Mechanical and Aging Properties of Polypropylene and Styrene-Butadiene-Styrene Composites Under Outdoor and Indoor Conditions

Polypropylene (PP) and styrene-butadiene-styrene (SBS) blends with different mass fractions were prepared in a molten state using a twin-screw extruder. The effect of SBS content on the microstructure and properties of PP/SBS was discussed by studying the morphology and mechanical properties of PP/SBS outdoor aging samples, using differential scanning calorimeter, universal material testing machine, capillary rheometer, X-ray diffraction and X-ray photoelectron spectrometer. The results show that the best performance of unaged composites is 20% PP/SBS composites without added compatibilizer. Low temperature test combined with dynamic thermal analysis found that the addition of SBS effectively improved the low temperature brittleness of PP. XRD tests indicate that SBS can promote the formation of β crystals in PP. Indoor and outdoor aging tests show that samples with 30% of SBS has excellent long-term anti-aging properties.
