Description

BACKGROUNDFIELD OF DISCLOSUREThe present disclosure / invention relates to a thermoplastic resin composition and a molded article containing the same. In particular, the resin composition can obtain good dimensional stability and high temperature thermal deformation resistance by incorporating an inorganic filler and an aromatic polyester into a polycarbonate resin and a polycarbonate-polysiloxane copolymer.DESCRIPTION OF THE RELATED ARTOf all thermoplastic resins, acrylonitrile-butadiene-styrene (ABS) resins have excellent mechanical strength, moldability, color generation and plating properties, and are therefore used in a variety of fields including automobiles, home appliances, office automation (OA), and the like. However, ABS resins have insufficient thermal and impact resistance, so that their use is limited. On the other hand, polycarbonate resins are characterized in that moldability and impact strength at low temperatures are poor despite their excellent thermal and impact strength (e.g., impact strength), so that their use is restricted.In order to solve these problems, methods of blending ABS resins and polycarbonate resins are often used to compensate for the disadvantages of the respective materials. In particular, a polycarbonate-ABS (PC-ABS) resin excellent in mechanical strength, moldability, impact resistance and heat resistance can be obtained by blending an ABS resin and a polycarbonate resin. Such PC-ABS resins are used in various fields for interior and exterior parts, including automotive interior parts which require stability in the event of a collision.With recent environmental regulations, electric vehicles have grown in market. In this case, electric vehicles generally have a shorter range than vehicles with an internal combustion engine, so that it is important to achieve the maximum range. In particular, the batteries installed in each electric vehicle are significantly heavy. Therefore, it is desired to reduce the weight of parts used in electric vehicles to increase the range and improve the fuel efficiency.In order to reduce the weight of parts used in electric vehicles, it has been attempted to replace metal with the above-described PC-ABS resin and reduce the thickness of a molded article. However, the reduction in thickness leads to problems such as susceptibility to thermal deformation, and therefore efforts to improve quality should be less of the subject.EXPLANATION OF THE INVENTIONThe present disclosure / invention made to solve the above problems aims to improve good dimensional stability and high temperature thermal deformation resistance by incorporating an inorganic filler and an aromatic polyester into a thermoplastic resin used in automobiles (e.g., automobiles).Moreover, the present disclosure / invention aims to obtain interior and exterior parts for automobiles (e.g., automobiles), ships, and civil engineering, having excellent mechanical properties and heat resistance by producing a molded article using a thermoplastic resin composition having improved dimensional stability and improved thermal deformation resistance.The objects of the present disclosure / invention are not limited to the above objects.

When the amount of the polycarbonate resin is less than 40 wt %, the impact resistance (e.g., impact resistance) and heat resistance (e.g., heat resistance) of a finally commercialized molded article containing the thermoplastic resin composition may be poor. When the amount of the polycarbonate resin exceeds 80 wt %, the amounts of the aromatic polyester resin and the inorganic filler in the thermoplastic resin composition are decreased, and therefore, the moldability and mechanical rigidity may be poor.The polycarbonate resin may be produced by a method of reacting a diphenols-based compound with phosgene, haloformate or carbonic acid diester, but is not limited thereto, and may be produced by various methods used in the art related to the present disclosure / invention.In one embodiment, at least a portion of the polycarbonate resin may be post-consumer recycled polycarbonate (PCR-PC) resin. The PCR PC resin may be a product containing plastic which, after use by the end user, has been disposed of, recovered from the source and then mechanically and chemically recycled.Mechanical recycling may mean crushing the collected resin, washing and melting the resin to make it into a pellet form, and mixing the pellet-shaped resin with raw materials alone containing polycarbonate-containing raw materials in a predetermined ratio for