Abstract
PURPOSE: An organic polyisocyanate is combined with an extremely small amount of a specific compound to give a polyisocyanurate foam with very high flame-retarding performance meeting the flame retardancy grade 2 according to JIS.
CONSTITUTION: When an organic polyisocyanate such as hexamethylene diisocyanate is made to react with a polyol, a foaming agent and other additives in the presence of an isocyanate-trimerization catalyst such as a tertiary amine to produce a urethane-modified polyisocyanurate foam, (4-isocyanatephenyl)-(4'-N- alkylchlorocarbamylphenyl)-methane of the formula is used as a part of the above organic polyisocyanate component by 0.5W10wt% based on the polyisocyanate to give the objective foam.
