Definitions

• 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.
• the present invention relates to a flame-retardant insulating body according to the preamble of patent claim 1, a method for producing it according to patent claim 9 and an application of the same according to patent claim 12.
• the object of the insulating body is to provide an easily producible, inexpensive protection against energy migration; at the same time, it is said to be particularly effective against acoustic noise and impact sound and to retain the elastic properties which are important for acoustic insulation.
• the insulating body consists of a fiber structure with coconut fibers as an essential component, in which the easily combustible 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 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 are roasted for a long time, at least 60 hours in a mud bath process 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.
