摘要
环氧树脂因其优异的力学和化学性能在诸多领域得到了广泛的应用.环氧聚合物以强交联和醚基为主骨架,具有高强度和高耐久结构,不可生物降解,故对聚合物和复合材料的回收利用提出了挑战.传统的环氧树脂回收方法存在高能耗和使用有毒化学物质的缺点,为了满足复合材料工业资源需求、减少环氧树脂废弃物对环境的影响,急需开发可持续的回收方法.综述了环氧树脂的传统回收方法及生物降解方法的研究进展,讨论通过生物基方法回收环氧树脂存在的问题.需进一步加强对可生物降解环氧树脂和生物增强材料的研究,探索和优化生物基环氧树脂的回收方法,促进绿色生态工业和循环经济的发展.
Abstract
Epoxy resins are highly valued for their remarkable mechanical and chemical properties,and are extensively used in various applications.Epoxy polymers,characterized by their strong cross-linking and predominantly etherbased backbone,exhibits a highly rigid and durable structure,which also made their non-biodegradability raises challenges for the recycling of polymer and composites in particular.Conventional methods employed for epoxy recycling are characterized by their high energy consumption and the utilization of toxic chemicals,rendering them rather unsustainable.To cover the resource demand of the composite industry and to reduce the environmental impact of accumulated epoxy waste,there is an urgent need for the development of sustainable recycling methods.The research progress of traditional recovery methods and biodegradation methods of epoxy resin is reviewed,and the existing problems of recovery of epoxy resin by bio-based methods are discussed.It is necessary to further strengthen the research on biodegradable epoxy resins and bioreinforced materials,explore and optimize the recycling methods of bio-based epoxy resins,and promote the development of green ecological industry and circular economy.
