摘　　要：以硅烷偶联剂氨丙基三乙氧基硅烷(KH550)为改性剂,将改性处理后的棉纤维(CF)与氢氧化铝(ATH)和环氧树脂(EP)共混,制备得到棉纤维/氢氧化铝/环氧树脂(CF/ATH/EP)复合材料。通过测试复合材料的力学性能、剪切强度、极限氧指数(LOI)、热释放速率、抗紫外性能及拉伸断裂面微观形貌,分析了CF/ATH的用量比对复合材料综合性能的影响。结果表明:当CF/ATH的用量比为20/30时,复合材料具有较为优异的性能,LOI达到30.6%,垂直燃烧等级为V-0级,热释放速率为234.35 kW/m^2,剪切强度最佳为19.4 MPa,复合材料具有优良的抗紫外性能,可以制备得到综合性能较佳的高模量阻燃抗紫外纺织服装材料。Using KH550 as modifier,CF/ATH/EP composites were prepared by blending modified cotton fiber(CF)with aluminum hydroxide(ATH)and epoxy resin(EP).The mechanical properties,shear strength,limiting oxygen index,heat release rate,UV resistance and tensile fracture surface morphology of the composites were tested,and the influence of CF/ATH content on the comprehensive properties of the composites were analyzed.The results showed that when the ratio of CF/ATH is 20/30,the composites have excellent properties,the LOI is 30.6%,the vertical combustion grade is V-0,the heat release rate is 234.35 kW/m^2,the shear strength is 19.4 MPa.The composites have excellent UV resistance,which can be used to prepare high modulus flame retardant and UV resistant textile clothing materials with better comprehensive properties.
