This article presents results on studying effect of multi-walled carbon nanotubes (CNTs) on the tribological properties of frost-resistant rubber based on epichlorohydrin rubber. The sliding friction coefficient has been determined using a laboratory tribometer according to the “rubber ring-smooth steel disk” contact scheme. Rubber samples have been tested under conditions of dry friction for ranges of normal pressures of 0.1 … 0.4 MPa, sliding velocities of 1 … 100 mm/s for two values of the bulk temperature: 23 and −25° C. The wear rate of the samples has been determined at a temperature of 23° C, pressure of 0.4 MPa, and sliding speed of 10 mm/s. As a counterbody in experiments on the wear resistance assessment, sandpaper made of silicon carbide with a grain size of 120 and 250 microns has been used. It has been found that using CNTs as a filler for studied rubbers leads to an increase in their wear resistance. There is a multiple decrease in the wear rate when filling rubber with a small amount of CNTs (1–2 pts. wt. per 100 pts. wt. of rubber). Moreover, an improvement in physical and mechanical characteristics while maintaining high frost resistance is established. The addition of CNTs to the studied rubbers does not affect the static coefficient of friction.

活性炭纳米管对防冻橡胶摩擦性能影响的研究

本文介绍了研究多壁碳纳米管（CNTs）对基于环氧氯丙烷橡胶的耐冻橡胶的摩擦学性能影响的结果。滑动摩擦系数已使用实验室摩擦计根据“橡胶环-光滑钢盘”接触方案确定。橡胶样品已经在干摩擦条件下进行了测试，其正常压力范围为0.1…0.4 MPa，滑动速度为1…100 mm / s，两种体温分别为23和-25°C。在23°C的温度，0.4 MPa的压力和10 mm / s的滑动速度下确定样品。作为耐磨性评估实验中的平衡体，已经使用了由粒度为120和250微米的碳化硅制成的砂纸。已经发现使用CNT作为用于研究的橡胶的填料导致其耐磨性的增加。当向橡胶中填充少量的CNT（每100重量份橡胶1-2重量份）时，磨损率会多次下降。此外，建立了在保持高抗冻性的同时物理和机械特性的改善。将碳纳米管添加到研究的橡胶中不会影响静态摩擦系数。
