Abstract:
A flame retardant composition produced by incorporating a flame retardant amino condensation composition in an organic material, under reaction or mixing conditions and in an amount sufficient to reduce the combustibility of the organic material, said amino condensation composition produced by mixing and heating the following components:(A) urea, in the amount of 50 to 100 parts by weight; (B) nitrogen containing compound that condensate and/or react with isocyanic acid and/or cyanic acid, in the amount of 10 to 300 parts by weight; components A and B are mixed then heated to above the melting point of urea thereby converting the melted urea into isocyanic acid and/or cyanic acid which reacts with urea and component B thereby producing an amino condensation compound; then the following components are added and mixed (C) carbonization auxiliaries; (D) filler; thereby producing an amino condensation composition.
