| titleOfInvention | Lignin and boronic acid modified phenolic resin and method for preparing same |
| abstract | The invention provides a method for preparing lignin and boronic acid modified phenolic resin, comprising the following steps of: (1) mixing phenol, a catalyst and boric acid, and enabling the materials to react for 2-4 hours; (2) adding lignin to the reaction mixture obtained in the step (1), and enabling the lignin and the reaction mixture to react at 105-115 DEG C for 1.5-2.5 hours; and (3) adding aldehyde into the reaction mixture obtained in the step (2), and enabling the aldehyde and the reaction mixture to be subjected to condensation reaction at 100-110 DEG C for 2-3 hours. According to the method, due to the double modification by the lignin and the boronic acid, the defect caused by single modification is overcome. The lignin is introduced into the resin, thus the brittleness of phenolic resin is effectively improved, and the degradation period of the phenolic resin is shortened. In addition, due to the introduction of the boron element, rub resistance, cutting resistance, high-temperature ablation resistance and water resistance of the lignin modified resin are improved greatly. The yield of the resin is improved by 10-45%, and the cost of the resin is reduced greatly. |
