| 摘 要： | 优选沥青顺酐化制备工艺;以顺酐转化率为指标,以反应温度、顺酐浓度和搅拌速率为考察因素,采用正交试验法优选最佳制备工艺;温度为160℃,浓度为2 g顺酐/100 g沥青,搅拌速率为200 r/min时顺酐转化率最高;顺酐转化率只与反应温度有关,与顺酐浓度和搅拌速率无关。

| Abstract: | To optimize preparation technology of maleic anhydride modified asphalt. The preparation technology was optimized by orthogonal experiment. With the maleic anhydride conversion as evaluation index, the influence of factors such as reaction temperature, maleic anhydride concentration and stirring speed was investigated. The optimization experiments showed that the excellent result was obtained with the condition： 160℃ reaction temperature, 2 g maleic anhydride per 100 g asphalt and 200 r/min stirring speed. The reaction temperature had significant effects on the maleic anhydride conversion, while maleic anhydride concentration and stirring speed had little influence on maleic anhydride conversion. |
