The closest in technical essence and the achieved result

To the proposed is silicate putty 2j including, by weight; Liquid glass 38 Lead glut II Andesitic flour 100 A disadvantage of the known putty is the insufficient adhesion of the lining, and its permeability to aggressive media is relatively high.

The purpose of the invention is to increase the adhesion of the lining, as well as to reduce its permeability to cooking acid with soluble bases.

This goal is achieved by the fact that a polymer silicate putty for a lining device on a concrete base, including liquid glass, lead lame and andesitic flour, additionally contains tetrahydrofurfuryl alcohol and hydrochloric aniline at the following ratio of components, parts by weight:

Liquid glass 44-46 Lead ice 4-5 Andesite flour 95 Tetrahydrofurfuryl alcohol 0.45-0.5

Aniline sulfate 0, 26-0.28 The polymeric silty putty is prepared as follows.

A mixture of andesitic flour, lead fiber and aniline hydrochloride is prepared. B. The andesitic flour used, the content of carbonates should not exceed 0.4%, the flour should also not contain impurities of creamy sodium hydroxide. Tetrahydrofurfuryl alcohol is introduced into the liquid glass.

And the mixture is thoroughly mixed for 1.52 minutes, while not allowing this to form a gel.

With the intensive mixing, the prepared binder is introduced gradually in small portions by a mixture of andesitic flour, lead glue and aniline hydrochloride. The whole mass is thoroughly mixed, laid into forms and vibrated by tapping the forms for 3-4 minutes.

The determination was carried out in cooking acid concentration S0 (i 9.2-9.8%, NaQ.O (NH4.) OO - 0.82%, PH 1.5-1.8; 138 ° C; 0.7-0.8 MPa; I h. The proposed polymer silicate putty is corrosion-resistant and impermeable to the action of cooking acid with soluble base species, adheres to both portland cement and ceramic tiles, i.e. it can be used to obtain a single-layer lining in equipment, containing a concrete sublayer. Formula of the Invention Polymer silicate putty for a lining device on a concrete base including liquid glass, lead glaze and andesitic flour, characterized in that, in order to improve the adhesion of the lining, as well as to reduce its permeability. Table 2 95.6 99.0 Permeable For 20 min without penetration to the cooking acid with soluble bases, it additionally contains tetrahydrofurfuryl alcohol and hydrochloric acid aniline in the following ratio of components, parts by weight: Liquid glass 44-46 Lead oat 4-5 Andesitic flour 95 Tetrahydrofurfuryl alcohol 0.45- 0.5 Sulphate anilia 0.26-0.28 Sources of information taken into account during the examination 1.
