摘　　要：为了解决阻燃水性聚氨酯在含浸应用中耐碱性差的问题,通过引入阻燃硅油改善阻燃水性聚氨酯的耐碱性,合成了一系列具备耐碱性的阻燃水性聚氨酯,结合湿法含浸的方式将其制备成阻燃超纤贝斯,然后对其耐碱、阻燃、力学及品质性能等进行了相关分析测试,协同阻燃后整理工艺,通过含浸磷氮型的阻燃剂确定了一款综合性能较佳的阻燃超纤贝斯的工艺配方。结果表明,阻燃硅油的引入可以有效改善阻燃水性聚氨酯及阻燃超纤贝斯的耐碱性。随着阻燃含磷二醇的加入,超纤贝斯的水平燃烧速率从121.37 mm/min降低至61.15 mm/min,较未阻燃降低了49.62%,LOI从18.8%提高至23.8%,较未阻燃提高了26.60%。通过含浸磷氮型阻燃剂进行阻燃后整理,LOI最高可达33.4%。为耐碱性阻燃超纤贝斯的制备提供了新思路。In order to solve the problem of poor alkali resistance of flame retardant waterborne polyurethane in impregnation applications,the alkali resistance of flame retardant waterborne polyurethane was improved by introducing flame retardant silicone oil,a series of flame retardant waterborne polyurethanes with alkali resistance were synthesized,and it was prepared into flame retardant microfiber bass by wet immersion,and then its alkali resistance,flame retardant,mechanics and quality properties were tested,and the process formula of flame retardant microfiber bass with better comprehensive performance was determined by the flame retardant impregnated phosphorus and nitrogen type flame retardant in the finishing process.The results show that the introduction of flame retardant silicone oil can effectively improve the alkali resistance of flame retardant waterborne polyurethane and flame retardant microfiber bass.With the addition of flame-retardant phosphoryl-containing glycol,the horizontal combustion rate of microfiber bass decreases from 121.37 mm/min to 61.15 mm/min,which is 49.62%lower than that before flame retardant,and the LOI increases from 18.8%to 23.8%,which is increased by 26.60%compared with that before flame retardant.Through flame retardant finishing with phosphorus and nitrogen impregnated flame retardants,LOI can be up to 33.4%.It provides a new idea for the preparation of alkaline-resistant flame-retardant microfiber bass.
