摘要
New acrylic rubber hollow fiber damping materials were successfully produced by drywet spinning technique. The effect of polymer concentration and blending ratio on ACM/PVC hollow fiber were investigated. The results showed that the tensile strength increased with the increase of polymer content and decreased with the decrease of blending ratio. DMA revealed that varying the size of inner diameter, the loss tangent (tan ) would change. FTIR proved certain interactions among them. In addition, the position of peak of the glass transition temperature not only shifted to a higher temperature with the increase of PVC content, but also its temperature range of tan > 0.3 was 4065 degrees C, inferring that ACM/PVC mixture is a promising damping-material. The outer skin and inner skin structure of ACM/PVC hollow fiber by SEM were different from that used in water treatment due to the differences between materials.
