| abstract | (57) 【Abstract】 PROBLEM TO BE SOLVED: Even if a core for a sharp pencil having a diameter of 0.9 mm or less, there is a sufficient amount of wear and a concentration, and as a result, it is possible to obtain the gloss of conventional graphite alone which maintains practical strength. To provide a pencil lead with a pure black tone, unlike some handwriting. [Structure] A pencil lead obtained by using at least an organic binder and a combination of graphite and talc as an extender as a main material, kneading, extruding into a thin wire, firing treatment, and impregnation treatment of an oily substance. , Pencil lead with titanium black added in the material. [Effect] Even with a pencil lead that uses graphite and talc as an extender, it is possible to obtain a pencil lead with a blackish handwriting that has a large amount of wear, a high concentration, and practical strength. |
