摘要： Provided are a method for preparing a conductive resin composition, and a method for preparing a conductive resin molded product by using the composition to obtain sufficient electrical conductivity by using a small amount of stainless steel fiber as a conducting material. The preparation method of a conductive resin composition comprises the steps of sizing a plurality of sheets of stainless steel fiber with a thermoplastic polymer and cutting it by a length of 3-8 mm to obtain a stainless steel fiber pellet; injecting a synthetic resin into the main hopper(10) of a screw and injecting 1-9 wt% of the stainless steel fiber pellet to the screw based on the weight of the synthetic resin in the front of a mixing zone or pulverizing zone when the mixing is initiated; and mixing the synthetic resin and the stainless steel fiber pellet in a screw comprising at least one mixing zone(40), at least one pulverizing zone(50), and at least one reverse zone(60). In the reverse zone, the flow is reversed and the content is not flow in any direction and is just rotated.
