| 中文摘要: |
| 对白炭黑的结构及其与橡胶性能的关系进行了研究。研究结果表明，白炭黑的结构分为一次粒子、二次粒子和三次结构。三次结构随制备条件的不同而变化，基本分为5种类型。白炭黑的三次结构是影响填充胶料物理性能的重要因素，其中在5种类型中第Ⅳ类结构产品的拉抻强度最大(17～20 MPa)。当白炭黑的理化指标均相同或相近时，可根据三次结构判别其产品性能的好坏。 |
| 英文摘要: |
| A study on the relationship between silica structure and vulcanizate properties was made.The results showed that the silica structure could be divided into three levels，i.e.the primary particle，the secondary particle and the third structure；the third structure could be devided into 5 types depending on the preperation conditions；the physical properties of reinforced rubber vulcanizate were effected signficantly by the third structure and the maximum tensile strength(17～20 MPa) was obtained by using the silica with the 4th type of the third structure；the quality of the silicas，which existed the similar physical-chemical indexes，could be evaluated based on their third structure. |
