Abstract

A thin and porous non-flammable wiper was prepared by phosphorus acid solution treatment and subsequent oven annealing. The H3PO3 treatment improved flame retardancy of wiper paper to nonflammable level. Thermogravimetric analyses showed that residues increased to 50% at 700℃, which means this treatment helps dehydration of the cellulose chain and promotes the formation of char-like structures during the burning. FT-IR and X-ray photoelectron spectroscopy showed that some of the added H3PO3 could react with the functional groups of the cellulose chain. The reacted H3PO3 components promote dehydration of the cellulose components and the formation of a char-like structure and improve the flame retardancy of the wiper paper.

매우 얇고 다공성 비인화성 와이퍼 용지를 아인산 수용액 처리에 의해 준비되었다. H3PO3 처리는 와이퍼 용지의 난연성을 불연성 수준으로 개선시켰다. 열중량 분석 결과 700℃에서 잔량이 50%까지 증가했다. 이것은 본 실험과 같은 아인산 처리가 셀룰로오스 사슬의 탈수를 돕고, 연소중에 차르(char)와 유사한 구조의 형성을 촉진한다는 것을 의미한다. FT-IR과 X선 광전자 분광학에서는 H3PO3의 일부분은 셀룰로오스 사슬의 작용기와 반응하는 것으로 보였다. 반응한 아인산은 셀룰로오스의 체인의 탈수를 촉진하고, 차르와 같은 구조의 형성을 도와 와이퍼 용지의 난연성을 향상시킨다.
