中文摘要:

便宜石油沥青和浪费聚乙烯(WPE ) 被用作原料由合作碳化方法和 mesophase 沥青的形成的机械化准备 mesophase 沥青也被调查。极化的显微镜学,弄软点, Fourier 变换红外线的光谱学(FTIR ) 和 thermogravimetric 分析(TGA ) 被用来描绘并且分析 mesophase 沥青的性质和结构。当 1-2  wt% WPE 被增加,热聚合准备的 mesophase 沥青(MP1-450-4 和 MP2-450-4 ) 的性质是优秀的时,结果证明修改沥青的碳化收益高。而且当处理温度在 420  °C 上面时,修改沥青的 mesophase 发展可以百分之百是全部 and,优化质地 mesophase 罐头形式。在 WPE/petroleum 沥青的合作碳化期间,很多 naphthenic 结构和甲又桥可以被产生,它能改进获得的 mesophase 沥青的性质。

英文摘要:

The low-cost petroleum pitch and waste polyethylene (WPE) were used as raw materials to prepare the mesophase pitch by co-carbonization method and the forming mechanization of mesophase pitch was also investigated. Polarized microscopy, softening point, Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) were used to characterize and analyze the properties and struc- ture of the mesophase pitch. The results showed that the carbonization yield of the modified pitch was high when 1-2 wt% WPE was added and the property of mesophase pitch (MP1-450-4 and MP2-450-4) prepared by thermal polymerization was excellent. Moreover, when the treatment temperature was above 420 ~C, the mesophase development of the modified pitch may be entire and 100% streamline texture mesophase can form. During the co-carbonization of WPEJpetroleum pitch, a large number of naphthenic structures and methylene bridges may be generated, which can improve the properties of the obtained mesophase pitch.
