Study on the Properties of Talc Filled Polypropylene Blends
Polypropylene(PP)is a widely used material with excellent properties.The mechanical strength,thermal stability,wettability,and anti-aging properties of PP can be further improved,especially for secondary recycled PP.Therefore,the study aimed to improve the properties of PP by waste PP and preparing talc-filled PP blends via a simple melt plasticization and re-cooling process.Through the addition of talc,hydrogen bonds were formed between the—OH groups in talc and the—CH3 groups on the PP carbon chain,resulting in a significant improvement in mechanical properties compared to virgin PP.The addition of 10% talc increased the fracture energy of the blends by nearly 142% .Therefore,the addition of talc in the secondary recycling of PP can effectively improve the performance of PP blends and enhance their sustainability in practical applications.
