PROBLEM TO BE SOLVED: To provide a kneading method for a high lubricating material by using a double-screw extruder for carrying out the high concentration filling of highly lubricating material and achieving easily the improvement and stabilization of the quality and productivity of a lubricating resin molten material. SOLUTION: In a kneading method for a highly lubricating material for melt kneading a rubber, other resin raw materials and the highly lubricating material are kneaded by using a double-screw extruder, the resin raw materials are fed from a feed opening 18 of a double-screw extruder 30, and the highly lubricating material is fed from an additive feed opening 34 arranged on the extruder 30 and melt kneaded at the time after the resin raw materials are melt and softened. |
