| titleOfInvention | Preparation method of alkylphenol modified phenolic resin for electronic material |
| abstract | The invention relates to a preparation method of alkylphenol modified phenolic resin for electronic materials, which can produce high-quality alkylphenol modified phenolic resin by adopting a step-by-step control technology of pressure in a kettle and selecting an organic catalyst in the process of preparing alkylphenol modified phenolic resin for electronic materials. When the alkylphenol modified phenolic resin is prepared, the reaction pressure step-by-step control technology in the kettle is adopted, and the organic catalyst is selected to replace sulfuric acid, hydrochloric acid and the like, so that the reaction activity of alkylphenol can be improved, the full reaction is ensured, the introduction of harmful ions is avoided, the concentration of the harmful ions in the obtained resin can be controlled to be below 1ppm, and the requirements of electronic materials are met. Meanwhile, the alkylphenol modified phenolic resin prepared by the invention does not need to be washed by a large amount of water, which has positive significance for cost control and environmental protection. |
