NOVELTY - An electromagnetic shielding honeycomb core material preparing method involves adding 0.5-5 pts. wt. graphene, 1000-2200 pts. wt. deionized water, 50-600 pts. wt. ferrite, 30-200 pts. wt. ferrous cation, 10-100 pts. wt. ammonia water to deionized water and dispersing by using an ultrasonic disperser, adding 10-100 pts. wt. ammonia water and continuing to stir in a water bath for 10-60 minutes, separating the graphene/ferrite particles from the deionized water by using a magnet and preparing the graphene/ferrite slurry having a water content of 10-45%, spreading the fabric carrier on the bottom of the glass container, depositing the graphene/ferrite particles on the container, removing excess moisture and drying to obtain an electromagnetic shielding fabric depositing graphene/ferrite particles, placing a film on both sides of the electromagnetic shielding fabric of the graphene/ferrite particles and pressing the prepreg into a hard sheet to obtain the finished product. USE - Method for preparing electromagnetic shielding honeycomb core material. ADVANTAGE - The method enables preparing electromagnetic shielding honeycomb core material is cost effective manner. DETAILED DESCRIPTION - An electromagnetic shielding honeycomb core material preparing method involves adding 0.5-5 pts. wt. graphene, 1000-2200 pts. wt. deionized water, 50-600 pts. wt. ferrite, 30-200 pts. wt. ferrous cation, 10-100 pts. wt. ammonia water to deionized water and dispersing by using an ultrasonic disperser at a temperature of 30-80 degrees C for 0.5-5 hours, adding 10-100 pts. wt. ammonia water and continuing to stir in a water bath for 10-60 minutes, washing of graphene/ferrite particles with deionized water until the graphene/ferrite suspension is neutral, separating the graphene/ferrite particles from the deionized water by using a magnet and preparing the graphene/ferrite slurry having a water content of 10-45%, spreading the fabric carrier on the bottom of the glass container, pouring the graphene/ferrite slurry with a water content of 10-45% into the container, placing the strong magnet under the container, depositing the graphene/ferrite particles on the container, removing excess moisture and drying to obtain an electromagnetic shielding fabric depositing graphene/ferrite particles, placing a film on both sides of the electromagnetic shielding fabric of the graphene/ferrite particles and pressing the prepreg into a hard sheet, where the graphene/ferrite hard sheet is bonded between two honeycombs by using a film to obtain the finished product.
