聚氨酯合成革黄变问题的分析探讨

The Discussion on Yellowing Problem of Polyurethane Synthetic Leather

聚氨酯树脂作为合成革的主要原材料具有优异的物理机械性能,但是聚氨酯树脂容易黄变,造成聚氨酯合成革在使用中出现一些问题。为了解决聚氨酯合成革黄变问题,探讨了聚氨酯合成革黄变的机理及检测方法,并就提高聚氨酯合成革的耐黄变性能的方法进行了介绍。

The polyurethane as the material of synthetic leather has a good physical property, but the polyurethane usually gets yellow easily. So it will bring some problems to PU leather. For solving these problems, the yellowing mechanism and the anti-yellowing measures of polyurethane synthetic leather were discussed. And the ways of enhancing the anti-yellowing ability were discussed.
