct surfaces of one or more glass substrate(s) is in particular likely to produce new colorations in reflection, and a visual effect of depth/relief.
- the glass substrate is made of colored glass, modifying the tints of Newton in reflection of the mineral coating.
- the glazing comprises a layered glass substrate. It is here referred to a stack of layers thin functional in particular, of the type obtained by magnetron-assisted sputtering, such as thermal control (antisolar, low-emissivity) or other. This stack is also likely to modify the coloring in reflection of the mineral coating of non-constant thickness, by its superposition with the latter.
- the glass substrate is made of satin or etched glass, or textured, so as to add a visual relief effect to the colored reflection of the mineral coating.
- the invention also relates to the application of a glazing described above as a rear quarter window, rear window, roof or other glazing for the automobile, facade, partition, shower screen, balcony or other glazing for the building, bus shelter or other glazing for street furniture, glazing for interior decoration, oven door or other glazing for household appliances.
- Variable thicknesses of liquid solutions marketed by the Ferro Company under the reference GSGF SILVER Lustreflex TLU0050A-MD were deposited on 3.85 mm thick sheets of soda-lime glass with a green tint (light transmission factor TL of 40%) on the one hand, of glass tinted in the mass marketed by the Saint-Gobain Glass Company under the reference VG10 (Venus Gray of 10% of TL) on the other hand.
- TLU0050 liquid solutions are precursors of reflective ceramic coatings based on titanium oxide, intended to be subjected to heat treatment on their glass substrate.
- the titanium oxide precursor is titanium tetraisopropanolate (3 to 10%), mixed with organic compounds: hexa-2,4-dienoic acid (3 to 5%), rosin (2.5 to 10%) , solvent naphtha (petroleum) heavy aromatic (1-10%), N-(2-ethylhexyl)-1-[[3-methyl-4-[(3-methylphenyl)azo]phenyl]azo]naphthalene-2-amine (0.1 to 1%) in an organic solvent (ether/glycol acetate, acid/ester/carbon dioxide, oil vegetable/terpene/balm/wax/resin, salt of organic acids/bases, carbohydrate/cellulose (derived)).
- organic solvent ether/glycol acetate, acid/ester/carbon dioxide, oil vegetable/terpene/balm/wax/resin,
- the engraved roller makes it possible to deposit in a single pass drops, points, lines, or other geometric patterns according to different local thicknesses.
- the roller cavities can be shaped like square or honeycomb pyramids.
- the cavity width is between 150 and 1500 ⁇ m, in particular of the order of 500 ⁇ m
- the cavity height is between 50 and 500 ⁇ m, in particular of the order of 150 ⁇ m.
- the cavities are present on all or part of the roller surface, depending on the area in which the patterning of the mineral coating is desired.
- the Brookfield viscosity at 20°C of the liquid precursor of the mineral coating is preferably between 10 mPa.s and 5 Pa.s.
- a thermal tempering treatment of the glass substrate will be adapted to bake and harden the titanium oxide coating, which is therefore temperable.
- This tempering treatment is carried out at 650°C for 45 s per glass thickness (approximately 180 s for 3.85 mm thickness). If a coating is deposited on both sides of a glass substrate, pre-baking at 600°C of the coating deposited first is necessary to make the sol-gel conveyable, and to print, and bake the other side.
- Thicknesses of 10-12, respectively 21 -23, respectively 32-34, respectively 43-45 ⁇ m of liquid precursor harden in thicknesses of 50- 70, respectively 1 10-130, respectively 170-190, respectively 230- 250 nm of dry titanium oxide, reflecting in silver, respectively golden, respectively pink-red, respectively bluish hues. These tints in reflection are more sustained and contrasted on glass tinted throughout with 10% TL than on glass with a green tint and 40% TL
