| 中文摘要: |
| 首先介绍了聚脲弹性体的合成原料和合成机理，然后根据合成原料的不同，对聚脲弹性体进行了分类，简述了不同种类聚脲弹性体的特点。在此基础上，总结了聚脲弹性在温度、紫外光、腐蚀介质等单因素条件作用下的退变行为和在氯盐浸渍、干湿循环、荷载作用和冻融循环等多因素耦合作用条件下的退化行为。综述了提升聚脲弹性体防腐性能、力学性能和附着力的改性研究进展，最后指出了当前聚脲弹性体退化行为研究中存在的不足，并展望了未来的研究趋势。 |
| 英文摘要: |
| This article first introduced the synthetic materials and principles of polyurea elastomers, classified them by their different synthetic materials, and described characteristics of different kinds of polyurea elastomers. On this basis, it further con-cluded two types of degradation behaviors. The former resulted from single-factor conditions of the temperature, ultraviolet ray, and aggressive medium; while the later was caused by multi-factor coupling effects of chlorine salt immersion, dry-wet cycle, load effect, and freeze-thaw cycles. Furthermore, this article summarized the progress of studies on improving antiseptic properties and mechanical properties, and modifying adhesive force of polyurea elastomers. In the end, deficiencies and outlook of research trends of studies on polyurea elastomer degradation behaviors were pointed out. |
