Definitions
- the invention relates to new glass compositions of the soda-lime-silica type, more particularly intended for the manufacture of glazing. Although it is not limited to such applications, the invention will be more particularly described with reference to automobile glazing.
- Glazing intended for the automotive industry is subject to various requirements, in particular as regards their optical properties; these requirements are governed by regulations, for example when it comes to the light transmission of a windshield or for the sake of user comfort, for example with regard to energy transmission or else for aesthetic reasons, especially with regard to color.
- cerium oxide CeO 2 has an effect on absorption in the ultraviolet.
- the introduction of this oxide leads to a very significant additional cost of the composition due to the cost of the raw materials allowing the introduction of this oxide.
- titanium oxide TiO 2 also has an effect on absorption in the ultraviolet. If the cost of introducing TiO 2 into a glass matrix is lower than that of CeO 2 , it still remains very high. It is also known in particular from document WO94 / 1 471 6 to combine the two oxides CeO 2 and TiO 2 , again with the aim of better absorption in the ultraviolet. Such a combination does not of course limit the additional cost due to the introduction of these oxides into a glass matrix.
- a glass composition of the soda-lime-silica type intended in particular for the production of glazing comprising the following constituents, according to contents, expressed in percentages by weight, defined by the following limits: SiO 2 74 - 80%
- the matrix according to the invention rich in silica, makes it possible to limit production costs, in particular because of the raw material providing the oxide SiO 2 which is inexpensive.
- the matrices according to the invention have the advantage of having relatively low densities; the price of glass being usually established by weight, it appears that in terms of glazing, the compositions according to the invention further reduce the price of said glazing.
- the glasses obtained according to the invention have a lower refractive index than standard soda-lime type glasses and thus have a greater anti-reflection power.
- the silica content is greater than or equal to 76%.
- the viscosity of the glasses according to the invention can make it more difficult to merge according to usual methods. However, it is also possible to carry out the fusion using techniques such as those described in French patent application FR98 / 001 76.
- AI 2 O 3 oxide is used in very small quantities, because it also contributes to an increase in viscosity and a decrease in transmission in the visible.
- K 2 0 is advantageously used with contents of less than 1.5%.
- the alkaline earth oxides introduced into the glasses according to the invention have the overall effect of increasing the viscosity at high temperatures.
- the CaO content must not exceed 10% in order to keep the devitrification of the glasses within acceptable limits. That in MgO is advantageously less than 4% for similar reasons and in addition to improve the absorption properties in the infrared.
- BaO which makes it possible to increase the light transmission, can be added in the compositions according to the invention in contents of less than 4%. Indeed, BaO has a much weaker influence than MgO and CaO on the viscosity of the glass. In the context of the invention, the increase in BaO takes place essentially to the detriment of alkaline oxides, MgO and especially CaO.
- any significant increase in BaO therefore contributes to increasing the viscosity of the glass, in particular at low temperatures.
- introduction of a high percentage of BaO appreciably increases the cost of the composition and tends to reduce the hydrolytic resistance of the glass.
- the percentage of this oxide is preferably between 0.5 and 3.5% by weight.
- the glass compositions according to the invention can also comprise the oxide B 2 O 3 .
- the B 2 O 3 content then does not exceed 2% because, beyond this value, the volatilization of boron in the presence of alkaline oxides during the production of the glass can become non-negligible and can lead to corrosion refractory in the case of conventional fusion techniques.
- higher levels of B 2 O 3 adversely affect the quality of the glass.
- the total iron content is such that Fe 2 O 3 > 1%.
- Such an embodiment is particularly favorable when the desired light transmission is not too great, for example in the case of side glazing or else of automobile roofs, or even for example, when the requirements concerning the light transmission are greater by example in the case of windshield or rear glasses made with thinner lenses.
- the total iron content is such that Fe 2 O 3 ⁇ 0.6.
- the glass composition according to the invention further comprises a functional agent absorbing ultraviolet radiation such as CeO 2 , TiO 2 , WO 3 , La 2 O 3 , ... or a combination of two or several of these oxides.
- a functional agent absorbing ultraviolet radiation such as CeO 2 , TiO 2 , WO 3 , La 2 O 3 , ... or a combination of two or several of these oxides.
- CeO 2 oxide its weight content can range up to 2% and preferably up to 1.5% and is preferably between 0.3 and 0.8% by weight.
- the weight content of TiO 2 can be between 0, 1 and 2% and does not exceed preferably not 1.2%.
- WO 3 oxide can be present with weight contents of between 0.1 and 1.2%.
- the latter oxide will be preferred to the other two, since the raw materials which make it possible to introduce it into the glass composition according to the invention are more economical.
- the presence of these functional agents easily allows ultraviolet transmissions of less than
- the glass compositions can also comprise one or more coloring agents such as CoO, Se, Cr 2 O 3 , NiO.
- the glasses according to the invention may also contain up to 1% of other constituents provided by the impurities of the vitrifiable raw materials and / or due to the introduction of cullet into the vitrifiable mixture and / or originating from the use of 'refining agent (SO 3 , Cl, Sb 2 0 3 , As 2 O 3 ).
- the overall light transmission factor under illuminant A (T LA ) is greater than or equal to 70%.
- the overall light transmission factor under illuminant A (T LA ) is less than or equal to 55%, or even 35 %.
- the overall light transmission factor under illuminant A (T LA ) is less than or equal to 1 0%.
- T (log ⁇ 3.5) - T l ⁇ q > 50 ° C, Other details and advantageous characteristics will emerge below from the description of exemplary embodiments according to the invention.
- a series of glasses has been produced from compositions shown in the table below. These compositions were prepared under redox conditions, such that the redox is between 0, 1 2 and 0.28. The optical properties are measured for a light transmission equal to 71%, under a thickness of 3.85 mm for all the examples, except for No. 1 7 (table 2) for which the values are measured under a thickness of 3, 1 5 mm.
- This table also indicates the values of the following properties: • ⁇ - the overall light transmission factor under illuminant A (T LA ) between 380 and 780 nm, " ⁇ the overall energy transmission factor T E integrated between 295 and 2500 nm depending on the Parry Moon Masse 2 standard,
- compositions which have been developed and measures of their properties, the inventors have redefined compositions by modifying the contents of Fe 2 O 3 and FeO to obtain a light transmission equal to 71% for a thickness of 3.85 nm.
- compositions prepared From the compositions prepared, the inventors further defined other compositions by modifying the matrices.
- compositions prepared and those redefined from the measured results show that the invention makes it possible to obtain new glass compositions having enhanced optical properties and in particular relatively low ultraviolet transmission at reduced costs compared to known techniques.
