The invention relates to the field of compositions for chemical fixation of soils and can be used in agriculture to fight against water and wind erosion, as well as the construction of roads and other earth structures.

(A.S. USSR №1507771, CL 08L 33/00, 1989).

Closest to the claimed is known previously proposed structure for anchoring the soil and the soil is in the form of an aqueous solution of cationic and anionic polyelectrolytes (PE), water-soluble salt (a mixture of salts of an alkali metal or ammonium salt of calcium or magnesium) and water in the following ratio, wt.%:

anionic PE0,5-3,0
cationic PE0,5-3,0

salt of the divalent metal0.3 to 1.0
waterrest

(patent of Russia №2142492, CL SC 17/00, 1999) prototype.

The disadvantages of the known composition are sufficiently high content of salts and relatively high consumption rate of soil (1-2 l/m2), which inevitably leads to the salinization of the soil.

An object of the invention is to provide a composition for fixing soils and soils low in salt and low consumption rate.

This technical result is achieved only when a known composition for fixing soils in the form of an aqueous solution of the cationic and anionic, PH, soluble salts and water, the composition contains a salt of an alkali metal or ammonium and charged polyelectrolyte to the complex which is the product of interaction of aqueous solutions of cationic PE containing counterions chlorine or bromine, and anionic PE selected from the group comprising sodium carboxymethyl cellulose (sodium CMC), salt of an alkali metal or ammonium polyacrylic acid or polymethacrylic acid, taken in the ratio in which the content of charged parts of a single PE is from 51 to 60% of the content of charged parts of another PE, the following ratio, wt.%:

The proposed technical solution, as anionic PE you can use any water-soluble anionic PE selected from the group comprising sodium CMC, sodium salt PAK (sodium-PAK), potassium salt PAK (potassium-PAK), ammonium salt PAK (ammonium-PAK), sodium salt PMAC (sodium PMAC), potassium salt PMAC (potassium-PMAC), ammonium salt PMAC (ammonium-PMAC). As cationic PE you can use any water-soluble cationic PE containing counterions chlorine or bromine, for example, DMDAAC, polyhexamethyleneguanidine chloride (PMGH), alkilirovanny poly-M-vinylpyridin etc. While the molecular weight of the polymers may vary within wide limits, for example, from one kilodalton to several thousand kilodaltons. Water-insoluble polymers may be used in this solution.

The proposed structure can be obtained by mixing aqueous solutions of anionic PE and cationic PE. While PE is mixed with the total initial concentration of from 1 to 5 wt.% the ratio at which the content of charged parts of a single PE is from 51 to 60% of the content of charged parts of another PE.

Upon receipt of the proposed structure, the sequence of adding the individual components in principle irrelevant. It is possible to aqueous solution of anionic PE to add an aqueous solution of cationic PE or Vice versa. This can be used with ordinary tap, well or artesian water, and prepared in a special way, for example, distilled water. Mix dry anionic PE and cationic PE or mixing the suspension of these components in organic media does not lead to the formation of the product.

