Definitions
- the present invention relates to an asymmetric laminated glazing unit consisting of at least two sheets of glass, one of whose sheets is a sheet of chemically quenched thin glass.
- Ble more particularly relates to a laminated glazing for use in the field of transport (automobile, helicopter, aircraft ..) including as a car windshield.
- Laminated glazing is commonly used since it has the advantage of being so-called "security glazing".
- security glazing In this type of glazing, a plastic interlayer sheet is placed between the two sheets of glass.
- asymmetric glazing in the sense that the two glass sheets constituting the glazing are of different thicknesses.
- Current developments seek in particular to reduce the weight of glazing and therefore move towards a decrease in the thickness of the glass sheets constituting them. It is however necessary that the laminated glass even lightened have a mechanical strength compatible with the desired applications.
- One of the possibilities for reinforcing the mechanical strength of the glazing consists of using at least one glass sheet which has a superficial zone in compression and a central zone in tension.
- This type of glass sheet is obtained in particular by subjecting it to a thermal or chemical quenching process.
- Chemical quenching is a process which consists in carrying out an ion exchange within the glass sheet: the superficial substitution of an ion (generally an alkaline ion such as sodium or lithium) by a larger ion ion ion ( generally another alkaline ion, such as potassium or sodium) from the surface of the glass to a depth commonly referred to as "exchange depth", can create on the surface of the glass sheet residual compressive stresses up to at a certain depth, often called “depth of compression”. This depth depends in particular on the duration of the ion exchange treatment, the temperature to which it is made and also the composition of the glass sheet. It is necessary to find a compromise between the duration and the temperature of this treatment, taking into account in particular the production constraints in the glass production lines.
- An asymmetric laminated glazing comprising a chemically toughened glass sheet is often a glazing consisting of two glass sheets of different thickness and also of different chemical composition.
- a certain curvature to the glazing and to bend the constituent glass sheets of the glazing before assembly.
- the two glass sheets are laid one on top of the other and are supported along their marginal end portions in a substantially horizontal manner by a frame or skeleton having the desired profile, that is to say the final profile of the glazing after assembly.
- the thinner, thinner glass sheet is positioned on the thicker glass sheet so that the support of the thin sheet on the thicker sheet is homogeneous over all the areas in contact.
- the two sheets of glass pass in a bending furnace. Since the two glass sheets have different chemical compositions, their behavior during this bending step is different and the risk of occurrence of residual defects or stresses can be consequently increased.
- the glazings have good chemical resistance and in particular good hydrolytic resistance. It is indeed necessary that the glass, after its manufacture, can be stored for a certain time, including batteries, while retaining the initial properties of the glazing, including its optical quality. Glass sheet compositions having, after chemical quenching, high compression stresses to a great depth and also good hydrolytic resistance are described in particular in patent EP0914298. However, the quenching times described in this document are not compatible with glazing production processes for automotive applications, which require significantly shorter chemical treatment times. On the other hand, the compositions of the glasses described in this document do not necessarily make it possible to be curved simultaneously with a sheet of soda-lime-type glass.
- the object of the invention is to propose asymmetric laminated glazings which have a high mechanical strength, a good hydrolytic resistance and whose two glass sheets constituting it are such that they can be bowed simultaneously.
- the subject of the invention is a laminated glazing unit which comprises at least a first sheet of soda-lime-type glass, a second sheet of glass of smaller thickness than the first sheet of glass, and a polymeric interlayer. between the two sheets of glass, the second sheet of glass being an aluminosilicate type glass comprising the following oxides in the ranges of weight contents defined below:
- the content of 3C1 ⁇ 2, the main forming oxide of glass is between 60.00% and 68.00% by weight. This range advantageously makes it possible to have stable compositions which have a good chemical reinforcing ability and viscosities compatible with the processes for manufacturing the usual glass sheets (float glass on molten metal bath) and with the bending processes for make sure of a bending simultaneous during the manufacture of a laminated glazing comprising a sheet of the soda-lime-calcium type.
- the content by weight of Al 2 O 3 is between 2.80 and 7.80%, which makes it possible to modify the viscosity of the glass so as to remain in viscosity ranges which makes it possible to manufacture the glasses without increasing the forming temperatures.
- Alumina also has an influence on the performances in the chemical reinforcement of the glasses.
- the oxides of sodium and potassium make it possible to maintain the melting temperatures and the viscosity of the glasses within acceptable limits.
- the simultaneous presence of these two oxides has the particular advantage of increasing the hydrolytic resistance of the glasses and the rate of interdiffusion between the sodium and potassium ions.
