| 中文摘要: |
| 研究抗龟裂剂D-99在农业子午线轮胎胎面胶和胎侧胶中的应用。结果表明：添加2份抗龟裂剂D-99，胎面胶和胎侧胶的挤出和成型工艺性能良好，硫化特性和拉伸性能变化不大，生热降低，弹性、耐屈挠龟裂性能、耐磨性能、耐热老化性能和耐天候老化性能提高；成品轮胎的物理性能改善，使用寿命延长。 |
| 英文摘要: |
| The application of crack resistant additive D-99 in the tread compound and side wall compound of agriculture radial tire was investigated.The test results showed that，when the addition level of D-99 was 2 phr，the extruding and forming process of tread compound and side wall compound was good，curing characteristic and tensile properties changed little，heat build-up was reduced，elasticity，flex crack resistance，abrasion resistance，heat aging resistance and weathering resistance were improved，the physical properties of finished tire were improved，and the service life was prolonged. |
