1. A flame-retardant thermoplastic polyurethane elastomer composition comprising
a thermoplastic polyurethane elastomer, (A) a (poly)phosphate compound represented by general formula (1): wherein n represents a number of 1 to 100; X1 represents ammonia or a triazine derivative having general formula (2): wherein Z1 and Z2, which may be the same or different, each represent a group selected from the group consisting of —NR5R6 (wherein R5 and R6, which may be the same or different, each represent a hydrogen atom, a straight or branched alkyl group having 1 to 6 carbon atoms, or a methylol group), a hydroxyl group, a mercapto group, a straight or branched alkyl group having 1 to 10 carbon atoms, a straight or branched alkoxy group having 1 to 10 carbon atoms, a phenyl group, and a vinyl group;and p represents a number satisfying the relation: 0<p≦n+2;
(B) a (poly)phosphate compound represented by general formula (3): wherein r represents a number of 1 to 100; Y1 represents a diamine represented by R1R2N(CH2)mNR3R4, piperazine, or a diamine having a piperazine ring,
wherein R1, R2, R3, and R4, which may be the same or different, each represent a hydrogen atom or a straight or branched alkyl group having 1 to 5 carbon atoms; m represents an integer of 1 to 10; and q represents a number satisfying the relation: 0<q≦r+2; and (C) silicon dioxide. |
