摘　　要：研究新型间苯二酚-甲醛树脂AR50在全钢载重子午线轮胎带束层胶中的应用。结果表明:加入间苯二酚-甲醛树脂AR50的胶料混炼过程中基本消除了烟雾和刺激性气味,大大改善了工作环境;采用间苯二酚-甲醛树脂AR50等量替代间苯二酚,胶料的t10延长约20%,有效提高了加工安全性,且有利于胶料中游离硫与钢丝帘线镀层中铜的界面粘合,胶料与钢丝帘线的初始粘合力提高了约6%,热氧老化、湿热老化和动态老化后的钢丝帘线抽出力保持率均有所提高,盐水老化后的抽出力保持率相当;硫化胶的定伸应力略增大,拉伸强度和拉断伸长率略减小,耐热空气老化性能和耐屈挠疲劳性能提高。The application of a new type of resorcinol formaldehyde resin AR50 in the belt compound of all-steel truck and bus radial tires was investigated.The results showed that,the addition of resorcinol formaldehyde resin AR50 basically eliminated smoke and irritating odors in the mixing process,and greatly improved the work environment.With the resorcinol formaldehyde resin AR50 instead of resorcinol in equal amount,t10 was extended by about 20%,which effectively improved process safety and facilitated the interface adhesion between free sulfur in the compound and copper in the steel cord coating.The initial adhesion between the compound and steel cord increased by about 6%,the retention rate of extraction force after thermal oxygen aging,wet and heat aging,and dynamic aging all increased,the retention rate of extraction force after salt water aging was equivalent.The tensile stress of vulcanizate slightly increased,the tensile strength and elongation at break slightly decreased,the hot air aging resistance and flex fatigue resistance were improved.
