FIELD: manufacturing functional compound additives.
SUBSTANCE: method is comprised of the following steps: extraction of nanocellulose fibres from non-wood biomass; hydrophobization of the surface of the extracted nanocellulose fibres; obtaining a powder of nanopowdered porous mineral; obtaining a complex composition based on nanocellulose fibres, which includes the following steps: vacuum dispersion of hydrophobized nanocellulose fibres and nanopowdered porous mineral powder; mixing hydrophobized nanocellulose fibres and nanopowdered porous mineral powder using a high-speed stirrer; and drying the blend of intermixed nanocellulose fibres and the nanoparticulate porous mineral, and preparing composite additives by melting and mixing the composite composition based on the nanocellulose fibres and either the polymer resin or the biodegradable resin.
EFFECT: compound additives with an antibacterial effect.
