Definitions

  • Foams have been known for a long time and are widely used due to their low density and the associated material savings, their excellent thermal and acoustic insulation properties, their mechanical damping and their special electrical properties.
  • foams can be found in packaging, in furniture and mattresses, generally for sound and heat insulation, as buoyancy bodies in watercraft, as filter and carrier material in various industrial sectors and as structural elements in the production of layered materials, laminates, composites or foam composites.
  • adequate fire protection of the foams is necessary, as is the case in legal ones Regulations and a number of other regulations is required.
  • the foams should not contain any toxic and / or odor-causing cleavage products, as is the case, for example, when using some phosphorus compounds as flame retardants.
  • AMSU as a flame retardant in isocyanate-based foams
  • German patent application DE 2542048 The foams described there were made self-extinguishing by means of the finely ground AMSU.
  • a foam containing 19% by weight of AMSU burned for a short time after being removed from a Bunsen burner flame and then went out. At 20.9% by weight of AMSU, the foam went out immediately after being removed from the flame.
  • European patent application EP 347497 flame-retardant, polyurethane-based foams are also described in European patent application EP 347497 flame-retardant, polyurethane-based foams.
  • German patent application No. 10241855.1 describes AMSU as a flame retardant for PMI foams.
  • the smoke density test according to FAR 25.853 (c) was also passed.
  • AMSU Compared to other flame retardants, the use of AMSU has the following advantages: It is cheap and can be worked into materials inexpensively as an insoluble solid. Since it is completely non-toxic, people are not endangered neither in handling nor in processing. For the same reason, there are no additional risks when processing foams equipped with AMSU, for example due to dust. AMSU is used in large quantities as a fertilizer. The entry of small amounts of AMSU into the environment is therefore ecologically harmless. There are also no additional problems with the disposal of waste materials due to the use of foams equipped with AMSU, ie the disposal of waste materials is possible using the usual disposal methods. As an inorganic solid, AMSU is not soluble in the plastic matrix. This gives the additional great advantage over soluble flame retardants that it does not act as a plasticizer.
  • AMSU as a flame retardant
  • no foams based on PVC, blends made of PVC and PU, PEI and SAN have been described in the literature known hitherto other flame retardants has been improved.
  • the incorporation of AMSU offers the possibility of achieving very good flame protection for all of the foams mentioned.
  • the effect of ammonium sulfate is similar to that of ammonium polyphosphate. It is based on the decay of the crystalline Compound in ammonia and sulfuric acid at a higher temperature. The released sulfuric acid has a pyrolyzing effect, while the released ammonia gas dilutes the flammable gases and therefore has an extinguishing effect.
  • JP 08325574 describes combinations of flame retardants which also contain ammonium sulfate, among other things.
  • the compositions described there are suitable for casting resins.
  • Combinations of other flame retardants with ammonium polyphosphate are also deposited, for example, in patent CN 1197103.
  • Other applications described in the literature which are flame-retardant with ammonium sulfate include textile applications (Khattab, MA; Gad, AM; El-Samanoudi, AHJ Appl. Polym. Sc .: Appl. Polym. Symp. (1994), 55, 87-96; Basch, Avraham; Lewin, Menachem, Text. Res. J.
  • AMSU is used as a flame retardant for paper (JP 11228968), for wood (JP 11105011; DE 19748751; Hsieh, Tang-Chou, Tai-wan Lin Yeh Shi Yen So Pao Kao (1970), No. 188, 22 pp .; Zakl. Konserw. Drewna, Pr. Inst. Technol. Drewna (1969), 16 (3), 115-28) and for polymeric materials such as polystyrene (JP 05086254) and polyethylene, polypropylene or their copolymers (AU Vasil'ev, Yu.
