为了解决废旧塑料改性沥青储存稳定性和低温抗裂性差等问题,采用双螺杆挤出机对废旧聚乙烯(PE)进行预处理,并将其与生物油复合制得生物油/预处理废旧PE复合改性沥青.采用离析试验、流变性能试验、荧光显微镜试验和傅里叶变换红外...展开更多 为了解决废旧塑料改性沥青储存稳定性和低温抗裂性差等问题,采用双螺杆挤出机对废旧聚乙烯(PE)进行预处理,并将其与生物油复合制得生物油/预处理废旧PE复合改性沥青.采用离析试验、流变性能试验、荧光显微镜试验和傅里叶变换红外光谱试验分析了改性沥青的储存稳定性、低温抗裂性和高温稳定性.结果表明:经预处理后的PE密度与沥青密度相近,极性基团和C=C结构...

To address the issues of poor storage stability and low⁃temperature crack resistance in waste plastic⁃modified asphalt,a twin⁃screw extruder was employed to pretreat waste polyethylene(PE)and subsequently it was combined with bio⁃oil to produce bio⁃oil/pretreated waste ...MORE To address the issues of poor storage stability and low⁃temperature crack resistance in waste plastic⁃modified asphalt,a twin⁃screw extruder was employed to pretreat waste polyethylene(PE)and subsequently it was combined with bio⁃oil to produce bio⁃oil/pretreate...
