Foam Finishing and Preparation of Flame Retardant and Heat Insulation Protective Fabric

开发成本低廉的阻燃隔热面料,替代价格昂贵的高性能纤维面料,对于家庭用消防装具的普及和降低消防服装成本有着积极意义。文中在对无机纳米颗粒材料进行表面结构调控和对玻璃纤维进行表面处理的基础上,由泡沫整理实现玻璃纤维织物上黏弹性材料的薄层涂敷,通过对氢氧化铝和玻纤织物的表面处理,在玻纤织物表面应用足量隔热材料时,保证氢氧化铝与有机聚合物材料在玻纤织物表面的耐摩擦牢度和面料的阻燃性能及热防护性能达到要求。结果表明,制备得到的阻燃隔热防护面料,燃烧后碳长2.0mm,阴燃及续燃时间为0,且没有溶滴产生;面料热防护性能为35.80J/cm^(2)·s,达到芳纶的热防护水平;面料功能层的干摩为4级,湿摩为3级。

The development of low-cost flame retardant and thermal insulation fabrics to replace expensive highperformance fiber fabrics is of positive significance for the popularization of household fire-fighting equipment and reducing the cost of fire-fighting clothing.In this paper,on the basis of the regulation of the surface structure of inorganic nanoparticle materials and the surface treatment of glass fiber,the thin layer coating of viscoelastic material on glass fiber fabric is realized by foam finishing,and through the surface treatment of aluminum hydroxide and glass fiber fabric,it ensures that sufficient heat insulation materials are applied on the surface of glass fiber fabric,and the rubbing fastness of aluminum hydroxide and organic polymer on the surface of fiberglass fabric and the flame retardancy and thermal protection of the fabric are improved.As a result,the flame retardant and heat insulating protective fabric is prepared,the carbon length after combustion is 2.0 mm,the smoldering and reburning time is O,and there are no solution droplets.The thermal protection property of the fabric is 35.80 J/cm^(2)·s,which reaches the thermal protection level of aramid.In addition,the dry friction fastness of the functional layer of the fabric is grade 4,and the wet friction fastness is grade 3.
