摘要
目前在合成革领域亟待解决的问题就是合成革在吸湿透气方面与天然革的差距还比较明显。本文对非离子聚氨酯干法面层的吸湿透气行为进行了研究。讨论了非离子共聚组分的引入对聚氨酯合成革吸湿透气行为的影响。结果表明亲水基团PEG的引入可以提高合成革吸湿透气性能。并且微相分离大的吸湿透气性能差。
At present the urgently problem in synthetic leather field is the distinctness difference of moisture absorption ability between synthetic leather and savageness leather. In this paper, the non-ion polyurethane dry coating moisture absorption ability have been studied. And at the same time the influence of the non- ion copolymer composition introduction on polyurethane synthetic leather are also investigated. The result show that the introduction of PEG, a hydrophile component can enhance the moisture absorption ability of synthetic leather. And if the degree of microsphase seperation is enhanced, the leather moisture absorption ability will go down.
