介绍了氢氧化铝的阻燃机理、氢氧化铝表面改性和协同增效等改性方法,概述了氢氧化铝及其复合体系在塑料、橡胶、纤维等聚合物中的应用现状。分析了国内外氢氧化铝在阻燃剂市场上的占有率。分析结果表明,氢氧化铝在国外阻燃剂市场的占有率为50%~80%,而在我国的占有率却十分有限,故无毒、抑烟、环保的阻燃剂将是未来阻燃剂发展的主流,其中性能良好的氢氧化铝具有广阔的应用前景。 The flame retardant mechanism of aluminum hydroxide, the surface modification of aluminum hydroxide and the synergism of aluminum hydroxide were introduced. The application of aluminum hydroxide and its composite system to polymers such as plastic, rubber and fiber were summarized. The domestic and international market share of aluminum hydroxide in flame retardants was analyzed. The analysis shows that the share of aluminum hydroxide in foreign markets is 50% ~ 80%, while its share in China is very limited. Therefore, non-toxic, smoke-inhibiting and environment-friendly flame retardants will be the future flame retardant The mainstream of agent development, of which good performance of aluminum hydroxide has broad application prospects.
