Abstract

The objective of this study was to develop a highly durable synthetic leather with excellent resistance to light discoloration and deterioration without the use of fluorine or silicon and a surface that is resistant to dyes and odors. Environment-friendly biomass feedstock was used as the reaction component. Firstly, polyurethane (PU) resins with varying glass transition temperatures ( Tg) were synthesized. Subsequently, these were used as surface treatment agents for synthetic leather, and the relationship between the non-staining performance of the PU resin and the Tg values was discussed. In addition, the physical durability over time was investigated. The non-staining performance of the synthetic leather surface against dyed clothing and the odor of ammonia evidently depended on the Tg of the PU resin used as the surface treatment agent. The Tg range that is the most convenient for practical purposes, and the related best light discoloration and degradation resistance and bending resistance, were confirmed, and serve as indicators that the material can be used as a highly durable interior material.

由不同玻璃化转变温度的聚氨酯树脂组成的合成皮革对染料和气味的无沾污性

这项研究的目的是在不使用氟或硅的情况下，开发一种耐久性极强的合成皮革，这种皮革具有出色的耐光变色和耐劣化性能，而且表面耐染料和气味。反应组分采用环保型生物质原料。首先，合成了不同玻璃化转变温度（Tg）的聚氨酯（PU）树脂。随后，这些聚氨酯树脂被用作合成皮革的表面处理剂，并讨论了聚氨酯树脂的不沾污性能与 Tg 值之间的关系。此外，还对物理耐久性进行了研究。合成皮革表面对染色衣物和氨气味的不沾污性能显然取决于用作表面处理剂的聚氨酯树脂的 Tg 值。确认了最适合实用目的的 Tg 值范围，以及相关的最佳耐光变色和降解性以及耐弯曲性，并以此作为该材料可用作高耐久性内饰材料的指标。
