摘要
聚丙烯(PP)塑料是1种性能优异、应用广泛的材料.在PP塑料的二次回收利用过程中,其力学强度、热稳定性和抗老化性能仍有待进一步提高.因此,研究采用废弃的PP塑料,并通过简单的熔融塑化和再冷却的方法制备了滑石粉填充的PP共混物.添加滑石粉后,滑石粉中的—OH基团和PP碳链上的—CH3基团之间形成了氢键,使滑石粉填充的PP共混物的力学性能较原始PP塑料显著提升.当滑石粉的含量为10%时,其断裂能相比原始的PP塑料提高了近142%.因此,在二次回收利用PP塑料的过程中添加适量的滑石粉有助于进一步提升PP共混物的性能.
Abstract
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.
