摘要
文中采用含磷阻燃剂二乙基次膦酸铝改性水性聚氨酯,并通过涂层技术提升涤纶织物的阻燃及防熔滴性.主要探究阻燃剂用量与涂层添加量对织物阻燃效果的影响,并研究阻燃涂层织物的燃烧行为、阻燃性、力学性能及耐水压和光泽度.结果表明,当二乙基次膦酸铝用量为2％、涂层为100 g/m2时,织物损毁长度降至12.9 cm,极限氧指数提至28.6％,无熔滴,达B1级阻燃标准,可以有效提高聚氨酯涂层涤纶织物的阻燃性能和防熔滴性能;锥形量热测试表明,最大热释放速率和总烟雾量分别降低24.9％和69.3％,同时,阻燃涂层织物保持良好的力学性能,耐静水压值为52.3 kPa.
Abstract
In this paper,waterborne polyurethane was modified by phosphate-containing flame retardant alu-minum diethylphosphonate,and the flame retardancy and drip resistance of polyester fabric were improved by coat-ing technology.The effects of the amount of flame retardants and the coating weight on the flame retardancy of the fabric were studied,and the burning behavior,flame retardancy,mechanical properties,water resistance and gloss of the flame retardancy coated fabric were studied.The results show that when the dosage of aluminum diethyl phosphinate is 2％and the coating is 100 g/m2,the damage length of the fabric is reduced to 12.9 cm,the limit oxygen index is increased to 28.6％,and there is no melting drop,reaching the Bl flame retardant standard,which can effectively improve the flame retardant and melting drop resistance of polyurethane coated polyester fabric.Cone calorimetric test shows that the maximum heat release rate and total smoke volume are reduced by 24.9％and 69.3％,respectively.Meanwhile,the flame retardant coated fabric maintained good mechanical properties and the hydrostatic pressure is 52.3 kPa.
