摘要:沥青路面已经广泛应用在道路工程,但在沥青混凝土的生产的这个过程中需要使用大量的石材和石油沥青,而且在其高温生产施工的过程中也会产生大量的有害气体。为了能够寻找一类能够代替或者部分代替石油沥青的物质,从而既可以节能环保也能够降低生产成本的目的;本文主要在生物沥青中添加废旧聚氨酯硬泡,经过高速剪切后加入一定量的MDI,提高其高低温性能,以达到道路铺设所要求的标准。结果表明对生物沥青改性较好的是聚氨酯醇解产物,当添加量为10%-20%时反应最为充分,而且从红外图谱上可以看出此时酯交换反应也是比较明显的,从光学显微图上也可以得出此时产物混合的是最为均匀,产物的各项性能都比较良好。20476

Study of the scrap rigid polyurethane foam Modified Biobinder
Abstract Asphalt pavement has been widely used in road works, but in the production of asphalt concrete this process requires the use of large amounts of stone and asphalt, but also produces large amounts of harmful gases produced during the construction of its high temperature. In order to be able to find a class can replace or partially replace petroleum asphalt material, so both can reduce the energy saving purpose production costs; This paper added in biological waste asphalt polyurethane foam, after a certain amount of high shear MDI improve its high temperature performance, paved road to reach the standard required. The results show that the modified bitumen biological alcohol solution is preferably a polyurethane product, when added in an amount of 10% -20% response most adequate, but can be seen from the IR spectrum at this time the transesterification reaction is more evident from the optical micrographs can draw on at this time is the most uniform product mix, the properties of the product are relatively good.
