Abstract
The article proposes a redox mechanism for the bleaching of bentonite lump red clay and produces fillers for white paints and varnishes. Nanostructures of different types have been studied: intercalation compounds, delaminated nanocomposites, and mixed-type nanocomposites. Using the methods of IR spectroscopy, XRF analysis, laser diffraction, and DTA analysis, samples of synthesized organomodified bentonite were studied and the fact of intercalation of alkylbenzyldiethylamonium chloride molecules into the interlayer galleries of the crystalline inorganic matrix was established. A basic technological scheme for the production of bentonite fillers and organobentonite is presented. Nanocomposite hybrid paints and varnishes with the participation of new fillers and organobentonite have been obtained, and the physical and mechanical properties of new materials and coatings have been established.
