Definitions

  • the invention relates to a method for producing flame-retardant insulating bodies from organic fibers.
  • Equipment made of insulating materials which contain organic fibers in the form of inserts, panels, mats as cladding or intermediate layers, serve as heat, cold and sound insulation in buildings.
  • fine-pored material such as foamed plastic, polystyrene and the like is increasingly used.
  • the same has the great disadvantage that it is not versatile, because the volume does not remain constant and increases significantly at high temperatures, which severely limits its use.
  • Insulation bodies made from organic and synthetic fibers with liquid and / or mineral flame retardant ingredients which are flame retardant in heat and pyrolysis are also well known, e.g. by the following patents: DE-A-3 206 218, EP-A-96 308, FR-A-426 967 and US-A-831 740.
  • FR-A-426967 (Lyxhayr; Dickinson) describes a process for producing artificial fibers (hair) from coconuts for use in mattresses and furniture.
  • coconut fibers are pulled from a bale and boiled in an alkaline solution. In doing so, they become supple.
  • the fibers are then dried and cooled. A portion of the fibers is branched off directly from the alkaline bath for bleaching in an atmosphere containing chlorine gas and then mixed in again with the other fibers.
  • the fibers can be made non-flammable in a bath containing sodium borate and ammonium sulfate.
  • the object of the application is therefore to specify a method which makes it possible to produce insulating bodies made of coconut fibers which have the necessary properties and are flame-retardant, inexpensively, simply and in an environmentally friendly manner.
  • Another advantage of the method according to the invention is that the peat bath does not have to be treated as waste, but can be marketed as a wet or dry fertilizer.
  • the insulating body consists of a fiber structure with coconut fibers as an essential component, in which the easily flammable parts, in particular wooden parts, between the fiber bundles are removed in the roasting process described below.
  • coconut fibers With the coconut fibers, other, difficultly flammable organic or inorganic fibers can also be added to the fiber structure.
  • the fiber structure also contains essential flame retardant ingredients in liquid or solid form. The latter should be made of materials that are not assigned to any of the poison classes. Borax, Epsom salt, water glass and the like are suitable, for example.
  • the ingredients are substances that prevent energy migration, extract heat from the flames and generate flammable or suffocating gases. Water-containing or hygroscopic salts are also particularly useful as ingredients.
  • the insulating body which provides heat and cold insulation, can have one or more layers. In the case of a multi-layer version, the flame retardant ingredients are embedded between fiber layers.
  • the insulating body is suitable as heat and cold protection and is suitable for a variety of other purposes, e.g. Mattress covers, upholstery items, car seats, panels that require elastic insulation. In the case of components, the insulating body provides particularly good protection against cold, heat, acoustic noise and impact sound, and is therefore extremely versatile.
  • the insulating body is manufactured as follows: Coconut fibers become a roasting process in a bog bath for a long time, at least 60 hours subjected. In this way, easily combustible wood particles are removed between the fiber bundles of the coconut fibers, at the same time an impregnation against moisture, putrefaction, decomposition is produced. In conjunction with a mechanically driven plucking machine, such as Reisswolf, which works with needles, flame-retardant ingredients such as borax, epsom salt, magnesium sulfate, water glass in solid or liquid form are added to the roasted coconut fibers. Other organic and inorganic fibers can be mixed in, and then processing into mats, sheets or the like is carried out. The flame retardant ingredients used are not assigned to any poison class.
  • the insulating body with its flame-retardant properties is also suitable as an additive to agents intended for the production of surface coverings for components.
  • the fiber structure can contain other organic fibers with the coconut fibers, such as hand, jute, sisal, ramie, kapok and flax fibers.
  • the roasting of the coconut fibers gives the fiber structure the property of absorbing and releasing moisture, which is desirable and expedient in a large number of buildings.
