| titleOfInvention | The preparation method of a kind of phenol-formaldehyde resin modified and the phenol-formaldehyde resin modified prepared by the method |
| abstract | Preparation method that the present invention provides a kind of phenol-formaldehyde resin modified and the phenol-formaldehyde resin modified prepared by the method, organic boron and Cardanol is used to carry out dual modified to phenolic resin, step is: first the aldehyde of organoboron compound with excess is reacted generation methylolated organic boron in the basic conditions, add phenol, Cardanol and acidic catalyst, reacting 1 6h under the acid condition that temperature is 90 120 DEG C, dehydration obtains phenol-formaldehyde resin modified.Use the phenol-formaldehyde resin modified for preparing of the inventive method to have good thermostability, toughness, and low cost, also there is good environmental benefit. |
