Abstract

The invention discloses a heat-conducting conductive elastomer material and a preparation method thereof. The elastomer material is prepared from the following components in parts by weight: 10 to 50 parts of phenylethylene elastomer, 10 to 50 parts of mineral oil, 10 to 50 parts of polyolefin, 5 to 40 parts of metal fibers, 5 to 20 parts of nanometer copper powder, 1 to 5 part(s) of antioxygen and 5 to 40 parts of expanded graphite. Compared with the prior art, the heat-conducting conductive elastomer material provided by the invention has a better heat-conducting effect, and a thermal coefficient of the material can reach above 4W/m.K; and moreover, the material has the advantages of good electromagnetic shielding effect, heat conduction, electric conduction, softness and low hardness.

Description

technical field [0001] The invention belongs to the field of polymer materials, and relates to a novel heat-conducting and electrically-conducting elastomer material and a preparation method. Background technique [0002] With the development of electronic industrialization, electronic components are developing towards intensive and high performance. More and more manufacturers hope to make electronic products thinner and lighter. This has formed the trend of lightweight, thin and miniaturized products. This trend puts forward higher requirements for the heat dissipation of electronic products. [0003] Improving the thermal conductivity of the material can significantly improve the heat dissipation performance of the product. Existing thermally conductive polymers have been studied in the field of engineering plastics, such as thermally conductive PPS, etc., but relatively few studies have been conducted on the thermally conductive aspects of elastomers. There are paten...
