Definitions
- the invention relates to insulation materials suitable for handicrafts for insulation against the effects of temperature, sound and / or moisture in construction with at least one insulation layer which contains inorganic and / or organic insulation materials, a method for producing the same and a method for avoiding the dusting of mineral fiber insulation materials.
- inorganic fibrous insulating materials such as rock or slag wool
- inorganic fibrous insulating materials such as rock or slag wool
- the severity and progression depends on the type, amount and size of the fibroplastic irritant effect of the particles as well as on the duration of exposure and the individual resistance of the personnel laying the conventional insulation materials.
- the consequence of continual inhalation of these Particles or particles can be pneumoconiosis when working with conventional mineral fiber insulation materials for many years.
- the PCT / SE94 / 00750 proposes to bind the particles or the dust that is conventionally released in the mineral wool by simultaneously bringing the fibers into contact with a mixture of a binding oil and a binding agent during the production of the fibers are, wherein the mixture also contains an emulsifying agent, which facilitates and stabilizes the distribution of the binding oil in the binder.
- this method is costly simply because of the need to precisely control the addition of the mixture during fiber production because of the additional equipment required in production.
- this method makes it necessary to ensure that each fiber must be brought into contact with the mixture in order to prevent the release of external fibers from the fiber fabric from the outer layer and their subsequent release.
- the use of the mixture makes it difficult to dispose of these insulating materials, since they have to contain additional chemicals such as emulsifying agents, binding oil and binding agents.
- EP-A 0 375 235 and EP-A 0 303 165 also tries to prevent the dusting behavior of the mineral fibers from insulation boards by spraying them with an aqueous dispersion of a binder in the hot state during the manufacturing process and then spraying them dried at elevated temperature, the binder containing a gelatinized starch sulfamate compound and a hydrophobizing agent.
- This method also requires precise monitoring of the production of the mineral fiber composition, since it is understandable that essentially all of the fibers of the mineral fiber insulation materials are to be brought into contact with the aqueous dispersion in order to avoid the dusting of fibers, especially from the outer walls of the mineral fiber insulation materials.
- DE-OS 36 16454 does not continue in the matter, since an aqueous emulsion of a water-insoluble additive for insulating materials made of artificial mineral fibers is sprayed onto the insulating materials or the same is impregnated therewith, but the mineral fibers are reduced in that the fibers be sprayed with the aqueous emulsion before entering the collection chamber before pressing into sheets or felts.
- the conventional mineral insulation materials are water-repellent over their entire thickness due to the use of a hydrophobizing agent, but they are not waterproof. However, in order to avoid the fungal infestation of the insulation materials caused in particular by moisture, there is a need not for water repellency but for waterproofness.
