NANOMODIFIED EPOXY COMPOSITE Russian patent published in 2018 - IPC B82Y30/00 C08L63/00 C08K5/00 C08K13/04 C08J5/04 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer composites and is intended for the manufacture of heat-shielding coatings for hypersonic aircraft housings. Nanomodified epoxy composite comprising an epoxy resin, a curing agent, an inorganic filler and alumina or zirconium oxide nanoparticles, and/or yttrium oxide as a nanomodifier, wherein as a filler contains a quartz or silica woven fabric, and the nanomodifier is in the form of spheres obtained by the evaporation-condensation method, with the following component ratio, pts.wt.: epoxy resin 100, curing agent 10, filler 60–65, spherical nanoparticles Al₂O₃, or ZrO₂, and/or Y₂O₃ 17–22.

EFFECT: providing nanomodified epoxy composite, which has increased physical and mechanical characteristics and high erosion resistance.
