Definitions
- the present invention relates to a glass article in which at least one of the surfaces has antimicrobial properties which are resistant to a temperature treatment, in particular to a temperature treatment with a view to their subsequent quenching.
- glass substrates with a surface with antimicrobial properties There are different types of glass substrates with a surface with antimicrobial properties and they all have at least one antimicrobial agent. This is often located on the surface of said article.
- antimicrobial agents are silver (Ag), copper (Cu) or zinc (Zn).
- a glass substrate with a known antimicrobial property in particular of the application WO2005 / 042437 A1, is obtained by diffusion of the antimicrobial agent, in particular silver (Ag), from one of the surfaces of the substrate towards the mass. substrate, to a depth of about 2 microns.
- the antimicrobial agent in particular silver (Ag)
- Another type of glass substrate known antimicrobial property comprises, on one of its surfaces, a coating or "coating” consisting of a binder and the antimicrobial agent dispersed in said binder.
- a coating or "coating” consisting of a binder and the antimicrobial agent dispersed in said binder.
- the antimicrobial properties withstand very little treatment at temperatures above 400 ° C. Indeed, because of the rapid diffusion of the Ag element at these temperatures, it progressively migrates from the surface or from an area close to the surface, where it is effective to neutralize the microbes, towards the mass of the substrate. glassware where it is no longer available to play its antimicrobial role. Such temperatures, which are typically those required to effect quenching of the glass ( ⁇ 650-700 ° C), therefore result in a drastic decrease in the antimicrobial properties of the glass that has been heat treated. However, more and more glass applications require sheets of tempered glass for safety reasons, since such a glass has increased impact resistance.
- a solution to the problem arising from the heat treatment of a glass substrate with antimicrobial properties is already known. It is a question of using a so-called "diffusion barrier" layer in order to reduce or slow the diffusion of silver into the mass of the glass and thus to preserve as much as possible the initial antimicrobial activity.
- the state of the art describes the use of such a layer which is then deposited directly on the surface of the glass, imperatively between the glass and the antimicrobial agent.
- the substrate must then comprise a second layer deposited on the barrier layer and comprising the antimicrobial agent, alone or in combination with a binder.
- Such a solution to the problem is described in particular in the international application WO2006 / 064060 A1.
- This technical solution has certain limitations. Indeed, the introduction of one or more layers on a glass substrate often leads to an alteration of the optical and / or aesthetic properties of the substrate, such as, for example, a decrease in light transmission, a change in color or an increase in the light reflection.
- this technical solution requires the consecutive deposition of at least two layers on the glass substrate, which necessarily entails additional steps in the manufacturing process, a higher cost, and so on.
- Another technical solution to the problem of diffusion of silver from the surface to the mass would be to use a higher silver concentration from the outset so that the negative effect of this diffusion on the antimicrobial activity remains insignificant or weak.
- this solution is initially unconvincing for obvious economic reasons but also for aesthetic reasons, because too much silver concentration results in a known manner unsightly yellow color of the glass.
- an objective of the invention in at least one of its embodiments, is to provide a glass substrate with antimicrobial properties whose antimicrobial properties remain stable at temperatures above 400 ° C.
- an object of the invention is to provide a glass substrate with antimicrobial properties whose antimicrobial properties remain stable to a temperature treatment for their subsequent quenching.
- Another object of the invention is to provide a glass substrate with antimicrobial properties that does not include a layer and / or does not require a layer deposition step.
- a final objective of the invention is to provide a solution to the disadvantages of the prior art that is simple, fast and economical.

- the inventors have thus demonstrated that the presence of an inorganic component in the bulk of the glass close to the surface and distributed according to a diffusion profile made it possible to block or slow down the progressive diffusion of the silver under the effect of the temperature of the surface towards the mass of the glass.
