REINFORCING FILAMENTS AND COMPOSITES, RESISTANT TO AGGRESSIVE MEDIUM Russian patent published in 2008 - IPC D06M13/507 C03C25/40 B32B13/12 B32B17/04 C03B37/22 C03C25/10 D06M11/01 

FIELD: chemistry.

SUBSTANCE: invention relates to technology of production of reinforcing filaments, namely, filaments in form of glass braids, covered with appret composition in form of water or water-free dispersion. Composition includes, at least one silane of general formula Si(R¹)(R²)(R³)(R⁴), where - R¹, R² and R³ are selected from: -H (except R³), -Cl, -O-R⁵, -O-R⁶-O-R⁵, -O-(C=O)-R⁵, -O-R⁶-(C=O)-R⁵; R⁵ and R⁶ - radicals, in which main chain contains 1-4 atoms of carbon; - R⁴= -R⁷-NHR⁸; R⁷ - radical, branched with at least two side chains, and main chain contains from 2 to 6 atoms of carbon; R⁸ = -H, -R⁹-NH₂, -R¹⁰-NH-R⁹-NH₂; R⁹ - radical, containing from 1 to 12 atoms of carbon, or carbonyl; and R¹⁰ - radical, in which main chain contains from 1 to 6 atoms of carbon.

EFFECT: production of reinforcing filaments and composites, resistant to aggressive medium.
