Investigation on the Relationship Between Physical Properties and Rubber Abrasion Resistance

The abrasion and abrasion resistance of rubber has been intensively studied by various research groups in both academic and industrial fields. Despite such extensive investigations, the exact mechanism that occurs during abrasion continues to be the subject of debate. In general, it is believed that rubber abrasion is a surface fatigue fracture caused by friction in the interface between the rubber and harder materials with rough surface. Therefore, it can be expected that those properties that can prevent or retard such fatigue process, such as high elastics modulus, hardness, strength, should be the positive factors for improving abrasion resistance of rubber. However, it was seldom to report the exact relationship between rubber’s physical properties and its abrasion resistance. This paper is intended to investigate the relationship between physical properties and abrasion resistance. For this work, styrene butadiene rubber (SBR) is mixed with different carbon blacks such as N110, N220 and N330. The effect of different fillers on the Physical properties of SBR is measured. The relationship between these physical properties and abrasion resistance is studied in detail.
