摘要
为促进废物利用及绿色道路材料开发,将木屑液化后进行树脂合成,再将合成的热塑性酚醛树脂加入到路用基质沥青中制备生物沥青。以树脂掺量、制备温度、制备时间、发育温度为影响因素,进行四因素三水平正交试验,考察生物沥青针入度、延度、软化点、黏度的变化。结果表明,制备时间对生物沥青的性能影响最显著;制备温度和发育温度次之;树脂掺量影响最小。当制备温度为140℃、树脂掺量为10%(质量分数)、制备时间为80min、发育温度为160℃时,生物沥青各项指标最好。
Abstract
To promote the recycling of waste and development of green road material,liquefied wood was made into the synthetic resin.And then the synthetic resin was added to the road asphalt for the preparation of bio-asphalt.According to the synthetic resin content,preparation temperature,preparation time and developing temperature,orthogonal tests were designed to determine the reasonable ratio of raw material and the technology condition by penetration,ductility,softening point and viscosity.Test results and analysis indicated that the preparation time was the most significant factor on the performance of bio-asphalt.The preparation temperature and development time were second,the influence of synthetic resin content was minimum.When the preparation temperature was 140℃,the synthetic resin content was 10%,the time was 80min,the development temperature was 160℃,the performance of bio-asphalt was relatively best.
