NOVELTY - Electromagnetic shielding composite material comprises 35-52 pts. wt. high imino high methyl etherified melamine resin, 10-20 pts. wt. hydroxyl acrylic resin, 15-23 pts. wt. graphene oxide, 8-14 pts. wt. carbon fiber, 3-9 pts. wt. azodicarbonamide, 0-5 pts. wt. filler and 2-7 pts. wt. adhesive. USE - Used as electromagnetic shielding composite material. ADVANTAGE - The material: has attenuation of the electromagnetic wave, reaches the purpose of electromagnetic shielding, and can reach the maximum electromagnetic shielding efficiency of 35 dB. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing electromagnetic shielding composite material comprising firstly taking high imino high methyl etherified melamine resin, hydroxyl acrylic resin and azodicarbonamide, mixing uniformly to obtain the first mixture, then adding graphene oxide, carbon fibre and filler into the first mixture, fully mixing again to obtain the second mixture, adding adhesive into the second mixture, stirring uniformly, adding the obtained mixture into a mold, and placing the mold on a vulcanizing machine for preheating, then foaming at a certain temperature and pressure, cooling the mold to room temperature and demolding to obtain the product.
