| titleOfInvention | Corrosion-resistant sprayed polyurea and preparation method thereof |
| abstract | The invention provides a corrosion-resistant spray polyurea. The invention firstly modifies isocyanate by hydroxyl-terminated fluorine-containing silicone oil to obtain a modified isocyanate prepolymer, so as to improve the acid and alkali corrosion resistance of the isocyanate prepolymer; In the preparation process of the polymer, considering that the activity of the catalyst should not be too strong, so as to avoid the reaction in the reaction process running out of control, and proceeding toward the trimerization reaction, the present invention adopts a self-prepared catalyst, adopts the method of catalysis and inhibition of catalysis, and first allows it to form. The salt makes the reaction controllable and facilitates the reaction. In addition, the raw polyester polyol in the A component used in the present invention reacts with alicyclic isocyanate and aromatic isocyanate to further improve the corrosion resistance of the isocyanate prepolymer, and at the same time improve the mechanical strength of the final polyurea; The raw materials of component B and component A are reacted by appropriate ratio, and the obtained polyurea has moderate viscosity, can achieve good spraying, short surface drying time, and outstanding resistance to strong acid and alkali. |
