Embodiment 1

[0090] Synthesis of compound 2:

[0091]

[0092] Dissolve 34.8g (0.1mol) of hexachlorocyclotriphosphazene in 175mL of chlorobenzene solvent, heat to 30°C, and then add 27.3g (0.65mol) of sodium fluoride for fluorination to obtain hexafluorocyclotriphosphazene . Slowly add phenol tetrahydrofuran solution (equivalent to phenol 29.3 g, 0.31 mol) into the hexafluorocyclotriphosphazene solution at 25°C, and use sodium hydroxide as an acid-binding agent to react for 30 minutes. Filter to remove the inorganic salts and unreacted bases generated by the reaction. The filtrate is evaporated under reduced pressure to remove the solvent (recovery and reuse), then add 175 mL of cyclohexane to dissolve, then wash with dilute lye, dilute hydrochloric acid, and 3 times of water to remove impurities. The solvent was removed from the organic layer under reduced pressure (cyclohexane was recovered and reused) to obtain 37.8 g of compound 2 with a yield of 80% and a purity of 99.0%. Boiling...

Abstract

The invention belongs to the technical filed of polymers, and concretely relates to an application of a cyclophosphazene compound represented by formula I in the preparation of resin as an antidrip agent. The invention also provides a resin having an antidrip performance.

Description

technical field [0001] The invention belongs to the technical field of polymers, and in particular relates to the application of cyclic phosphazene compounds as anti-dripping agents in the preparation of resins. Background technique [0002] General-purpose plastics, especially thermoplastic resins, are widely used in electrical devices, office equipment and other fields due to their relatively comprehensive and balanced properties - excellent mechanical strength, impact resistance, heat resistance, good molding performance and appearance, etc. . Although these resins have certain self-extinguishing properties, in order to meet the higher UL94V-0 flame retardant requirements in these fields, it is usually necessary to add flame retardants, such as a large amount of brominated bisphenol A oligomers, decabromodiphenyl ether etc., to increase the limiting oxygen index (LOI) of polymer systems, allowing articles made from these polymer systems to pass standard flame retardancy ...
