摘　　要：因印刷胶辊抗疲劳性能亟待提高,对比研究了印刷胶辊用CR(氯丁橡胶)与CR/S(氯丁橡胶/烯烃化合物)并用胶的屈挠疲劳性能,以及配方因素对CR/S并用硫化胶屈挠疲劳性能的影响。研究结果表明,牌号为PS40A的氯丁橡胶与S并用的硫化胶屈挠疲劳性能最佳;所选不同硫化体系胶料的屈挠疲劳性能由高到低依次为:硫载体硫化体系、EV(有效硫化体系)、SEV(半有效硫化体系)、CV(传统硫化体系);在满足硬度要求的前提下,随着炭黑粒径的增大,并用硫化胶的屈挠疲劳性能呈增高的趋势;防老剂并用体系中,BLE(9,9-二甲基吖啶)/4010NA(N-异丙基-N′-苯基对苯二胺)并用胶与4010NA/ODA(4,4'-二辛基二苯胺)并用胶的屈挠疲劳性能最好,BLE/4010NA并用体系加入抗疲劳剂M66后,硫化胶不出现龟裂的屈挠疲劳次数明显高于前者。In order to improve the fatigue resistance of printing cots,the flexure fatigue properties of CR and CR/S blends and the effects of formulation factors on the flex fatigue resistance performance of CR/S blending vulcanizates were studied.The results showed that the flexing fatigue performance of PS40A/S blending vulcanizates was the best.The order of flex fatigue properties of the different elected curing system vulcanizates from high to low were sulfur,EV,SEV,CV.Under the premise of meeting the hardness requirements,the flex fatigue performance of the blending vulcanizates showed an increased trend with the increasing of the carbon black particle size.During the blending antioxidant system,the flex fatigue properties of the BLE/4010NA blending vulcanizates and the 4010NA/ODA blending vulcanizates were among the best.The uncracked flex fatigue number of the BLE/4010NA blending vulcanizates with the addition of anti-fatigue agent M66 was significantly higher than the former.
