Method of preparing silicas, silicas with specific pore-size and/or particle-size distribution, and the uses thereof, in particular for reinforcing polymers |
摘要 |
The invention relates to a novel method of preparing silicas and to highly-structured silicas having the following characteristics: a specific surface area CTAB (SCTAB) of between 40 and 525 m2/g; a specific surface area BET (SBET) of between 45 and 550 m2/g; an object size distribution width Ld ((d84-d16)/d50), which is measured by XDC particle size analysis after deagglomeration with ultrasound, of at least 0.91; and a pore-size distribution such that ratio V(d5-d50)/V(d5-d100) is at least 0.66. The invention also relates to the use of said silicas as polymer reinforcing fillers. |
