| Abstract: |
| 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. |
