METHOD OF PREPARING SILICAS, SILICAS WITH SPECIFIC PORE-SIZE AND/OR PARTICLE-SIZE DISTRIBUTION AND THE USE 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 m<2>/g; a specific surface area BET (SBET) of between 45 and 550 m<2>/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. |
