摘要

主要对乙烯-四氟乙烯共聚物 (ETFE)、聚全氟乙丙烯(FEP)、聚偏氟乙烯(PVDF)、全氟磺酸树脂(PFSA)和全氟羧酸树脂(PFCR)这几种典型含氟树脂的加工流变行为和线性粘弹性进行了综述。FEP高速挤出时稳定流动区非常窄

并且进行模型拟合时发现其剪切流动行为符合Carreau模型。ETFE为热流变简单高分子

其剪切粘度、拉伸粘度、挤出胀大和动态模量等流变函数均可进行时温叠加。在低剪切速率下

PVDF熔体表现出牛顿流体行为;在高剪切速率下

PVDF熔体呈现出剪切稀化现象。PFSA和PFCR熔体的表观黏度随剪切速率、温度的升高而降低

流动曲线显示该熔体属于假塑性流体。

Abstract

In this paper we discuss the research on the rheological behavior of several typical fluoropolymers

such as Polyvinylidene fluoride (PVDF)

fluorinated ethylene propylene copolymer (FEP)

ethylene tetrafluoroethylene alternative copolymer(ETFE) and perfluorosulfonyl fluoride resin(PFSF). FEPs possess quite narrow stable flow region and very poor processability

results were fitted by using Carreau equation. ETFE is thermo rheology simplicity polymer

and ETFE holds wider stable region and superber processability. At very low shear rates

PVDF melt was Newtonian fluid

however it was non-Newtonian fluid at higher shear rates

and its melting viscosity decreased with the increase of shear rates. The apparent viscosity of PFSR and PFCR melt is decreased with increase of shear rate and temperature

and non-Newtonian index is less than 1 in the range of test temperature. The viscosity curves indicates that the PFSR and PFCR melt exhibits a pseudo plastic nature.
