▎ 摘　　要

NOVELTY - A shielding coating comprises 1-10 pts. wt. graphene, 0-9 pts. wt. conductive carbon material, 0.5-2 pts. wt. dispersant (I), 0.5-2 pts. wt. dispersant (II), 0.5-2 pts. wt. defoamer, 1-87.5 pts. wt. interface agent, 10-20 pts. wt. binder, and remaining deionized water. The dispersant (I) and the dispersant (II) are one or more of sodium dodecyl sulfonate, sodium sulfate, sodium carboxylate. USE - Shielding coating. ADVANTAGE - The shielding coating is environmentally-friendly and has better dispersion effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a shielding coating preparation device, which comprises a frame and a grinding and mixing tank. The grinding and mixing tank is provided with a grinding disc (I), a grinding disc (II), and a stirring filter plate. The grinding disc (I) is fixedly connected to the upper part of the grinding and mixing tank. The grinding disc (I) and the grinding disc (II) are arranged up and down. A feeding hopper is arranged in the middle of the grinding disc (I). A feeding pipe is arranged in the middle of the feeding hopper. The bottom of the feeding pipe is open, and the sides are provided with a number of holes. The bottom of the grinding and mixing tank is provided with a discharge port. The side of the grinding and mixing tank is provided with a circulating discharge port, the circulating discharge port is connected with a circulating pump, and the circulating pump is connected with one end of a circulating pipe. The other end of the circulation pipe is connected with the upper part of the feed pipe, and the stirring filter plate is arranged under the grinding disc (II). The feed pipe, the second grinding plate, and the stirring filter plate are all connected with a motor, and the motor is arranged at the bottom of the frame.
