Abstract

In recent times, mass timber products have encouraged renewed interest in wood as raw material for more sustainable building and construction. However, durability concerns due to wood susceptibility to biodegradation could curtail this interest. Hence, there is a need for more durable wood products in emerging structural applications including the use of preservative-treated wood for composite and mass timber products. This is particularly crucial in tropical and subtropical environments where wood products are highly vulnerable to biodeterioration. Unfortunately, preservation treatment often adversely affects other wood properties such as the surface adhesion characteristics and adhesive-bond performance. Therefore, this review focused on the adhesion characteristics of wood, the impact of preservative impregnation, and the resultant effect on adhesive-bond performance. The aim is to draw attention to the challenges with bonding preservative-treated wood, and possible areas for research targeting bonding improvements.

摘要

最近，大量木材产品激发了人们对木材作为更可持续建筑的原材料的兴趣。然而，由于木材对生物降解的敏感性，耐久性问题可能会削弱这种兴趣。因此，在新兴结构应用中需要更耐用的木制品，包括将防腐处理的木材用于复合材料和大型木材产品。这在木制品极易受到生物降解的热带和亚热带环境中尤为重要。不幸的是，防腐处理通常会对其他木材性能产生不利影响，例如表面粘合特性和粘合性能。因此，本综述重点关注木材的附着力特性、防腐剂浸渍的影响、以及由此产生的对粘合性能的影响。目的是引起人们对粘合防腐处理木材的挑战的关注，以及针对粘合改进的可能研究领域。
