Definitions
- Low emissivity material comprising a layer based on silicon nitride or oxynitride and a layer based on zinc oxide and tin
- the invention relates to a material comprising a transparent substrate coated with a stack comprising a functional silver-based metal layer.
- the invention also relates to glazing comprising these materials as well as the use of such materials for manufacturing glazing.
- Functional silver-based metallic layers have advantageous electrical conduction and infrared (IR) radiation reflection properties, hence their use in so-called “solar control” glazing aimed at reducing the amount of incoming solar energy and / or in so-called “low-emissive” glazing aimed at reducing the amount of energy dissipated to the outside of a building, a vehicle or a device.
- IR infrared
- These silver layers are deposited between coatings based on dielectric materials generally comprising several dielectric layers (hereinafter
- Dielectric coatings allowing the optical properties of the stack to be adjusted. These dielectric layers also help protect the silver layer from chemical or mechanical attack.
- the invention relates very particularly to a material used to manufacture a glazing used as a component of a heating or cooling device.
- a heating device comprises an enclosure delimited by one or more walls and heating means so as to allow the enclosure to be heated to a high temperature.
- the heating devices can in particular be chosen from ovens, fireplaces, stoves, etc.
- the heating means are distinct from the stack of thin layers. Heated automotive glazing, the stack of which serves as a heating element that does not correspond to a heating device according to the invention.
- a refrigerating device comprises an enclosure delimited by one or more walls and means making it possible to cool the enclosure to a temperature below the normal temperature (20 ° C).
- the refrigerating devices can in particular be chosen from:
- the glazing used as constituent elements of a refrigerating device of the freezer type (negative cold) are generally monolithic glasses.
- the glazing used as component parts of a refrigerator-type heating or cooling device are generally multiple glazing.
- a multiple glazing comprises at least two substrates kept at a distance so as to delimit a space.
- the faces of the glazing are designated from the inside of the heater or cooler and by numbering the faces of the substrates from the inside (inner face) to the outside (outer face) of the heater or cooler.
- the different substrates are generally arranged side by side in an open space.
- the various substrates are generally interconnected so as to form an airtight cavity between two substrates.
- These glazing help maintain a set temperature inside the device while keeping the exterior surface of the glazing normally cool to the touch for the protection and comfort of users.
- Coatings comprising functional silver-based metallic layers (or silver layers) are the most effective for reducing the emissivity of glazing while preserving optical and aesthetic qualities. These coatings provide better user protection, lower energy consumption and greater comfort of use.
- This phenomenon is accentuated when these glazings are used in heating devices, especially when they are subjected to long and repeated heat treatment cycles at high temperatures in a humid environment.
- the applicant has developed a functional coating which is particularly suitable for these applications.
- This coating comprises a single functional silver-based layer protected by an undercoat and a blocking overcoat.
- the dielectric coatings surrounding the functional layer essentially consist of oxide-based layers.
- This coating is particularly suitable for refrigeration and heating device applications because it has both:
- the excellent chemical durability may be due to the nature of its dielectrics which are primarily oxides.
- the materials in order to be used in heating or cooling devices, the materials must undergo a high temperature heat treatment such as quenching.
- a high temperature heat treatment such as quenching.
- the functional coating developed by the applicant remains sensitive to overheating, both during its quenching and during its potential use in a heating device. This sensitivity to heat treatment could be due to the nature of its dielectrics, which are composed exclusively of oxides.
- the silver-based functional layer is unstable and dewets during heat treatment at elevated temperature. This dewetting is characterized by the appearance of holes in the silver layer. These holes are called dendritic because of their shape often branched. These holes in the silver layer have two very damaging consequences for the product.
- the product becomes blurry (after quenching, since the edge of the holes in the silver layer diffuses the light. Visually, this blur corresponds to the appearance of a more or less milky veil. This blur can be inhomogeneous because it can reveal defects on the surface of the glass (traces of drying, marks from glass handling suction cups, etc.).
- the product's emissivity is severely degraded by these holes. Indeed, we can show that in each hole, it is no longer the emissivity of the silver layer (3%, for example) that is to be taken into account, but that of the glass (close to 89%). Thus, if the holes represent only 1% of the area, the emissivity is already degraded by about 1.8 points, going from 3% to almost 5%.
- the solution of the invention consists in using a dielectric coating located in contact with the substrate comprising:
- a layer comprising silicon chosen from layers based on nitride or based on silicon oxynitride located directly in contact with the substrate, a layer based on zinc oxide and tin comprising at least 20% by mass of tin relative to the total mass of zinc and tin located directly in contact with the layer comprising silicon.

- the dielectric coating located in contact with the substrate can include:
- a layer based on zinc and tin oxide comprising at least 20% by mass of tin relative to the total mass of zinc and tin located directly in contact with the layer comprising silicon.

- the dielectric coating located in contact with the substrate can include:
- a layer based on zinc and tin oxide comprising at least 20% by mass of tin relative to the total mass of zinc and tin located directly in contact with the layer comprising silicon.
- the sum of the thicknesses of all the oxide-based layers present in the dielectric coating located between the substrate and the first functional metal layer and / or in one or each dielectric coating located above the first silver-based functional layer is greater than 60% of the total thickness of the dielectric coating.
- the superior resistance to heating in the presence of such a substrate contact layer sequence is not only true when quenching, but also when using in a heater.
- the use of the layer sequence according to the invention has an 8 times greater resistance to heating to a temperature of 450 ° C. than that of the same functional coating without this layer sequence.
- 8 times greater resistance is meant that the material provided with a stack according to the invention can be heated at the same temperature for a time 8 times greater than the same stack without the layer sequence according to the invention, before present the same degree of degradation.
- the applicant has discovered that there is a range of thicknesses for the layer comprising silicon to be observed so as to have an anti-blur effect and very good chemical durability.
- the advantageous effects of the invention are not obtained for thicknesses less than 3 nm or 5 nm.
- the use of the substrate contact layer sequence according to the invention makes it possible to delay the degradation of the functional coating.
- this degradation delay to be sufficient not to cause degradation:
- a minimum thickness is required for the layer comprising silicon.
- the time / temperature pair during heating becomes compatible with a transformation of the glass, such as tempering or bending, without blurring. , nor degradation of emissivity.
- the glazing comprising a functional coating without the particular layer sequence of the invention shows a haze at time and temperature parameters very close to those necessary to obtain flatness, fragmentation, and acceptable form.
- the industrial tools used for bending and / or soaking the substrates comprising functional coatings can also exhibit variability. A material must therefore be robust enough to accept these process variabilities.
- the materials of the invention have this additional strength.
- the observed degradation delay severe tens of seconds at 705 ° C is sufficient to ensure that the materials will not be degraded, regardless of the variability of the quenching process.
- the invention therefore relates to a material comprising a transparent substrate coated with a stack comprising at least one functional metal layer based on silver and at least two dielectric coatings, each dielectric coating comprising at least one dielectric layer, so that each functional metal layer is disposed between two dielectric coatings, characterized in that: the dielectric coating located in contact with the substrate comprises :
- the sum of thicknesses of all oxide-based layers present in the dielectric coating located between the substrate and the first functional metal layer and / or in each dielectric coating located above the first silver-based functional layer is greater than 50 % of the total thickness of the dielectric coating.

- a glazing comprising a material according to the invention mounted on a device, on a vehicle, in particular a motor vehicle or on a building, and
- glazing according to the invention as solar control glazing and / or low emissivity for the building or vehicles
