氢氧化镁具有阻燃、抑烟、填充的三大功能，是一种新型的绿色环保无机阻燃剂，具有广泛的用途。介绍了氢氧化镁阻燃剂的特点、阻燃机理，重点阐述了氢氧化镁表面改性技术的现状，展望了氢氧化镁阻燃剂表面改性的研究方向。%As new green and environment-friendly inorganic flame retardant, magnesium hydroxide has three functions including inflaming retarding, smoke abatement and filling, so it has been widely applied. In this paper, property characteristics and flame retardant mechanism of magnesium hydroxide flame retardant were introduced.The surface chemical modification methods of magnesium hydroxide were mainly expounded. And the development direction of the surface modification of magnesium hydroxide flame retardant was prospected.
