Abstract
The rare earth antioxidant was synthesized with 3-(3,5-di-tert-butyl-4-hydroxyphen-yl) propionic acid and lanthanum nitrate as raw materials.The antioxidant characterized by infrared spectroscopy,thermal analysis and fluorescence,was La complex.And the optimal synthesis conditions were as follows:the molar ratio of 3-(3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid to La(NO3)3 · H2O 2 ∶ 1 and reflux time 6 h.The effects of rare earth antioxidant on the protective effect of NR vulcanizates were studied by mechanical property testing,infrared spectroscopy,thermal analysis.These results show that rare earth antioxidant had pronounced anti-aging properties,which is higher than those of BHT antioxidant and equal to those of 4010NA.Besides,the synthesized rare earth antioxidant had no color pollution for rubber.关键词
