摘　　要：由微观和唯象分析建立了橡胶粘附摩擦的理论模型。通过对模型的分析和实验验证 ,提出了提高密炼机混炼效果的新途径 :( 1 )密炼机温度控制采用温水冷却 ,使密炼机处于最佳工作状态 ;( 2 )通过合理选择密炼室和转子表面材料以改变材料表面能来增大胶料与它们之间的摩擦力 ;( 3)在上顶栓压力较大的条件下 。]From the viewpoint of microscopic and phenomenological analyses,rubber friction theoretical model was developed.By analyzing and experimentally verifying the model,new ways of improving mixer performance were put forward. (1) Heat water should be used in the mixers temperature control to make the mixer work with optimal parameters. (2) The surface materials of the mixing chamber and rotors should be chosen rationally to change material surface energy and increase friction on them.(3)When the compound was processed under higher pressure of floating weight,shallow groovers or stripes parallel to the axle of the rotor should be made on the mixing chamber internal wall to increase the real contact area and improve mixing effect.
