Pressure-sensitive adhesive (PSA) is a kind of viscoelastic material with the viscous properties of liquids and the elastic properties of solids that can adhere to the surfaces of various substrates only under light pressure without phase change. PSAs derived from petroleum-based materials are generally non-biodegradable and disposable; therefore, a large amount of waste is generated from PSA products. Preparation of PSAs using renewable vegetable oil as raw material is an effective way to reduce dependence on petrochemical resources and environmental pollution. This paper summarizes the recent progress on vegetable-oil-based PSAs. Vegetable-oil-based PSAs mainly include epoxy resin, acrylic resin, fatty acid derivatives, polyester and polyurethane according to the chemical structures of vegetable-oil-based polymers. The design ideas and modification methods of vegetable-oil-based PSAs are introduced, including the development of functional vegetable oil monomers and the optimization of the polymer structure, so as to provide theory and reference for the design and development of new bio-based PSAs.

植物油基压敏胶的研究进展

压敏胶（PSA）是一种兼有液体的粘性和固体的弹性特性，只需在轻压力下即可粘附于各种基材表面而不发生相变的粘弹性材料。源自石油基材料的压敏粘合剂通常不可生物降解且是一次性的；因此，PSA 产品会产生大量废物。以可再生植物油为原料制备PSA是减少对石化资源依赖和环境污染的有效途径。本文总结了植物油基压敏粘合剂的最新进展。植物油基压敏胶根据植物油基聚合物的化学结构主要包括环氧树脂、丙烯酸树脂、脂肪酸衍生物、聚酯和聚氨酯等。介绍植物油基压敏胶的设计思路和改性方法，包括功能性植物油单体的开发和聚合物结构的优化，为新型生物基压敏胶的设计和开发提供理论和参考。 。
