摘要
本研究采用泡沫成形技术制备间位芳纶纸,重点研究了表面活性剂种类对泡沫性质及芳纶纸性能的关系。相同空气含量下,非离子型表面活性剂泡沫最稳定。在成形浓度0.4%时,Tween的泡沫成形体系所得芳纶纸的匀度指数达103。与传统湿法成形相比,实现了在节约9倍用水量的同时,大幅度提升了匀度指数。热压后,泡沫成形体系制备的芳纶纸击穿强度可达到甚至高于传统湿法成形所得芳纶纸。
The meta-aramid paper was prepared by foam forming technology in this work,and the correlation between the type of surfactants and the foam properties and aramid paper performance was investigated. The foam formed by non-ionic surfactant was the most stable with the same air content. With forming concentration of 0. 4% in the Tween foam forming system,the evenness index of aramid paper reached103. Compared with traditional wet-formed aramid paper,the evenness index was largely increased with the water consumption reduced by 9 times. After hot pressing,the breakdown strength of aramid paper prepared by foam forming system could reach or even surpass the value of traditional wet-formed aramid paper.
