Abstract:

Nano magnesium hydroxide has a wide application prospect in the flame retardant of polymer materials such as plastics and rubber due to its advantages of green and high efficiency. With the deepening of research, preparation methods such as precipitation method, hydrothermal/solvothermal method and microwave-assisted method have dominated the preparation of nano magnesium hydroxide. In this paper, these three mainstream preparation methods were introduced from the aspects of morphology and particle size control of nano magnesium hydroxide. The mechanism of action in some preparation processes was explored. The advantages and disadvantages of each preparation method were described, and then the preparation methods were compared and summarized. Secondly, the problems and solutions of nano magnesium hydroxide in the application field were discussed, and its application in the field of flame retardant of various polymer materials was summarized. The flame retardant mechanism of nano magnesium hydroxide was explored from many angles by combining theory with examples. Finally, the opportunities and challenges encountered in the preparation methods and applications of nano magnesium hydroxide were prospected, hoping to provide useful inspiration and reference for further research on nano magnesium hydroxide.
