example 1-13 and comparative example 1-8

[0158] Each ingredient was dry-blended in the amount shown in Table 1 and Table 2, and then the mixture was extruded using a twin-screw extruder (L / D=35, Φ=45 mm) to prepare an extruded mixture as pellets. The prepared pellets were injected at 280° C. using a 10 oz injection machine to prepare test samples for measuring various physical properties.

[0159] In Table 1 and Table 2, the mixing ratio of (A), (B) and (C) is expressed in % by weight of each ingredient, based on 100% by weight of (A) and (B), and ( C) is expressed in parts by weight based on 100 parts by weight of (A)+(B).

Abstract

An electric conductive resin composition comprises about 0.5 to about 5 parts by weight of (C) carbon nanotubes, based on about 100 parts by weight of a base resin comprising about 50 to about 97% by weight of (A) a polycarbonate resin and about 3 to about 50% by weight of (B) a rubber-modified aromatic vinyl resin (B1), a semi-crystalline polymer resin (B2), or a mixture thereof. The electric conductive resin composition has a surface resistance of about 105Ω / □ or less and can have excellent conductivity. Further, the composition can have excellent productivity, tensile strength and / or tensile elongation, and / or generates little dust.

Description

technical field [0001] The present invention relates to a polycarbonate resin composition. More specifically, the present invention relates to a polycarbonate resin composition capable of excellent electrical conductivity. Background technique [0002] Generally, light emitting diodes (hereinafter "LEDs") are manufactured in a chip state as electronic components such as semiconductor packages, and then packaged with various types of packaging materials for safe transportation to users. [0003] The most widely used packaging material is carrier tape, which can be triple layered or single layered. In a pocket formed inside the carrier tape, the carrier tape carries electronic components of the LED chip to prevent external impact during transportation or handling of the electronic components. [0004] Common conductive resins used for carrier tapes may include polycarbonate resins containing polycarbonate resins and carbon black. However, a carrier tape using carbon black m...
