Definitions

  • the invention relates to a heatable fire-resistant safety glazing and a method for producing a heatable fire-resistant safety glazing according to the preamble of the corresponding independent claims.
  • Heated glass or a heated glazing unit with an embedded wire can be used inter alia in cars as a heated windscreen and / or rear window and is also known for use in shipping.
  • heated glasses can provide optimum visibility on the bridge of a ship at all times by preventing fogging of the bridge glazing. In addition, they increase comfort by preventing cold from entering the glass and providing a pleasantly warm environment in the wheelhouse for the crew.
  • heatable insulating glasses are known in construction applications, which are equipped with an additional, gas-filled space between panes due to the insulating function, whereby the glazing is relatively thick.
  • Such glazings are also referred to as fire-resistant glazings or fire-resistant glazings.
  • Fire-resistant glazings are known, for example, from WO 2009/1 1 1897, in which a fire-retardant fire-protection layer based on silicon dioxide is arranged between two glass panes.
  • a fire-retardant fire-protection layer based on silicon dioxide is arranged between two glass panes.
  • such fire-resistant glazings with a fire protection layer are relatively heavy and therefore rather unfavorable, especially in maritime applications.

  • the fire resistance of a glazing in case of fire provides protection against fire, ie flames and toxic fumes. Fire conditions are standardized in EN 1363 and EN 1364.
  • the fire protection properties of a glazing can be classified according to Nonn EN 13501 (as of December 2013) for construction applications or 1MO FTP code 2010 for marine applications. For example, in the case of buildings, ie for construction applications or for marine applications, the following classes for fire-resistant glazings are distinguished:
  • Classification E room closure
  • a for marine applications specifies space-enclosing fire-resistant safety glazing, according to how long it ensures a seal against smoke and dilute gases.
  • Kunststoffabschliessend in this sense means tightness against smoke and hot gas and thus against fire.
  • Classification EI space closure & insulation
  • B for marine applications specifies space-terminating design elements, ie a fire-resistant safety glazing, by how long they meet the requirements of Class E and additionally provide insulation against heat (radiation, heat conduction) by increasing the average temperature increase on the cold side to 140 K and the maximum temperature rise on the cold side to ⁇ 180 K during the fire resistance period may not be exceeded.
  • fire protection times also called fire resistance duration or time
  • at least one fire resistance ie fire protection
  • independent of the classification must be maintained for at least 10 minutes.
  • Elements that are not at least 10 minutes raumabschliessend and thus do not meet the minimum criteria for classification, can not be referred to as fire or fire protection elements and are therefore not considered to be fire-resistant or fire retardant, fire-protective.
  • WO 2013/178369 discloses a thin-film radiator for living spaces. At the thin-film heaters no fire-resistant or fire protection requirement are made. On the contrary, the electric heater disclosed in WO 2013/178369 fulfills exclusively a heating function and, according to the definition, no fire protection function.
  • US2016 / 249414 shows a heatable windshield with an electric heating element in an adhesive film layer, similar to that shown in WO 201 1/048407.

  • Trivial combinations of heating wires and fire-resistant glazings are known, for example, from EP 1241 144.
  • From WO 2015/058885 it is known, for example, that functional coatings which are arranged between a carrier layer and a compound layer can have a specific function. The same is also known from WO 2015/15846.

Therefore, the fire safety glazing is not only heatable via the electrically conductive element but also fire-resistant, these two properties are integrated together in the heatable fire-resistant safety glazing. In other words, the electrically conductive element also allows for increased fire resistance.

For example, such standardized requirements are listed or defined in EN 13505 and allow the classification of fire protection elements.
  • the conditions of a standardized fire are defined in EN 1364 and EN 1363 (as of 2013).
  • the circumferential surface areas of the surface element between the flat sides are called end faces in the present text; the end faces can also be referred to as "edge” or "narrow side" of the surface element. In this case, the end face on a smaller area than the flat sides and an extension of the front side perpendicular to the large surfaces, ie perpendicular to the flat sides, corresponds to the thickness of the surface element.

  • an electrically conductive element 4 is arranged as an electrically conductive coating with two electrical connections.
  • the second surface element 3 is designed as a prestressed glass sheet with a prestress of 120 MPa.
  • the first surface element 2 and the second surface element 3 are interconnected by a laminating film of polyvinyl butyral (PVB) or Sentry glass plus ⁇ (SGP) or EVA or Hartz or similar composite material, wherein the electrically conductive element 4 between the first surface element 2 and the second surface element 3 is arranged.

  • the heatable glazing unit is connected via an additional laminating film 40 with an additional high-prestressed glass pane 8.
  • a heatable fire protection unit can be provided which, however, is relatively heavy and thick due to the large number of glass panes and is produced in several complex work steps.
  • FIG. 3 shows a heatable fire protection safety glazing 1 with integrated fire protection and heating function.
  • first surface element 2 On a highly biased first surface element 2, an electrically conductive element 4 is applied in the form of an electrically conductive coating.

  • the heatable fire protection safety glass 1 thus constructed is fire-resistant for at least 20 minutes in case of fire.
  • Such fire protection safety glazing 1 is relatively thin and therefore relatively easy, since it contains no additional fire protection intermediate layer or additional glass.

  • FIG. 4 shows a similar structure of a heatable, monolithic fire protection safety glazing 1 as in FIG. 3, in which the second surface element 3 is also highly prestressed and is thus designed as a highly pretensioned, first surface element 2.
  • the electrically conductive element 4 in the form of a structured electrically conductive coating is arranged between the two highly prestressed surface elements 2, 3 which are connected to one another by means of a laminating film to form a monolithic fire-resistant safety glazing 1.
  • the thickness and the weight of the heatable fire-resistant safety glass 1 can be further reduced.

Abstract

L'invention concerne un vitrage de sécurité anti-feu 1, transparent et chauffant, destiné à des applications marines, qui comprend un premier élément de surface 2 fortement précontraint et un second élément de surface 3 ainsi qu'un élément électriquement conducteur 4. Les premier et second éléments de surface 2, 3 possèdent chacun deux grandes surfaces sensiblement parallèles qui sont également désignées par faces planes. L'élément électriquement conducteur 4 est disposé sur une face plane du premier ou second élément de surface 2, 3. Le vitrage de sécurité anti-feu 1 est conçu comme un vitrage de sécurité composite monolithique et l'élément électriquement conducteur 4 est disposé entre le premier élément de surface 2 et le second élément de surface 3. En cas d'incendie, le vitrage de sécurité anti-feu 1 est apte à confiner l'espace, donc à résister au feu, au moins pendant 20 minutes. Par conséquent, le vitrage de sécurité anti-feu 1 peut non seulement être chauffé mais également résister au feu. Ces deux propriétés ne résultent pas d'une simple combinaison mais plutôt d'une intégration de la résistance au feu dans le vitrage de sécurité anti-feu chauffant.
