摘要： A thermoplastic resin composition including 100 parts by weight of a base resin including 50-95% by weight of a polyarylene ether resin (a-1) and 5-50% by weight of a polystyrene resin (a-2); 8.5-16 parts by weight of two or more types of organophosphorus flame retardants (b) having different phosphorus contents; 0.5-3 parts by weight of organoclay (c); 0.5-3.5 parts by weight of pulverized mica (d); 1-4 parts by weight of an alkaline earth metal sulfate (e); and 1-5 parts by weight of a polyfunctional reactant (f), a method of preparing the thermoplastic resin composition, and a molded article including the thermoplastic resin composition. The thermoplastic resin composition has excellent mechanical properties, such as impact strength and tensile strength, heat resistance, electrical insulation, and flame retardancy.
