ABSTRACT:
A method of producing flameproof polyisocyanurate foams is disclosed. When the foam is produced by reacting an organic polyisocyanate with polyols as a modifying agent in the presence of an isocyanate trimerization catalyst, a blowing agent and other additives, a combination of particular low molecular weight diols with particular high molecular weight polyether polyols is used as the polyol in a special weight ratio and a special total amount per 100 parts by weight of the organic polyisocyanate in the presence of special combination of an alkali metal salt of a carboxylic acid and a tertiary amine compound as the catalyst.
