NOVELTY - Pantograph carbon skateboard comprises 2-40 pts. wt. carbon black, 20-50 pts. wt. coke, 1-8 pts. wt. carbon fiber, 20-50 pts. wt. graphite, 1-2 pts. wt. internal demolding agent, 1-4 pts. wt. graphene, 1-15 pts. wt. copper fiber. USE - Pantograph carbon skateboard. ADVANTAGE - The pantograph carbon skateboard is used to modify the existing carbon slide to solve the poor impact toughness of the carbon slide, prevents from locomotive accidents and cost-effective, and provides safety of electric locomotive operation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a pantograph carbon skateboard, which involves: (A) putting the carbon strip raw material for the pantograph carbon slide in the kneading pot, and performing kneading treatment to obtain a mixed material; (B) pre-pressing the mixed material to prepare a carbon strip preform for a carbon slide; (C) placing carbon blank for carbon slide in an extruder and subjecting to an extrusion molding process to prepare a carbon strip for the carbon slide; and (D) using carbon strip for a pantograph carbon slide by firing the carbon strip blank for the carbon slide.
