The volume resistance of the conductive rubber filled with conductive carbon black can usually be kept at several thousand ohms. Since a single acetylene carbon black is used in the existing formula, its tensile strength can only reach 12Mpa, which is far from meeting the actual needs.

technical field [0001] The invention relates to the technical field of rubber products, in particular to a conductive rubber. Background technique [0002] Conductive rubber usually means that the volume resistance is within 9 times of 10 ohm centimeters. Since rubber is an excellent insulator, the volume resistance is greater than about 14 times of 10. Conductive rubber is divided into anti-static grade conductive rubber. The volume resistance is between 10 to the 9th power of 10, or even as low as one or two hundred ohms. It is very difficult to lower it to less than 50 ohm cm. The volume resistance of the conductive rubber filled with conductive carbon black can usually be kept at several thousand ohms. Since a single acetylene carbon black is used in the existing formula, its tensile strength can only reach 12Mpa, which is far from meeting the actual needs. Conductive rubber is used in both military and commercial applications, where its main role is sealing and electro...
