| 中文摘要: |
| 分别以乙烯基树脂和改性聚氨酯为包覆壁材制备4种聚合物包覆硫黄产品，对其进行扫描电子显微镜分析，并研究其在轮胎胎面胶中的应用。结果表明：硫黄表面有明显的包覆层；用于胎面胶配方时采用聚合物包覆硫黄的混炼胶的加工性能、硫化特性以及硫化胶的物理性能与采用不溶性硫黄IS-7020的胶料相当。 |
| 英文摘要: |
| In this article，4 types of polymer-encapsulated sulfur product were prepared by vinyl ester resin and modified PU as the shell and analyzed by Scanning Electron Microscope （SEM）.The encapsulated sulfur was then studied in the tread compound of radial tires.The SEM test results clearly showed coated layers on the surface of the polymer-encapsulated sulfur products.When these products were used in radial tire tread formula，the processability and curing characteristics of the mixed compound and physical properties of the vulcanizate were similar to the compound with insoluble sulfur IS-7020. |
