乘用车内饰零部件对车内挥发性有机化合物浓度的贡献研究
Contributions of interior materials to VOC concentrations in passenger cars
摘要：
依据质量平衡原理提出了一种实验方法，通过改变车内散发源数量，结合整车浓度的变化来判断各内饰零部件对车内挥发性有机化合物（VOC）浓度的贡献。以一辆真实的车为例，将车内的重点零部件逐一移出车外，测试了零部件移出前后车内VOC浓度的变化，据此筛选出VOC的主要贡献源。结果表明：在测试的10种零部件中，座椅总成是最重要的污染来源，对苯、甲苯、二甲苯、乙苯和苯乙烯的浓度贡献均为最大；除了表面的零部件以外，其他材料如胶类物质对污染贡献同样很大，要给予重视。
Abstract：
Proposes an experimental method based on the mass balance theory. Combined with the change of the concentration in the whole vehicle, judges the contribution of interior materials to the concentration of the in-vehicle volatile organic compound (VOC) by changing the number of emission sources in the vehicle. Taking a real vehicle as a case, removes the key interior materials from the vehicle, and measures the VOC concentration variation during this process to determine the main emission sources. The results show that among the ten parts tested, the seat assembly is the largest contributor to the VOC concentration including benzene, toluene, xylene, ethylbenzene and styrene. In addition to the surface parts, the adhesives are the important sources for interior pollutants as well, which should be paid attention seriously.
