| titleOfInvention | Solid thermosetting phenolic resin and method for preparing same by adopting suspension method |
| abstract | The application discloses a solid thermosetting phenolic resin and a method for preparing the phenolic resin by adopting a suspension method, wherein the method comprises the following steps: step 1, using divalent metal salt as a catalyst, reacting phenol and formaldehyde in water to form a reaction system taking water as a continuous phase and a synthetic product of the phenol and the formaldehyde as a disperse phase; and 2, adding a dispersing agent into the reaction system to enable the synthetic product of the phenol and the formaldehyde to form particles, and continuously reacting and then treating to obtain the solid thermosetting phenolic resin. The application provides a method for preparing solid thermosetting phenolic resin by adopting a suspension method, the heat release in the production process is mild, the reaction process is easy to control, and the prepared solid thermosetting phenolic resin has good heat resistance, electrical property and storage stability. |
