▎ 摘　　要

NOVELTY - Preparing high-conductivity master batch particle comprises 70-90 pts. wt. polyamide particles, 20-30 pts. wt. polytetrafluoroethylene particles, 10-15 pts. wt. paraldehyde, 8-10 pts. wt. oxidized graphene powder, 10-13 pts. wt. polyvinyl alcohol, 15-20 pts. wt. activated carbon, 8-10 pts. wt. calcium hydroxide, 5-10 pts. wt. antioxidant, 15-25 pts. wt. antistatic agent and 10-15 pts. wt. nylon fiber, is claimed. USE - The method is useful for preparing high-conductivity master batch particle (claimed). ADVANTAGE - The particle absorbs and conduct the generated electrostatic voltage, reduces the static voltage to the external distribution, reduce damage to circuit board resistors and capacitor, prolongs the service life and is economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing high-conductivity master batch particle comprising (a) taking the polyamide particles, polytetrafluoroethylene particles, paraldehyde, graphene oxide powder, polyvinyl alcohol, activated carbon and calcium hydroxide, adding absolute ethanol, stirring, carrying out ultrasonic oscillation to obtain paste master batch, (b) under the room temperature, taking lignin, calcium sulfate and water, blending in a certain rotating speed wet ball milling on a ball mill to obtain slurry of lignin calcium sulfate dispersed, obtained slurry to dehydrate to obtain lignin-containing water-dispersing calcium sulfate filler, and (c) adding lignin moisture-containing master particle in step (a) raw in slowly adding corresponding preservative and carbon fiber, adding obtained dispersing calcium sulfate, suction filler, simultaneously heating to 70-80 degrees C, refluxing for 1-1.5 hours, filtering, using anhydrous ethanol for washing, surface sprinkling with antioxidant and uniformly mixing.
