Embodiment 1 and 2 and comparative example 1 to 6

[0112] The components were mixed in a typical mixer according to the compositions shown in Table 1 below. The mixture was extruded using a twin-screw extruder with L / D = 35 and Φ = 45 mm, and the extrudate was made into a pellet shape.

[0113] A 10-ounce injection molding apparatus and the prepared pellets were used to manufacture test specimens for measuring mechanical properties and evaluating flame retardancy at injection temperatures of 280°C to 300°C.

[0114] (Table 1)

[0115] (Unit: parts by weight)

[0116]

[0117] The samples manufactured as above were individually preserved for 48 hours at 23° C. and a relative humidity of 50%, and their mechanical properties were evaluated. The results are given in Table 2 below.

[0118] (1) Flame retardancy: Evaluation was performed using a sample with a thickness of 1.5 mm in accordance with the regulations of UL-94.

[0119] (2) Notched Izod Impact Strength: Measured using 1 / 8" specimens according to ASTM D256 specific...

Abstract

The flame retardant polycarbonate resin composition of the present invention includes (A) a polycarbonate resin, (B) a rubber-modified vinyl-based graft copolymer, (C) a metal salt of sulfonic acid, and (D) an anti-drip agent including a fluorinated terpolymer. The polycarbonate resin composition of the present invention has excellent flame retardancy, heat resistance, and mechanical strength, well-balanced mechanical properties such as impact resistance, heat resistance, and fine workability, and an excellent appearance characteristic. Therefore, it is useful for fabrication of molded products such as electric household appliances, office appliances, electrical and electronic devices, and internal parts thereof.

Description

technical field [0001] The invention relates to a flame-retardant polycarbonate resin composition. More specifically, the present invention relates to a flame-retardant polycarbonate resin composition that does not deteriorate in mechanical and appearance properties. Background technique [0002] Due to its transparency, excellent electrical characteristics, and excellent mechanical properties such as high impact resistance, polycarbonate resins have various applications, such as for office automation devices, communication devices, and electrical and electronic products. [0003] Resin compositions used in office automation devices and electrical and electronic products require strict safety regulations, and in particular, it should comply with flame retardancy regulations. In order to obtain flame retardancy of the resin composition, a flame retardant such as a halogen-containing compound, a phosphorus-containing compound, a metal sulfonate compound, or a silicon-based co...
