Abstract
PURPOSE: To produce polyurethane foam having improved compression strength and uniform flame-resistant properties, by a method wherein a polyol component is added to a mixt. of a polyisocyanate component and a flame-resistant compsn. consisting mainly of Al(OH)3, and then the mixt. is expanded.
CONSTITUTION: A flame-resistant compsn. consisting of 70W100wt% Al(OH)3 and 30W0wt% Sb2O3 or ZrO2 is mixed with a polyisocyanate component to produce an addition cpd. A predetermined amount of a polyol component is added to the addition cpd. The mixt. is expanded. Flame-resistant polyurethane foam having uniform incombustibility can be produced at low cost by effectively utilizing by- product Al(OH)3 which is produced in the treatment of aluminum material to form anodized aluminum.
