摘要: 以3-(3,5-二叔丁基-4-羟基苯基)丙酸和正丁醇为原料,采用酯化反应,合成了新型受阻酚防老剂。并采用红外光谱、热重分析及荧光测试对合成的防老剂结构进行表征。结果表明,合成的防老剂是3-(3,5-二叔丁基-4-羟基苯基)丙酸正丁酯。受阻酚防老剂最佳合成实验条件是回流时间8h、催化剂质量分数3.2%、丙酸与正丁醇物质的量比为1:2。采用力学性能测试、红外光谱、热重分析等方法研究了受阻酚防老剂对NR硫化胶的防护性能,结果表明受阻酚防老剂对NR硫化胶有显著的防老化作用,其防老化效果优于防老剂BHT,且对橡胶无色泽污染性。

Abstract: The hindered phenolic antioxidant was synthesized with 3(3,5ditertbutyl4hydroxyphenyl) propionic acid and nbutyl alcohol as raw materials by esterifying reaction. The antioxidant characterized by infrared spectroscopy and HNMR was 3(3,5ditertbutyl4hydroxyphenyl) nbutyl propionate. The optimal synthesis conditions were as follows: reflux time 8 h, the molar ratio of 3(3,5ditertbutyl4hydroxyphenyl) propionic acid to nbutyl alcohol 1∶2 and the catalyst amount 3.2% on the total reacts. The effects of hindered phenolic antioxidant on the protective effect of NR vulcanizates were studied by mechanical property testing, infrared spectroscopy, thermal analysis. These results indicate that the hindered phenolic antioxidant havepronounced antiaging properties, which is higher than those of BHT antioxidant. Besides, the synthesized hindered phenolic antioxidant had no color pollution for rubber.
