Mullins Effect under Compression Mode and its Reversibility of Thermoplastic Vulcanizate Based on Ethylene-Vinyl Acetate Copolymer/ Styrene-Butadiene Rubber Blend

关键字:

摘要:The Mullins effect during uniaxial compression tests, together with its reversibility of the styrene-butadiene rubber (SBR)/carbon black (CB) vulcanizate and ethylene-vinyl acetate copolymer (EVA)/SBR/CB thermoplastic vulcanizate (TPV) were investigated systematically. The experimental results indicated that the Mullins effect could be observed during the cyclic uniaxial compression tests and accompanied with stress softening, residual deformation accumulation and hysteresis. The reversibility of the Mullins effect showed a temperature-dependence feature and was enhanced with increasing temperature. The morphology study showed that the SBR particles with average diameter of 10-20 mu m were dispersed evenly in the etched surface of EVA/SBR/CB TPV.
