摘要:
为了提高苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)/废橡胶粉复合改性沥青的综合性能,同时解决常规胶粉掺量造成的高粘度和相容性问题,利用单因子实验和对废胶粉进行接枝处理,研究不同工艺及其因素对沥青性能的影响.研究得出低掺量接枝胶粉能有效解决高粘度和离析问题,最优配方为:SBS掺量质量分数25%,接枝胶粉掺量质量分数15%,溶胀剂掺量质量分数4%,稳定剂掺量质量分数16%.
Abstract:
To improve the performance of SBS/Waste rubber powder modified asphalt,and resolve the issue of high viscosity and compatibility that caused by conventional rubber powder content at the same time,we studied the influence of different processes and factors on asphalt performance by the single factor experiment and crumb rubber grafting.The results show that the low amount of grafted rubber powder can effectively solve the problem of high viscosity and segregation. The optimal formula is SBS of 25%,grafted crumb rubber of 15%,sweller of 4% and stabilizer of 16%.
