| 中文摘要: |
| 研究湿法氧化锌种类和用量对天然橡胶（NR）性能的影响。结果表明：与添加普通氧化锌的胶料相比，对于未填充炭黑NR体系，减半用量的湿法氧化锌混炼胶的焦烧时间和t90较短，Fmax较大；硫化胶的定伸应力、拉伸强度和剪切模量（G′）较大，拉断伸长率、损耗模量（G″）和损耗因子（tanδ）较小。对于填充炭黑NR体系，减半用量的湿法氧化锌混炼胶的门尼粘度、G′和G″较大，tanδ较小，焦烧时间和t90较短，Fmax较大；硫化胶的密度稍低，硬度和定伸应力较大，耐老化性能较好，玻璃化温度较低，tanδ较小，其他物理性能变化不大。湿法氧化锌FF的性能优于湿法氧化锌HR。 |

| The effect of the type and amount of wet process zinc oxide（ZnO） on the properties of natural rubber（NR）was investigated.The results showed that，compared with the compound added with ordinary ZnO，for the unfilled NR system，the scorch time，t90 of the mix added with half amount wet process ZnO were shorter，Fmax was higher，the modulus，tensile strength and shear modulus（G′）of the vulcanizate were larger，the elongation at break，and loss factor（tanδ）were smaller.For the NR system filled with carbon black，the Mooney viscosity，G′ and loss modulus（G″）of the mix added with half amount wet process ZnO were larger，tanδ was smaller，scorch time and t90 were shorter，Fmax was higher，density was slightly lower，the hardness and modulus of the vulcanizate were larger，aging resistance was better，glass transition temperature and tanδ were smaller，and other physical properties had little changed.The performance of wet process ZnO FF was better than that of wet process ZnO HR. |