reuse. Chemical recycling may mean a method of extracting only certain polymers from plastic or recovering certain polymers as pure monomolecular substances for repolymerization.The polycarbonate resin recycled by such a method may have a similar or identical chemical composition to a polycarbonate resin made of petrochemical raw materials.The thermoplastic resin composition according to the present disclosure / invention may contain 10 to 30 wt % of the PCR-PC resin. If the amount of the PCR-PC resin is less than 10 wt %, environmental friendliness may be insufficient. When the amount of the PCR-PC resin exceeds 30 wt %, the process cost may increase (e.g., be increased).In one embodiment, the polycarbonate resin may include at least one selected from the group consisting of one(s) bisphenol A polycarbonate resin, one(s) tetramethyl polycarbonate resin, one(s) bisphenol Z polycarbonate resin, one(s) tetrabromo polycarbonate resin, one(s) tetraacryloyl polycarbonate resin, or any combination thereof. In one example, the bisphenol A polycarbonate resin is used to obtain excellent compatibility and impact resistance.In one embodiment, the polycarbonate resin may have a weight average molecular weight (Mw) in a range of 10,000 to 40,000. When the weight average molecular weight of the polycarbonate resin is below 10,000, the impact resistance of the molded article containing the thermoplastic resin composition may be poor. When the weight average molecular weight of the polycarbonate resin exceeds 40,000, the dispersion and elongation of the thermoplastic resin composition may be poor. In addition, the impact resistance of the molded article containing the thermoplastic resin composition may be poor.In one example, the polycarbonate resin has a weight average molecular weight in the range of 15,000 to 35,000. When the weight average molecular weight of the polycarbonate resin falls within the above numerical range, the impact resistance and the heat resistance temperature of the molded article containing the thermoplastic resin composition can be significantly improved.In one embodiment, the polycarbonate resin may have a melt flow index in a range of 10 to 35 grams per ten minutes (g / 10 min), measured according to ISO 1133 standard at a temperature of 300° C. and a load condition of 1.2 kg. Moreover, the PCR-PC resin may have a melt flow index in a range of 10 to 35 g / 10 min, measured according to the standard ISO 1133 at a temperature of 300° C. and a load condition of 1.2 kg.If the melt flow index of the polycarbonate resin or the PCR-PC resin is less than 10 g / 10 min, the flowability of the thermoplastic resin composition may be poor, resulting in deterioration of moldability. When the melt flow index of the polycarbonate resin or the PCR-PC resin exceeds 35 g / 10 min, the mechanical properties of the thermoplastic resin composition and the molded article containing the same may be deteriorated.(B) Polycarbonate-polysiloxane copolymer resinThe thermoplastic resin composition according to the present disclosure / invention may comprise 1 to 20 wt % of the polycarbonate-polysiloxane copolymer resin. When the amount of the polycarbonate-polysiloxane copolymer resin is less than 1% by weight, the demoldability (e.g., releasability) may be poor and the impact strength (e.g., impact strength) of the finally commercialized plastic resin sheet may be poor, especially at low temperatures. When the amount of the polycarbonate-polysiloxane copolymer resin exceeds 20 wt %, lowering of the heat-resistant (e.g., heat-resistant) temperature of the thermoplastic resin may result in deterioration of the thermal deformation resistance.The polycarbonate-polysiloxane copolymer may be formed by copolymerizing a polycarbonate block and a poly(diorganosiloxane) block. A monomer mixture of polycarbonate block monomers and poly(diorganosiloxane) block monomers mixed in a weight ratio in a range of 70:30 to 90:10 may be copolymerized.In this case, the poly(diorganosiloxane) block monomers may be included in the monomer mixture in an amount in a range of 10 to 30 wt %. If the amount of the poly(diorganosiloxane) block monomers is less than 10% by weight, the ductility of the thermoplastic resin may be poor, resulting in deterioration of the surface impact strength of the molded article. When the amount of the poly(diorganosiloxane) block monomers exceeds 30% by weight, the low glass transition temperature of the poly(diorganosiloxane) block may result in a decrease in the heat resistance temperature of the