摘要

定向刨花板是一种结构木复合材料，应用要求良好的物理和机械性能。为了改善定向刨花板的性能，研究了ZnO纳米颗粒的添加。然而，目前还没有关于定向刨花板效果的信息。本研究的目的是评估氧化锌纳米颗粒以两种不同百分比(0.25%和0.50%)的添加对酚醛树脂生产的定向刨花板板的物理机械性能和热压传热的影响。定向刨花板按欧洲标准生产和测试。ZnO纳米粒子的加入改善了面板的尺寸稳定性，减少了面板的厚度膨胀，同时也提高了面板的螺杆拉伸强度。加入纳米颗粒后，热压过程中的传热使热压板的温度升高得更快;另一方面，对照处理的最终温度较高。

Physical-mechanical properties and heat transfer analysis of OSB produced with phenol-formaldehyde and ZnO nanoparticles addition

Oriented Strand Board is a structural wood composite with applications that require good physical and mechanical performance. The addition of ZnO nanoparticles is an alternative that has been studied in order to improve the properties of Oriented Strand Board panels. However, there is no information about its effect Oriented Strand Board. The aim of this work was to evaluate the influence of the addition of zinc oxide nanoparticles in two different percentages (0,25 % and 0,50 %) on the physical-mechanical properties of Oriented Strand Board panels produced with phenol-formaldehyde resin and on the heat transfer during hot-pressing. Oriented Strand Board panels were produced and tested according to European Standards. The addition of ZnO nanoparticles improved the dimensional stability of the panel, reducing its thickness swelling, and also increased the screw withdraw strength. The heat transfer during hot-pressing increased the temperature more quickly on boards with nanoparticles addition; on the other hand the final temperature of the control treatment was higher.
