9 Claims

1. A flame retardant resin composition comprising:

a base resin; a halogen-based flame retardant comprising tetrabromobisphenol A, and a flame retardant aid, wherein the flame retardant aid is a multi-component metal hydroxide represented by Formula I below, and wherein the base resin comprises a conjugated diene-based graft copolymer, and a matrix copolymer, which is a copolymer of an aromatic vinyl-based monomer and a vinyl cyan-based monomer:

Zn_xM¹y(OH)_z [Formula 1]

wherein, in Formula 1 above,

M¹is one or more selected from the group consisting of Al and Sn,

x and y each represent the atomic ratio of Zn and M¹, x:y is 0.5 to 2.0:0.1 to 3.0, and 2≤z≤6,

wherein the flame retardant composition comprises 100 parts by weight of the base resin, 10 to 25 parts by weight of the halogen-based flame retardant, and 1 to 5 parts by weight of the flame retardant aid.
