Abstract
Graphene oxide (GO) has a large specific surface area, and the filler agglomeration is serious when it is mechanically mixed in open mill or internal mixer, which is unable to give full play to the layer isolation effect of GO to better improve the oil and high temperature resistance of NBR composites. Therefore, in this paper, the change rate of mass and volume, oil resistance, high temperature resistance, tear properties, Payne effect and mechanical properties of NBR composites prepared by dry mixing process, ball-milling modified GO/silica/si69-dry mixing process, NBR flocculation process, and ball-milling modified GO/silica/si69-NBR co-flocculation process were investigated. The results showed that compared with the GO/silica/NBR composites prepared by dry mixing, the change rate of tensile product and abrasion volume of the GO/silica/NBR composites prepared by ball milling-co-flocculation process after high-temperature and oil bath were reduced by 35.28% and 16.69%, respectively, and the tear strength was increased by 57.28%, which possessed excellent oil resistance and high temperature resistance, providing new technical guidance for the application of GO in oil and high temperature resistant NBR systems.
