Abstract:
      A flexible electromagnetic shielding anti mold coating material（electromagnetic shielding coating material）was prepared and its properties were studied.The results showed that the electromagnetic shielding coating material prepared with a viscosity of 15 000 MP·s of methyl vinyl liquid silicone rubber，a dosage of 5 ‰ of 2-bromo-2-nitro-1，3-propanediol，1% of mold inhibitor，69.35% of conductive powder，and 7.38% of mineral oil had the best comprehensive performance.Its electromagnetic shielding efficiency was≥60 dB（10 MHz～10 GHz），shear strength was 0.95 MPa，peel force was 13.46 N·cm-1，and antibacterial performance reached level Ⅰ.It could effectively meet the requirements of low viscosity，good adhesion，excellent shielding performance，and good antibacterial performance of electromagnetic shielding coating materials when used in extreme environments.