thermoplastic resin composition.In one embodiment, the polycarbonate-polysiloxane copolymer resin may have a melt flow index in a range of 1 to 10 g / 10 min, measured according to the standard ISO 1133 at a temperature of 300° C. under a load condition of 1.2 kg. When the melt flow index of the polycarbonate-polysiloxane copolymer resin is less than 1 g / 10 min, the thermoplastic resin composition may have poor flowability, resulting in deterioration of moldability. When the melt flow index of the polycarbonate-polysiloxane copolymer resin exceeds 10 g / 10 min, the mechanical properties of the thermoplastic resin composition and the molded article containing the same may be deteriorated.(C) Aromatic polyester resinThe thermoplastic resin composition according to the present disclosure may include 5 to 30 wt % of the aromatic polyester resin. When the amount of the aromatic polyester resin is less than 5 wt %, moldability and chemical resistance may be poor.In one embodiment, the aromatic polyester resin may have an intrinsic viscosity in a range of 0.6 to 1.3 deciliters per gram (dL / g). When the intrinsic viscosity of the aromatic polyester resin does not fall within the above numerical range, impact resistance, tensile strength, heat resistance, light resistance and chemical resistance of the final molded article may be poor.The aromatic polyester resin may typically be obtained by polycondensation of terephthalic acid (TPA), isophthalic acid (IPA), 1,2-naphthalenedicarboxylic acid, 1,4-naphthalenedicarboxylic acid, 1,5-naphthalenedicarboxylic acid, 1,6-naphthalenedicarboxylic acid, 1,7-naphthalenedicarboxylic acid, 1,8-naphthalenedicarboxylic acid, 2,3-naphthalenedicarboxylic acid, 2,6-naphthalenedicarboxylic acid, 2,7-naphthalenedicarboxylic acid, dimethyl terephthalate (DMT), an aromatic dicarboxylate in which an acid is substituted by a dimethyl group, dimethyl isophthalate, alkyl ester or dimethyl 1,2-naphthalate of naphthalenedicarboxylic acid, dimethyl 1,5-naphthalate, dimethyl 1,7-naphthalate, dimethyl 1,8-naphthalate, dimethyl 2,3-naphthalate, dimethyl 2,6-naphthalate, dimethyl 2,7-naphthalate, or any mixture thereof. The aromatic polyester resin can also be obtained by polycondensation of ethylene glycol having 2 to 12 carbon atoms, 1,2-propylene glycol, 1,3-propylene glycol, 2,2-dimethyl-1,3-propanediol, 2,2-dimethyl-1,3-propylene glycol, 1,3-butanediol, 1,4-butanediol, 1,5-pentanediol, 1,6-hexanediol, 1,3-cyclohexanedimethanol, 1,4-cyclohexanedimethanol, or any mixture thereof, which can be easily implemented by one of ordinary skill in the art to which the present disclosure / invention pertains.The aromatic polyester resin may be a component into which inorganic particles are mixed by an existing method. The inorganic particles may be, but are not limited to, titanium dioxide (TiO 2), silicon dioxide (SiO 2) or aluminum hydroxide (Al(OH) 3).In one embodiment, the aromatic polyester resin may include at least one selected from the group consisting of polybutylene terephthalate (PBT), polyethylene terephthalate (PET), polyethylene terephthalate glycol (PETG), or any combination(s) thereof.(D) Graft copolymer resinThe thermoplastic resin composition according to the present disclosure / invention may include 1 to 20 wt % of the graft copolymer resin in which the rubbery (e.g., rubbery) polymer, the aromatic vinyl monomer, and the vinyl cyanide monomer are polymerized by graft polymerization. In this case, the rubbery polymer of the graft copolymer resin may comprise a diene-based rubbery polymer.In one embodiment, the diene-based rubbery polymer may comprise at least one polymer selected from the group comprising or consisting of polybutadiene, one(s) butadiene aromatic vinyl compound copolymer, one(s) butadiene vinyl cyanide compound copolymer, polyisoprene, or any combination(s) thereof. The butadiene-aromatic vinyl compound copolymer may include a butadiene-styrene copolymer and a butadiene-vinyltoluene copolymer. The butadiene-vinyl cyanide compound copolymer may include a butadiene-acrylonitrile copolymer and a butadiene-methacrylonitrile copolymer.The graft copolymer resin includes a first graft copolymer resin and a second graft copolymer resin, which are described below, respectively.