High and low temperature resistant electromagnetic shielding adhesive and preparation method thereof

The invention belongs to the technical field of electromagnetic shielding materials, and particularly relates to a high and low temperature resistant electromagnetic shielding adhesive and a preparation method thereof. The high and low temperature resistant electromagnetic shielding adhesive is prepared from an electromagnetic shielding adhesive component A and an electromagnetic shielding adhesive component B in a ratio of 10: 1, wherein the electromagnetic shielding adhesive component A is prepared from silicon rubber, epoxy resin, polyaniline, silver coated copper powder, carbon nanotubes, conductive zinc oxide, gasoline, butyl titanate, KYC913 and organic tin; and the electromagnetic shielding adhesive component B consists of tetraethoxysilane, polyethylene polyamine and gasoline. The electromagnetic shielding adhesive does not contain precious metals such as gold and silver, so that the production cost is greatly reduced, and the process is simple and easy to control; the electromagnetic shielding adhesi
