Embodiment 1

[0033] The thermoplastic resin composition is prepared in granular form by the following steps: 20 parts by weight of tris(tribromophenyl) cyanurate as a brominated organic flame retardant and 3 parts by weight of antimony trioxide as an auxiliary flame retardant , 3 parts by weight of black colorant, 0.3 parts by weight of antioxidant, 1.5 parts by weight of lubricant and 0.1 parts by weight of anti-dripping agent are added to 100 parts by weight of base resin, mixed evenly with a Hansel mixer, and then double Extruded by a screw extruder, the base resin is composed of the following ingredients: 20wt% ABS copolymer (DP270 manufactured by LG Chemical Company), which is prepared by emulsification graft polymerization using butadiene latex with an average diameter of 0.3 μm ; 70wt% styrene-acrylonitrile copolymer, its acrylonitrile content is 25wt% and the weight average molecular weight is 120,000; and 10wt% methyl methacrylate polymer (EH910 manufactured by LG MMA), its weight a...

Embodiment 2

[0035] Except that 60% by weight of styrene-acrylonitrile copolymer and 20% by weight of methyl methacrylate polymer were used in Example 1 above, Example 2 was performed in the same manner as Example 1 above.

Abstract

Provided is a thermoplastic resin composition having excellent flame resistance, colorability, and scratch resistance, including: A) 100 parts by weight of a basic resin comprising 10 to 89 wt % of acrylonitrile-butadiene-styrene copolymer, 89 to 10 wt % of styrene-acrylonitrile copolymer, and 1 to 40 wt % of methylmethacrylate polymer; B) 1 to 30 parts by weight of bromoalkyl or bromophenyl cyanurate compounds; and C) 1 to 20 parts by weight of antimony compound, thereby, making it possible to provide the thermoplastic resin composition having excellent flame resistance, impact strength, scratch resistance, colorability, and surface hardness as synergy effects.

Description

[0001] Cross references to related applications [0002] This application claims the right to Korean Patent Application No. 10-2008-0091500 filed with the Korean Intellectual Property Office on September 18, 2008, the entire content of which is incorporated herein by reference. Technical field [0003] The present invention relates to a thermoplastic resin composition having excellent flame retardancy, colorability, and scratch resistance. More specifically, the present invention relates to a combination of methyl methacrylate polymer, bromoalkyl or bromophenyl cyanuric acid A thermoplastic resin with an ester compound and an antimony compound added to a resin containing an acrylonitrile-butadiene-styrene copolymer to have excellent flame retardancy, impact strength, scratch resistance, colorability, and surface hardness due to a synergistic effect combination. Background technique [0004] Generally speaking, acrylonitrile-butadiene-styrene resin (hereinafter referred to as "ABS r...
