Abstract

The invention discloses a conductive resin coating. The conductive resin coating consists of the following components in parts by weight: 60-80 parts of acrylic resin, 20-35 parts of epoxy resin, 10-15 parts of expanded graphite, 2-3 parts of an ethylene diamine tetraacetic acid (EDTA) disodium salt water solution with mass concentration being 48%, 1-3 parts of a silane coupling agent, 15-25 parts of copper powder, 2-5 parts of a silver nitrate solution with mass concentration being 30%, 15-25 parts of carbon black and 22-36 parts of an ethanol solution with mass concentration being 20%. The conductive resin coating, in comparison with the prior art, overcomes the shortcoming of a metal conductive coating which is relatively poor in metal oxidation resistance, and can guarantee relatively good oxidation resistance through a multi-layer structure of an organic acid ester layer on the surface of the copper powder; and the conductive resin coating can meet demands of modern electronics and electrical appliances and has a wide market prospect.
