Mechanism and Preparation Methods of Inorganic Fire-Retardant

The flame-retardant mechanisms of aluminium hydroxide (ATH) and magnesium hydroxide (MH) that used as typical inorganic fire-retardant were illustrated. The preparation methods of the fire-retardants are reviewed. And the modification approaches and future development direction of the fire-retardants were also discussed. Although the ATH and MH are environmental friendly flame retardants, they still have drawbacks and further research is needed to improve their flame retardant properties.
