In the experiment,oleamide was added to styrene-butadiene rubber (SBR)/cis-butadiene rubber (BR) in different parts,and the properties of the rubber compound were characterized by vulcanization characteristics,mechanical properties and friction coefficient.The results showed that with the increase of the number of oleamide,the friction coefficient of vulcanizate was significantly reduced,and the elongation at break and flexural strength of vulcanizate were significantly improved.When the amount of oleamide in vulcanizate was 10 parts,compared to the group without oleamide,the tensile strength decreased by 19.84%,the elongation at break increased by 36.14%,the hardness decreased by 9.21%,the static friction coefficient decreased by 45.51%,and the dynamic friction coefficient decreased by 37.54%.The rubber compound was studied by rubber processing performance,differential scanning calorimetry and scanning electron microscopy.It was found that oleamide can make the vulcanized rubber spray more easily under the action of external force,and the friction coefficient became smaller.
