摘    要:尼龙1010是我国首创的一种性能优良的工程塑料,为提高其干戍 低温冲击韧性,用Brabender PLE331型塑化仪制备了PA1010/MGEPR共混物,讨论了配料方式,MGEPR用量,丁基橡胶用量,螺杆转速等对共混物冲击强度,拉伸强度等力学性能的影响,结果表明,如采用PA1010/MGEPR(2)和PA1010/MGEPR(4)共混体系,则冲击强度较PA1010有明显提高,当螺转速为37r/min-47r/min时,混合效果较好,当丁基橡胶为乙丙橡胶(EPR)含量的10%(质量)时,共混物的冲击强度优良。

关 键 词:尼龙1010  乙丙橡胶  马来酸酊接枝乙丙橡胶  共混物  力学性能

Abstract:PA1010 is a very useful commercial enginieering plastic. Its application was limited in some respects for the lack of toughness in low temperature and drying state. For this reason , PA1010/MGEPR blends were prepared by means of Brabender PLE331 type rheometer. The mechanical properties of PA1010/MGEPR blends were studied. The experiment results show that, the tensile strength ,elastic modulus decreases with increasing EPR and MGEPR content at given temperature. The mechanical properties of PA1010/MGEPR blends were better than that of PA1010/EPR blends. The impact strength of PA1010/MGEPR blends increases with increasing in the MGEPR content.
Keywords:PA1010  ethylene  propylene rubber(EPR)  maleic anhydrade grafted EPR(MGEPR)  blends
