Effects of modified poly(tetrafluoroethylene) on the physico-mechanical and tribological properties of carbon-black filled nitrile-butadiene rubber
In this study the effects of electron beam irradiated poly (tetrafluoroethylene) (IR-PTFE) on the mechanical and tribological properties as well as thermal and solvent aging behavior of carbon black filled nitrile-butadiene rubber vulcanizates were studied. Based on the obtained results, addition of 30phr IR-PTFE reduced mechanical strength about 10%, whereas coefficient of friction desirably reduced up to 60%. It was shown that IR-PTFE significantly improved tribological properties by affecting the adhesion contribution of the friction mechanism. Moreover, formation of IR-PTFE transfer films also contributed to the reduction of coefficient of friction in the long term tests. In addition, it was explained that IR-PTFE enhances the sulfur cross-linking reaction in the vulcanizates by reducing the intensity of carbon black network. Therefore, augmented chemical cross-links compensates the loss of physical cross-links in the carbon black network and keeps the solvent swelling resistance unchanged. Also, IR-PTFE showed positive effects on the solvent aging of the vulcanizates, whereas the thermal aging of vulcanizates was unaffected.
