Abstract

PURPOSE: To prepare the titled urethane foam attached with a flame retardant, emitting only a small amount of toxic gas when burnt, at a low cost, by immersing a polyurethane foam in a liquid containing a resin and a borate mineral followed by drying.
CONSTITUTION: A polyurethane foam having an apparent density of 14W35kg/cm3, pref. 16W30kg/cm3, is immersed in a liquid containing a composition composed of 3W30wt% of a resin and 70W97wt% of fine powder having a particle diameter of ≥250 microns and composed mainly of (pref. ≥50wt%) a borate mineral. Drying of the impregnated foam gives the titled polyurethane foam attached with 0.5W20pts.wt. of fine powder composed mainly of a resin and a borate mineral per 1pt.wt. of the polyurethane foam.
