| 中文摘要: |
| 研究热稳定剂YG在无印痕实心轮胎中的应用。结果表明：加入热稳定剂YG的胶料的门尼粘度略微降低，胶料的分散性、挤出性能和流动性改善，满足实际生产工艺要求；与生产配方硫化胶相比，加入热稳定剂YG的试验配方硫化胶的拉伸强度和拉断伸长率增大，耐屈挠龟裂性能和耐磨性能提高，压缩屈挠温升减小，热氧老化后拉伸强度变化率和拉断伸长率变化率减小，试验配方硫化胶的物理性能更优异；生产和试验配方成品轮胎的耐久性能相当，且采用试验配方生产无印痕实心轮胎在行驶过程中无印痕、变色轻、磨损减轻，有利于延长轮胎的使用寿命。 |
| 英文摘要: |
| The application of heat stabilizer YG in non-footprint solid tires was studied. The results showed that，by adding heat stabilizer YG，the Mooney viscosity of the compound was slightly reduced，and the dispersibility，extrudability and fluidity of the compound were improved which met the actual production process requirements. Compared with the production formula vulcanizate，the tensile strength and elongation at break of the test formula vulcanizate added with heat stabilizer YG increased，flexural cracking resistance and abrasion resistance improved，and the compression flexural temperature rise decreased，the change rate of tensile strength and elongation at break after thermal oxygen aging decreased，indicating that the physical properties of test formula vulcanizates were better. The durability of the finished tires of the production and test formulas was equivalent，and the non-footprint solid tires produced by the test formula had no-footprint during the driving process，the discoloration was light and the wear was reduced，which was beneficial to improve the service life of the tire. |
