摘要： 采用磨盘形力化学反应器,在室温下制备了PA6/PP超细混合粉体,与SBS共混制得PA6/PP/SBS共混物,测定了材料的力学性能并用TEM研究了材料在不同加工温度下相结构的变化.结果表明,通过固相力化学粉碎制备的PA6/PP混合微粉,改善了PA6与PP和SBS的相容性,促进了PA6及PP的分散和与SBS的相界面结合.在微粉填充量为4%～8%(质量分数)时,材料的拉伸强度大幅度提高,扯断伸长率保持不变.加工温度变化引起材料相结构的变化对材料性能产生显著影响.在PP熔融温度下加工,PP粒子产生粘连形成链状结构,可提高材料的力学性能.

Abstract: Anovel technique to modify the morphology and thus to enhance the mechanical properties of polyamide 6(PA6)/polypropene(PP)/styrene-butadiene-styrene triblock copolymer(SBS) blends was reported. Ultra fine PA6 and PPparticles were prepared by using the pan type milling equipment and were mixed with SBSto produce blends. The phase structure of the blends was studied with TEMand the mechanical properties of the blends processed at different temperatures were also investigated. The PA6 PPco powder prepared by pan milling shows the improved compatibility and interfacial action with SBS. When the addition of PA6/PPwas 4%～8%, the tensile strength of the blends was enhanced greatly and the elongation at break changed little. With the variation of the processing temperature, phase structure of PA6/PPchanged remarkably and the PPparticles adhered to form chain structure and the performances of the blends were further promoted.
