THERMOPLASTIC RESIN COMPOSITION, METHOD FOR PREPARING SAME, AND MOLDED PRODUCT MANUFACTURED THEREFROM
The present invention relates to a thermoplastic resin composition, a method for preparing same, and a molded product manufactured therefrom and, more specifically, to a thermoplastic resin composition, a method for preparing same, and a molded product manufactured therefrom, the thermoplastic resin composition comprising: A-1) 3-22 wt% of a graft copolymer comprising acrylate-based rubber having an average particle diameter of 200-400 nm, an aromatic vinyl compound, and a vinyl cyan compound; A-2) 17-40 wt% of a graft copolymer comprising acrylate-based rubber having an average particle diameter of 50-199 nm, an aromatic vinyl compound, and a vinyl cyan compound; B) 30-57 wt% of a copolymer comprising a (meth)acrylic acid alkyl ester compound, an ?-methyl styrene-based compound, and a vinyl cyan compound; and C) 6-30 wt% of polymethacrylate resin (excluding ?-methyl styrene), and the thermoplastic resin composition having an average surface impact strength of 22 J or greater and a standard deviation of 6.5 or less, which are obtained through measurement of the maximum load energy 10 times with a specimen thickness of 2.0 mm at a rate of 4.4 m/s in accordance with ISO 6603-2. According to the present invention, there is the effect of providing a thermoplastic resin composition, a method for preparing same, and a molded product manufactured therefrom, the thermoplastic resin composition having excellent impact resistance, heat resistance and fluidity, and in particular, an increased average surface impact strength and a reduced standard deviation thereof, thus enabling the injection molding of large-scale products, and being able to realize a deep black color and preventing the occurrence of goniochromism, thus satisfying the evaluation of injection appearance quality and automobile reliability.
