| titleOfInvention | Continuous production method of thermosetting phenolic resin |
| abstract | The invention provides a continuous production method of thermosetting phenolic resin, which is carried out in a continuous production device, wherein phenol, a formaldehyde aqueous solution and an alkaline catalyst aqueous solution are conveyed to a mixing unit through a continuous conveying system according to the molar ratio of phenol to formaldehyde to an alkaline catalyst of 1: 1.1-2.5: 0.05-0.5, are uniformly mixed, enter the reaction unit and react for 1-10 min at the temperature of 60-140 ℃, and the thermosetting phenolic resin with the solid content of 65-85% is obtained after dehydration. |
