【摘要】 用聚乙二醇(PEG)和自行合成的聚醚酰胺(PEA)、聚醚酯(PEET)作为抗静电剂,分别与聚酰胺-6共混,制得了抗静电聚酰胺-6切片和薄膜。用毛细管流变仪、锥板粘度计,光学显微镜、差示扫描量热仪等研究了这几种改性聚酰胺-6的流变性和形态结构。从改性剂的性质、用量、测定温度和切变速率等因素对流变性和形态的影响,找出了不同改性剂影响共混物流变性的规律。用壁面润滑机理对共混物的流变行为进行了解释。静电半衰期的测试结果表明,这三种抗静电剂在220℃、68%相对湿度下都有良好的抗静电效果(在添加量为1～10%之间,共混物的静电半衰期为1～3 s)。本文的实验结果为抗静电聚酰胺-6纤维的生产提供了工艺依据。更多还原

【Abstract】 The polyethylene glycol (PEG), together with author’s laboratorysynthesized polyetheramide(PEA) and polyetherester(PEET), are usedas three different antistatic agents and mixed respectively with PA-6to form antistatic PA-6 chips and films. The rheological property andmorphological structure of these modified PA-6 are studied with Instron3211 Rheometer, cone and plate viscometer, optic microscope and Perkin-Elmer DSC-Ⅱ. Through the elucidation of the effects of such factorsas modifier’s properties, adding quantity, testing temperature and shearrate on the blend’s rheological property and morphology, the authorsfound out the regularity expressing the influences of different modifierson the blend’s rheological behavior which can be explained by smoothmechanism of capillary surface. The determinations of electrostatichalf life period show that under. 220℃ and R. H. 68%, all these threeantistatic agents exhibit good antistatic effect (when adding quantityis about 1-10%, the half life period is 1-3 sec.). The experimentalresults obtained by the authors may provide some technological basisfor commercial production of antistatic PA-6 fibre.更多还原
