Reinforcing and plasticizing effects of reclaimed rubber on the vulcanization and properties of natural rubber

Abstract

The production of high-added value reclaimed rubber (RR) is of great signifi-cance for the sustainability of rubber industries. To green recycle waste rub-bers and broaden the application of RR, a RR material with potentialreinforcing and plasticizing effects on nature rubber (NR) composites are pre-pared by a thermo-oxidative reclamation process. The reclamation degree ofRR is controlled by adjusting the content of soybean oil. The plasticizing effectis demonstrated by the decrease of torque during vulcanization and theenhancement of elongation at break of NR/RR composites with the increasingreclamation of RR. The tensile strength of NR/RR composites is enhanced byadding the RR, and the existence of RR also improves the thermal stability andrheological properties of NR/RR composites. The formation of new bound rub-ber in NR/RR compound indicates the reinforcing ability of RR. In addition,the average particle size of RR reaches nano-scale according to scanning elec-tron microscope photographs and its dispersion in NR/RR compounds isimproved with the increasing reclamation degree of RR as shown in Payneeffect. This work demonstrates the reinforcing and plasticizing ability of theRR, which is beneficial to improving the added value of reclaimed and broad-ening its application.
