摘要:

采用协效复合型阻燃剂FR-PN-G对黄麻/聚丙烯复合毡进行阻燃整理,利用正交试验方法优化阻燃剂质量浓度、浸渍时间、浸轧次数等阻燃工艺参数,得出最佳阻燃工艺参数:阻燃剂质量浓度为450 g/L,浸渍时间为20 min,浸轧次数为2次。在此工艺参数下进行阻燃整理,测得黄麻/聚丙烯复合纤维毡的极限氧指数为35.2%,炭长40 mm,续燃时间0 min,阴燃时间0 min,拉伸强度24.95 MPa,弯曲强度30.27 MPa,表明阻燃综合效果最佳。

Abstract: Using FR-PN-G,a synergistic flame retardant,to treat the jute/polypropylene fiber needle felt,and optimized the concentration of flame retardant,dipping time,dip pressing times by using orthogonal test.The optimum processing parameters were determined: concentration of flame retardant is(450 g/L,) dipping time is(20 min,) dip pressing times is 2.The flame retardant finishing of the jute/polypropylene fiber needle felt was performed by using these processing parameters,and as showed in the following test results that the best overall flame retardant effect has been achieved: its LOI is 35.2%,char length is(40 mm,)after flame time is(0 min),afterglow time is(0 min,)tensile strength is (24.95 MPa,) and bending strength is(30.27 MPa.)
