Patent

CA 2216017

The invention pertains to flame retardant flexible polyurethane foams prepared by reacting a polyether polyol and an organic isocyanate in the presence of a blowing agent and incorporating melamine and an effective amount of another flame retardant. The organic isocyanate comprises carbodiimide-uretonimine-modified diphenylmehtane diisocyanate and toluene diisocyanate. The polyurethane foams exceed conventional flame retardancy standards and exhibit flame spread index values of less than 25 as measured under flame test procedure

L'invention porte sur des mousses de polyuréthane flexibles et ignifuges, préparées par réaction d'un polyétherpolyol et d'un isocyanate organique, en présence d'un gonflant, et par incorporation de mélamine et d'une quantité efficace d'ignifugeant. L'isocyanate organique comprend du diisocyanate de diphénylméthane et du diisocyanate de toluène, modifiés par la carbodiimide-urétonimine. Les mousses de polyuréthane dépassent les normes ignifugeantes classiques et présentent un indice de propagation des flammes inférieur à 25, selon des mesures effectuées par essai de flamme.
