摘要:

通过研究不同润滑剂的配方产品表面的摩擦因数、材料与基材的黏结性能和材料物理性能等参数,寻找符合要求的自润滑TPV材料。结果表明,采用大分子量的聚二甲基硅氧烷且添加量为5.0份时制得的TPV材料,表面的摩擦因数≤0.75且黏结性能和力学性能良好,在汽车玻璃装饰材料方面有良好的应用前景。

关键词: 摩擦因数, 黏结性能, 调控

Abstract:

In this study, the self⁃lubricating thermoplastic vulcanizate (TPV) materials for automotive applications were investigated, focusing on friction coefficient, substrate adhesion, and physical properties of various lubricant formulations. Experimental results demonstrated that TPV compounds incorporating 5.0 phr (parts per hundred rubber) of high⁃molecular⁃weight polydimethylsiloxane exhibited optimal performance, achieving a surface friction coefficient of ≤0.75 while maintaining excellent bonding strength and mechanical properties. These characteristics make the developed material particularly suitable for automotive glass trim applications, offering significant potential for improved performance in demanding decorative applications.

Key words: coefficient of friction, adhesion properties, regulation
