| 中文摘要: |
| 研究丁苯橡胶（SBR）和配合剂（氧化锌和硫黄）对沉淀法白炭黑性能鉴定测试结果的影响。结果表明：同一产地不同批号SBR对胶料的300%定伸应力、拉伸强度和拉断伸长率有一定影响；与采用橡胶用活性氧化锌的胶料相比，采用分析纯氧化锌的胶料300%定伸应力略高，拉伸强度和拉断伸长率较低；不同粒径硫黄对胶料性能有不同程度影响，尤其对拉伸强度和拉断伸长率的影响较大。在沉淀法白炭黑性能鉴定中应对橡胶和配合剂慎重选择。 |
| 英文摘要: |
| The effect of styrene-butadiene rubber（SBR） and compounding agents（zinc oxide and sulfur）on the performance evaluation of precipitated silica was studied.The results showed that different batches of SBR from the same production site had some effect on the modulus at 300% elongation，tensile strength and elongation at break.Compared with the compound with active zinc oxide，the modulus of the compound with analytical grade zinc oxide was slightly higher，and the tensile strength and elongation at break were lower.The particle size of sulfur showed influence on the properties of the compound，especially tensile strength and elongation at break.It was important to precisely control the selection of rubber and compounding agents in the performance evaluation of precipitated silica. |
