The "green" production of bitumen has raised increasing interest in recent years to reduce the environmental, energy-related and petro-based concerns. Bio-oil, prepared by biomass pyrolysis, can be used as a substitute for petro-based bitumen in bitumen or bitumen-based coatings, for its similar properties of good adhesion and anti-corrosion characteristics as bitumen. Although biomass is a renewable and widespread chemical resource, its high-valued utilization is still difficult. Several studies have qualitatively demonstrated the use of bio-bitumen in practical applications. The present study investigates that adding some bio-oil to traditional bitumen to form a bio-bitumen could help improve the properties of traditional bitumen. Bio-bitumen was prepared from biomass pyrolysis oil and applied to self-adhesive and doped hot-melt sheets. Results of physical properties demonstrate that bio-bitumen is a potential substitute in bitumen coating sheet.Implications: This paper is intended to verify the effect of pyrolyzed bio-oil from wheat straw on the performance of bitumen, as well as the feasibility of application in the coating sheet. Up to now, the research on bio-bitumen is mainly in pavement bitumen. In the present research, bio-bitumen was applied to the coating sheet in different proportions. Interestingly, the prepared coating sheet exhibited higher adhesion. Other performances, such as temperature stability, mechanical strength and temperature flexibility of coating sheet showed improvement in the presence of bio-oil, which indicated the suitability of bio-oil in coating sheet bitumen.

使用生物质热解油的沥青涂料的性能。

近年来，沥青的“绿色”生产引起了人们越来越多的兴趣，以减少对环境，能源和石油等方面的担忧。通过生物质热解制备的生物油可以用作沥青或沥青基涂料中石油基沥青的替代品，因为它具有与沥青相似的良好附着力和抗腐蚀特性。尽管生物质是一种可再生且广泛使用的化学资源，但其高价值利用仍然很困难。多项研究定性地证明了生物沥青在实际应用中的使用。本研究调查了在传统沥青中添加一些生物油以形成生物沥青可以帮助改善传统沥青的性能。由生物质热解油制备生物沥青，并应用于自粘和掺杂的热熔片材。物理性质的结果表明，生物沥青是沥青涂料的潜在替代品。启示：本文旨在验证小麦秸秆热解生物油对沥青性能的影响以及在沥青中的应用可行性。涂层板。迄今为止，对生物沥青的研究主要集中在路面沥青上。在本研究中，将生物沥青以不同的比例施加到涂层片材上。有趣的是，制备的涂层片表现出更高的粘附性。在存在生物油的情况下，涂层片的其他性能，例如温度稳定性，机械强度和温度柔韧性显示出改善，这表明生物油在涂层沥青中的适用性。
