| 摘 要： | 可膨胀石墨作为典型的物理膨胀阻燃剂具有瞬间膨胀力强、无滴落、短时间内将火熄灭等优点.为了合成高膨胀性能,较高起始膨胀温度的可膨胀石墨,实验考察了KMnO4用量、H2SO4浓度及其用量、反应温度等因素对可膨胀石墨的起始膨胀温度及膨胀容积的影响.根据L9(34)正交实验结果筛选出了制备高起始膨胀温度及高膨胀性能的可膨胀石墨...

| Abstract: | As one kind of physical dilatable flame retardant,expandable graphite(EG) have the advantages of expanding in a short time,no dripping when burned and extinguishing the fire instantly at the beginning.To prepare EG with high dilatability and high initial temperature,the influence of various factors on dilatability of EG was detected including the amount of KMnO4,mass concentration and dosage of H2SO4,reaction temperature and so on.Feasible conditions were obtained according to the result of L9(34) experimen... |
