Process for the preparation of rigid foams based on isocyanate |
| abstract |
A) Umsetzung eines Polyesteralkohols oder eines mindestens einen Polyesteralkoholnenthaltenden Polyolgemisches mit einem stöchiometrischen Unterschussnmindestens eines mindestens difunktionellen Isocyanats zu einem Urethangruppennund Hydroxylgruppen enthaltenden Prepolymeren, B) Umsetzung des Prepolymeren aus Schritt A) mit Polyisocyanat zum Hartschaumstoffnauf Isocyanatbasis. The invention relates to a process for the preparation of isocyanate-based rigid foams by reacting polyisocyanates with compounds which have at least two isocyanate-reactive hydrogen atoms and of which at least one is a polyester alcohol, comprising the steps A) reacting a polyester alcohol or a polyol mixture containing at least one polyester alcohol with a stoichiometric deficit of at least one at least difunctional isocyanate to give a prepolymer containing urethane groups and hydroxyl groups, B) reaction of the prepolymer from step A) with polyisocyanate to give the isocyanate-based rigid foam. |
