用N(2胺基乙基)N正辛基1,2乙二胺和N(2胺基乙基)N正癸基1,2乙二胺增塑再生纤维素膜,并用红外光谱、差热分析以及力学性能测量研究了增塑后膜的结构与性能。实验表明,上述二种化合物对纤维素膜有良好的增塑作用。N(2胺基乙基)N正辛基1,2乙二胺水溶性大,和甘油增塑的情况相似,用水浸泡后,增塑效果基本丧失;而N(2胺基乙基)正癸基1,2乙二胺用水浸泡后对纤维素膜仍有比较好的增塑作用,其耐水性明显高于甘油增塑的膜。
N (2 aminoethyl) N octyl 1, 2 ethylenediamine and N (2 aminoethyl) N decyl 1,2 ethylenediamine Plasticized regenerated cellulose film. The structure and properties of the plasticized film were studied by infrared spectroscopy, differential thermal analysis and mechanical properties measurement. Experiments show that the two compounds have good plasticizing effect on the cellulose film. N (2 aminoethyl) N octyl 1, 2 ethylenediamine water-soluble large, and glycerol plasticization similar to water immersion, the basic loss of plasticization effect; and N ( 2 aminoethyl) decyl 1 2 ethylenediamine soaked in water on the cellulose film is still a good plasticizing effect, its water resistance was significantly higher than glycerol plasticized film.
