Description

technical field [0001] The invention relates to a polymer composition, in particular to a polymer heat-conducting material. Background technique [0002] At present, metal materials are traditionally used as thermal conductive materials, and polymers cannot replace metals due to their low electrical and thermal conductivity. [0003] Polymers can conduct electricity or heat, so their application fields are greatly expanded, and they can be widely used in gears, bearings, telephones, instruments, meters, automation equipment, etc. Contents of the invention [0004] The present invention overcomes the above-mentioned defects, and aims to provide a polymer heat-conducting material. After a lot of creative work, the inventor has completed the present invention. [0005] Specifically, the present invention provides a polymer thermally conductive material, which includes polymethyl methacrylate, conductive iron powder, polybutadiene-styrene-butadiene resin (SBS resin) and Anti...
