摘要
将自主开发清洁生产工艺制备的不溶性硫黄充油产品HD进行全钢胎带束层大配合实验,结果表明,利用HD制得的硫化胶料的硬度、拉伸撕裂强度、黏合性能、分散性、回弹性、老化性能、覆胶性能等各项指标完全达到生产子午胎的相关标准要求。与不溶性硫黄国际领先产品Crystex HD OT20相比,采用自制HD不溶性硫黄的轮胎达到150km/h速度级别后发生冠空破坏的时间由2min延长到35min,在时速65km/h、负荷率增至150%级别后可持续运行51h才发生肩裂破坏,耐久时间延长约80%。采用自制不溶性硫黄HD轮胎的高速及耐久性能较Crystex产品有明显优势。清洁工艺制备的不溶性硫黄HD可应用于高性能全钢载重子午胎带束层。
The insoluble sulfur,HD,prepared by the self-developed clean production process was tested on the belt compound of all steel radial truck tire（TBR tire）. The physical properties of the vulcanized rubber,including the hardness,tensile splitting strength,adhesion,dispersity,rebound resilience,aging performance,could completely meet the standard requirements of the radial tire production. Compared with the imported insoluble sulfur（Crystex HD OT20）,HD exhibited better high-speed performance and durability. When the speed reached 150 km/h,the failure time of the tire prepared from HD was extended from 2 minutes to 35 minutes. As the load rate increased to 150% at the speed of 65 km/h,the tire made from HD were continually running till 51 hours and 42 minutes before destruction,an extension of the running time by approximately 80%. The results show that the self-made insoluble sulfur,HD,prepared by the cleaning process can be applied to the belt compound of TBR tire.
