NOVELTY - Electromagnetic shielding rubber comprises 30-55 pts. wt. dihydroxy polydimethylsiloxane, 26-45 pts. wt. filling agent, 5-10 pts. wt. nano carbon black, 0.6-1.2 pts. wt. graphene, 0.05-0.15 pts. wt. silane coupling agent, 0.05-3 pts. wt. shielding material 201E, and 0.5-2.5 pts. wt. curing agent. USE - Used as the electromagnetic shielding rubber. ADVANTAGE - The shielding rubber: has low raw material cost and excellent shielding effect. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing electromagnetic shielding rubber comprising kneading dihydroxy polydimethylsiloxane, filling agent, nano carbon black, and graphene uniformly, grinding finely, stirring at high speed with a high-speed disperser for mixing uniformly, then dehydrating at 110-150 degrees C, adding silane coupling agent, shielding material, and curing agent after vacuum cooling, and stirring in vacuum; and (2) electronic device comprising electromagnetic shielding rubber.
