电子辐照技术在全钢载重子午线轮胎生产中的应用

Application of Electron Beam Irradiation Technology in Production of Truck and Bus Radial Tire

针对全钢载重子午线轮胎过渡层,在50 kGy剂量下采用不同辐照加速电压进行电子束辐照。结果表明,过渡层胶料门尼粘度随着辐照电压升高而升高,t_(10)及t_(90)缩短,粘性下降,硫化胶物理性能变化不大。过渡层辐照减薄后,单胎质量减小,成品轮胎耐久性能基本无差异。

In this study, the transition layer compound of truck and bus radial tire was exposed to 50 kGy electron beam at different acceleration voltage.The test results showed that, Mooney viscosity of the compound increased as the acceleration voltage increased, while the t10, t90 and tackiness were reduced.The physical properties of the vulcanizates changed little.With the electron beam irradiation technology, the designed thickness of transition layer could be smaller, and thus the tire weight was reduced.The test results showed that finished tire possessed the same level of endurance performance.
