摘　　要：以再生纤维素纤维为基体,MS-200型钛酸酯偶联剂改性密胺树脂为功能性添加助剂,制备改性密胺树脂-纤维素复合纤维。介绍MS-200型钛酸酯偶联剂改性密胺树脂的制备方法,并对改性密胺树脂-纤维素复合纤维的形态结构、热学性能、阻燃性能以及物理机械性能进行测试分析。结果表明:MS-200型钛酸酯偶联剂改性密胺树脂-纤维素复合纤维的截面形态与普通纤维素纤维类似,改性密胺树脂在纤维横截面中均匀分布;与普通纤维素纤维相比,改性密胺树脂-纤维素复合纤维的热稳定性有所下降,但残碳率增加,极限氧指数升高,干断裂强度和湿断裂强度都有提升,但纤维中改性密胺树脂的流失量较大,干态下断裂伸长率下降。MS-200 titanate coupling agent modified Melamine resin is used as functional additive to prepare modified Melamine resin/cellulose composite fiber. The preparation of Melamine resin modified by MS-200 titanate coupling agent is introduced, the morphology, thermal properties, flame retardancy and physical and mechanical properties of the modified Melamine resin/cellulose composite fiber are tested and analyzed. The results show that the cross-section morphology of MS-200 titanate coupling agent modified Melamine resin/cellulose composite fiber is similar to that of common cellulose fiber, and the modified melamine resin distributed evenly in the cross-section of fiber. Compared with ordinary cellulose fiber, the thermal stability of modified Melamine resin/cellulose composite fiber decreases, but the carbon residue rate increases, the limiting oxygen index increases, the dry fracture strength and wet fracture strength also increases, however, the loss of modified melamine resin in the fiber is large, and the breaking elongation decreases in dry state.
