Claims15
A conductive resin composition comprising:
- 10 to 40 wt % of a first copolymer having an average particle size of 1 to 5 μm;
- 30 to 60 wt % of a second copolymer having an average particle size of 0.1 to 1 μm;
- 10 to 20 wt % of a third copolymer prepared by copolymerizing styrene and butadiene in a weight ratio of 60 to 80:20 to 40;
- 1 to 10 wt % of a conductive filler;
- and
- 5 to 10 wt % of a rubber component.
A method of preparing a conductive resin composition, comprising:
- (a) mixing a first copolymer having an average particle size of 1 to 5 μm and a conductive filler to prepare a masterbatch;
- and
- (b) mixing the masterbatch with a second copolymer having an average particle size of 0.1 to 1 μm, a third copolymer prepared by copolymerizing styrene and butadiene in a weight ratio of 60 to 80:20 to 40, and a rubber component.
