运用稠油降黏技术引入石油沥青降黏,将实验室自制的丙烯酸十八酯/苯乙烯/马来酸酐(ODA/SM/MAH)三元共聚物添加到基质沥青中,得到了不同温度及不同掺量下三元共聚物改性沥青的降黏效果,采用离析试验和差示扫描量热分析对三元共聚物的稳定性进行了评价.研究结果表明:三元共聚物能够有效地降低沥青的黏度,降黏效果在不同温度下和不同掺量下有所不同.三元共聚物改性沥青储存稳定性均合格,并且在不同贮存时间及不同贮存温度下储存稳定性良好.

The viscosity reduction technology employed for heavy oil was applied for asphalts. The terpolymer of octadecyl acrylate,styrene and maleic anhydride prepared in our laboratory was added to the matrix asphalt,and the viscosity reduction effect of terpolymer modified asphalt was evaluated under different temperature and different dosage. The segregation test and differential scanning calorimetry analysis were adopted to evaluate the stability of terpolymer. The results showed that the terpolymer could effectively reduce the viscosity of asphalts and the reduction was different by different temperatures and different dosage. The terpolymer modified asphalts are all satisfied with the storage stability tests at different storage time and storage temperatures.
