芳纶纤维表面改性及其对芳纶纸力学性能的影响
Modification of aramid fiber and its effect on the mechanical properties of aramid paper
摘要
Abstract
The aramid short fiber was firstly modified with chlorine acid or acetic anhydride under different conditions respectively ,then mixed with fibrids to manufacture aramid paper and finally effect of different treatment process on the mechanical properties of aramid paper was discussed .Results show that aramid paper have better mechanical properties at the chlo-rine acid concentration of 2% ,processing time of 10min and processing temperature of 50 ℃ . T he tensile index and tear index aramid paper had increased 63 .8% and 21 .4% respectively when the fiber was modified by acetic anhydride at the concentration of 100% .In addition , tensile index and tear index of aramid paper had increased by 84 .7% and 38 .4% w hen the ar-amid fiber was soaked 1 min in acetic anhydride and treated 3 min in methanol .关键词
