【目的】为了降低人造板挥发性有机化合物（ VOC）的检测成本、增强可靠性，提高产品环保水平和工作效率，提出一种新型的 VOC 快速检测方法。【方法】以3层实木复合地板为研究对象，建立单因素试验方案，合理搭配各环境条件，快速采样装置与气质联用仪结合使用，对其在不同温度、相对湿度和空气交换率与负荷因子之比条件下释放的 VOC 进行检测和分析，一方面探索3层实木复合地板释放 VOC 的主要成分及释放规律，另一方面分析各环境因素对3层实木复合地板释放的 VOC 达到稳定期时浓度的影响。根据板材VOC 的释放规律，确定快速释放法在最佳环境条件下得到的 VOC 量值，同时，利用传统气候箱法表征板材自然衰减过程中 VOC 释放量值，将2种方法测得数据进行对比，分析快速检测法与传统气候箱法的相关性。【结果】芳香烃和酯类是3层实木复合地板的主要挥发性有机释放物，除了部分烷烃、烯烃和醛酮类化合物外，板材还释放少量的醚、醇和酸类化合物。在测试期间，酯类和芳香烃类化合物的质量浓度变化趋势明显。温度和相对湿度增加会使平衡时的 TVOC 释放量增大，但当温度越高，湿度对平衡条件下 TVOC 的释放量影响越小。空气交换率与负荷因子之比越小，处于稳定散发阶段的实木复合地板释放的 TVOC 浓度值越大。【结论】快速检测法和传统气候箱法测得3层实木复合地板 TVOC 释放水平趋势基本一致，并且检测物相同。随着时间的延长，TVOC 的释放量逐渐下降至稳定趋势。3层实木复合地板释放的主要挥发物酯类和芳香烃类来源于板材表面加工过程中使用涂料的有机溶剂，建议选择环保型涂料。温湿度的协同作用影响3层实木复合地板 VOC 释放量，高温高湿条件对3层实木复合地板中 VOC 的释放量有显著影响。而且，空气交

[Objective]To reduce the testing cost and enhance the research reliability and efficiency,this paper introduced a new rapid detection method for testing VOC released from three-layer parquet. The M-CTE thermal extractor was explored to analyze the effect of environmental factors about release characteristics of VOC on the stable phase and to find the correlation between the rapid detection and 1 m3 traditional climate box method. [Method]This paper established a single factor experiment matched to the appropriate environmental conditions and to analyze the release rule of VOC under different temperature,relative humidity,ratio of air exchange rate and loading factor by using rapid sampling device and GC-MS conjunctively. On the one hand,the main components and release characteristics of the VOC released from three-layer parquet were probed. On the other hand,the influence of various environmental factors on VOC under equilibrium condition was analyzed. According to the release rule,the best condition was determined by rapid detection method. Meanwhile,the 1m3 traditional climate box method was used to characterize the concentration released during the＆nbsp;process of natural attenuation. The data measured from the two kind of method was compared and the correlation was established. [Result]Results showed that： as the main components of VOC emission released from three-layer parquet, aromatics and esters had obvious changing trend in concentration. Besides some parts of alkanes,alkenes,aldehydes and ketones,small amounts of ethers,alcohols and acids were also found. Furthermore,the TVOC equilibrium concentration increased with the raise of temperature and relative humidity,but the higher the temperature,the less impact of humidity on it. Ratio of air exchange rate and loading factor had remarkable effect on TVOC emissions under high temperature and high moisture condition,the smaller the ratio of air exchange rate and loading factor,the larger the TVOC concentration were found from three-layer parquet in the s
