Tripolyphosphate sodium suppresses the foam formation by the action of the pr-1D and PO-6K foaming agents in the process of preparation and use is malignant, and in the process of hydration of pores 7 of the cement cement sodium tripolyphosphate - affects the chemically 60 unstable compound — sodium hyposulfite, resulting in i dies partial or complete chemical decomposition of sodium hyposulphite with the formation of various compounds, 5

including water-insoluble, as well as free sulfur. The complex additive is practically not capable of leaching from the material with water on the basis of the proposed composition.

The use of butadiene styrene latex in an amount of less than 3.7 wt.% (Calculated on dry matter) significantly reduces the water resistance and adhesion of the material to the metal based on the composition, and using it in an amount of more than 9.3 wt.% (Calculated on dry matter) impractical because it does not lead to a further increase in any properties of the composition.

The use of sodium hyposulfite in an amount of 0.02 wt.% Does not provide sufficient resistance to drinking water from the material based on the composition of the two other components of the complex additive, sodium tripolyphosphate and PO-1D or POg-bK, and using it in an amount greater than 0.06 wt.% contributes to the partial premature coagulation of the latex in the preparation of the composition. The use of Nari tripolyphosphate in an amount of less than 0.01 wt.% sufficiently inhibits the foaming effect of the PO-1d and -PO-BC foaming agents, and the use of e It is impractical to use more than 0.04 wt, as the optimal amount of sodium tripolyphosphate is selected in accordance with the optimal amount of PO-1D or PO-6K.

. The use of PO-1D or PO-6K foam former in an amount of less than 0.01 wt% does not provide sufficient latex stability during preparation and use of the composite, as a result of which the latex prematurely partially coagulates and the water resistance of the material based on the composition decreases, and the use of the foaming agent -1D or PO-B in an amount greater than 0.04 wt.% Results in undesirable foaming during preparation and use of the composition.

Preparation of the proposed soy tava ..

After that, the calculated amounts of the components of the complex additive are dissolved in the mixture obtained, and the sodium tripolyphosphate, hyposulfite sodium 6K (if the components are dissolved, starting with PO-1D or PO-6K, then immediate latex coagulation is possible). Separated from latex, the calculated amount of Portland cement and, optionally, the calculated amount of natural quartz sand) is mixed with the calculated amount of water and, at the rapid mixing stage, the latex stabilized by the means described is introduced into the prepared mixture, and the mixture thus obtained is ready for use.
