| 摘 要： | 用超细羊毛粉体改性聚氨酯能得到透湿性较好的膜,但其力学性能下降较大,为了改善聚氨酯膜的防水透湿性和保持膜的力学性能,用超细羊毛粉体和TiO2复合改性聚氨酯的方法制成了聚氨酯干法膜。探讨了粉体的加入对干法膜力学、透湿、吸湿、防水等性能的影响。结果表明,羊毛超细粉体与微米TiO2共混是一种改善聚氨酯膜透湿性能的有效途径。 |
| 关 键 词： | 羊毛粉体 聚氨酯膜 防水透湿 |

| Abstract: | The superfine wool powder modification of polyurethane(PU) can improve the moisture permeability of its membrane,but the mechanical properties of the membrane drops considerably.In order to enhance the waterproof and moisture permeability of PU membrane while retaining its mechanical properties,PU membranes were made through the superfine wool powder and the TiO_2 compound modification of PU.The effect of addition of the powders on mechanical,moisture permeable,hydroscopic and waterproof properties of the membrane was discussed.The results indicate that the superfine wool powder and the TiO_2 compound modification of PU is an effective approach to improve the moisture permeability of polyurethane membrane. |