(D-1) First Graft Copolymer ResinThe thermoplastic resin composition may comprise 1 to 10 wt% of the first graft copolymer resin. When the amount of the first graft copolymer resin is less than 1% by weight, impact resistance properties may be poor. On the contrary, when the amount of the first graft copolymer resin exceeds 10 wt %, the glass transition temperature of the thermoplastic resin composition may be lowered, resulting in deterioration of the heat resistance.In one embodiment, the first graft copolymer resin may be polymerized by graft polymerizing 55 to 65 wt % of the diene-based rubbery polymer and 35 to 45 wt % of a monomer mixture of the aromatic vinyl monomer and the vinyl cyanide monomer.The first graft copolymer resin may be polymerized using a known polymerization method such as emulsion polymerization, suspension polymerization, solution polymerization, bulk polymerization, or a combination of two or more thereof. During the graft polymerization, the monomer mixture may be supplied together with a known emulsifier, polymerization initiator, catalyst and the like to the diene-based rubbery polymer at once (e.g., at one stroke), or may be supplied continuously over a certain period of time, as required. The graft copolymer resin originally obtained by graft polymerization can be obtained in a latex form or in a powdery solid form by treating the resin with acid or salt and then coagulating and drying.The first graft copolymer resin may be prepared by an emulsion polymerization method that enables (e.g., facilitates) controlling the particle diameter, but is not limited thereto. The first graft copolymer resin may be polymerized by graft polymerizing the monomer mixture of the aromatic vinyl monomer and the vinyl cyanide monomer mixed in a weight ratio in a range of 60:40 to 80:20 into the diene-based rubbery polymer. In addition, the monomer mixture may comprise 0 to 20 wt % of a monovinyl monomer based on the total weight of the monomer mixture.In one embodiment, the vinyl cyanide monomer may be included in the monomer mixture in an amount of 20 to 40 wt %, based on the total weight of the monomer mixture. When the content of the vinyl cyanide monomer is less than 20 wt %, the kneadability and impact strength of the finished molded article may be significantly poor. When the content of the vinyl cyanide monomer exceeds 40 wt %, the surface properties may be poor due to yellowing occurring when the thermoplastic resin composition is molded at high temperatures. Moreover, the kneadability with other resins may be poor.The monovinyl monomer may include at least one selected from the group consisting of, but is not limited to, maleimide, N-methylmaleimide, N-ethylmaleimide, N-propylmaleimide, N-phenylmaleimide, methyl methacrylate, methyl acrylate, butyl acrylate, acrylic acid, maleic anhydride, or any combination(s) thereof.The first graft copolymer resin may have a graft ratio in the range of 30% to 40%, an average particle diameter in the range of 0.2 to 0.5 micrometer (μm), and a weight average molecular weight in the range of 105,000 to 120,000 grams per mole (g / mol). When the graft ratio of the first graft copolymer resin does not fall within the above numerical range, the dispersion of the thermoplastic resin composition may be reduced, resulting in deterioration of moldability and heat resistance properties.The grafting ratio can be derived from Equation 1 below.In the above equation 1, G is the graft ratio (%), M is g the weight (g) of the monomer polymerized into the rubbery polymer by graft polymerization, and W is c the weight (g) of the rubbery polymer.(D-2) Second graft copolymer resinThe thermoplastic resin composition may comprise 1 to 10% by weight of the second graft copolymer resin. When the amount of the second graft copolymer resin is less than 1% by weight, the quality of appearance including gloss and color rendering may be poor. When the amount of the second graft copolymer resin exceeds 10 wt %, compatibility with other resins may be poor due to an increase in viscosity, resulting in deterioration of mechanical properties.In one embodiment, the second graft copolymer resin may be polymerized by graft polymerizing 45 to 55 wt % of the diene-based rubbery polymer and 45 to 55 wt % of a monomer mixture of the aromatic vinyl monomer and the vinyl cyanide monomer.The second graft copolymer resin may be polymerized using a known polymerization method such as emulsion polymerization, suspension polymerization, solution polymerization, bulk polymerization, or a combination of two or more thereof. During the graft polymerization, the monomer mixture may be supplied to the diene-based rubbery polymer at once together with a known emulsifier, polymerization initiator, catalyst and the like, or may be supplied continuously over a certain period