摘要:
利用碳纳米管(CNTs)改善苯乙烯-丁二烯嵌段共聚物(SBS)改性沥青性能,在高性能沥青材料制备方面具有广泛应用前景,而制备工艺是提升其性能的重要手段。文章通过研究CNTs种类、掺量及添加方式等关键工艺对CNTs/SBS复合改性沥青性能的影响规律,提出其复合改性沥青的最佳制备工艺。结果表明:羟基化CNTs(CNTs-OH)对SBS改性沥青性能改善最佳,羧基化CNTs次之;随着CNTs-OH掺量的增加,SBS改性沥青软化点随掺量增加而增大,针入度、延度则均呈先增后降的趋势,当CNTs为0.2%时为最佳;超声振荡和直接搅拌对SBS改性沥青针入度分级体系的技术指标改善最明显,而超声振荡获得复合改性沥青低温劲度模量最小,且对劲度模量变化率无显著影响,因此超声振荡工艺为最佳方式。
Abstract:
The carbon nanotube can be used to improve the SBS asphalt properties, and has a wide application prospect in the preparation of high performance asphalt materials. The preparation technology is an important means to improve its performance. In order to study the effect of carbon nanotubes on the properties of SBS modified asphalt, this paper focuses on the effects of CNTs types, dosages and addition methods on the properties of modified asphalt. The results show that the hydroxyl-treated carbon nanotubes have the best performance improvement for SBS modified asphalt, followed by carboxyl treatment. With the increase of the amount of CNTs-OH, the softening point of SBS modified asphalt increases first, and then it is basically stable; the penetration degree and ductility increase first and then decrease, and the best when CNTs is 0.2%. Compared with the addition methods of ultrasonic and melting CNTs, the ultrasonic and agitation improve the technical index of the SBS modified asphalt penetration classification system. The mixing of the composite modified asphalt is the largest, and the ultrasonic is the second. The degree of modulus is the smallest and the value of m does not change much, so the ultrasonic process is optimal.
