Description

technical field [0001] The invention relates to the field of coatings, in particular to a stain-resistant and waterproof coating of organic fluorine-modified polyurethane. Background technique [0002] Waterborne polyurethanes are an important class of coating resins with properties tunability, excellent abrasion resistance, adhesion and durability. As an important member of water-based products, waterborne polyurethane is facing unprecedented development opportunities due to its unique and excellent performance. But in fact, some properties of waterborne polyurethane are not satisfactory, such as hardness, water resistance, tensile strength and so on. Therefore, in order to improve the comprehensive performance of waterborne polyurethane coatings, waterborne polyurethane modification has become an inevitable trend. Fluorine monomers or fluoropolymers play an important role in improving the hydrophobicity, water absorption, chemical resistance, weather resistance, nuclear ...
