Definitions

  • the present invention relates to a method of making a cellular polyurethane material by reacting an organic polyisocyanate with an essentially hydroxyl terminated polyol.
  • the present invention also relates to cellular polyurethane material thus obtained which may be a soft, semi-rigid or rigid foam material.
  • Polyurethane foam materials are used in large amounts for a variety of applications. There are low or high density soft, flexible foams, semi-rigid and rigid foams. The soft, flexible foams and almost all the semi-rigid and rigid polyurethane foams are formed using blowing agents. These blowing agents usually were chlorofluorocarbons (CFC's) . The CFC's have excellent volatility, low flammability and very good thermal characteristics, but their main disadvantage is their high ozone depleting potential (ODP) . This is the reason why the CFC's are being banned from the refrigeration and cooling technology and as a polyurethane blowing agent. As an alternative alkanes, water and HCFC's have been proposed as blowing agents.
  • CFC's chlorofluorocarbons
  • ODP ozone depleting potential
  • multifunctional additive has deliberately been used, since it has also been found that the use of this multifunctional additive in polyol based polyurethane foam systems leads to a very uniform, fine pore size cellular material. The fine pores obtained lead to better insulating properties of the polyurethane foam material which at the same time has a low volume weight. Furthermore it has been found that the use of the multifunctional additive enabled the use of polyols with high functionality, but at the same time led to low viscosities of the mixtures of the polyurethane forming components. Finally, it has also surprisingly been found that the flame retardant properties of the resulting polyurethane material are appreciably improved by the use of this multifunctional additive.

L'invention se rapporte à un procédé de fabrication de matériau polyuréthane cellulaire, dans lequel un polyisocyanate organique réagit avec un polyol de polyester et/ou de polyéther essentiellement hydroxylé, en présence de 10 à 100 % en poids (avec le polyol comme référence) d'un sel alcanolamine d'acides gras polymérisés (monomère 0-80 % en poids; dimère 10-100 % en poids; trimère 0-75 % en poids) et d'un agent gonflant vaporisable, stable et inerte (de préférence dépourvu d'halogène). L'invention décrit un matériau polyuréthane cellulaire ainsi que l'utilisation d'un sel alcanolamine comme additif à fonctions multiples dans la fabrication du matériau polyuréthane cellulaire.
