Halogen-free flame-retardant composition

The invention relates to a halogen-free flame - retardant composition, comprising at least (A) a ganic phosphorus compound and (B) or melamine from one of the compound of the melamine growth, or a melamine of phosphorus compound (AB) and a polymer compound, and comprises one of 2~12 carbon atoms and an 0.1~30% (weight) or (of the weight of the polymer compound) comprises an acid anhydride, or epoxy group compound. The invention further relates to a according to the invention and composite for flame - retardant composition. The functional for providing according to the flame - retardant composition of the invention is that reduces the use, a water according to the invention of the firing time of said composition, wherein the flame - retardant composition is used for polyester or polyamide.
