摘要
以高密度氧化聚乙烯蜡(OPE)为润滑剂,使用10孔喷丝板,熔融纺丝法制备超高分子量聚乙烯(UHMWPE)/高密度聚乙烯(HDPE)/纳米SiO2共混物纤维束。利用表面质量、力学性能和结晶度等性能参数分析纺丝组件温度、计量泵转速、卷绕速度和热牵伸温度对共混初生丝束和共混纤维束的影响。结果表明,随着纺丝组件温度的提高,纤维的力学性能呈先升高后下降的趋势,在组件温度为310℃时取得最大值;当计量泵转速为2r/min,卷绕速度1m/min时,初生丝表面质量最优,纤维的拉伸强度最高;热牵伸温度为90℃时,纤维的结晶度和拉伸强度取得最大值。
Abstract
Used high density oxidized polyethylene (OPE) wax as lubricant and 10 well spinneret,ultrahigh molecular weight polyethylene (UHMWPE)/high density polyethylene (HDPE)/nanometer SiO2 blend fiber bundles were prepared by melt spinning method.The effects of the spinning module temperature,metering pump speed,winding speed and hot draft temperature on the fiber bundles were analyzed by using surface quality,mechanical properties and crystallinity.The results shown that the mechanical properties of the fibers increased first and then decreased with the increase of the temperature of the spinning components,and reached the maximum value when the temperature of the components was 310℃.When the speed of metering pump was 2rpm and the winding speed 1m/min,the surface quality of raw silk was the best and the tensile strength of the fiber was the highest.When the hot draft temperature was 90℃,the fiber's crystallinity and tensile strength reached the maximum.
