Abstract
The present invention relates to a method for preparing a flame retardant aid, and a flame retardant resin composition including a flame retardant aid prepared by the same, wherein the method includes preparing a metal precursor solution by adding a zinc precursor and a precursor containing an M1 metal, and preparing a multi-component metal hydroxide by adding an acid or a base to the metal precursor solution to proceed with a sol-gel reaction.
Claims9
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:
- ZnxM1y(OH)z [Formula 1]
- wherein, in Formula 1 above,
- M1 is 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.
