Description

technical field [0001] The invention relates to the technical field of waterborne polyurethane coatings, in particular to an antibacterial and environmentally friendly polyurethane coating and a preparation method thereof. Background technique [0002] Water-based polyurethane uses water as the dispersion medium. Compared with traditional solvent-based polyurethane, it has the advantages of environmental protection, non-flammability, and non-toxicity. It is widely used in coatings, adhesives, leather finishes, and textile industries. However, the water-based polyurethane film has weak anti-ultraviolet aging ability and is easily polluted, which affects its use effect. Studies have shown that nanocomposites modified by inorganic nanoparticles not only have the properties of polymers such as ductility and elasticity, but also exhibit the properties of the added inorganic materials. Nano-titanium dioxide (TiO2) is an important inorganic semiconductor material, which has excell...
