| 中文摘要: |
| 采用活化剂450对废轮胎胶粉进行活化改性，并将再生橡胶与活化胶粉并用替代部分生胶用于力车轮胎胎侧胶。结果表明：随着活化胶粉用量增大，硫化胶的硬度和拉伸强度先大幅提高，后趋于稳定；再生橡胶用量较大时，硫化胶的拉断伸长率和撕裂强度较大。活化胶粉生产能耗低于再生橡胶生产能耗，应合理利用再生橡胶和活化胶粉。 |
| 英文摘要: |
| In this study，waste tire rubber powder was modified and activated by activator 450，and the application of reclaimed rubber and activated rubber powder in the sidewall compound of cycle tire was investigated.The experimental testing results showed that，with the increase of the addition amount of activated rubber powder，the hardness and tensile strength of the vulcanized rubber increased firstly and tended toward stable values.With more reclaimed rubber in the compound，the elongation at break and tear strength were higher.However，the energy consumption of the production for activated rubber powder was lower than that of reclaimed rubber.The use of reclaimed rubber and activated rubber powder should be rationally utilized. |
