Abstract
The resource recycling of retired radial tires with excessive first harmonic radial force during the manufacturing process is difficult due to the high risk of damaging the tire body during traditional grinding repair.Taking two retired radial tires with excessive first harmonic radial force,namely 205/55R16 and 215/60R16,as the test objects,the"concentric drum correction+thermal stress relaxation"non-destructive regeneration process was adopted.Single-factor experiments were conducted to optimize the two core process parameters of heating temperature and the distance between the drum and the tire body.The test results showed that the optimal process parameters were a heating temperature of 170℃and a distance of 13.5 mm between the drum and the tire body.Under this parameter combination,the regenerated tires had no internal or external damage,and there was no stress rebound after storage for 4 h.The mechanical properties met the requirements of Indoor Test Method for Tire Performance of Passenger Cars(GB/T 4502-2023).T his process enables the recycling of waste products,significantly reducing solid waste,and provides an industrial technology solution for the green and circular manufacturing of the tire industry.关键词
