Preparation of Nano - SiO₂ Modified Waterborne Polyurethane Coatings and Its Influence on the Anti - Permeability of Concrete

For improving the anti-permeability of waterborne polyurethane coatings to concrete,the silane coupling agent was applied to modify the surface of nano-SiO2 to reduce the reunion degree of nanoparticles,and then the modified nano-SiO2 with better dispersibility was added into the water...
