Embodiment 1

[0075] The details of the components used in Examples and Comparative Examples are as follows:

[0076] (A) Polycarbonate resin

[0077] A bisphenol A type polycarbonate having a weight average molecular weight (Mw) of 25,000 g / mol was used.

[0078] (B) Rubber modified aromatic vinyl copolymer resin

[0079] A resin prepared by kneading (B-1) 40 wt% of a styrene-based graft copolymer resin and (B-2) 60 wt% of a styrene-containing copolymer resin was used.

[0080] (B-1) Styrenic graft copolymer resin (ABS graft copolymer resin)

[0081] 50 parts by weight of butadiene rubber latex was placed in the reactor, and 36 parts by weight of styrene, 14 parts by weight of acrylonitrile and 150 parts by weight of deionized water were added into the reactor based on the solid content. Then, relative to the total solid content, 1.0 parts by weight of potassium oleate, 0.4 parts by weight of cumene hydroperoxide, 0.2 parts by weight of mercaptan chain transfer agent, 0.4 parts by weigh...

Embodiment 1 to 3 and comparative example 1 to 9

[0088] Each component was introduced into a twin-screw melt extruder in the amount listed in Table 1 at 240° C. to 280° C., followed by melting and kneading, whereby a wafer-like resin composition was prepared. The prepared wafers were dried at 80° C. for 5 hours or more, and then samples for measuring flame retardancy and mechanical properties were prepared at 240° C. to 280° C. using a screw injector. The prepared samples were evaluated for the following properties, and the results are shown in Table 1.

Abstract

The flame retardant thermoplastic resin composition includes 100 parts by weight of a polycarbonate resin; 5 parts by weight to 30 parts by weight of a rubber modified aromatic vinyl-based copolymer resin; 10 parts by weight to 30 parts by weight of an aromatic phosphoric acid ester compound; and 5 parts by weight to 100 parts by weight of fillers including wollastonite and talc, wherein a weight ratio of wollastonite to talc ranges from 1:0.1 to 0.5. In the flame retardant thermoplastic resin composition, wollastonite and talc are present in a specific ratio, thereby providing excellent properties in terms of stiffness such as flexural modulus and bending characteristics, and flame retardancy.

Description

technical field [0001] The present invention generally relates to flame retardant thermoplastic resin compositions and articles comprising the same. More specifically, the present invention relates to a flame-retardant thermoplastic resin composition containing wollastonite and talc in a specific ratio to improve rigidity (such as flexural modulus, flexural properties, etc.) and flame retardancy, and to an article containing the same. Background technique [0002] Polycarbonate resin is an engineering plastic material that has excellent properties in terms of mechanical strength, heat resistance, transparency, and the like. Polycarbonate resins are used in a variety of fields, including office automation equipment, electrical / electronic components, construction materials, and the like. In particular, polycarbonate resins used for exterior materials of electric / electronic parts such as TVs, monitors, notebook computers, etc. should exhibit high fluidity to obtain a slim and ...
