Problems solved by technology

However, most of the conductive materials on the market use acetylene carbon black as the conductive medium. The polymer base materials are mainly natural rubber, EPDM rubber, etc. The conductive rubber made of these raw materials has low conductivity and is easy to age. The performance and shielding efficiency are poor, the preparation process is complicated, the production cost is high, and it cannot meet the actual application requirements

Description

technical field [0001] The invention relates to the field of conductive composite materials, in particular to a preparation process of a novel composite high-performance conductive rubber. Background technique [0002] At present, conductive rubber products have developed well as functional rubber products and are widely used in various industries, such as electromagnetic wave shielding sealing materials, switches, sensors, etc. However, most of the conductive materials on the market use acetylene carbon black as the conductive medium. The polymer base materials are mainly natural rubber, EPDM rubber, etc. The conductive rubber made of these raw materials has low conductivity and is easy to age. The performance and shielding efficiency are poor, the preparation process is complicated, and the production cost is high, which cannot meet the actual application requirements. Contents of the invention [0003] The purpose of the present invention is to overcome the above-menti...
