中文摘要:

      氢氧化镁是一种重要的无卤阻燃剂，为了改善其阻燃效率低、与高分子材料相容性差等缺点，通常需要使用阻燃添加剂对其进行特殊处理，使之具备更好的阻燃性能。主要介绍了氢氧化镁作为阻燃剂的特性及其阻燃机理；硅烷偶联剂的结构特点及改性氢氧化镁的方法和机理；影响改性的因素以及改性效果的测评方法，并对硅烷偶联剂改性氢氧化镁的研究进展进行了概述。

英文摘要:

      Magnesium Hydroxide is an important non-halogenated flame retardants. In order to improve the low fire retardancy efficacy and poor compatibility with substrate, endeavors will be focused on developing a magnesium hydroxide package using flame retardant additives. This paper mainly introduce the advanta- ges and disadvantages of magnesium hydroxide and its flame retardant mechanism, the methods and mechanism of the surface modification of magnesium hydroxide with silane coupling agent, the influence of factors and the evaluation methods of modification effect, and the application of magnesium hydroxide were also introduced.
