    • PROBLEM TO BE SOLVED: To provide a polyamide resin composition improved in mechanical properties in a high-temperature atmosphere, and in surface smoothness.SOLUTION: The polyamide resin composition contains 100 pts.mass of a polyamide resin comprising a terephthalic acid component and a 8-12C straight-chain aliphatic diamine component, and 0.5 to 30 pts.mass of a fibrous clay mineral. Since the polyamide resin composition has both bending property in a high-temperature atmosphere and surface smoothness, the polyamide resin composition is excellent in heat resistance and rigidity as car engine peripheral parts, and can enhance high-temperature durability and supply and discharge efficiency in the case of being used for piping parts of engine supply and discharge systems.
    • 解决的问题:提供一种在高温气氛中提高机械性能和表面平滑性的聚酰胺树脂组合物。 解决方案:聚酰胺树脂组合物含有100质量份的包含对苯二甲酸组分和8-12C直链脂族二胺组分的聚酰胺树脂和0.5至30质量份的纤维状粘土矿物。 由于聚酰胺树脂组合物在高温气氛中具有弯曲性和表面平滑性,所以聚酰胺树脂组合物作为汽车发动机周边部具有优异的耐热性和刚性,并且可以提高高温耐久性和供给和排出效率 用于发动机排放系统的管道部件的情况。 版权所有(C)2013,JPO&INPIT
