| titleOfInvention |
It is used to prepare the novel method of precipitated silica, novel precipitated silica and application thereof, particularly for enhancing polymer |
| abstract |
The present invention relates to a kind of novel methods for being used to prepare precipitated silica, in which: reacts silicate with acidulant, to obtain precipitated silica suspensions；The precipitated silica suspensions are filtered, to obtain filter cake；The filter cake is set to be subjected to being related to adding the operation splitting of at least one aluminium compound；It and is drying steps after the operation splitting.It is a feature of the present invention that at least one polybasic carboxylic acid is added in the filter cake during or after operation splitting.The invention further relates to novel precipitated silica with and application thereof. |
