路用蔗渣木质素纤维稳定性试验研究

利用1％、3％、5％碱溶液对蔗渣纤维进行高温碱降解处理,对比不同浓度碱液处理对蔗渣纤维的增强和降解程度,并与聚酯纤维、聚丙烯晴纤维进行高温吸油性、高温耐热与抗吸湿性对比试验,分析几种纤维在高温与潮湿环境下的稳定性能变化,通过沥青胶浆析出率和吸湿率等性能试验研究结果对比,从界面的理论解释蔗渣纤维的吸油机理,得出沥青与蔗渣纤维保持良好吸附性的原因.试验结果发现,随着碱液浓度的增大,蔗渣纤维在高温环境下的稳定性和吸油率都具有一定的提高和改善.

Experimental study on the stability performance of road use bagasse lignin fiber

In order to inquiry the degradation and enhancement effect of different lye concentration on bagasse fiber performance,with the bagasse fiber specimens produced by lye concentration of 1%,3% and 5%,high temperature oil absorptive test,heat resistant test and hygroscopicity test were conducted with polyester fiber and polypropylene fiber,and stability performance change of different fibers under high and humid environment was analyzed.Through comparing asphalt mortar emanation rate,hydroscopicity and other test results,this paper explains the oil absorptive mechanism of bagasse lignin fiber with the interface theory,and derived the reason that the asphalt and bagasse lignin fiber maintain good adsorptivity change.It was observed that the stability and oil absorptive rate of bagasse lignin fiber under high temperature began to significantly improve by increasing the lye concentration.
