Effect of molecular weight between cross-links on the abrasion behavior of rubber by a blade abrader

摘要: Abstract The effect of molecular weight between cross-links on the abrasion behavior rubber was investigated using acrylonitrile–butadiene (NBR), styrene–butadiene (SBR), and natural (NR) with a blade abrader. rate found to be almost constant irrespective cross-link density at low frictional input work, whereas it decreased minimum increased again as work increased. For rubbers high density, that slowly below critical abruptly above work. A similar phenomenon also in fatigue test. values test were very close fracture energies rubber. Thus, mechanical major mechanism changed from direct tearing As decreased, point not observed due energy In this range, fatigue, which confirmed by However, test-temperature lowering energy. rolling-type abraded surface occurred result thin layer peeling away abrasion.
