| titleOfInvention | Phosphorus-nitrogen-bromine flame retardant and preparation method thereof |
| abstract | The present invention relates to a phosphorus-nitrogen-bromine flame retardant, and its structural formula is shown in formula I. The preparation method of the phosphorus-nitrogen-bromine flame retardant includes the following steps: 1) tribromophenol, tribromophenol Phosphorus oxychloride mixed, slowly heated, stirred, and then dropwise added the benzene solution of pyridine, controlled the titration speed, kept warm for reaction, then slowly raised the temperature to react, stopped heating, continued to stir overnight; suction filtered, took the filtrate, raised the temperature, and added Add distilled water dropwise, after the dropwise addition, slowly raise the temperature, keep warm for the reaction, stop heating, and continue stirring overnight; cool, filter with suction, wash with ethanol, wash with water, and dry the filter cake to a constant weight to obtain a white solid. The obtained intermediate bis-(tribromo Phenyl) phosphoric acid diester is mixed with melamine, stirred and dissolved, then slowly heated up, heat preservation reaction, washed with water, suction filtered, washed with ethanol, and the filter cake is dried to constant weight to obtain a phosphorus-nitrogen-bromine flame retardant. The invention has the advantages of moderate thermal decomposition temperature, strong surface migration resistance, high flame retardant efficiency and the like. I |
