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

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 composition contains a polyelectrolyte, a water-soluble salt and water. The polyelectrolyte is a charged polyelectrolyte which is a reaction product of aqueous solutions of a cationic polyelectrolyte and an anionic polyelectrolyte, selected from a group comprising a sodium salt of carboxymethyl cellulose, an alkali metal or ammonium salt of polyacrylic acid or polymethacrylic acid, taken 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 the salt is an alkali metal or ammonium salt, or a mixture of such a salt with a calcium or magnesium salt, with the following ratio of components, wt %: reaction product 0.91-9.91; water-soluble salt of aqueous solutions of the cationic and anionic polyelectrolytes 0.10-0.62; water - the balance.

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