[0201] [Manufacture of resin pellets]

[0202] The components shown in Table 1 were blended in the ratios (mass ratios) given in Tables 3 and 4 below, and after mixing in a drum for 20 minutes, were fed to a twin-screw extruder equipped with a vent. machine (TEX30HSST, from TheJapan SteelWorks, Ltd.), and kneaded at a screw rotation speed of 200rpm, an extrusion speed of 15kg / hour, and a barrel temperature of 280°C. The molten resin was extruded into a strand form and quenched in a water bath and pelletized using a pelletizer to obtain pellets of the polycarbonate resin composition.

[0203] [Evaluation of flame retardancy by UL94 test]

[0204] After drying the pellets obtained by the above production method at 120°C for 4 hours, they were molded by injection molding at a cylinder temperature of 270°C and a mold temperature of 80°C using a model SE100DU injection molding machine from Sumitomo Heavy Industries, Ltd. A test piece for UL testing with a length of 125 mm, a widt...

Abstract

Provided is a polycarbonate resin composition which has high flame retardance and high impact resistance and exhibits excellent thermal stability. A polycarbonate resin composition characterized by containing, per 100 parts by mass of a polycarbonate resin (A), 0.001 to 1 part by mass of an organosulfonic acid metal salt (B) and 0.5 to 5 parts by mass of a core-shell type graft copolymer (C) which comprises a butadiene-based rubber component as the core and which has an Si content of 300ppm or more, and further containing 0.1 to 3 parts by mass of a metal salt (D) of an organophosphoric ester per 100 parts by mass of the core-shell type graft copolymer (C).

Description

technical field [0001] The present invention relates to a polycarbonate resin composition and to a molded product, more particularly to a polycarbonate resin composition having high flame retardancy, high impact resistance, and excellent thermal stability, and to a polycarbonate resin composition obtained by molding this polycarbonate A molded article obtained from an ester resin composition. Background technique [0002] Polycarbonate resins are resins that exhibit excellent heat resistance, excellent mechanical properties, and excellent electrical properties, and are therefore widely used in, for example, automotive materials, electrical and electronic equipment materials, housing materials, and parts production in other industrial fields with material. In particular, the flame-retardant polycarbonate resin composition is advantageously used, for example, in office automation equipment and information processing equipment, such as components of computers, notebook persona...
