摘要
介绍了加拿大冷湖原油、伊拉克巴士拉原油和南美原油三种原油在高等级道路沥青和防水沥青生产中的应用。通过实验室研究,开发出了混炼三种原油生产道路沥青的工艺路线:冷湖原油、巴士拉原油与南美原油以4:3:3比例蒸馏可以生产出性能优良的AH-90号、AH-50号高等级道路沥青。以混炼AH-90号沥青为原料,采用复合聚合物改性方法制备弹性体(SBS)改性沥青涂盖料及防水卷材。对低温柔性、耐热性等指标进行检测,均满足NB/SH/T0981—2019《防水材料用沥青》和GB18242—2008《弹性体改性沥青防水卷材》标准技术要求。为道路沥青及防水产品生产提供了新思路。
This paper introduced the application of the Cold Lake crude(Canada),the Basra crude(Iraq) and the South American crude in preparing high grade road asphalt as well as waterproofing roll asphalt.Though laboratory research,the production process of road asphalt by mixing three kinds of crude is developed.Refining the Cold Lake crude,the Basra crude and the South American crude by the ratio of 4:3:3,high grade road asphalt AH-90 and AH-50 with excellent performance can be produced.AH-90 asphalt is used to prepare elastic SBS modified asphalt membrane materials and waterproofing roll through composite polymer modification method.Performances such as low temperature flexibility and heat resistance are tested.The results meet the requirement of NB/SH/T 0981-2019 ‘Asphalt For Waterproofing Materials’ and GB 18242-2008 ‘Styrene Butadiene Styrene(SBS) Modified Bituminous Sheet Materials’.This paper provides a new idea for preparing road asphalt and waterproofing material.
