摘要
研究动态热机械分析仪测试条件对胎面胶动态力学性能测试结果的影响。结果表明:升温速率过快,会导致玻璃化转变温度和损耗因子(tanδ)测试值偏大;预拉伸形变(静态形变)过大,会导致tanδ测试值偏差变大;动态形变过大,会导致胶料滞后效应明显,tanδ测试值偏大;测试胎面胶性能时,应选择较小动态形变;测试胎侧胶性能时,应选择较大动态形变。
The effect of the testing conditions of dynamic thermomechanical analyzer on the testing results of dynamic mechanical properties of tread compound was studied. The results showed that the test results of glass transition temperature and loss factor(tanδ) were larger when the heating rate was too fast,large pre-stretching deformation(static deformation) would lead to larger deviation of tanδ test values,and large dynamic deformation would cause an obvious hysteresis effect of the compound and lead to larger tanδ test values. Therefore, smaller dynamic deformation should be chosen in the test of tread compound,and the larger dynamic deformation should be chosen for the test of sidewall compound.
