| titleOfInvention | High-molecular phosphorus-silicon-containing flame retardant and preparation method thereof |
| abstract | The invention relates to the technical field of organic flame retardants, in particular to a high-molecular phosphorus-silicon-containing flame retardant and a preparation method thereof, wherein the preparation method comprises the following steps: (S1) heating the flame retardant intermediate DOPO to a molten state, then adding phenyl vinyl silicone oil into the molten flame retardant intermediate DOPO for mixing, and heating to initiate reaction for 10-15h to obtain the DOPO-grafted phenyl vinyl silicone oil; (S2) uniformly mixing the aromatic vinyl monomer and the phenyl vinyl silicone oil grafted with DOPO, then adding water and a separant, uniformly mixing, then adding an initiator A, raising the temperature to 70-85 ℃ under the condition of continuous stirring, initiating reaction for 6-8h, then filtering, washing and drying to obtain the high-molecular phosphorus-silicon-containing flame retardant. The preparation method has the advantages of simple operation, convenient control, high production efficiency and low production cost, and can be used for large-scale production. |
