研究了层状双氢氧化物（LDHs）添加剂对沥青材料VOC排放的抑制作用。采用热重-质谱联用技术，得到了沥青材料挥发性化合物的离子直方图。纯沥青和LDHs改性沥青的结果表明，LDHs改性剂具有降低挥发速度和VOC排放量的潜力。还原作用对不同的分子或化合物不同。对于较小的分子，对挥发速度的降低效果显著。LDHs对致癌性较强的挥发性化合物挥发速率的影响表明，LDHs对二氯乙烷和萘挥发速率的降低幅度明显大于对正辛烷的降低幅度。研究结果表明，百分之四的LDHs是一个最佳的，在实现最佳的VOC减排的调查沥青材料。(C)2015爱思唯尔有限公司版权所有。
The effect of Layered Double Hydroxides (LDHs) additives as VOC emission inhibitor for bituminous materials was studied in this research. Ion histogram of volatile compounds from bituminous material was obtained by means of Thermogravimetry-Mass Spectrometry analysis. Results obtained for the pure bitumen and LDHs-modified bitumen show that LDHs modifier has the potential to reduce the volatile speed and amount of VOC emissions. The reduction effect varies on different molecules or compounds. The reduction effect on volatile speed is significant with smaller molecules. The effect of LDHs on the volatile speed of more carcinogenic volatile compounds shows that the reduction in speed is significantly bigger on dichloroethane and naphthalene than that on normal octane. The study findings indicate that four percent of LDHs is an optimum in achieving the best emission reduction of VOC for the investigated bituminous material. (C) 2015 Elsevier Ltd.
