A method of preparing a surface treated barium sulfate product is disclosed which has improved dispersibility in end use applications such as polymeric formulations. The method includes mixing a silicon-hydride containing polysiloxane, in neat or in aqueous emulsion form, with a quantity of barium sulfate particles and then optionally drying the resultant mixture. The silicon-hydride containing polysiloxane is deposited on and chemically bonded to the surface of the barium sulfate particles.
L'invention concerne un procédé de préparation d'un produit de sulfate de baryum traité en surface, à la dispersibilité améliorée dans des applications d'utilisation finale telles que des formulations polymériques. Ce procédé consiste à mélanger un polysiloxane contenant de l'hydrure de silicium, sous forme d'émulsion pure ou aqueuse, avec une certaine quantité de particules de sulfate de baryum, puis éventuellement à sécher le mélange obtenu. Le polysiloxane contenant de l'hydrure de silicium est déposé et chimiquement fixé sur la surface des particules de sulfate de baryum.
