抗老化剂含量对聚丙烯纺粘土工布耐候性的影响及其自然-加速老化相关性研究
Influence of anti-aging agent content on weather resistance of polypropylene spunbond geotextiles and correlation between natural and accelerated aging
摘要
Abstract
To study the weather resistance of polypropylene(PP)spunbond geotextiles in outdoor engineering applica-tions,samples with different contents of anti-aging agents were prepared and their initial microstructure and mechanical properties were characterized.Subsequently,a natural aging test was conducted.By systematically analyzing the chang-es in mechanical properties,surface morphology,etc.,the influence of anti-aging agent content on the degradation behav-ior was investigated.The results showed that the anti-aging agent significantly inhibited the photo-oxidative degradation of PP,but excessive addition would lead to a decline in mechanical properties and processing performance.The sample with 3%anti-aging agent content had the best comprehensive weather resistance,which could delay the formation of car-bonyl products and the decline in mechanical properties,and also had a higher initial strength.Based on this result,an ar-tificial ultraviolet accelerated aging test was conducted on the sample with 3%anti-aging agent,and a correlation analy-sis was made with natural aging.The Schwarzschild law was used to establish an equivalent conversion equation model,linking indoor accelerated aging with outdoor natural aging.关键词
