Studying the physical and mechanical properties of Acrylonitrile butadiene rubber / carbon / clinke

Abstract

This research studies the effect of adding the clinker as a filling material on the properties of Acrylonitrile
butadiene rubber NBR ،by means of preparing rubber blends containing different percentage (0,5,10,15,20 Phr) of the
clinker (Semi made-cement) ،on two roll mill. Physio -mechanical and chemical properties of the prepared blends were
described by testing them for tensile strength and abrasion resistance, values of hardness and swelling in different
solvents. Results revealed a decrease in the tension resistance for rubber blends c/k at the percentage of 45% with
increase of the percentage of the clinker added with the above mentioned rubber blends ,Also ,values of hardness
decreased direct proportional at a percentage of 19% with increasing the clinker ,percentage whereas, the friction
resistance decreased at a percentage of 254% with increasing the clinker percentage ,but according to elongation ,the
results were quite different from the previous results so that its percentage increased when cutting gradually with the
value of 266%when percentage of added clinker increased. Results of the study also, revealed that swelling of the
samples containing only the black carbon (C45K0) was low comparing with the samples containing the clinker.
