Abstract
Rubber, particularly vehicle tyres, is one of the market's most essential products. It also plays an important part in the production of goods. However, abrasions have been found as a factor influencing rubber goods. Wet and dry abrasions of deproteinised natural rubber (DPNR) with varying CB concentration were investigated. Abrasion tests were carried out with a pin-on disc tester and abrasive paper with high grain (Diamond 600) under various conditions such as load (5-25N), sliding speed (0.2618-1.3090m/s), sliding distance, time, and amount of water used. At load of 15N with sliding speed 0.7854m/s, DPNR 25 (25 wt.% CB) achieves its maximum and critical circumstances, when it deteriorates. At load of 25N with sliding speed of 1.3090m/s, DPNR 50 (50 wt.% CB) achieves its maximum and critical conditions, when it deteriorates. The results demonstrate that CB material has an impact. The results suggest that CB content influences the DPNR's behaviour. It has a significant impact on rubber abrasions. The higher the CB content, the higher the quality of the rubber products. It was also discovered that the sample size of the rubbing samples influenced the abrasions. It has been demonstrated that abrasion increases with increasing speed and load but reduces as it approaches the maximum load before deterioration. Finally, SEM pictures are used to examine the abrasion pattern of the rubber to match the experimental results to the wear mechanism and the element composition of the DPNR is examined through EDX analysis.
