摘要

采用毛细管流变仪研究了尼龙11(PA11)与POE复合材料的流变性能

结果表明:PA11及其与POE共混体系均属于假塑性流体

引入POE和POE-g-MAH增加了共混体系的非牛顿性

且随POE-g-MAH含量的增大

共混体系的表观粘度逐渐增大.PA11与POE共混体系的粘流活化能随着剪切应力的增大而降低

说明其在高剪切应力下可在较宽的温度范围内加工成型.

Abstract

The rheological properties of PA11 and its composites with POE were studied by using capillary rheometer.The results showed that PA11 and its blend system are pseudoplastic fluids.The non-Newtonian indexes of the blend systems decrease remarkably when POE and POE-g-MAH are added in PA11.With the increase of POE-g-MAH content

the viscosities of the systems gradually rise.The viscous activation energy of PA11 and POE blends decline as the increase of shearing stress

which indicate that the PA11 and POE blend can be processed over a wide temperature at a high shearing stress.
