丁腈再生橡胶在光面轮胎胎面胶中的应用

Application of Reclaimed Nitrile Rubber in the Tread Compound of Smooth Tire

研究丁腈再生橡胶在光面轮胎胎面胶中的应用。结果表明:在光面轮胎胎面胶中加入丁腈再生橡胶,胶料的硫化速度变化不大,拉伸性能和耐磨性能略有下降,耐液体(油)介质性能明显提高;试验轮胎粘石子问题解决,使用性能优于生产轮胎,生产成本降低。

The application of reclaimed nitrile rubber in the tread compound of smooth tire was investigated. The results showed that the curing rate changed little with addition of the reclaimed rubber, the tensile properties and abrasion resistance of the vulcanizates decreased slightlY, but the oil resistance was significantly improved. The problem of stones or gravel sticking to the tread of the tire was solved, the overall performance of the finished tire was improved, and the production cost was reduced.
