【目的/意义】涂料中广泛使用的树脂衍生于石油基材料，随着化石资源的枯竭以及环境保护的需要，研发不依赖化石资源的生物基树脂对涂料的绿色发展具有重要意义。【分析/评论/进展】综述了生物基树脂的研究进展，重点介绍了利用植物油、腰果酚、木质素等生物基材料制备的新型树脂，概述了这些生物基树脂的改性方法。部分改性生物基树脂所得涂层的性能与石油基树脂所得涂层性能相当，甚至更优。【结论/展望】目前，部分生物基树脂仍面临制备工艺繁琐、成本偏高的挑战，未来可通过降低成本、优化性能，使得生物基树脂在涂料领域发挥更大作用。

［Objective/Significance］ The resins widely used in coatings are derived from petroleum-based materials. With the depletion of fossil resources and the need for environmental protection，developing bio-based resins that do not rely on fossil resources is of great significance forthe green development of coatings.［Analysis/Discussion/Progress］This paper reviews the research progress of bio-based resins，focusing on the new resins prepared using bio-based materials such as vegetable oils，cardanol，and lignin. It also summarizes the modification methods of these bio-basedresins. The performance of the coatings obtained from some modified bio-based resins is comparable to， or even better than，that of the coatings obtained from petroleum-based resins.［Conclusion/Prospect］ Currently，some bio-based resins still face challenges such as complex preparation processes andrelatively high costs. In the future，by reducing costs and optimizing performance，bio-based resins will play a greater role in the coatings field.
