METHOD OF PRODUCING SOIL AND GROUND PROPPING COMPOSITION Russian patent published in 2013 - IPC C09K17/40 

FIELD: chemistry.

SUBSTANCE: invention relates to soil and ground chemical propping methods and can be used in agriculture against water and wind erosion, as well as in construction of roads and other earth structures. The method involves mixing aqueous solutions of an anionic polyelectrolyte and a cationic polyelectrolyte and a water-soluble salt. The polyelectrolytes are mixed with their total initial concentration ranging from 1 to 10 wt % in a ratio at which content of charged links of one polyelectrolyte is equal to 5-50% of the content of charged links of the other polyelectrolyte and concentration of at least one salt, selected from a group comprising an alkali metal salt, an ammonium salt, a calcium salt and a magnesium salt, ranges from 0.01 to 0.1 wt %.

EFFECT: low content of salt in the composition and lower consumption rate of the composition.
