Wood composite industries mainly use phenolic-based adhesives in the production of exterior grade plywood, oriented strand boards and particle boards. Phenolic adhesives are made from two main components: phenol and formaldehyde, which are both produced from petroleum resources. Cost-effective substitution of these raw materials with environmentally safe and sustainable biomaterials would benefit manufacturers of wood composites and resins, as well as consumers. The goal of the proposed project is to modify two natural biopolymers to formulate an adhesive that is entirely made of sustainable raw materials. In particular, an engineered starch-based polymer and lignin will be used to develop a bio-based adhesive. The starch-biopolymer will be modified to become a suitable alternative to the formaldehyde component of phenolic resin, whereas lignin (an abundant and underutilized side stream of forest and bioenergy sectors) will be investigated as a substitute for phenol. This short-term project will focus on investigating modification routes that improve the reaction of these two natural biopolymers in the production of environmentally sustainable phenolic resin. Subsequent projects will optimize the modification processes and formulate a phenolic adhesive using the 100% bio-based resin developed herein.

木材复合工业主要使用酚醛类胶粘剂生产外立面胶合板、定向刨花板和刨花板。酚醛胶粘剂由两种主要成分制成：苯酚和甲醛，这两种成分都是从石油资源中产生的。用环境安全和可持续的生物材料以成本效益高的方式替代这些原材料，将有利于木材复合材料和树脂的制造商以及消费者。拟议项目的目标是修改两种天然生物聚合物，以形成完全由可持续原材料制成的粘合剂。特别是，一种工程淀粉基聚合物和木质素将被用于开发一种生物基粘合剂。淀粉-生物聚合物将被改性成为酚醛树脂甲醛成分的合适替代品，而木质素（森林和生物能源部门丰富且未充分利用的侧流）将被研究作为苯酚的替代品。这个短期项目将重点研究改善这两种天然生物聚合物在生产环境可持续酚醛树脂中的反应的改性途径。后续项目将优化改性工艺，并使用本文开发的100%生物基树脂配制酚醛粘合剂。
