The gimini phosphate surfactant was synthesized by using phosphorus oxychloride and ethylene glycol as raw materials.The zinc borate whisker was modified with gemini phosphate by hydrothermal synthesis.The FT-IR,XRD,1H-NMR,SEM and TEM were used to characterize the gemini phosphate and the modified zinc borate whiskers.The Water contact angle and the activation index were used to characterize modification effect.The composite materials were prepared by polyethylene and zinc borate whiskers.The flame retardancy of the materials was investigated.The results showed that the 1% content of the geminitic phosphate had a good modification effect.The zinc borate whisker was changed from hydrophilic to hydrophobic.The water contact angle reached 159.8°.The activation index reached 99.5%.The limit oxygen index of the materials reached 29.4%.
