METHOD FOR PRODUCING MODIFIED SILICON DIOXIDE Russian patent published in 2017 - IPC C01B33/18 

Abstract RU 2616931 C1

FIELD: chemistry.

SUBSTANCE: invention relates to modified materials of silicon dioxide, used as fillers for rubber products, as adsorbents, grease thickeners, carriers (substrates). The modified silicon dioxide is obtained by powdering the FEDA phosphorus-boron-nitrogen-containing oligomer by fine-dispersed silicon dioxide when mixed at the weight ratio of silicon dioxide: FEDA phosphorus-boron-nitrogen-containing oligomer equal to 1:1.

EFFECT: reducing the silicon dioxide caking.
