摘要
本研究并采用干-湿相转换法成功制备出HNBR中空纤维阻尼新材料,探讨了HNBR/PVC铸膜液固含量、共混比对HNBR中空纤维材料阻尼性能的影响,结果表明:当材料铸膜液固含量为22%、HNBR在HNBR/PVC共混物中含量占10%(质量分数)时,材料的阻尼损耗因子峰值最大值为0.66;初步探讨了中空气囊对HNBR中空纤维阻尼性能的影响,比较了两种不同纺丝头制备出的HNBR中空纤维的阻尼性能,纺丝头孔径尺寸较大者纺制出的中空纤维的阻尼性能更好,说明中空气囊结构有助于提高材料的结构附加阻尼。
In this paper,using the method of dry-wet phase inversion,we made been spun new HNBR / PVC hollow fibers damping material successfully. The influence of HNBR / PVC hollow fiber's damping property has been discussed which aroused by polymer concentration and blends proportion. The results show that the peak of damping reach the maximum of 0. 66 for HNBR hollow fiber when the polymer concentration is 22% and the mass content of HNBR in HNBR / PVC blends is 10%. The effects of hollow balloon on materials damping property also have been discussed initially. The damping performance of hydrogenated nitrile rubber hollow fiber prepared by two different spinning nozzle has been compared. The results show that the size of the nozzle also have a certain extent influence on the damping properties of HNBR hollow fibers materials. HNBR hollow fibers made by greater nozzle will have higher damping peak value. It shows that hollow balloon is helpful to improve the additional structure damping of materials.
