Process for obtaining silane derivatives of sepiolite by reaction with alkoxy-silanes to improve their reinforcing capacity in polymers |
摘要 |
The present invention relates to a process for obtaining dilane derivatives of sepiolite by reaction with alkoxy-silanes to improve their reinforcing capacity in polymers, the reaction being carried out by placing the finely divided sepiolite and the alkoxy-silane in close contact, either by vaporization of the latter by the action of heat or by the spraying thereof with nitrogen, the contact taking place in countercurrent in a column of suitable dimensions, the reaction temperature ranging between room temperature and the vaporization temperature of the alkoxy-silane, further characterized in that the silane derivative of the sepiolite is subsequently dried to 110 DEG C. to remove the reaction byproducts.
