摘　　要：【目的】为了探究贴面处理对中纤板气味释放浓度和强度的影响,比较分析贴面处理后的中纤板与其素板的TVOC及各组分的气味浓度和强度的差异。【方法】采用1 m3气候箱法对三聚氰胺浸渍纸贴面中纤板及其MDF素板进行气体采样,利用气相色谱-嗅闻-质谱联用仪确定气味特征化合物。【结果】三聚氰胺浸渍纸贴面中纤板的气味总质量浓度比其MDF素板降低了21. 06%;贴面处理后板材释放的芳香烃、醛酮类气味特征化合物质量浓度分别增加了16. 88%、3. 08%,酯类、烯烃类、醇类和无气味化合物质量浓度分别降低了7. 74%、4. 34%、0. 20%和7. 68%;三聚氰胺浸渍纸贴面中纤板气味特征化合物释放的种类比其MDF素板增多,但其气味强度均比较弱;气味特征化合物的气味分为苦味、焦味糊味、清香味、烤甜味、芳香味、青草味这6种类型;邻苯二甲酸二丁酯、癸醛、2-乙基-1-己醇、苯在贴面与未贴面的板材气味释放中均被检测到,且在素板中的质量浓度、气味强度均要高于三聚氰胺浸渍纸贴面中纤板中的质量浓度、气味强度; MDF素板经过贴面处理后,气味类型虽然增加,但气味强度均属于稍可察觉(气味等级≤2),对板材的整体气味强度贡献不大。【结论】三聚氰胺浸渍纸贴面会抑制气味特征化合物的释放,降低其质量浓度和气味强度,且同一种气味特征化合物的质量浓度会在一定程度上影响其气味强度的大小。[Objective]This paper aims to study the effects of melamine faced treatment on odor concentration and intensity, and the difference of TVOC and components between melamine faced MDF and MDF.[Method] Melamine faced MDF and its control MDF were sampled by 1 m^3 climate chamber, and odor-characteristic compounds were determined by gas chromatography-olfactometry-mass spectrometry.[Result] The results revealed that the total odor mass concentration of melamine faced MDF decreased by 21.06% compared with the control. After melamine paper overlaying, the mass concentration of arenes and aldehyde ketones increased by 16.88% and 3.08%, respectively, while the mass concentration of esters, alkenes, alcohols and odorless compounds decreased by 7.74%, 4.34%, 0.20% and 7.68%, respectively. More types of the odor-characteristic compounds were given off from overlaid MDF than its control, but its odor intensity was relatively weaker. The ordor of odor-characteristic compounds can be classified as bitter, charred, fragrant, roasted sweet, aromatic, and grassy smells. Dibutyl phthalate, decanal, 2-ethyl-1-hexanol and benzene were detected in both boards. In addition, the mass concentration and odor intensity of the control were higher than the overlaid MDF. Although the types of odor increased after overlaying, the odor intensity was somewhat perceptibile (odor level ≤2) and contributed little to the overall odor intensity of the board.[Conclusion] The odor-characteristic compounds, their mass concentration and odor intensity were inhibited by the melamine impregnated paper. The mass concentration of the same odor-characteristic compound will influence the odor intensity to some extent.
