【摘要】 通过溶胀测试,研究了温度、时间、苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS) 结构对溶胀行为的影响。结果表明,在高于SBS的PS玻璃化转变温度时,SBS的溶胀较明显。 线型SBS较星型SBS更容易溶胀,溶胀成分密度接近芳香分的密度。更多还原

【Abstract】 The swelling behavior of SBS in asphalt play a very important role in processing and properties of SBS modified asphalt. The swelling behavior of SBS in asphalt was studied in this paper by means of swelling measurement. The results showed that the swelling speed of SBS increased with temperature, especially around the melting temperature of SBS. The linear SBS swelled more easily than the star-branch SBS under the same condition. The density of swollen part was near density of aromatics in asphalt.更多还原
