摘要

为降低人造板基材异味对饰面板产品气味的影响，在装饰纸浸渍用无醛胶黏剂中添加不同质量分数（0.25%、0.50%、0.75%、1.00%）的香料，赋予装饰纸香味，探究香料添加量对无醛装饰纸饰面人造板香料缓释性能及表面性能的影响。采用傅里叶变换红外光谱分析仪（FTIR）、电子扫描显微镜（SEM）分别对浸渍胶黏剂、装饰纸的化学成分和装饰纸表面形貌进行测试和表征。结果表明：无醛装饰纸饰面人造板香料缓释性能较好，室温条件下90 d以后仍能释放出香味；香料与胶黏剂的相容性较好，未影响浸渍胶黏剂自身的性能。无醛装饰纸胶膜对香料粒子有适度的封闭作用，这有利于实现香料的缓释；同时饰面人造板的表面结合强度、表面耐水蒸气、表面耐污染腐蚀性能（丙酮）均达到GB/T 15102—2017《浸渍胶膜纸饰面纤维板和刨花板》的相关指标要求。

Abstract

In order to reduce the peculiar smell of the wood-based panels, various contents (with ratios of 0.25%, 0.50%, 0.75%, 1.00%) of aromatic compound were added into the formaldehyde-free adhesive to prepare the formaldehyde-free decorative paper, which endowed the decorative paper with fragrance. The effects of different aromatic contents on the slow-release performance and surface properties of the formaldehyde-free decorative paper surfaced wood-based panels were investigated. The chemical composition of impregnated resin and the surface morphologies of decorative paper were tested and characterized by the Fourier infrared spectroscopy (FTIR) and electron scanning microscope (SEM). The results showed that the aromatic sustained-release performance of formaldehyde-free decorative paper veneer wood-based panels was fairly good. The fragrance released from the testing panels has been detected after 90 days at the room temperature. The aromatic compound was compatible with the adhesive. It did not affect the properties of the impregnated adhesive. The formaldehyde-free decorative paper adhesive film had a moderate sealing effect on aromatic particles, which contributed to the slow-release of fragrance. At the same time, the properties of the surface bonding strength, surface resistance to water vapor, and surface anti-pollution (acetone) of the decorative surfaced panels met the requirements of the standard GB/T 15102—2017 of ",Surface Decorated Fiberboard and Particleboard with Paper Impregnated Thermosetting Reins,".