of time as needed. The graft copolymer resin originally obtained by graft polymerization can be obtained in a latex form or in a powdery solid form by treating the resin with acid or salt and then coagulating and drying.The second graft copolymer resin can be produced by an emulsion polymerization method that facilitates controlling the particle diameter, but is not limited thereto.The second graft copolymer resin may be polymerized by graft polymerizing the monomer mixture of the aromatic vinyl monomer and the vinyl cyanide monomer mixed into the diene-based rubbery polymer in a weight ratio in a range of 60:40 to 80:20. In addition, the monomer mixture may further comprise 0 to 20 wt % of a monovinyl monomer based on the total weight of the monomer mixture.In one embodiment, the second graft copolymer resin may have a graft ratio in a range of 40% to 50%, an average particle diameter in a range of 0.05 to 0.15 μm, and a weight average molecular weight in a range of 90,000 to 105,000 g / mol. When the graft ratio of the second graft copolymer resin does not fall within the above numerical range, the dispersion of the thermoplastic resin composition may be reduced, resulting in deterioration of moldability and heat resistance properties. On the other hand, the grafting ratio can be derived from the above equation 1.(D-3) InitiatorIn one embodiment, the first graft copolymer and the second graft copolymer may further each comprise 0.1 to 4.0 parts by weight of an initiator based on 100 parts by weight of the diene-based rubbery polymer and the monomer mixture.In one embodiment, the initiator may comprise at least one selected from the group comprising or consisting of succinic peroxide, benzoyl peroxide, t-butylperoxy laurate, 2,5-dimethyl-2,5-di(benzoylperoxy)hexane, t-butylperoxy acetate, di-t-butylperoxy phthalate, t-butylperoxy maleic acid, cyclohexanone peroxide, t-butyl hydroperoxide, t-butylperoxy-2-ethylhexanoate, p-chlorobenzoyl peroxide, t-butylperoxy isobutyrate, t-butylperoxy isopropyl carbonate, t-butylperoxy benzoate, dicumyl peroxide, 2,5-dimethyl-2,5-di(t-butylperoxy)hexane, t-butylcumyl peroxide, di-t-butyl peroxide, 2,5-dimethyl-2,5-di(t-butylperoxy)hexane-3, alpha'-bis-t-butylperoxy-1,4-diisopropylbenzene or any combination(s) thereof.In addition, the initiator may include a first initiator containing one peroxide group and a second initiator containing two or more peroxide groups, and the initiator may include the first initiator and the second initiator in a weight ratio in a range of 40:60 to 60:40.(E) Inorganic fillerThe thermoplastic resin composition according to the present disclosure / invention may comprise 5 to 30 wt % of the inorganic filler. When the amount of the inorganic filler is less than 5 wt %, the dimensional stability of the finally commercialized plastic molded body may be low, the heat resistance temperature may be lowered, and the mechanical rigidity may be poor. When the amount of the inorganic filler exceeds 30% by weight, poor impact resistance (e.g., impact resistance) and low flowability may result in deterioration of the quality of appearance.In one embodiment, the inorganic filler may comprise at least one selected from the group comprising or consisting of one(s) acicular / n inorganic / n material, one(s) platelet-like / n (e.g. platelet-shaped / s) inorganic / n material, burnt lime, sea foam or any combination(s) thereof. The inorganic filler may be a mixture of the needle-like inorganic material and the plate-like inorganic material. The inorganic filler may be a mixture of the needle-shaped inorganic material and the plate-shaped inorganic material in a weight ratio in a range of 30:70 to 70:30.In one embodiment, the acicular inorganic material may include at least one selected from the group consisting of or including one(s) whisker, wollastonite, a glass fiber(s), a basalt fiber(s), or any combination(s) thereof.The whisker may be, for example, a potassium titanate whisker, a magnesium sulfate whisker, a calcium carbonate whisker or an aluminum borate whisker. In addition, the wollastonite may have been subjected to a hydrophobic surface treatment. Moreover, the glass fiber may be a glass fiber reinforcing agent in which glass fibers coated with a sizing agent such as epoxy, urethane, or silane are joined to form a fiber, but is not limited thereto. In this case, the sizing agent may be contained in an amount of, but is not limited to, 0.05 to 0.1 part by weight based on 100 parts by weight of the glass filament.In addition, the