In the present study,the modified magnesium hydroxide was prepared by precipitation method using Mg(NO3), NaOH, and silane coupling 702 modifier as raw materials. The optimal reaction conditions were obtained as follows: sodium hydroxide was added to magnesium nitrate solution by dropping, the dropping speed of sodium hydroxide was 2ml/min, the reaction temperature was 60℃, and the ratio of modifier dosage to total solution volume was 7/100(g/ml). The oil absorption value and XRD were used to characterize the modified Mg(OH)2. In the application, the modified magnesium hydroxide was mixed with pentaerythritol octahydrogen tetraphosphate(PEPA) and applied to nylon 66(PA66).The flame retardancy and mechanical properties of the nylon 66(PA66)composite were studied.
