Abstract
Official abstract text for this publication.
Provided are resin composition and a molded article produced therefrom, the resin composition comprising: a polycarbonate resin; a rubber-modified aromatic vinyl-based copolymer resin; a conductive additive including a carbon fiber and a carbon nanotube; talc; and a foaming agent, wherein the carbon fiber and the carbon nanotube are contained in a weight ratio of 1:0.1 to 1:0.4.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin composition, comprising: a base resin comprising: a polycarbonate resin; a rubber-modified aromatic vinyl-based copolymer resin; a conductive additive comprising a carbon fiber and a carbon nanotube; talc; and optionally a phosphorus-based flame retardant; and a foaming agent, wherein a weight ratio of the carbon fiber and the carbon nanotube is 1:0.2 to 1:0.4. 2. The resin composition of claim 1 , comprising the foaming agent in an amount of 0.5 to 5 parts by weight based on 100 parts by weight of the base resin composition. 3. The resin composition of claim 1 , comprising 1 to 10 wt % of talc based on 100 wt % of the base resin composition. 4. The resin composition of claim 1 , wherein the resin composition comprises the phosphorus-based flame retardant and a flame retardant auxiliary agent. 5. The resin composition of claim 4 , comprising the phosphorus-based flame retardant in an amount of 5 to 20 wt % based on 100 wt % of the base resin composition. 6. The resin composition of claim 4 , wherein the flame retardant auxiliary agent is polytetrafluoroethylene. 7. The resin composition of claim 4 , comprising the flame retardant auxiliary agent in an amount of 0.2 to 2 parts by weight based on 100 parts by weight of the base resin composition. 8. A molded article produced from the resin composition of claim 1 . 9. The molded article of claim 8 , wherein the molded article has a sheet resistance of less than or equal to 10 5 Ohm/sq. 10. The molded article of claim 8 , wherein the molded article has flame retardancy of greater than or equal to V-1 according to UL94 standard.
