| Zusammenfassung: | The invention discloses a method for recycling and treating pnenolic aldehyde sewage water. The method is that first preparing widely distributed preliminary formaldehyde-phenol resin, then after catalysis, polymeric fixing temperature, reaction fixing speed and monohydric fixing position, obtaining senior formaldehyde-phenol resin. The Mw molecular weight of the obtained formaldehyde-phenol resin is stabilized between 3500-3700, the interlinkage is clear and the distributing structure of the molecular is reasonable, which can be used in the special fields of fire resistive material, polishing resistive material, forming material and the like. |
