Definitions

  • the present invention relates to a fire protection material comprising a flat supporting material with a large number of through-openings and a fire prevention coating, which, when subjected to excessive heat, forms an insulating layer, the through-openings being closed off by.the insulating layer as it foams up.
  • the invention furthermore, relates to a process for protecting objects from the effects of fire, a construction for fire protection, as well as the use of the fire protection material for protecting objects from the effects of fire.
  • Certain fire protection materials are used in order to protect objects which are to be protected in the event of a fire against destruction by heat or fire for a certain period of time.
  • the respective regulations partly described by law, require fire protection or prevention in the sense of different durations, the need existing for a fire preventing effect which lasts as long as possible.
  • the period of time was 10 or 20 minutes assuming tests under ASTM Standard E119 or equivalent international standard.
  • the present invention is based on the task of finding a fire protection material for objects which is greatly superior to the fire protection or fire prevention obtained through known fire prevention lattices, and can be manufactured and installed in a simple manner.
  • the object of the present invention is a fire protection material, comprising a flat supporting material with a large number Qf through-openings and a fire prevention coating which forms an insulating layer such that the through-openings are closed off in the event of a fire by the insulating layer as it foams up, whrein
  • the supporting material (calculated without the through-openings) has a density of 0.01 to 3 g/cc.
  • the supporting material is preferably open-pored material, as defined blow. Glazed material offering good surface adhesion would also be acceptable.
  • the fire protection material of the invention is preferably a single layer.
  • an object of the present invention to provide a process for the protection of objects against the effects of fire by enveloping the objects, wherein at least 10% of the enveloping material consists of the fire protection material described above.
  • the invention also relates to a construction for protecting objects against fires, comprising an enveloping material arranged at a distance from the objects to be protected against fire, wherein at least 10% of this enveloping material constitutes the fire protection material described above.
  • the invention relates to the use of the above- defined fire protection material for the protection of objects, especially electrical cables and/or lines against the effects of fire.
  • the inventive fire protection material differs from the known fire protection materials essentially in respect to the following properties:
  • a fire protection effect can be achieved with the inventive fire protection material, which previously was regarded as impossible.
  • the fire protection effect can be measured, for example, according to the international standard ISO No. 834 or according to the American standard ASTM E 119 or according to the German standard DIN 4102. According to all of these standards, the temperature curves for the combustion chamber are similar in these tests.
  • the inventive fire protection material has a fire protection effect of more than 45 minutes and fire protection effects of more than 1 hour and even 3 hours are achievable. Fire protection effects such as these were previously considered to be impossible.for.fire protection materials which permit the circulation of air.
  • the supporting material comprises non-metallic, non-combustible, inorganic, heat-stable and, preferably, open-pored material.
  • examples of such materials are: lime (magnesium silicates), kaolin (aluminium silicates), clays (aluminium silicates), asbestos (magnesium silicates) and the like. So-called “ceramic” materials are preferred.
  • the supporting material may also be a flexible material or a material which can be rolled up, whose external appearance is similar to that of a (wool) blanket.
  • the fibers of such a flexible supporting material are, of course, formed from inorganic, heat-stable material. Examples of this are mineral wool, for example, rock wool with a sufficiently high melting point, fibrous aluminium silicates or other ceramic materials, plaster fibers, glass fibers with a sufficiently high melting point, and the like.
  • the supporting material can, therefore, be rigid or flexible. It is essential, however, that the supporting material has the through-openings, defined in detail above.
  • Such materials are commercially available, for example, the panels sold under the registered trademark of KAOWOOL or the blankets of Babcock & Wilcox or the products of the Carborundum Company, sold under the registered trademark of FIBERFRAX.
  • Rock wool panels Q r blankets are sold under the registered trademark of ROCKWOOL or ISOVER.
  • the through-openings can be produced in any manner desirable. For example, it is possible to produce the through-openings by drilling.
  • the shape of the cross section of the through-openings is not of particular importance. Circular through-openings, that is drill holes, are advisable, because they can readily be produced mechanically.
  • the through-openings may, however, also have any other geometric cross sectional shapes.
  • the fire prevention agents for the fire protection material of the invention have a composition which, as such, is known and is used generally for fire prevention coatings. Examples of such agents may be found in the U.S.Patent 4,292, 358. Some examples are given in the following:
  • the through-openings are labelled 1..
  • the supporting material itself is labelled 2.
  • the dotted areas 3 in Fig. 4 are intended to indicate the fire protection agent, which has penetrated into the surface of the preferred open-pored supporting material 2.
  • Fig. 5 shows the fire protection material after the fire.
  • the openings 1 are filled up with the carbon foam 4 of the fire protection agent; the same is true for the surface of the supporting material 2.
  • the invention is described in greater detail by means of the following example:
  • the drill holes were distributed essentially uniformly over the whole of the surface. The distance between the centers of the individual drill holes was approximately 25 mm. There were about 30 to 40 of these drill holes in a 100 cm 2 of the panel. This corresponds to a total surface area of the drill holes of about 10%, based on the total surface area of the panel.
  • This panel was mounted on cable trays, which were otherwise protected on three sides against fire (e.g., by massive walls or other methods).
  • the fourth side was, therefore, covered by the inventive fire protection panel and brought about adequate circulation of air. It is, of course, also possible to surround two, three or even all four sides of the cable lines completely or partly with the inventive fire protection panel.
  • the invention involves fire protection material comprising a flat supporting material with a large number of through-openings and a coating of a fire protection agent, which forms an insulating layer, the through-openings being closed in the event of a fire by the insulating layer as it foams up.
  • the supporting material comprises non-metallic, non-combustible inorganic, heat-stable, preferably open pored material, at least 3 mm thick, which has through-openings in each case of 2 mm to 1 00 mm 2 which constitute 2 to 30% of the total surface area of the supporting material.
  • the supporting material preferably has a relatively low density.
  • the invention also relates to a process for protecting objects against the effects of fire by enveloping the objects completely or partly with the fire protection material, to a construction for fire protection, obtained according to this process, as well as to the use of fire protection materials for protecting objects against the action of fire.
