Abstract

The coating is characterized in that it is mainly formed from rolled zinc of considerably reduced thickness, most often in the form of a sheet or a strip provided with a layer of pressure-sensitive or adhesive pressure on one side, intended to be applied entirely.

Description

i-1 This invention relates to an antibacterial, antivirus coating,

  anti-fungal and anti-mold, or a coating which prevents the formation of bacteria, viruses, fungi and molds, in other words a coating which has the function of preventing and / or hindering rapid growth and multiplication

  pathogenic and saprophytic organisms.

  The coating is intended to be applied universally, in other words, to cover walls and work tables, on the one hand, and for

  cover equipment, etc., on the other hand.

  We know that we must continually fight the pollution caused by pathogenic and saprophytic organisms, particularly in environments that lend themselves to training and development.

of such pollution.

  Operating rooms, anesthesia, resuscitation and transplant departments in hospitals, as well as chemical laboratories where biological samples, especially pathogenic in nature, are handled, stored and analyzed are very prone to infection and pollution caused by organisms

pathogens and saprophytics.

  This also applies to sterilized premises used in microbiology and plant micropropagation laboratories, and also, in general, in structures where agricultural or food biotechnologies are used (climatic cells, growth rooms, laboratories

  food processing companies).

  The danger of infection caused by pathogenic and saprophytic organisms is also present, to a large extent, in environments and containers where infected objects are stored, and where such objects come into physical contact with

  people who are forced to handle them.

  These environments include in particular hospital laundromats, as well as containers for transporting laundromat. It is generally known that one can prevent such an infection and / or reduce its extent in the most

  effective by taking preventive measures.

  A well-known measure is to treat objects that may be infected with gamma rays

or ultraviolet rays.

  However, this solution has the disadvantage that it can only be practiced in a limited manner, for technical and economic reasons and for personnel safety. The most common preventive measure for small and large premises is to paint walls and ceilings with an antibacterial and anti-mold paint. In other words, paints which have the power to disinfect and prevent the multiplication of bacterial and pathogenic germs and / or the development of a disease of

  possible mold for a relatively long period.

  As a preventive measure, we can also

  apply a water resistant paint.

  These paints mentioned above have the drawbacks that in order to keep their effectiveness, they must be cleaned frequently, for example by washing painted walls, etc. It should be noted that in laboratory practice areas, and particularly in microbiology, many wastes of infected organic matter, with pathogenic germs, appear very

  easily inside and around the work area.

  These stains - generally rather thick - create a kind of protective organic coating which considerably reduces the antibacterial effect of the paint, because the paints usually used

  react insufficiently against him.

  According to another preventive measure, the walls, etc., can be covered with water-resistant tiles which, like the water-resistant paint already mentioned, are intended to be washed daily

  with detergent and disinfectant.

  The disadvantage of such tiles is that they are too expensive and that the joints are difficult to clean with a detergent, thus forming an ideal incubator for pathogenic germs and mold. The present invention therefore relates to an antibacterial, antivirus, antifungal and anti-mold coating which does not have the drawbacks mentioned above. This coating is formed mainly from rolled zinc of considerably reduced thickness, most often in the form of a sheet or a strip, provided with a film of self-adhesive and / or pressure-sensitive adhesive on a face intended to be fully applied. Due to its considerably reduced thickness and the self-adhesive layer, the zinc coating can be easily applied to all kinds of objects, and walls. Zinc has the effect that the existence and multiplication of bacteria, viruses, fungi and mold is prevented, or at least inhibited and, in most cases, they are destroyed by the presence

zinc.

  The thickness of the zinc is preferably between 0.08 and 0.1 mm. The adhesive film is preferably of an acrylic or elastomeric type, with a thickness of 0.4 to 0.6 mm. To prevent the appearance of electrostatic charges on the surface of zinc, presenting a danger in certain environments such as resuscitation rooms, an adhesive is used

electrical conductor.

  Such an adhesive coating is obtained by means

  a mixture of calibrated granules of appropriate sizes.

  Once the coating is applied according to the invention, the zinc granules allow a grounding contact between the zinc and the wall. The adhesive layer is protected by a silicon release sublayer, a removable protective paper or a silicon film which is removed during the application of the coating. It is obvious that the covering, in the form of a sheet or a strip of suitable dimensions, can be fixed immediately on surfaces to be covered, such as walls, relatively simply, either

  manually or mechanically.

  The visible surface of the rolled zinc is smooth and therefore has no incubation areas for

  bacteria, pathogens and mold.

  The smooth surface is therefore suitable for complete and very rapid cleaning and disinfection, in case

this is necessary.

  Tests, where similar bacterial solutions were brought into contact with the zinc coating and other preventive elements, have shown respectively that if a zinc coating is used, significantly fewer bacteria colonies are formed

over a predetermined period.

  The present invention is in no way limited to the embodiments described, since such a coating can be produced in all kinds of shapes and

  dimensions without departing from the scope of the invention.

  the adhesive layer can be provided with a sub -

  detachable release silicon paper layer or

silicon protection.
