Abstract

The invention provides a thermoplastic resin composition having excellent flame retardancy, colorability and thermal stability. The thermoplastic resin composition comprises (A) about 45 to about 95% by weight of an aromatic copolymer, (B) about 5 to about 55% by weight of a polycarbonate resin, (C) about 1 to about 30 parts by weight of a halogen-containing compound based on about 100 parts by weight of the aromatic copolymer (A) and the polycarbonate resin (B), and (D) about 0 to about 2 parts by weight of an antimony compound based on about 100 parts by weight of the aromatic copolymer (A) and the polycarbonate resin (B). The thermoplastic resin composition can have excellent flame retardancy, colorability and thermal stability.

Description

technical field [0001] The present invention relates to a thermoplastic resin composition that can have excellent flame retardancy, colorability, and thermal stability. Background technique [0002] In general, rubber-modified styrenic copolymer resins have good mechanical strength, processability, excellent impact strength, and good appearance, and thus are widely used in the manufacture of electrical and electronic goods. However, the rubber-modified styrenic copolymer resin has no flame resistance and if it is ignited, the rubber-modified styrenic copolymer resin may cause the spread of fire. [0003] Therefore, many countries such as the United States, Japan, and many European countries have passed laws requiring polymer resins to meet flame retardancy standards to ensure stability in the presence of fire. [0004] Various techniques can impart flame retardancy to polymers. For example, many commonly used and well-known methods of flame retardancy are the addition of f...
