生物基聚酰胺56浸胶帘线的性能评价及应用进展

Performance Evaluation and Application Progress of Bio-based Polyamide 56 Dipped Cord

对生物基聚酰胺56(PA56)浸胶帘线的性能进行研究,并对其应用情况进行介绍。结果表明:PA56浸胶帘线具有较好的耐热性能、耐疲劳性能、粘合性能和动态力学性能;采用PA56浸胶帘线用作半钢子午线轮胎冠带层增强材料,生产从Q级到Y级的轮胎性能达到了采用传统石油基聚酰胺66浸胶帘线生产的轮胎水平,且具有降低碳排放的作用。

The properties of bio-based polyamide 56(PA56)dipped cord were investigated and its application was introduced.The results showed that PA56 dipped cord had good heat resistance,fatigue resistance,adhesion and dynamic mechanical properties.Using PA56 dipped cord as the reinforcement material for the cap ply of steel-belted radial tire,the performance of tires produced from Q-grade to Y-grade had reached the level of tires produced using traditional petroleum based polyamide 66 dipped cord,and had the effect of reducing carbon emissions.
