Abstract

PURPOSE: A polyurethane foam having excellent resistance to heat and fire, which is useful as a construction material such as a heat-insulating material, having dispersed a mixed salt filler obtained by the reaction of borax with sulfuric acid or a filler obtained by impregnating porous aggregate with the mixed salt filler.
CONSTITUTION: As shown in the reaction formula, borax, sulfuric acid and water are reacted to obtain a mixed salt of a Glauber's salt and boric acid. The mixed salt is pulverized to obtain a mixed salt filler. Porous aggregate such as perlite or "shirasu" balloons is added to the reaction mixture while the reaction mixture is still liquid, thereby to impregnate the porous aggregate with the liquid reaction mixture. The impregnated aggregate is dried to obtain a filler coated with the mixed salt. One hundred pts.wt. of the filler, optionally, together with inorganic porous particles e.g., perlite or inorganic powders, e.g., borax, is added to 50W300pts.wt. of a foamable polyurethane resin.
EFFECT: The filler is insoluble in water and stable.
