摘要
为增强聚酰胺(PA)强度,用硅烷及钛酸酯等偶联剂对钛酸钾晶须进行表面处理,并考察钛酸钾晶须对PA力学性能、工艺性等影响.研究表明,钛酸钾晶须经硅烷偶联剂处理后,可改善复合材料性能,硅烷的表面处理效果较钛酸酯的好,并比较了硅烷偶联剂改性前后晶须对PA增强性能的改变.经硅烷偶联剂KH-550表面改性的PTW能与PA基体更好地相容,达到较好的增强效果.
Potassium titanate whiskers （PTW） were modified with several coupling agents in order to advance the PA matrix. Properties of potassium titanate whiskers modified PA Plastics were investigated. Surface treatment of whiskers by coupling agents such as silane and titanate were used to improve the interface properties between whiskers and Plastics. And the effects of PTW on the mechanical properties and processabilities of PA Plastics were studied too. It is concluded that silanecoupling agents have better surface treatment effects than titanate coupling agent and untreated whiskers. The results show that PTW can be perfectly combined with KH550 and then excellently reinforced the PA matrix.
