摘要
本文用Instron毛细管流变仪研究了HDPE/NBR共混体系的流动曲线、表观粘度、以及HDPE/NBR共混体系的流变特性的本质。NBR的不完全交联被认为是产生HDPE/NBR共混体系流变特性的原因。
In this paper, the rheological characteristics of HDPE/NBR blends were studied.When the amount of NBR became small, the viscosity of the blends increased sharply, indicating that smaller amount of NBR would favour entanglement with HDPE.This rheological characteristic of the blends was owing to the slightly crosslinking of NBR in blending. The mechanism of the interaction between HDPE and NBR was proposed.
