摘要
介绍了国内外游离甲醛消除剂的研究进展。目前 ,甲醛消除剂主要分为三类 :氧化剂型、氨基衍生物型和含α -氢化合物型 ,文中分析了它们的消醛机理和各类的优缺点及发展方向。其中氨基衍衍生物型甲醛消除剂具有消醛率高、使用量少、水溶性好和无毒等优点 ,是消醛剂的主要品种。含α -氢化合物型是今后研究的新方向 ,新型的消醛剂应同时具有消醛和改性的两种作用。
The research development of free-formaldehyde scavengers over the world was introduced. Free-formaldehyde scavengers were divided three types: oxidizer type, amino-derivative type and α-hydrogen containing compound type. The scavenging formaldehyde mechanism, virtues and defects of these scavengers were analyzed; research orientation was foreseen. Amino-derivative type has high scavenging formaldehyde efficiency, low used amount, good solubility in water and no-toxicity. α-hydrogen containing compound type will be research henceforth. New type of formaldehyde scavengers should have scavenging formaldehyde function and modifying function at the same time.
