Embodiment 1～4 and comparative example 1～7

[0093]A pellet-shaped resin compound was prepared by blending the above-mentioned materials (A) to (D) in the amounts shown in Table 1, and then extruding the resulting pellets through a commonly used twin-screw extruder at a temperature of 220 to 260°C. blended materials.

[0094] The pellets of each resin compound were dried at 80°C for 3 hours, and then injection molded using an 8Oz injection molding machine at an injection temperature of 250°C and a mold temperature of 60°C, thereby providing a test for impact resistance, resistance A sample of flammability and pencil hardness.

[0095] For the samples of the present invention and comparative examples prepared as shown in Table 1 below, flame retardancy was evaluated according to the flame retardancy rule in UL94V, and Izod impact strength was evaluated according to ASTM D-256. Pencil hardness was evaluated according to JIS K 5401 using a 10 cm x 10 cm test piece that had been kept at a temperature of 23° C. and a relativ...

Abstract

Disclosed herein is a flame retardant thermoplastic resin composition that has superior scratch resistance and mechanical properties, satisfying requirements for the appearance of housing materials resulting from a recent increase in volume of electrical and electronic products, and that contains a phosphorus-based flame-retarding agent, satisfying requirements for fire safety and prevention of environmental problems. The resin composition with scratch resistance comprises a base resin comprising (A) 30-90 parts by weight of a polycarbonate resin, (B) 10-50 parts by weight of a polymethylmethacrylate resin and (C) 5-50 parts by weight of a polyethylene terephthalate-based resin, and (D) 5-30 parts by weight of a phosphorus-based flame-retarding agent based on 100 parts by weight of the base resin. The composition may further comprise 1-30 parts by weight of an impact modifier based on 100 parts by weight of the base resin.

Description

technical field [0001] The present invention relates to a flame-retardant thermoplastic resin composition having scratch resistance, more particularly, to a composition comprising polycarbonate resin, polymethyl methacrylate resin, polyethylene terephthalate-based resin, phosphorus-based A thermoplastic resin composition that is a flame retardant and impact modifier with outstanding scratch resistance, non-halogen flame retardancy, and processability. Background technique [0002] Polycarbonate (PC) resin is a polymer resin having excellent mechanical strength, transparency, thermal stability, self-extinguishing property, dimensional stability, etc. Polycarbonate resin has excellent properties for electrical and electronic products, vehicle parts, etc. multiple uses. [0003] Since polycarbonate resin has a polymer structure that can promote flame retardancy, polycarbonate resin can be used as a typical flame retardant and easily obtain flame retardancy. [0004] In partic...
