摘 要：本論文就芳綸抄紙工藝中芳綸短切纖維與芳綸漿粕的配比、分散劑用量、分層抄造技術用于芳綸紙制漿造紙的效果及熱壓用于芳綸原紙的加工效果進行初步探討。實驗結果表明，當芳綸短切纖維與芳綸漿粕的配比為1：1.5左右時，所抄造紙頁的抗張強度、撕裂度、勻度最好；在保持配比不變的情況下，分散劑PEO的加入可以有效的改善漿料的分散效果；隨著PEO加入量的逐漸增加，漿料的分散效果逐漸增加，在超過0.15%時，其分散效果反而逐漸減少，PEO的用量在0.15%左右時，所抄送紙頁的抗張強度、撕裂度、勻度最好；分層抄造的芳綸原紙比一次抄造的芳綸原紙的抗張強度和撕裂度高；在分析了芳綸原紙的熱壓工藝后，結果表明，熱壓后的芳綸紙的厚度減少，抗張強度增加但撕裂度減少。

Abstract: This article introduces the study of the effect of the matching between Aramid fiber and PPTA、PEO dispersant、hierarchical copy made in the pulping and papermarking of aramid paper and the results of hot pressing used for aramid paper. The experimental results show that when the matching between Aramid fiber and PPTA is 1:1.5 more or less,the tensile strength、tear and formation of aramid paper is the best.Not become the matching between Aramid fiber and PPTA, PEO dispersant can be to effectively improve the effectiveness of the scattered; with the increase of Peo dispersant joining, the effect of scattered is increasing, while the used of PEO dispersant is 0.15%, the tensile strength、tear and formation of aramid paper become the best. The tensile strength and tear of aramid paper that papermarking for two is strong than the aramid paper which is papermarking for one. The experimental results show that the thickness of aramid paperis and tear is to decrease,but the tensile strength of aramid paperis is to stronger.
