PA66GF25尼龍隔熱條材料熱氧老化性的研究

發(fā)布日期：2014-10-17 來源：網(wǎng)絡(luò) 作者：方超

Influence of different antioxidants for aging time of nylon heat-insulation strip material （PA66-GF25） was studied in this article. The variety of tensile strength of nylon heat-insulation strip was used to characterize the effect of antioxidant systems. The results indicated that antioxidants prolonged the aging time of materials, the best was ternary compound that contains C-centered radical scavengers. Besides this, the static life of nylon heat-insulation strip materials were also predicted through theory of computation, the materials excluding antioxidant can use about 4.34 years, but that including ternary compound have 57.05-year life.
