摘要
研究增塑剂DOP对NBR/PP共混物物理性能、结晶性能及流变特性的影响。结果表明,随着增塑剂DOP用量增大,NBR/PP共混物的硬度明显降低,流动性能显著提高;增塑剂DOP用量对共混物的结晶性能影响不大;加入增塑剂DOP,共混物老化后的100%定伸应力和拉伸强度提高,拉断伸长率和流动性能下降。
The effect of DOP on the physical properties, crystallinity and rheology of NBR/PP TPV was investigated. The results showed that the hardness of NBR/PP TPV decreased and the flowability increased significantly with the addition level of DOP increased; the addition level of DOP had little effect on the crystal linity of TPV;and the modulus at 100% and tensile strength of aged TPV increased,and its elongation at break and flowability decreased by adding DOP.
