| 中文摘要: |
| 以轻质碳酸钙为载体，制备氧化锌含量（质量分数）为30%，40%，50%和60%的核壳结构氧化锌，将核壳结构氧化锌与间接法氧化锌和活性氧化锌NC105进行对比，研究核壳结构氧化锌对天然橡胶（NR）胶料性能的影响及其在半钢子午线轮胎胎面胶中的应用。结果表明，氧化锌含量50%的核壳结构氧化锌与间接法氧化锌NR硫化胶和半钢子午线轮胎胎面胶的邵尔A型硬度、拉伸强度、拉断伸长率和撕裂强度相当，核壳结构氧化锌与活性氧化锌NC105胎面胶60 ℃时的损耗因子相差不大。核壳结构氧化锌胶料在减少氧化锌含量的同时性能保持不变或提升，达到了减锌提质的目的。 |

| Taking light calcium carbonate as a carrier，the core-shell structural zinc oxide with zinc oxide content （mass fraction） of 30%，40%，50% and 60% was prepared.The core-shell structural zinc oxide was compared with the indirect zinc oxide and active zinc oxide NC105 to study the influence of core-shell structural zinc oxide on the properties of NR compounds and it application in tread compound of steel-belted radial tire.The results showed that the Shore A hardness，tensile strength，elongation at break and tear strength of NR vulcanizates and tread compound of steel-belted radial tire with the core-shell structural zinc oxide with 50% zinc oxide content and the indirect zinc oxide were comparable.The loss factor at 60 ℃ of tread compound with the core-shell structural zinc oxide and active zinc oxide NC105 was not significantly different.The compounds with the core-shell structural zinc oxide maintained or enhanced its performance while reducing the zinc oxide content，achieving the goal of zinc reduction and quality improvement. |
