| titleOfInvention | method for preparing composite coating by induced mineralization of waterborne polyurethane coating |
| abstract | the invention discloses a method for preparing a composite coating by inducing and mineralizing an aqueous polyurethane coating, which comprises the steps of preparing a compound neutralizer by using a metal hydroxide and organic amine, neutralizing, salifying and emulsifying a polyurethane prepolymer to obtain an aqueous polyurethane emulsion, placing the emulsion in seawater after film forming and curing, and inducing and mineralizing the surface of the coating to obtain an inorganic coating. The preparation process is simple, the production and use processes are green and pollution-free, the surface hardness of the coating is improved from 2H to 5H after induced mineralization, and the seawater corrosion resistance is improved by about 10 times compared with that before mineralization. |
