摘要
对比了天然真皮、聚氨酯(PU)超细纤维合成革和聚氯乙烯(PVC)合成革的结构和生产工艺,对材料性能进行了测试、对比及分析.结果表明:在力学方面,PU超细纤维合成革的综合性能更好,优于真皮和PVC合成革;在弯折性能方面,PU超细纤维合成革和PVC合成革性能相近,湿热、高温、气候交变老化后,以及低温状态下弯折性能优于真皮;在耐磨性能方面,PU超细纤维合成革和PVC合成革的抗磨损破洞能力优于真皮;在其他材料性能方面,真皮、PU超细纤维合成革和PVC合成革的透水气性能依次下降,PU超细纤维合成革和PVC合成革经热老化后的尺寸稳定性相近且优于真皮.
Abstract
The structure and process of natural leather,polyurethane(PU)microfiber synthetic leather,and polyvinyl chloride(PVC)synthetic leather were compared,and the material properties were tested,compared,and analyzed.The results show that in terms of mechanics,PU microfiber synthetic leather has better comprehensive mechanical properties,superior to natural leather and PVC synthetic leather.In terms of bending performance,PU microfiber synthetic leather and PVC synthetic leather have similar bending performance,which is better than that of natural leather under conditions of humid heat aging,high temperature aging,climate aging,and low-temperature conditions.In terms of wear resist-ance,PU microfiber synthetic leather and PVC synthetic leather exhibit better wear resistance than natural leather.In terms of other material properties,the water vapor transmission of natural leather,PU microfiber synthetic leather,and PVC synthetic leather decreases sequentially.The dimensional stability of PU microfiber synthetic leather and PVC syn-thetic leather after thermal aging is similar and better than that of natural leather.
