Para-aramid paper reinforced by para-aramid and meta-aramid copolymerized fibrid and preparation process of para-aramid pape

The invention belongs to the technical field of papermaking, and particularly relates to para-aramid paper reinforced by para-aramid and meta-aramid copolymerized fibrid and a preparation process of the para-aramid paper. On the basis of para-aramid chopped fibers and para-aramid nanofibers, para-aramid and meta-aramid copolymerized fibrid is added to replace meta-aramid fibrid in the prior art, and the proportion of the raw materials is adjusted. The para-aramid and meta-aramid copolymerized fibrid contains a small amount of meta-aramid components, so that the para-aramid and meta-aramid copolymerized fibrid not only can reach considerable strength, but also can ensure enough elastic modulus. The para-aramid paper is especially suitable for manufacturing downstream product honeycomb core materials, and the performance is outstanding. 本发明属于造纸技术领域，具体涉及一种对位间位芳纶共聚沉析纤维增强对位芳纶纸及其制备工艺。本发明原料在对位芳纶短切纤维、对位芳纶纳米纤维的基础上，添加对位间位共聚沉析纤维替代现有技术中的间位芳纶沉析纤维，并调整各原料比例。其中，对位间位芳纶共聚沉析纤维中含有少量间位成分，既能够达到相当的强度，也能够保证足够的弹性模量。尤其适合下游产品蜂窝芯材的制造，性能
