| Abstract: |
| 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. |
