The development process,protective application,reaction mechanism,formulation process and other aspects of polyurea waterproofing material were systematically reviewed,and its main performance,application fields and waterproof effect were discussed.This paper summarizes the existing problems in the research of polyurea waterproofing materials and looks forward to its development prospects,which can provide a reference for the research of polyurea waterproofing materials and the design of new waterproofing materials.It has been revealed that there are various systems and research methods for polyurea elastomer materials,and a complete research system is urgently needed.In terms of microstructure,corresponding improvements can be made for different usage environments and construction conditions.The performance and usage limitations of spraying equipment need to be improved,and the factors affecting polyurea waterproofing and anti-corrosion are analyzed to provide guidance for the research and design of new waterproofing and anti-corrosion materials.
