α-ZrP层状纳米片的修饰改性及其摩擦学性能

Preparation and Tribological Properties of Surfactant Modified α-ZrP Layered Nanosheets

  • 摘要: 采用一步水热法制备了阳离子表面活性剂修饰改性的α-磷酸锆(α-ZrP)纳米片. 利用X-射线衍射仪、傅里叶变换红外光谱仪、拉曼光谱仪、场发射扫描电镜和透射电子显微镜对α-ZrP纳米片在表面活性剂修饰前后的组成、晶体结构以及微观形貌进行了表征分析和观察,并对改性前后的α-ZrP在合成基础油PAO-6中的分散稳定性进行了对比分析,利用SRV-Ⅳ型微动摩擦磨损试验机对含有改性α-ZrP纳米片的PAO-6润滑油的摩擦学性能进行了研究. 结果表明:表面改性的α-ZrP纳米片在PAO-6润滑油中具有良好的分散稳定性,其作为添加剂时可显著提高润滑油的极压性能和抗磨损性能.

     

    Abstract: Surface-modified α-zirconium phosphate (α-ZrP) nanosheets were prepared by a one-pot hydrothermal method. The crystal structure and morphology of nanosheets were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, field-emission scanning electron microscopy and transmission electron microscopy, respectively. The dispersion stability of surface-modified α-ZrP nanosheets in poly alpha olefin (PAO-6) base oil was analyzed. By using an oscillating reciprocating friction and wear tester (SRV-Ⅳ), the tribological properties of the surface-modified α-ZrP nanosheets as additive in PAO-6 were investigated. The surface-modified α-ZrP nanosheets had good dispersion stability in PAO-6 lubricating oil. Besides, surface-modified α-ZrP nanosheets as an additive significantly improved the extreme pressure performance and anti-wear property of PAO-6 oil.