needle-like inorganic material has a needle-shaped (fibrous) shape and may have an average diameter (D) in a range of 0.1 to 20 μm, which is in a range of 1.0 to 15 μm in an example, and may have an average length (L) in a range of 1 to 3,000 μm, which is in a range of 100 to 3,000 μm in an example. Moreover, the aspect ratio (L / D) between the average length and the average diameter may be in a range of 10 to 200, in one example in the range of 20 to 100.In one embodiment, the plate-like inorganic material may include at least one selected from the group consisting of or including talc, mica, kaolin clay, or any combination(s) thereof.The plate-like inorganic material has a thin film shape in which the length of the Z axis (thickness) is small as compared with the cross-sectional area expressed by the length of the X axis and the Y axis. The thin film may have an average thickness in a range of 30 to 700 nanometers (nm), which in one example is in a range of 30 to 300 nm, and may have an average particle size in a range of 0.5 to 20 μm, which in one example is in the range of 1.0 to 10.0 μm. Moreover, an aspect ratio (diameter / thickness) of the average diameter (the average value of the X-axis length and the Y-axis length) to the average thickness (Z-axis length) is in a range of 4 to 30, in an example, in a range of 10 to 30.The average particle size of the plate-like inorganic material refers to the median (e.g., mean) of the particle size distribution measured by X-ray. In particular, the particle size distribution of the plate-like inorganic material can be obtained (e.g. determined) by passing the settling particles through X-rays. Subsequently, the average particle size may be obtained by calculating the median value.(F) Organophosphate ester compoundThe thermoplastic resin composition according to the present disclosure / invention may comprise 0.01 to 1 % by weight of the organophosphate ester compound. When the amount of the organophosphate compound does not fall within the above numerical range, it may be difficult to suppress the thermal decomposition reaction of the polycarbonate resin generated in the manufacturing process of the molded article and the like. Accordingly, metal ions contained in the inorganic filler for enhancing the dimensional stability of the thermoplastic resin composition promote the thermal decomposition of the polycarbonate resin, resulting in deterioration of the impact strength, dimensional stability and appearance quality.In one embodiment, the organophosphate ester compound may include at least one selected from the group consisting of or including a / m monomeric phosphoric ester, a / m monomeric phosphonic ester, a / m oligomeric phosphoric ester, a / m oligomeric phosphonic ester, a(s) phosphonate amine, a(s) phosphazene, or any(s) combination thereof, but is not limited thereto.(G) Vinyl-based copolymer resinThe thermoplastic resin composition according to the present disclosure / invention may comprise 1 to 5 wt % of the vinyl-based copolymer resin. When the amount of the vinyl-based copolymer resin is less than 1% by weight, the compatibility between the polycarbonate resin and the graft copolymer resin may be poor, resulting in deterioration of mechanical properties including impact properties. When the amount of the vinyl-based copolymer resin exceeds 5 wt %, an increase in viscosity of the thermoplastic resin may result in deterioration of moldability.In one embodiment, the vinyl-based copolymer resin may comprise a copolymer of an aromatic vinyl monomer and a vinyl cyan monomer.Moreover, the vinyl-based copolymer resin may be polymerized into the copolymer of the aromatic vinyl monomer and the vinyl cyan monomer by graft polymerization of one selected from the group consisting of one(s) anhydride monomer, one(s) acrylate monomer, or any(s) combination thereof, but is not limited thereto.In this case, the vinyl-based copolymer resin may be polymerized by graft polymerization of 99.0 to 99.9 mol % of the copolymer of the aromatic vinyl monomer and the vinyl cyan monomer and 0.1 to 1.0 mol % of the one selected from the group consisting of the anhydride monomer / monomers, the acrylate monomer / monomers, or a combination(s) thereof.The anhydride monomer may include at least one selected from the group including or consisting of maleic anhydride, 2-methyl-maleic anhydride, 2,3-dimethyl-maleic anhydride, 2-ethyl-maleic anhydride, 2,3-diethyl-maleic anhydride, 2-trifluoromethyl-maleic anhydride, 2,3-bis(trifluoromethyl)- maleic anhydride, 2-methyl-3-trifluoromethyl-maleic anhydride, citraconic anhydride, aconitic anhydride, itaconic anhydride, or any combination(s) thereof, but is not limited thereto.The acrylate monomer may include at least one selected from the group consisting of, but is not limited to, glycidyl methacrylate, methyl methacrylate, ethyl methacrylate, butyl methacrylate, 2-hydroxyethyl methacrylate, or any combination(s) thereof.