摘　　要：采用机械法和湿法两种共混方法制备了PHBA/PPS共混物 ,热压成型制得共混合金 ,用DSC、TG以及TMA对其热行为进行了对比表征 ,并对共混合金的摩擦性能进行了测试。结果表明 :该共混合金的耐热性能较好、热膨胀系数小、尺寸稳定性好、耐摩擦磨损性能优异。其中湿法共混合金比机械法共混合金具有更加优异的耐磨性能。这种高分子合金有望成为新型高性能耐磨自润滑材料。s PHBA/PPS blends were prepared by both mechanical blending and blending in solvent,followed by hot pressing.The molded blends were characterized by differential scanning calorimetry(DSC),thermogravimetric(TG) and thermo mechanical analysis(TMA).The wear resistance of the blend alloys was also determined.The results indicated that the blend alloys had good heat resistance,lower heat expansion coefficient and good dimensional stability.The thermal and abrasive properties of the product blended in solvent were better than those of the product by mechanical blending process,and the product blended in solvent would become a new high performance,wear resistant and self lubricanting alloy.
