| titleOfInvention | Firing pencil lead |
| abstract | In a fine-wire-shaped fired pencil lead, a fired lead is obtained, but if a sufficient breaking strength is obtained, the lead is hard to be worn and the handwriting density is lowered. This problem is improved and a fired pencil lead having a good balance between bending strength and writing line density is provided. A compounding material in which a weight ratio of a thermoplastic resin to a total weight of graphite and a thermoplastic resin is 42 to 50% by weight is kneaded and extruded into a thin wire, and then subjected to heat treatment, and the cross-sectional diameter is A fired pencil lead in which a plurality of ridges having a height of 0.3 to 4.5% with respect to the transverse cross-sectional diameter are formed in the longitudinal direction of the side wall while being 0.05 to 0.25 mm. [Selection figure] None |
