　　水滑石是一種層柱狀雙金屬氫氧化物，是一類近年來發展迅速的陰離子型粘土。水滑石具有特殊的結構和物理化學性質，如堿性、帶電性質、陰離子可交換性、微孔結構、熱穩定性、記憶效用、吸附性能、催化性能等,在塑料、橡膠高分子材料的阻燃劑、熱穩劑、催化劑、催化劑載體、殺蟲劑、污水處理劑、電流變調節劑、醫藥、醫藥載體及石油工業等眾多領域具有廣泛的應用。</div> <div> 　　鎂鋁水滑石是一種新型多效塑料添加劑，兼有氫氧化鎂和氫氧化鋁類似的結構和組成，受熱分解時可以吸收熱量，能降低燃燒體系的溫度;稀釋可燃性氣體，同時隔絕氧氣，起到阻燃效果，是一種很有發展前景的無毒、低煙的無鹵阻燃劑新品種，因而具有開發潛力。主要元素是鎂、鋁兩種。氫氧化鎂是合成水滑石的基本原料，水滑石在合成中所需的大量鎂元素都是由氫氧化鎂提供的。主要的合成方法有共沉淀法、水熱法、焙燒復原法、模板合成法、成核/結晶隔離法等。</div> <div> 　　水滑石作為阻燃劑，它兼具氫氧化鋁和氫氧化鎂阻燃劑的優點，又克服了它們各自的不足，目前電工行業主要使用的阻燃材料是顆粒狀氫氧化鎂和氫氧化鋁。在材料溫度上升，降低材料表面放熱量，提高材料自然溫度，延長引燃時間方面，氫氧化鋁的作用效果優于氫氧化鎂，而提高材料自燃溫度，提高氧指數，促進碳化效果方面，氫氧化鎂則優于氫氧化鋁。實驗表明，添加到聚合物中的水滑石受熱分解時，放出的惰性氣體二氧化碳和水蒸氣能稀釋可燃氣體濃度，減弱火勢，而分解得到氧化鎂,氧化鋁可形成隔熱層，同時受熱分解時又吸收了熱量，降低了聚合物的表面溫度，由此可見，水滑石確實具有阻燃,消煙，填充，三種功能，是無機阻燃劑的新品種。同時加入高純消煙劑，有效的降低了材料燃燒時的發煙量。</div>
