AI Technical Summary
Existing magnesium hydroxide flame retardants exhibit poor dispersibility when added to polymer materials, affecting the mechanical properties of composite materials. Furthermore, traditional preparation methods are cumbersome and costly, hindering large-scale production.
A one-step gas-liquid heterogeneous reaction was adopted to prepare a highly oriented magnesium hydroxide flame retardant by controlling the bubbling frequency and volume of ammonia molecules, avoiding the use of directing agents and viscosity reducers, and controlling the process conditions for precipitation reaction and subsequent treatment.
The controlled growth of magnesium hydroxide crystals has been achieved, resulting in products with high purity and uniform particle size. This simplifies the preparation process, reduces production costs, and facilitates industrial production.
