▎ 摘 要
NOVELTY - An electric brush comprises 35-80 mass% copper powder, 10-60 mass% graphite powder, 0.5-30 mass% graphene powder and 0-20 mass% thermosetting resin. USE - Electric brush. ADVANTAGE - The electric brush is prepared with improved electrical and mechanical properties and service life, low resistivity, small electric spark, low coefficient of friction and high wear resistance at low cost and large scale in a simple, stabilized, continuous and automated manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing the electric brush.
