Description

technical field [0001] The invention belongs to the field of conductive materials, and in particular relates to a conductive composite fluoroether rubber and a preparation method thereof. Background technique [0002] Rubber material is one of the irreplaceable and indispensable key materials in the fields of national economy and science and technology, and it is widely used in various fields. With the continuous progress and development of science and technology and chemical industry, various requirements are put forward for the performance of rubber materials. [0003] Rubber itself is a good electrical insulator. In order to make the rubber material better applied in the field of electronic equipment, some filler materials are often added to the rubber material to endow the rubber material with new properties, such as electrical conductivity, magnetic shielding and antistatic properties. Although there are many types of conductive rubber materials in the prior art, most...
