Abstract

Most traditional adhesives applied in the wood industry are synthetic resins obtained from petroleum. However, the production of these resins raises substantial environmental issues because of formaldehyde release, which leads to detrimental impacts on both human health and the environment. In contrast, bio-based adhesives offer an eco-friendly option that is created by renewable biomass resources. These adhesives can effectively overcome the above problems. Hence, it is crucial to pay more attention to bio-based adhesives. However, the inherent characteristics of the raw materials used in the production of bio-based adhesives result in a number of limitations, including weak bond strength, poor water resistance, and susceptibility to mildew, which restrict their further applications. Most researchers have used physical and chemical methods to modify bio-based adhesives in order to improve their overall performance. The defects of bio-based adhesives, including their limited bond strength, inadequate resistance to water, and vulnerability to mildew, are summarized in this paper, and the investigation of potential modification methods on bio-based adhesives is reviewed. Moreover, we encourage the widespread use of bio-based adhesives in various fields to promote sustainable development due to their eco-friendly characters.

叙述性综述:改性生物基木材粘合剂以提高性能
木材工业中使用的大多数传统粘合剂都是从石油中提取的合成树脂。然而,这些树脂在生产过程中会释放甲醛,对人类健康和环境造成不利影响,因此引发了严重的环境问题。相比之下,生物基粘合剂提供了一种由可再生生物质资源制成的环保选择。这些粘合剂可以有效克服上述问题。因此,更多地关注生物基粘合剂至关重要。然而,生产生物基粘合剂所用原材料的固有特性导致了一系列限制,包括粘合强度弱、耐水性差和易发霉,从而限制了其进一步应用。大多数研究人员使用物理和化学方法对生物基粘合剂进行改性,以提高其整体性能。本文总结了生物基粘合剂的缺陷,包括粘合强度有限、耐水性不足和易发霉,并综述了对生物基粘合剂潜在改性方法的研究。此外,由于生物基粘合剂具有生态友好的特性,我们鼓励在各个领域广泛使用生物基粘合剂,以促进可持续发展。

期刊介绍: Coatings is an international, peer-reviewed open access journal of coatings and surface engineering. It publishes reviews, research articles, communications and technical notes. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. Full experimental and/or methodical details must be provided. There are, in addition, unique features of this journal: * manuscripts regarding research proposals and research ideas will be particularly welcomed * electronic files or software regarding the full details of the calculation and experimental procedure - if unable to be published in a normal way - can be deposited as supplementary material