In this invention, one can use the product of the interaction of aqueous solutions anionnogo the PE and cationic PE with experimentally found optimal content of charged parts of one PE in relation to the content of charged units other PE from 51%to 60%. Thus the sign of the charge received PE in principle irrelevant, that is, in PE can prevail as anionic units and cationic units. The mass ratio between the original anionic and cationic PE can be determined by calculation, based on the total initial concentration, the desired ratio of oppositely charged parts of the PE and the molecular weight of the charged units. Here is an example calculation of the mass ratio for cationic polyelectrolyte DMDAAC with the molecular mass of a charged link 162 Dalton and anionic polyelectrolyte sodium-PAK with a molecular mass of a charged link 94 Dalton. To obtain from them the desired product with a content of positively charged parts DMDAAC 56% of the content of negatively charged parts of the sodium-PAK should take DMDAAC and sodium-PAK in the ratio of 0.56×162)/94, respectively, that is 90,7/94. Thus, the mass content will be DMDAAC 90,7/(90,7+94)=90,7/184,7=0,491, or 49.1% of the total initial mass of PE, and the content of sodium-PAK will make up 50.9% of the total initial mass of PE. Hence, to obtain, for example, 10,000 g of the composition with 4.9%of the initial concentration of PE, you must take DMDAAC in the amount of 490×0,491=240,6 g and sodium-PAK in the number 249,4, during the formation of the product of the interaction of aqueous solutions of cationic PE, anyonehave in the system resulting from the interaction of released counterions chlorine and sodium can be formed salt is NaCl. The amount of this salt will be equal to the mass of the polyelectrolyte - DMDAAC, the links of which are taken at disadvantage (240,6 g)multiplied by the molecular weight of NaCl (58,5 Dalton) and divided by the molecular weight of the charged component of this PE, i.e. 162 Dalton. Thus, in the course of obtaining the composition is formed (240,6×58,5)/162=86,9 g of NaCl or of 0.87 wt.%. The weight of the product of the interaction of aqueous solutions of cationic PE and anionic PE is equal to the total initial mass PE minus the number of the formed salt, i.e. 490-86,9=403,1 g or 4.03 wt.%. Thus, you will get 10.000 g of the composition containing the product of the interaction of aqueous solutions of cationic PE and anionic PE 4.03 wt.%, the content of water-soluble salts of NaCl to 0.87 wt.% and water content 95,1 wt.%. To obtain compounds of the other recipes you need to make the appropriate calculation.

In the claims the distinctive characteristic is the ratio of charged units taken Peh introduced in distinctive part of the formula. The validity of such an introduction is due to the fact that in the known technical solution, selected as a prototype, the content of charged parts of a single PE is 7.2 to 100% of the content of the links of the other PE (calculation carried out analogously to the description given in the previous paragraph), but in our from 51%to 60%. Thus, the experimentally observed on the and the optimal interval is another.

When the content of charged parts of one PE less than 51% of the content of charged units other PE worsen structural properties of the composition for fixing the soil and increases the consumption rate of the composition. When the content of charged parts of one PE product more than 60% of the composition becomes inhomogeneous.

The proposed technical solution, it has been experimentally found optimal content of the product of the interaction of aqueous solutions of anionic PE and cationic PE with the composition of from 0.90 to 4.62 wt.%. With less than stated, the content of the product is low efficiency fastening. With a larger content of the product increases the viscosity of the composition and increases the rate of its consumption for treated soil layer and achieve the desired efficiency of the fastening.

The presence in the composition it is a product of the interaction of aqueous solutions of anionic PE and cationic PE, and not just a mechanical mixture dissolved the above-mentioned polymers is confirmed by the results of the following experiments. In accordance with the invention to prepare an aqueous solution of the product of the interaction of aqueous solutions of anionic PE and cationic PE. Put the sample obtained in the cell ultracentrifuge and pick up the speed of rotation of the rotor ultracentrifuge thus, in order to provide quantitative (full) OS is the approval of the product. Make sure that the supernatant (supernatant) contains no free anionic PE, nor free of cationic PE. Then spend four control experiment: in the first centrifuged solution anionic PE in aqueous salt solution, the second aqueous solution of anionic PE in water, in the third centrifuged solution of cationic PE in aqueous salt solution, the second aqueous solution of cationic PE in water. The concentration of PE in the control experiments take is equal to the concentration of these components in the formation of the product. Centrifugation of the solutions separately taken PE is performed at the same speed of rotation of the rotor, in which there was complete precipitation of the product. When convinced that under these conditions neither the individual anionic PE or individual cationic PE not precipitate from solution. The totality of the results obtained clearly indicates that the mixing of aqueous solutions of anionic PE and cationic PE when stated in the claims ratio of oppositely charged parts of PE is accompanied by formation of a new product, which quantitatively includes both PE.

This product is interpolyelectrolyte complex, however, accurately describe its structure and composition is not possible.

It should be noted that d is nom the invention, we declare the true composition for fixing soils, and not a list of individual components that are required to obtain such a composition.