- the weight content of magnesium oxide varies between 4.90 and 10.10%. This oxide promotes the melting of the glass compositions and improves the viscosity at high temperatures, while contributing to the increase in the hydrolytic resistance of the glasses.
- the weight content of oxide in calcium is limited to 1% because this oxide is harmful for chemical quenching.
- the second glass sheet is reinforced by an exchange of sodium ions by potassium ions.
- the second glass sheet is reinforced by superficial ion exchange on an ion exchange depth of at least 30 ⁇ and the surface stress of the glass sheet is less than 550 MPa, preferably less than at least 600 MPa.
- This stress profile is obtained by an ion exchange treatment at a temperature below 490 ° C, for example at 460 ° C, for a period of 2 hours.
- the exchange depth is estimated by the method of weight gain. Ble is deduced from the weighting of the samples by assuming that the diffusion profile is approximated by an 'erfc' function with the convention that the exchange depth corresponds to the depth for which the potassium ion concentration is equal to that of the glass matrix at 0.5% (as described in René Gy, Ion exchange for glass strengthening, Materials Sfoience and Engineering: B, Volume 149, Issue 2, 25 March 2008, Pages 159-165).
- the thickness of the specimen is negligible compared to the dimensions of the sample tested and the weight gain Am can be related to the exchange depth e eC h by the formula
- the second glass sheet advantageously has good resistance to a hydrolytic resistance test.
- hydrolytic resistance is meant the ability of a glass to solubilize by leaching. This resistance is therefore particularly dependent on the chemical composition of the glass. Ble is evaluated by measuring the weight loss of finely ground glass powders after water attack.
- the water attack of the glass grains or "DGG test” is a method that consists of dipping 10 grams of crushed glass, whose grain size is between 360 and 400 ⁇ , in 100 ml of water brought to boiling for a period of 5 hours. After rapid cooling, the solution is filtered and a determined volume of filtrate is evaporated to dryness. The weight of the dry matter obtained makes it possible to calculate the quantity of glass dissolved in the water. The quantity of glass extracted in mg per gram of tested glass, which is noted “DGG", is thus determined. The lower the DGG value, the more resistant the glass is to hydrolysis.
- the second glass sheet of the glazing unit according to the present invention has a DGG value of less than 30 mg.
- This temperature is obtained by performing the average between the upper annealing temperature, i.e. the temperature at which the viscosity of the glass is 10 13 Poises and the softening temperature, i.e., the temperature at which the glass viscosity is 10 7.6 Poises for each of the glass sheets.
- the upper temperature of annealing corresponds to the temperature for which the viscosity of the glass is high enough that the disappearance of the stresses can be carried out completely in a predetermined time (stress relaxation time of about 15 minutes). This temperature is also sometimes called “stress relaxation temperature”.
- the measurements of this temperature are carried out conventionally according to standard NF B30-105.
- the softening temperature also sometimes referred to as "Littleton temperature” is defined as the temperature at which a glass wire with a diameter of about 0.7 mm and a length of 23.5 cm 1mm / min, under its own weight (ISO 7884-6). This temperature can be measured or calculated as explained in the publication Fluegel A. 2007, Europ. J. Glass3 ⁇ 4i. Technol. A 48 (1) 13-30.
- This small difference in temperature makes it possible to ensure that the two glass sheets of the glazing unit according to the invention can be curved simultaneously and then assembled with the polymeric interlayer, without the risk of causing defects such as optical defects in the glazing to appear. .
- the second glass sheet is an aluminosilicate type glass comprising the following oxides in the ranges of weight contents defined below: SQ> between 60.00 and 67.00%
- the first glass sheet is of the silico-soda-lime type and comprises the following oxides in the ranges of weight contents defined below:
- compositions of the first and second glass sheets mentioned above only indicate the essential constituents. Bles do not give the minor elements of the composition, such as conventionally used refining agents such as oxides of arsenic, antimony, tin, cerium, halogens or metal sulfides.
- the compositions may also contain coloring agents, such as iron oxides, cobalt oxide, chromium oxide, copper oxide, vanadium oxide, nickel oxide and selenium, which are most often required for applications in the field. of the automobile.
- the constituent glass sheets of the glazing unit according to the present invention are of different thicknesses and the first glass sheet is the thickest sheet.
- the first glass sheet has a thickness of at most 2.1 mm, preferably at most 1.6 mm.
- the second glass sheet which is thinner than the first has a thickness of at most 1.5 mm.
- this sheet has a thickness of at most 1.1 mm or even less than 1 mm.
- the second glass sheet has a thickness less than or equal to 0.7 mm.
