| titleOfInvention | Lignin modified thermoplastic phenolic resin and preparation method thereof |
| abstract | The invention relates to lignin modified thermoplastic phenolic resin which is characterized in that the thermoplastic phenolic resin is prepared by a component A and a component B through polycondensation. The component A is a product obtained through an activating reaction on lignin by using a phenolic compound and rare-earth oxide/an activated carbon catalyst, and the component B is an acid catalyst and an aldehydes compound. A carrier of the rare-earth oxide/the activated carbon catalyst is activated carbon, and active component loaded on the activated carbon is the rare-earth oxide. The invention further relates to a method for preparing the lignin modified thermoplastic phenolic resin. The method is that the rare-earth oxide/the activated carbon catalyst is added to increase absolute quantity of phenolic hydroxyl groups and alcoholic hydroxyl groups of the lignin, increase of phenolic hydroxyl group quantity can substantially improve reactivity of the lignin, and a substitution rate of the lignin on phenol is improved. |
