摘　　要：介绍了一种简易可行的汽车内饰涂料涂层挥发性有机化合物散发量的测定方法,即试验箱-热解吸-气相色谱法,该方法选择合适的环境试验条件(如温度、湿度)进行材料的挥发试验,然后用TenaxTA吸附管定量采集挥发的挥发性有机化合物,经气相色谱分析,以甲苯为等当物、总碳量来表征挥发性有机化合物散发量,能有效评价材料在实际使用状态下的散发性。方法的精密度良好,重复性能控制在15%以内。另外,应用该方法测试了5种内饰涂料的挥发性。A brief and available test method , chamber - TD - GC method was described for the determination of emission of automobile interior materials coatings layer in this article. Suitable temperature and humidity were confirmed for the release experiment of materials. By Tenax TA sorbent sampling and TD - GC analysis, the total carbon content of VOC of materials is computed as toluene equivalent. By this means, we can reasonably valuate the emission character for materials in practice use. The precision of this method is receptive, reproducibility is below 15 percent. In addition, five coating layer samples were tested by this method.
