水性聚氨酯膨胀型阻燃涂料的研究进展

水性聚氨酯涂料若未经阻燃处理,存在引发火灾的隐患,因此水性聚氨酯的阻燃研究是水性聚氨酯功能化的重要方向之一。介绍了水性聚氨酯阻燃涂料的分类,按不同分类标准可分为共混复配型和反应型,膨胀型和非膨胀型。对水性聚氨酯阻燃涂料阻燃效应和阻燃机理进行了探讨,并重点介绍水性聚氨酯膨胀型阻燃涂料的研究现状。最后提出了现在水性聚氨酯膨胀型阻燃涂料存在的问题,并对水性聚氨酯膨胀型阻燃涂料的发展趋势进行了展望。

The Research Status and Latest Progress of Waterborne Polyurethane Intumescent Flame Retardant Coatings

Waterborne polyurethane coatings without the flame retardant treatment are flammable, so the research about the flame retardant waterborne polyurethane is an important research direction. The classification of waterborne polyurethane flame retardant coatings was introduced. Flame retardant coatings can be categorized as blending and reactive compound, intumescent and non-intumescent according to different classification criteria. Flame retardant effect and flame retardant mechanisms of waterborne polyurethane flame retardant coatings were discussed and the research of intumescent flame retardant polyurethane coatings was highlighted. Finally, the problems which waterborne intumescent flame retardant polyurethane coating existed and the trends of waterborne intumeseent flame retardant polyurethane coatings development are were proposed.
