  • 摘要: 以中温煤焦油沥青的四氢呋喃萃取物(THFS) 对石油基质沥青进行改性, 考察了掺混量、掺混温度和不同种类交联剂对改性沥青性能的影响, 确定了THFS最佳掺混量为8%, 最佳掺混温度为135 ℃, 甲醛交联剂的最佳掺混量为0.8%, 三聚甲醛的最佳掺混量为0.2%。考察了两两和单族组分对基质沥青的改性性能, 发现重油(HS) 使得改性沥青的针入度、延度增大, 沥青烯(A) 和甲苯不溶四氢呋喃可溶物(PA) 提高感温性, 软化点升高。随着醛类交联剂的添加, 提高了改性沥青的抗老化性能; 甲基(CH3)、亚甲基(CH2) 透射峰强度逐渐变强, 770-730 cm-1、710-690 cm-1和770-810 cm-1苯环取代透射峰强度逐渐增强, 1 010-1 270 cm-1处C-O-C伸缩振动峰逐渐增强; 热解峰温向高温移动, 残炭率增加2%;改性粒子呈现一种连续的流线分布, 添加三聚甲醛的改性沥青的流线分布更加集中。
