摘要
研究了超高相对分子质量聚丙烯(UHMWPP)的加入对超高相对分子质量聚乙烯(UHMWPE)冻胶体系粘性行为、非牛顿指数、结构粘度指数的影响。结果表明:UHMWPP在UHMWPE/UHMWPP共混体系中起到了润滑剂的作用,使体系的表观粘度降低,非牛顿指数升高,结构粘度指数下降。其中,UHMWPP添加量为5%时,冻胶体系的可纺性最佳。
The influence of UHMWPP （uhra-high molecular weight polypropylene） on the rheological behavior of UHMWPE （ultra-high molecular weight polyethylene） gel system was studied, as were the non-Newtonian index and the structural viscosity index. The results showed that UHMWPP plays a role of lubricant, which could decrease the apparent viscosity and structural viscosity index and increase the non-Newtonian index. And UHMWPE/5 % UHMWPP gel system exhibits the best spinnability.
