PROCESS FOR THE PREPARATION OF PRECIPITATED SILICAS PRECIPITATED SILICAS AND THEIR USES IN PARTICULAR FOR THE REINFORCEMENT OF POLYMERS
본 발명은, 실리케이트를 산성화제와 반응시켜 실리카 현탁액을 얻고; 상기 실리카 현탁액을 여과하여 필터 케이크를 얻으며; 상기 필터 케이크에, 선택적으로 알루미늄 화합물의 존재 하에, 액화 작업을 적용하고; 여기서, 액화 작업 동안 또는 그 후에 필터 케이크에 하나 이상의 폴리카르복실산을 첨가하는 것인, 신규한 침강 실리카의 제조 방법에 관한 것이다. 이는 또한 신규한 침강 실리카 및 이의 용도에 관한 것이다.
The invention relates to a process for the preparation of a novel precipitated silica, wherein: a silicate is reacted with an acidifying agent, so as to obtain a silica suspension; said silica suspension is filtered, so as to obtain a filter cake; said filter cake is subjected to a liquefaction operation, optionally in the presence of an aluminium compound; wherein at least one polycarboxylic acid is added to the filter cake, during or after the liquefaction operation. It also relates to a novel precipitated silica and to its uses.
