YE CHAOYU, YANG TIANTIAN, WANG SHUAIQI, et al. The Influence of Amine Copper Quant Addition Amount and Phenol Formaldehyde Resin Content on the Properties of Oriented Strand Board. [J]. Chinese journal of wood science and technology, 2024, 38(6): 32-38. DOI: 10.12326/j.2096-9694.2024071.
oriented strand board (OSB) was made by adding amine copper quant (ACQ) and phenol formaldehyde resin (PF) in order to investigate the effects of ACQ additions (2
4
and 6 kg/m
3
) and PF additions (8% and 10%) on the physical
mechanical
and preservative properties of OSB. The study revealed that the physical and mechanical properties of the OSBs achieved the requirements of OSB/4 class boards in the GB/T 41715—2022 “
Oriented Strand Board
”
although these property values decreased as
the amount of preservative increased. Meanwhile
the addition of ACQ preservative improved the preservative properties of OSB. When the PF and ACQ content was at 10% and 6 kg/m
3
respectively
the average mass loss rate of the samples after 12 weeks of infection by brown rot fungus was finally reduced to 1.72%
which was only 22.7% of the control samples. The results of average mass loss rate and morphological analyses indicated that the physical encapsulation of PF and the synergism of ACQ enhanced the preservative properties of the samples. This study added data to enhance the understanding of the physical
mechanical
and preservative properties of OSB
specifically regarding improvements in durability and long-lasting utilization.
