The application of domestic antioxidant 4020 in the carcass compound of all-steel truck and bus radial tires was studied.The results showed that by using domestic antioxidant 4020 instead of imported antioxidant 4020 in equal amounts,the Mooney viscosity of the compound was reduced,the Fmax was increased,and the t90 was shortened.The tensile property,tear strength and adhesive property of the vulcanizate were comparable,with a slight decrease in compression heat build-up.The durability of the finished tire was improved and the raw material cost was reduced.
