Definitions
- the present invention relates to a thermoplastic resin composition and a molded article using the same.
- thermoplastic resins which are being widely applied to electrical and electronic equipment, automobiles, building materials, and leisure products, are rapidly replacing the existing glass and metal fields. Accordingly, the demand for a thermoplastic resin capable of implementing excellent impact resistance, water resistance, scratch resistance and antibacterial properties is increasing.
- an antifouling (anti-pollution) coating, antibacterial additive, or antistatic additive to fundamentally prevent contamination of unpainted materials used in automobile interior parts and maintain a safe sanitary condition
- Various methods have been tried, such as injecting
- thermoplastic resin composition having excellent scratch resistance and antibacterial properties.
- thermoplastic resin composition excellent in scratch resistance, abrasion resistance, water resistance, chemical resistance and antibacterial properties, and a molded article using the same.
- thermoplastic resin composition (A) 1 to 3 parts by weight of a core-shell copolymer including (B) an acrylic rubbery polymer core and a (meth)acrylate-based shell based on 100 parts by weight of the polyalkyl (meth)acrylate resin ; (C) 2 to 5 parts by weight of a siloxane-polyester copolymer; and (D) zinc oxide (ZnO) 1 to 5 parts by weight, a thermoplastic resin composition is provided.
- the glass transition temperature (Tg) of the (A) polyalkyl (meth)acrylate resin may be 100 to 150 °C.
- the weight average molecular weight of the (A) polyalkyl (meth)acrylate resin may be 50,000 to 200,000 g/mol.
- the (A) polyalkyl (meth)acrylate resin may be a polymethyl methacrylate resin.
- the (B) core-shell copolymer comprising an acrylic rubbery polymer core and a (meth)acrylate-based shell includes: an acrylic rubbery polymer core in which C1 to C20 linear alkyl acrylate monomers and aromatic vinyl monomers are crosslinked; and a shell in which a (meth)acrylate-based compound is graft-copolymerized onto the acrylic rubbery polymer core. It may be a copolymer having a core-shell structure.
- the core-shell copolymer including a shell may be a copolymer having a core-shell structure in which polymethyl methacrylate forms a shell on a butyl acrylate-styrene cross-linked copolymer core.
- the average particle diameter of the acrylic rubber polymer may be 0.5 to 5.0 ⁇ m.
