Definitions

  • the invention pertains to a fire resistant laminate and to a method for the manufacture thereof.
  • Fire resistance is an important property of building
  • requirements are put to materials that are used on steel constructions in a building.
  • conditions may be put on the minimal time to fire penetration or fire spread of for example 30 or 60 minutes.
  • plasterboard is often used to provide the required fire resistance.
  • plasterboard has a number of disadvantages. It is relatively heavy, and not bendable by nature. Further, the fastening and finishing after mounting is relatively labor intensive,
  • fire resistant systems have specific applications such as for example fire resistant doors built up from different materials .
  • the invention pertains to a fire resistant laminate
  • the fire resistant laminate according the invention is relatively light and still has excellent fire resistant properties. Further, it is easy to process,, it has a smooth surface, it shows little tendency to show cracks or tears, and it does not show shrinkage or elongation. Additionally it is relatively pliable, as will be discussed below, and in case of fire it shows little or no smoke development. This combination of properties makes it suitable for use in numerous applications, e.g. , in construction or building, but also in the shipbuilding industry, in aviation, and in the manufacture of fire resistant systems .

  • the fire resistant laminate comprises two coating layers comprising intumescent components. The presence of
  • intumescent components ensures that the coating layer expands upon exposure to heat, resulting in the formation of a thicker layer. It has been found that the presence of two layers with an intermediate glass fibre web results in an improved fire resistance as compared to a single layer with the same total thickness as the two layers (compare Example 1 with Comparative Example C) . It is assumed, that the mechanism behind this effect is as follows: If the fire resistant laminate according to the invention is exposed to heat, in the first instance the first layer will expand, forming a heat resistant layer. When the exposure to heat continues, the second layer will subsequently expand.
  • the degree of expansion of the laminate preferably is at least 1.05; calculated as the thickness of the expanded laminate divides by the thickness of the original laminate, more preferably at least 1,1, still more preferably at least 1,5.
  • the degree of expansion may also be higher, for example at least 2, or even at least 3.
  • one or more of the coating layers in the laminate according to the invention also comprise an endothermic component , that is, a component which upon heating follows a chemical reaction in which heat is absorbed; which results in a cooling effect occurring. It is preferred that ail. coating layers comprise an endothermic component in addition to an inturoescent component. It will be evident that the layers can comprise one or more intuinescent components, and optionally one or more endothermic components.
  • the fire resistant laminate according to the invention comprises a non-woven glass fibre web with an areal weight of 10-50 g/m2. If the glass fibre web has an areal weight of more than 50 g/m.2 f the double-expanding effect of the
  • the glass fibre web has an areal weight below 10 g/m2, the strength of the laminate will become too low. As preferred range an areal weight of 30-50 g/m2 may be mentioned.
  • the coating layers both have a layer thickness of at least 100 microns.
  • the effect of the invention will be improved when the de layer thickness is at least 200 microns, more specifically at least 350 microns.
  • the layer thickness will be not higher than 3000 microns. More

  • the layer thickness discussed above is the average layer thickness.
  • both layers may be selected independently. It is preferred for both layers to have the same thickness, because in that case a symmetric laminate is obtained, where the person applying the laminate does not have to check which side of the laminate is the "front" and which side is the "back” .
  • the same thickness is meant that the difference in thickness between the two layers is such that in use there is no difference between the effect of laminates provided with one side to the front and laminates provided, with the other side to the front, A difference in thickness of, for example, 10% or less of the total thickness of the layers may be acceptable.
  • the laminate has a total thickness of at least 0.2 mm (200 microns). At a thickness of below 0.20 mm the effect of the invention will be insufficiently obtained. It is preferred for the laminate to have a thickness of at least 0.75 mm.

  • the laminate according to the invention has an area! weight of at least 200 g/m2 , more specifically at least 600 g/m2. If the areal weight of the laminate is too low, the fire retardancy of the system decreases. In one embodiment the areal weight is at most 1500 g/m2, more specifically at most 1200 g/m.2. It may be preferred for the areal weight of the laminate to be between 600 en 1000 g/re2. It is preferred for the laminate to have a certain pliability.

De préférence, au moins une couche de revêtement comprend, en plus d'un composant intumescent, également un composant endothermique. Le stratifié résistant au feu selon l'invention combine une résistance au feu élevée avec un faible grammage, une surface lisse, une certaine flexibilité et une faible prédisposition à l'apparition de craquelures et de déchirures. L'invention porte également sur l'utilisation du stratifié dans des bâtiments et sur des procédés pour la fabrication du stratifié.
