| Abstract: |
| As the environmental awareness increases continuously, environmentally friendly functional waterborne polyurethane architectural coatings are favored. The application status and the latest research progress of functional waterborne polyurethane coatings in the construction industry in recent years have been summarized. Water-borne polyurethane coatings are widely used in the construction industry due to environmental protection of water-based paint and high performance of polyurethane coating, and mainly include waterproof coating, anti-corrosion coatings, anti-mildew coatings, abrasion resistant coatings and fire retardant coatings. Due to the introduction of hydrophilic groups into the water-borne polyurethane molecules, water resistance, stain-resistance, anti-corrosion, antifungal and antifungal properties, abrasion and impact resistance deteriorates and the application range is limited in some certain. To solve this problem, nano-modification, compound modification, cross-linking modification and blend modification on waterborne polyurethane coatings were conducted by researchers. The main research direction of future waterborne polyurethane coating is put forward by summarizing the research progress of domestic and foreign scholars for waterborne polyurethane coatings in recent years and combining the development level of domestic waterborne polyurethane, which aims to develop high performance and high quality products by the method of surface modification so as to meet high performance, function, nature, environmental safety and decoration requirements of waterborne polyurethane coating in architectural and environment design. |
