Abstract

A cable filling strip with anti-electromagnetic interference function and excellent thermal conductivity, the cable filling strip includes the following components in terms of weight components: thermoplastic elastomer, petroleum resin, graphite powder, filter material, flame retardant, auxiliary agent. The cable filling strip with anti-electromagnetic interference function and excellent thermal conductivity described in the present invention can absorb most of the electromagnetic waves projected on its surface by using electromagnetic wave absorbing materials, and convert electromagnetic energy into Heat energy or other forms of energy are consumed, and the reflection, scattering and transmission are very small. While meeting the requirements of traditional cable filler strips for flame retardancy, thermal conductivity and physical and mechanical properties, it can have excellent anti-electromagnetic interference performance. , to avoid the problem of signal crosstalk between the wires caused by the large partial capacitance and mutual inductance between the core wires.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a cable filling strip with anti-electromagnetic interference function and excellent thermal conductivity and a preparation method thereof. Background technique [0002] In electronic equipment and systems, various cables are an indispensable link for signal transmission, and at the same time, cables are the main factor causing various electromagnetic compatibility (EMC) problems. The parallel transmission distance of the wires in the cable is relatively long, so there is a large partial capacitance and mutual inductance between the core wires, which will cause signal crosstalk between the wires and cause unnecessary electromagnetic pollution to the surrounding environment . In the production process of the cable, in order to ensure the roundness of the cable and avoid the mutual friction between the core wires, it is usually necessary to add a cable filler strip between ...
