Reclaimed rubber in-situ grafted with soybean oil as a novel green reactive plasticizer in SBR/silica compounds
Abstract
Polymer recycling and biodegradable polymeric materials are two major routes towards the sustainable development of polymer materials which contributes to the management of waste. In this regard, an eco-friendly approach is presented wherein high reclaiming degree of ground tire rubber (GTR) was achieved by low-temperature oxidation under swollen action of soybean oil. In-situ reclaimed GTR with soybean oil was cured into reactive plasticizer (RP) through a free-radical chain reaction between activated molecular rubber chains and soybean oil. During the curing process, degraded rubber chains were involved in synergistic reactions of recombination to strengthen bound rubber involved with core-shell structure carbon black and grafting with soybean oil. RP was obtained by modification of highly reclaimed rubber to control leachable oils and to modulate the reaction. Reactive plasticizers are further explored as a multifunctional additive to styrene-butadiene rubber/silica compounds. Reactive plasticizers performed the following three functions towards styrene-butadiene rubber/silica compounds: i) value-added rubber substitute; ii) reinforcing filler with the increase in tensile strength maximum up to 112% approximately on account of bound rubber involved with core-shell structure carbon black; and most importantly, as a iii) reactive plasticizer.
