有机硼系阻燃剂的研究与开发

硼资源丰富,有开发前景.早在18世纪已经用硼砂作为阻燃剂(是最早期的无机硼系阻燃剂).有机硼阻燃剂始于1942年,但因不稳定(易水解)而限制了它的应用.近代有机硼系阻燃剂的研究与开发是利用硼原子的电子层结构缺电子性,有接受电子的能力,可以与氮原子等富电子元素形成配位键,开发了硼-氮、硼-磷、硼-卤与硼-硅分子内复合型有机硼系阻燃剂,具有良好的阻燃、抑烟性能且无毒.介绍了硼系阻燃剂的若干品种,并就硼与其他元素协同阻燃机理进行了探讨.

Study and development on organic boron-containing flame retardants

Boron is abundant in resources and has development prospect.Borax has been used as flame re-tardant in the early 18th century,which is the earliest inorganic boron flame retardant.Organic boron flame re-tardant was invented in 1942,but its application was limited due to the instability(easy to hydrolyze).The investi-gation and development of organic boron-containing flame retardants in recent times utilized the electron-defi-cient nature of boron atoms electron shell structure,which had the ability to recei...
