Definitions

  • the invention relates to an insulating material in the form of plates or tubes with a layer of expanded rubber, one main surface of which is the contact surface with an object to be insulated and an outer protective layer is adhesively bonded to the opposite main surface.
  • AI half shells for the insulation of pipes are known, which are arranged on the pipe to be insulated to form a cylindrical body enclosing this and connected to each other along their contact surfaces.
  • the half-shells can consist of an elastic material and can be coated with a vapor-deposited metal layer.
  • ribs can be provided in the longitudinal direction or in the form of a spiral or radially extending or other projections that can be made of an elastic material.
  • EP 0 220 651 B1 discloses a three-layer plate in which a closed-cell polyurethane foam plate with a density of 40 to 120 kg / m 3 is connected on both sides to an enamelled metal sheet with the aid of a contact adhesive based on polychloroprene rubber.
  • EP 0 118 013 B1 discloses a laminate made of a foam, including rubber, polyurethane or polyvinyl chloride, in which glass fibers are embedded in the form of layers parallel to its top and bottom.
  • the laminate is covered on both sides with a flame-retardant cover sheet in the form of an aluminum foil, which is also adhered by a flame-retardant adhesive layer.
  • the laminated body is designed such that the network formed by the glass fiber layers is also adhesively bonded to the aluminum foil.
  • the object on which the invention is based is to design the insulating material of the type mentioned at the outset such that, if its mechanical strength is increased without the addition of additional flame retardants, an improved flame resistance or, with the same flame protection classification, a reduction in the necessary flame retardants is achieved.
  • the protective layer consists of a mat-shaped glass fiber material which is coated on the outside with a metal or a polymer.
  • the coating is a metal, it advantageously consists of aluminum or copper. If it is a polymer, it is expediently formed by a polyurethane, polyvinyl acetate, polyvinyl chloride or an inorganic or organic silicon compound, such as silicone rubber.
  • the thickness of the coating is preferably between 0.05 to 1 mm.
  • the coating can be produced by gluing on a film or, if it is to be particularly thin, by sputtering or vapor deposition. When gluing, a flame-retardant adhesive is expediently used.
  • a glass fiber fleece is expediently suitable as the mat-shaped glass fiber material.
  • the protective layer also being able to extend overlapping a circumferential section in the region of the cut in the case of hoses cut parallel at a connection point for assembly reasons.
  • the protective layer and the layer of expanded rubber are preferably connected by means of an adhesive applied to the glass fiber material, which is provided with a flame-retardant finish.
  • the connection of the protective layer with the hoses made of expanded rubber can also be made on site during assembly.
  • the adhesive can be applied over the entire surface or in a structured manner.
  • the expanded rubber suitably consists of acrylonitrile butadiene rubber (NBR), of ethylene propylene diene rubber (EPDM), of chloroprene rubber (CR, CSM), of silicone rubbers or of mixtures of acrylonitrile butadene rubber with polyvinyl chloride ,
  • the insulating material achieves surprisingly high values for the fire protection class with at the same time significantly improved mechanical strength without the use of halogen-containing flame retardants, which would lead to the generation of toxic gases in the event of fire.
  • the usual Chen maintain thermal insulation properties.
  • cheaper rubber or a reduced amount of chemical flame retardants can be used compared to conventional insulation materials.
  • an insulating material consisting of a layer of expanded rubber which is adhesively bonded on one side to a protective layer, for example in the form of an aluminum foil, by means of a flame-retardant adhesive, on the side of the aluminum foil under predetermined test conditions of an open flame or exposed to a strong heat source, a high proportion of the heat is reflected by the aluminum, but due to the high thermal conductivity of the aluminum, the heat is only very quickly acted on by the flame-retardant adhesive, which acts on the rubber, the temperature of which increases immediately, so that it increases begins to decompose and then catch fire. After the respective national flame test, the insulating material is then classified in France as M2, in Germany as B2 and in England as Class 1 (BS 476: Part 7).
  • the glass fiber material ensures that those prescribed for the fire classification Test conditions for the fact that the heat transfer to the rubber is delayed for a surprisingly long time, so that both the time of the release of flammable gases and the time of ignition can be delayed, so that the insulating material according to the invention during the fire tests has the fire protection class Ml or Bl or Class 0 reached.
  • the hose has an incision surface 17 that extends inclined from the inside to the outside to a radial plane.
  • the protective layer is adhesively attached to the outer circumferential surface of the layer 11 by means of the adhesive 16, whereby the protective layer can overlap in the area of the incision 17 over a part of the circumference, which can be, for example, a third to a quarter of the total circumference.
  • Corresponding overlaps of the protective layer can be provided on the end faces of the insulating material in the form of a plate or in the form of a hose.
  • Examples 1 to 4 below use samples of insulating material in the form of plates.
  • the plates are arranged at a distance of 30 cm from a radiant heater with a power of 455 W, whose radiation area of 16 cm 2 is arranged parallel to the opposite plate surface.
  • An external flame with a predetermined flame pattern is assigned to the insulating material sample in such a way that gases generated by the heating of the sample clearly change the flame pattern, for example in the form of a flare.
  • the insulation material sample consists of a 25 mm thick, uncoated plate made of expanded acrylonitrile butadene rubber with a density of 50 kg / m 3 .
  • the surface facing the radiant heater begins very much decompose quickly. Due to the gas formation, the external flame already flares up after 10 s of irradiation time.
  • the insulating material sample is bonded on one side over the entire surface with a glass fiber fleece, which has a thickness between 0.2 and 0.4 mm and covers 95% of the surface of the plate due to its non-closed surface.
  • a glass fiber fleece which has a thickness between 0.2 and 0.4 mm and covers 95% of the surface of the plate due to its non-closed surface.
  • Example 2 In the insulating material sample of Example 2, a 0.15 mm thick aluminum foil is adhered to the glass fiber fleece. The external flame burns unchanged even after an exposure time of five minutes. So there is no gas formation until then.
  • Example 2 In the insulating material sample of Example 2, a 0.15 mm thick film made of polyvinyl chloride is adhered to the glass fiber fleece. After five minutes of irradiation, there is a brief flare up of the external flame at intervals of seconds, which can be interpreted as meaning that no permanent decomposition has set in yet.
  • the protective layer made of glass fiber fleece and aluminum foil according to Example 3 or of glass fiber fleece and polyvinyl foil according to Example 4 prevents decomposition or burning of the expanded acrylonitrile-butadene rubber during an unpredictably surprisingly long period of time which expanded Rubber with the protective layer thus has a very high flame resistance and is given increased strength by the protective layer.

Abstract

L'invention concerne un matériau isolant en forme de plaques ou de tuyaux, comprenant une couche en caoutchouc expansée (11) dont une face principale est la face (12) venant en contact avec un objet à isoler, et à la face principale opposée (13) de laquelle est reliée, de façon adhésive (16), une couche protectrice extérieure. En vue d'augmenter la résistance à la flamme, la couche protectrice est constituée par un matériau en fibres de verre en forme de nappe (14), enduit extérieurement d'un métal ou d'un polymère (15).
