| titleOfInvention | A kind of melamine water reducing agent and preparation method thereof |
| abstract | The invention relates to a melamine water reducing agent and a preparation method thereof, belonging to the technical field of chemical synthesis. The raw materials used include the following components in parts by weight: 15-25.5 parts of melamine, 38-43 parts of 38% aqueous formaldehyde solution, 10-23 parts of sodium thiosulfate, 1-2 parts of citric acid, 5-8 parts of 40% aqueous potassium carbonate solution parts, 30 to 45 parts of water. The invention shortens the preparation period of the process by changing the feeding sequence. Compared with the existing production process, the preparation method of the present invention shortens the reaction time by more than 4 hours. The present invention avoids the use of strong corrosive chemicals such as concentrated sulfuric acid and sodium hydroxide, ensures the safety of workers and reduces the risk of safety accidents during production. |
