摘要
基于石油沥青供应量的限制和环保考虑,发展环境友好的可再生生物沥青逐渐成为关注的热点。由于生物质原料的种类和生物质重油的提炼方法对生物沥青的性能有较大影响,同时生物沥青高温易老化、低温易脆化的性能不足限制了其广泛应用。因此,深入了解生物沥青的来源、组成、结构和性能特点,并选用适宜的方法对生物沥青进行改性,对发展高性能生物沥青具有重要意义。基于此,从生物质重油的提炼工艺、生物沥青的制备特点出发,综合阐述和分析了生物质重油及生物沥青的制备工艺、组成和性能特征,并深入总结了生物沥青的改性方法和改性机理,以期为生物沥青改性技术的发展和生物沥青的广泛应用提供借鉴。
Due to the limitation of petroleum asphalt supply and environmental protection considerations,the development of environmental-friendly renewable bio-asphalt has gradually become a hot spot.The kinds of biomass raw materials and the refining methods of biomass heavy oil(bio-oil)have a great impact on the performance of bio-asphalt.At the same time,the poor performance of bio-asphalt which is easy to age at high temperatures and embrittle at low temperatures limits its wide application.Therefore,it is of great significance to investigate the source,composition,structure and performance characteristics of bio-asphalt,and to select appropriate methods to modify bio-asphalt for the development of high-performance bio-asphalt.Based on this,the preparation process,composition and performance characteristics of bio-oil and bio-asphalt were comprehensively expounded and analyzed from the aspects of the refining process of bio-oil and the preparation characteristics of bio-asphalt.The modification method and mechanism of bio-asphalt were deeply summarized in order to provide a reference for the development of bio-asphalt modification technology and the wide application of bio-asphalt.
