摘　　要：　文章首先论述了聚合物的着火燃烧过程与无机阻燃剂氢氧化镁的阻燃消烟机理,接着论述了氢氧化镁阻燃剂所需的特殊结构及相应的制备技术,经过水热反应可把普通氢氧化镁改性成为具有片状结构的阻燃级氢氧化镁。In this paper,the combustion mode of polymers is introduced,the fire resistant & smoke abatement mechanisms of Mg(OH)_2 as inorganic flame retardent are given, and the special structure and production method of Mg(OH)_2 as flame retardent are discussed. The Mg(OH)_2 with special structure can be obtained with the hydrothermal modification reaction after the ordinary Mg(OH)_2 is firstly synthesized at normal temperature.