(H) AdditivesThe thermoplastic resin composition may further contain additives as needed.The additives used to additionally impart various functions to the thermoplastic resin composition may include at least one selected from the group consisting of a / m commonly used stabilizer, a(s) lubricant, a(s) metal soap, a / m ultraviolet absorber, a / m plasticizer, a(s) colorant (pigment and dye), a(s) glass fiber, a / m filler (silica, wood powder, and the like), a(s) flame retardant, a(s) anti-dripping agent, a(s) antibacterial agent, an(s) antifungal agent, or any(s) combination thereof, but are not limited thereto.In particular, the flame retardant can impart flame retardancy to thermoplastic resin compositions whose heat resistance (e.g., heat resistance) and combustion resistance are poor, and can be classified into halogen-based flame retardants, inorganic flame retardants, phosphorus-based flame retardants, and melanin-based flame retardants depending on components.The halogen-based flame retardants may be classified into bromine-based flame retardants and chlorine-based flame retardants. The bromine-containing flame retardants may have excellent flame retardant effect even in small amounts, but plastics are not recyclable, and toxic environmental pollutants such as dioxins may be released upon combustion.The inorganic flame retardant may include, for example, aluminum hydroxide, antimony oxide, magnesium hydroxide, zinc stannate, molybdate, guanidine, zirconium and the like. Such aluminum hydroxide is nontoxic, low in smoke, excellent in electrical insulation and affordable, but its decomposition temperature is in the range of 180°C to 220°C. For this reason, aluminum hydroxide is suitable only for plastics having low processing temperatures. In addition, mechanical properties and processability of plastic materials may be deteriorated because large amounts are needed to secure flame retardancy.The phosphorus-based flame retardant may include, for example, red phosphorus, ammonium phosphate, ammonium polyphosphate, haloalkyl phosphate, and the like. The phosphorus-based flame retardant exhibits excellent flame retardant effects in solid-state reactions and can be particularly effective for plastics containing a large amount of oxygen.The melanin-based flame retardant may include, for example, melanin phosphate, melanin cyanurate, and the like. The melanin-based flame retardant does not develop toxic gases and generates less smoke during combustion, thereby reducing the risk of pollution.As described above, the thermoplastic resin composition according to the present disclosure / invention has improved coating properties such as conductivity, coating adhesion, and appearance. Accordingly, a separate electroless plating process during plating may be omitted, which improves the environmental friendliness and efficiency of the plating process. At the same time, the thermoplastic resin composition has excellent impact resistance and is therefore available as a suitable material for interior and exterior materials of automobiles.Molded Plastic BodyAnother aspect of the present disclosure / invention provides a molded article containing the composition according to the various embodiments mentioned above. In other words, the molded article can be produced by molding the thermoplastic resin composition.The molded article can be used in various fields, for example, automobiles (e.g., automobiles), ships, and interior and exterior materials in construction, depending on the purpose.In one embodiment, the molded article may have an Izod impact strength (according to ISO 180) in a range of 5 to 20 joules per square meter (J / m 2), a tensile strength (according to ISO 527) in a range of 50 to 70 megapascals (Mpa), a heat resistance temperature (at 1.8 MPa, according to ISO 75) in a range of 110° C. to 120° C., a flexural strength (according to ISO 178) in a range of 75 to 95 MPa, and a flexural modulus (according to ISO 178) in a range of 2,500 to 3,500 MPa.Hereinafter, the present disclosure / invention will be described in detail with reference to the following Examples and Comparative Examples.
