FLAME RETARDANT COMPOSITIONS AND PROCESSES FOR PREPARATION THEREOF

This disclosure provides a composition comprising one or more substrate materials (e.g., polymers, rubbers, paper pulps, textiles, or polymer foams) and a flame retardant composition. The flame retardant composition includes at least one flame retardant salt (e.g., an ammonium salt of phosphoric aci...

Beschreibung
Zusammenfassung:	This disclosure provides a composition comprising one or more substrate materials (e.g., polymers, rubbers, paper pulps, textiles, or polymer foams) and a flame retardant composition. The flame retardant composition includes at least one flame retardant salt (e.g., an ammonium salt of phosphoric acid such as water soluble ammonium polyphosphate), a nitrogen-containing compound (e.g., urea), and optionally water. This disclosure also provides a process for preparing the flame retardant composition, a process for imparting flame retardancy to a substrate material, and an intumescent process for forming an insulating protective layer on a substrate. This disclosure further provides fire retardant articles and processes for preparing fire retardant articles. La présente invention concerne une composition comprenant un ou plusieurs matériau(x) de substrat (par exemple des polymères, des caoutchoucs, des pâtes à papier, des textiles ou des mousses polymères) et une composition ignifuge. La composition ignifuge comprend au moins un sel ignifuge (par exemple un sel d'ammonium d'acide phosphorique tel que du polyphosphate d'ammonium soluble dans l'eau), un composé contenant de l'azote (par exemple de l'urée) et éventuellement de l'eau. La présente invention concerne également un procédé de préparation de la composition ignifuge, un procédé pour conférer une ininflammabilité à un matériau de substrat et un procédé intumescent pour former une couche protectrice isolante sur un substrat. La présente invention concerne en outre des articles ignifuges et des procédés de préparation d'articles ignifuges.
