SOIL AND GROUND PROPPING COMPOSITION Russian patent published in 2013 - IPC C09K17/40 C08L33/00 E01C7/36 

FIELD: chemistry.

SUBSTANCE: invention relates to soil and ground chemical propping compositions and can be used in agriculture against water and wind erosion, as well as in construction of roads and other earth structures. The disclosed aqueous soil and ground propping composition contains 0.90-4.62 wt % of a charged polyelectrolyte complex and 0.08-0.87 wt % of a salt of an alkali metal or ammonia. The charged polyelectrolyte complex in said composition is a product of reacting water-containing solutions of a cationic polyelectrolyte, which contains chloride and bromide counter-ions, and an anionic polyelectrolyte from a group which includes a sodium salt of carboxymethyl cellulose, an alkali metal or ammonium salt of a polyacrylic acid or polymethacrylic acid, taken in a ratio where content of charged links of one polyelectrolyte ranges from 51% to 60% of the content of charged links of the other polyelectrolyte.

EFFECT: compared to the closest counterpart, the disclosed composition provides efficient soil and ground propping from wind erosion while reducing content of salt in the composition from 1,5-3,7 wt % to 0,08-0,87 wt % and consumption of the composition from 1-2 l/m² to 0,3-0,45 l/m².
