- 摘要:
- 热塑性聚氨酯（TPU）颗粒通过除杂除油处理后,用六亚甲基二异氰酸酯（HDI）对其进行活化处理,使其两端形成自由的异氰酸酯基团（—NCO）.再加入MCDEA（4,4’亚甲基双（3氯2,6二乙基苯胺)）,使MCDEA中的—NH2和TPU两端自由—NCO进行反应,生成脲基（—NHCONH）,从而使MCDEA进入TPU体系.通过加入不同量的MCDEA,以及MOCA（3,3’二氯4,4’二氨基二苯甲烷）和DMTDA（3,5二甲硫基2,4甲苯二胺及3,5二甲硫基2,6甲苯二胺两种异构体的混合物）分别对TPU进行嵌段改性,并对改性后的TPU胶膜进行拉伸性能测试.结果表明,在TPU和MCDEA比例为1/7时拉伸性能最好,同时选择拉伸性能较好且几乎无毒的MCDEA较为适宜.
- Abstract:
- TPU was activated by hexamethylene diisocyanate (HDI) after the treatment of oil removing and cleaning the surface, and form free isocyanate groups(—NCO) on both sides. Then the ureido(—NHCONH) was formed by the reaction of amino groups (—NH2) of MCDEA and the free —NCO groups above. In the research, the tensile properties of TPUs modified by MCDEA MOCA and DMTDA respectively, were examined. The result show that nontoxic MCDEA was satisfactory to modify TPU, the best propertie was realized under the blend of TPU and MCDEA with ratio of 17.