- the thickness of the sheet is at least 50 ⁇ .
- the polymeric interlayer placed between the two glass sheets consists of one or more layers of thermoplastic material. It may especially be polyurethane, polycarbonate, polyvinyl butyral (PVB), polymethyl methacrylate (PMMA), ethylene vinyl acetate (EA) or ionomeric resin.
- the polymeric interlayer can be in the form of a multilayer film, having particular functionalities such as, for example, better acoustic, anti-UV properties.
- the polymeric interlayer comprises at least one layer of PVB.
- the thickness of the polymeric interlayer is between 50 ⁇ and 4 mm. Generally, its thickness is less than 1mm. In automotive glazing, the thickness of the polymeric interlayer is conventionally 0.76 mm. When the constituent glass sheets of the glazing are very thin, it may be advantageous to use a polymeric interlayer with a thickness greater than 1 mm or even greater than 2 or 3 mm to impart rigidity to the laminated glazing, without adding too much weight important.
- the subject of the invention is also a method for manufacturing laminated glazing according to the present invention, comprising a step of simultaneous bending of the first and second glass sheets, an ion exchange step of the second glass sheet and a step assembly of the two sheets of glass with the polymeric interlayer.
- the constituent glass sheets of the glazing unit according to the present invention may be manufactured according to various known methods, such as the process flotation (or “float”) in which the molten glass is poured onto a bath of molten tin, and the rolling process between two rolls (or “fusion draw”), wherein the molten glass overflows with a channel and comes to form a sheet by gravity, or the so-called “down-draw” process, wherein the molten glass flows down through a slot, before being stretched to the desired thickness and simultaneously cooled.
- process flotation or "float”
- fusion draw rolling process between two rolls
- the bending step of the first and second glass sheets is performed simultaneously.
- the two glass sheets are positioned one above the other in a frame or bending skeleton, the thinnest glass sheet being the one above, the farthest from the skeleton.
- the assembly is thus introduced into a bending furnace.
- the two sheets are separated by a pulverulent agent of the talc, calcite, or ceramic powder type to prevent friction and sticking of one sheet to the other.
- the bending thus produced is a forming by gravity and / or by pressing.
- the ion exchange experienced by the second glass sheet is generally accomplished by placing said sheet in a bath filled with a molten salt of the desired alkali ion.
- This exchange usually takes place at a temperature below the glass transition temperature and the bath degradation temperature, preferably at a temperature below 490 ° C.
- the duration of the ion exchange is less than 24 hours. However it is desirable that the exchange time is shorter to be compatible with the productivities of laminated glazing manufacturing processes for the automobile.
- the treatment time is for example less than or equal to 4 hours, preferably less than or equal to 2 hours.
- the temperatures and times of exchange are to be adjusted according to the composition of the glass, the thickness of the glass sheet, as well as the thickness in compression and the desired level of stress.
- the ion exchange can be advantageously followed by a heat treatment step to reduce the tension stress at the core and increase the depth in compression.
- the assembly step then consists in assembling the two sheets of glass with the thermoplastic interlayer by pressurizing in an autoclave and raising the temperature.
- the laminated glazing according to the present invention is advantageously a glazing for the automobile and in particular a windshield.
- the first silico-soda-lime type sheet and the second thinner aluminosilicate sheet are curved together before being assembled with the polymeric interlayer to form the glazing according to the present invention.
- the second leaf is the one that is above in the bending frame.
- the second sheet of glass corresponds to the inner sheet of glass, that is to say the one placed towards the interior of the passenger compartment.
- the first sheet of glass is the one that is placed outwards.
- the glass sheets can thus be assembled directly after the bending step, without requiring the inversion of the order of the glass sheets.
- Glazing according to the invention has been prepared from different glass sheets of different composition.
- the compositions of Examples 7, 8 and 9 are not in accordance with the invention.
- Glazing according to the present invention is manufactured using a first sheet of glass of the following composition, denoted F1 sheet:
- the asymmetric laminated glazings are manufactured by using a first glass sheet of the above-described silyclo-calcium composition having a thickness of 1.6 mm. , a 0.76 mm thick PVB interlayer and a second 0.55 mm thick glass sheet obtained after thinning the glass sheets whose composition is given in Table 1.
- the notation used to characterize the glazing is the following "F1 / F2.x" in which F1 specifies that it is the combination of a first sheet of composition F1 and a second sheet of composition x (where x varies from 1 to 9 and corresponds to Examples 1 to 9 given in Table 1.
- the sheet F2.1 is the second sheet of glass whose composition is that of Example 1).
