Abstract: The study investigated the application of a novel graphene like material SG3-G in ordinary
conveyor belt coverlay. By replacing N330 carbon black, the processing performance, physical and
mechanical properties, and dynamic heat generation performance of the adhesive were investigated. The
results showed that the substitution of SG3-G from 0 parts to 20 parts prolonged the t 10 and t 90 of the mixed
rubber; The Mooney viscosity decreased significantly; The hardness, tensile strength, and tensile stress of
vulcanized rubber slightly decrease; The change in elongation at break and permanent deformation at break
is not significant; The tear strength has significantly decreased, while the dynamic heat generation has also
decreased.
