摘要
Abstract
The HClO4/CH3C00H/KMnO4 oxidation intercalation system for preparing low temperature expandable graphite was developed in this paper. To obtain the optimum conditions and the material proportion, the influence of the dosage of perchloric acid, acetic acid and potassium permanganate, reaction temperature and reaction time was studied. When the reaction was carried out at 35℃ for 60min, and the optimal mass ratio of graphite(g) , perchloric acid(mL) , acetic acid(mL)and potassium permangantate(g) was 1 : 4 : 1. 5 : 0. 15 ,the inflation volume of grapite could attain 423mL/g at 400℃. There were not any sulfur-containing reagents,so the expansible graphite did not contain sulfur.关键词
