| titleOfInvention | Process for the preparation of a suspension of silica in an optionally crosslinkable silicone matrix |
| abstract | The invention relates to the preparation of a suspension of precipitated silica in a silicone oil, this suspension being usable for the production of silicones crosslinkable by polyaddition or polycondensation (RTV elastomers). The object of the invention is to seek a compromise between on the one hand the cost and on the other hand the rheology and mechanical properties of the final RTVs. The invention achieves this object by providing a process for the preparation of a suspension of precipitated silica, treated with hexamethyldisilazane (HMDZ), in a crosslinkable silicone oil. This HMDZ is introduced in at least two fractions. The 1st fraction on the one hand corresponds to a proportion less than or equal to 15% by dry weight, based on the total amount of HMDZ, and on the other hand is first brought into contact with the precipitated silica and the water. The invention further relates to the production of a silicone elastomer composition from this suspension and to the composition thus obtained. |
