METHOD OF MODIFYING INORGANIC OXYGEN-CONTAINING GRANULAR MATERIAL, PRODUCT MADE THEREFROM AND USE THEREOF Russian patent published in 2011 - IPC C09C3/08 C09D5/03 C09D133/14 C08K9/04 B82B3/00 

FIELD: chemistry.

SUBSTANCE: method of producing modified inorganic oxygen-containing granular material involves the following steps: a) preparing a mixture of an aqueous suspension of inorganic oxygen-containing granular material and alkoxylated alcohol of formula where R₁ is C₁-C₈-alkyl or phenyl, C₄-C₈-cycloalkyl or phenyl, R₂ is a hydrogen atom or methyl, and n is an integer from 1 to 5; b) optional addition of a first resin and/or precursor of the first resin; c) adding a mixture of one or more cross-linking agents containing one or more elements selected from a group comprising Si, Al, Ti, Zr, B, Zn, Sn and V; d) optional addition of a second resin and/or precursor of the second resin to the obtained mixture. Water is optionally removed from the mixture at least partially before or during step b), c) or d) or after step d). Also, the precursor of the first resin can be converted to the first resin before, during or after step c) and/or the precursor of the second resin can be converted to the second resin after step d).

EFFECT: invention increases environmental safety and simplifies production of modified inorganic oxygen-containing granular material which is well compatible with resins.
