Mechanical properties, morphology, and Mullins effect of thermoplastic elastomers based on polypropylene and waste ethylene-propylene-diene terpolymer powder compatibilized by styrene-butadiene-styrene block copolymer

摘要:Thermoplastic elastomers (TPEs) based on polypropylene (PP)/waste ethylene-propylene-diene terpolymer powder (WEPDMP) composites were prepared by melt compounding, and the composites were compatibilized by styrene-butadiene-styrene block copolymer (SBS). The effects of SBS compatibilizer on mechanical, morphological properties, and the Mullins effect of the TPEs were investigated systematically. Experimental results indicate that SBS had a good compatibilization effect on the PP/WEPDMP composites. Compared with PP/WEPDMP composites, the tensile strength and the elongation at break went through a maximum value at an SBS content of 6 phr, which were improved by 49.4 and 170.3%, respectively. Morphology study shows that the interface interaction of the PP/WEPDMP composites compatibilized by SBS was strong, which contributed to the significantly improved mechanical properties. Mullins effect results show that the softening obviously appeared after the second loading-unloading cycle, while the maximum stress decreased slightly at the later cycles and the internal friction loss of PP/SBS/WEPDMP composites was lower than that of PP/WEPDMP composites, indicating the elasticity of PP/WEPDMP TPE is improved by the incorporation of SBS.
