The polyol formulation must include at least one substance which is inert with respect to isocyanates, does not deplete the ozone layer and has a boiling point below 55째 C. and a reaction product
The invention relates to flame resistant rigid foams and formulations useful for the production thereof. The polyol formulation must include at least one substance which is inert with respect to isocyanates, does not deplete the ozone layer and has a boiling point below 55째 C. and a reaction product of at least one compound with an aromatic ring, at least one aldehyde or ketone and at least one primary or secondary amine. This polyol formulation is reacted with an isocyanate, optionally with other commonly used additives, to produce rigid flame resistant foams.

What is claimed is: 1. A rigid polyurethane foam obtained by reacting a) an isocyanate group-containing component, with b) a component having a flashpoint according to DIN EN 22719 below 55째 C., comprising b1) at least one substance which is inert toward an isocyanate, does not have an ozone-destro
What is claimed is: 1. A rigid polyurethane foam obtained by reacting a) an isocyanate group-containing component, with b) a component having a flashpoint according to DIN EN 22719 below 55째 C., comprising b1) at least one substance which is inert toward an isocyanate, does not have an ozone-destroying effect, and has a boiling point below 100째 C., b2) a reaction product of at least one compound having an aromatic ring, at least one aldehyde or ketone and at least one primary or secondary amine, b3) optionally, at least one isocyanate-reactive component which contains polyester groups, b4) optionally, at least one compound which is capable of reacting with the isocyanate and does not correspond to component b2 or b3, and b5) optionally, at least one additive required for the production of a foam. 2. A polyol formulation having a flash point to DIN EN 22719 below 55째 C., comprising b1) at least one substance which is inert toward an isocyanate, does not have an ozone-destroying effect, and has a boiling point below 100째 C., b2) a reaction product of at least one compound with an aromatic ring, at least one aldehyde and/or ketone and at least one primary or secondary amine, b3) optionally, at least one isocyanate-reactive component which contains polyester groups, b4) optionally, at least one compound which is capable of reacting with the isocyanate and does not correspond to components b2 or b3, b5) optionally, one or more additives required for the production of foams. 3. The polyol formulation of claim 2 in which component b) comprises up to about 40% by weight of b1), from about 5 to about 70% by weight of b2), from about 5 to about 80% by weight of b3), and from 0 to about 60% by weight of b4). 4. The polyol formulation of claim 2 in which component b) comprises from about 3 to about 20% by weight of b1), from about 10 to about 30% by weight of b2), from about 10 to about 60% by weight of b3), and from 0 to about 25% by weight of b4).
