摘　　要：【目的】探索漆饰贴面刨花板VOCs及气味释放特性,分析环境因素对板材VOCs和气味平衡状态释放组分的影响,为人造板气味研究提供基础性数据。【方法】以硝基涂料贴面刨花板和水性丙烯酸涂料贴面刨花板为研究对象,建立单因素试验方案,使用气相色谱-质谱/嗅觉测量技术对板材在不同环境条件下释放VOCs和气味情况进行分析,确定2种漆饰贴面刨花板特征气味物质和可能性来源的同时探索环境因素的影响,并对2种板材的VOCs和气味释放情况进行综合评价。【结果】相比硝基涂料贴面刨花板,水性丙烯酸涂料贴面刨花板释放TVOC浓度低、气味化合物数量少且总气味强度低,2种板材均以芳香族化合物和酯类化合物超标最为严重。硝基涂料贴面刨花板主要气味来源为芳香族化合物、酯类和醇类物质,水性丙烯酸涂料贴面刨花板主要气味来源为芳香族化合物和醇类物质。不同气味特征化合物的气味强度与其质量浓度没有直接相关性,但同一种气味特征化合物的质量浓度在一定程度上影响其气味强度大小。随着空气交换律与负载因子比增加,硝基涂料和水性丙烯酸涂料贴面刨花板TVOC释放量和总气味强度降低。随着温度升高,硝基涂料和水性丙烯酸涂料贴面刨花板TVOC释放量和总气味强度增大。随着湿度增加,硝基涂料贴面刨花板TVOC释放量和总气味强度增大,而水性丙烯酸涂料贴面刨花板TVOC释放量和总气味强度减小。硝基涂料贴面刨花板气味物质浓度占TVOC浓度的比例随温度和相对湿度升高而增加,水性丙烯酸涂料贴面刨花板气味物质浓度占TVOC浓度的比例随温度和相对湿度升高而减小,空气交换律与负载因子比对气味物质浓度占TVOC浓度的比例影响不大。【结论】气相色谱-质谱/嗅觉测量技术可作为人造板及家具材料气味研究的手段。相比硝基涂料贴面刨花板,�【Objective】This study was carried out to explore the release characteristics of VOCs and odor from lacquer veneer particleboards,at the same time,analyze the influence of environmental factors on the components of VOCs and odor in the equilibrium state.Two kinds of lacquer Fraxinus mandshurica veneer particleboards were analyzed by gas chromatography-mass spectroscopy/olfactometry in this research.The emission of VOCs and odors from different lacquer veneer particleboards was compared,and the basic data were provided for further odor research.【Method】This paper established a single factor experiment matched to the appropriate environmental conditions to analyze the release rule of VOC and odor from nitrocellulose lacquer veneered particleboards and water based acrylic lacquer veneered particleboards under different environmental factors.On the one hand,the characteristic odor compound and their resources from lacquer particleboards were indentified.On the other hand,the effects of environmental factors on the VOCs and the odor release of lacquer particleboards were investigated.Finally,the VOCs and odor release of the two lacquer veneer particleboards were evaluated by the method of“synthetic index-olfactory evaluation method”.【Result】Compared with nitrocellulose lacquer veneered particleboard,water based acrylic lacquer veneered particleboard has a lower TVOC concentration,less odor amount and lower total odor intensity.Aromatics and esters exceeded the standard most seriously in both kinds of boards.The main components of odor emission released from nitrocellulose lacquer veneered particleboards were aromatic,esters,and alcohols,whereas,those of water based acrylic lacquer veneered particleboard’s were aromatics and alcohols.For different odorous compounds,there was no direct correlation between odor intensity and its concentration,but,for the same odorant compound,its concentration affected the odor intensity somewhat.Furthermore,with the increase of ratio of air exchange rate to loading fact
