摘要
聚天冬氨酸酯(PAE)聚脲是一种新型脂肪族、慢反应、高性能环保树脂,具有凝胶时间长、附着力好、固含量高、耐紫外线辐射好等特点。综述了PAE聚脲的研究进展,介绍了PAE聚脲组成、改性以及PAE聚脲在国内应用实例,并展望了聚脲技术的发展趋势与方向。
Polyurea based on polyaspartic esters（PAE） is a new type of aliphatic, slow reaction, high performance environmentally-friendly resin, it has numerous excellent characteristics such as long gel time, good adhesion, high solid content, UV resistance and so on. The present research progress of PAE is reviewed, the constitution, modifications and the applications of PAE are introduced, and the development of PAE is expected.
