| titleOfInvention | Method for producing methylene urea polymer |
| abstract | PROBLEM TO BE SOLVED: To provide a method for producing methylene urea which can be carried out quickly and simply and has a high cost reduction effect. SOLUTION: The production method of the present invention comprises at least urea, A method for producing methylene urea using a formaldehyde compound and an acid, comprising introducing the urea and the formaldehyde compound into a first section of a multi-screw extruder 70, In the section, mixing the urea and the formaldehyde compound, compressing, heating and melting to a fluid mixture, Adding acid to the molten mixture and further mixing in the second section of the multi-screw extruder, the mixture reacting with the acid to form a mass of methylene urea polymer, and extruding the mass. I do. |
