A known method of manufacturing a building material, including the mixing of components, the molding of products, their heat treatment and cooling. C -

The disadvantages of the resulting products is low strength and a complete lack of electrical conductivity.

The aim of the invention is to impart electrically conductive properties to the material.

The goal is achieved by the fact that the raw material mixture for the manufacture of building material, including liquid glass, expanded granules of liquid glass, a filler and an additive, contains a colloidal graphite preparation as a filler, and as additives, quicklime and boric acid in the following ratio of components , m .:

/ Expanded liquid glass granules 20-50 Colloid-graphite preparation 5 18 Amorphous silica Nexen lime 2, 5 Bornic acid 0, Liquid glass Else graphite preparation and swollen granules of liquid glass, then the resulting mass is mixed with liquid

glass, amorphous silica, quicklime and boric acid, fill the mold with a mixture of 50-100 by volume, heat treatment is carried out at a temperature of 00-500 ° C for 1 hour, and cooling is carried out at a speed of 250-350 ° C per hour.

Construction products are manufactured according to the proposed method, as follows.

Initially, crushed expanded liquid glass was mixed (particle size 2.5 mm) and. colloid-graphite preparation, mixing time is 2 minutes, with a ratio of crushed glass: graphite powder 3: 1, by weight. Then, the resulting mixture is again mixed with liquid glass and an additive that controls the expansion of liquid glass, amorphous silica and boric acid and quicklime, at a 1: 2 ratio of this mixture and liquid glass. The amount of additive 5 by weight of liquid glass.

The resulting mass is placed in a form (plate size 1x2 m) with filling the volume of the form at 50, 75 and 100%. After that, heat treatment is performed at 00 ° C and 500 ° C for 1, 5 or 3 hours in a slit furnace, after which the product is cooled for 1.5 hours, i.e. with a speed of 250 or 350 C per hour.

A total of 5 mixtures were made.

The data are given in table. one.

The resulting mixtures are loaded into the product forms — a 0.7x2 m plate, after which the heat treatment is carried out for k hours, followed by cooling for 1 hour.

Characteristics of the material obtained products are given in table. No. 2

Thus, the proposed raw material mixture makes it possible to manufacture heat-insulating products with high strength and low bulk mass, while giving the material an electrical conductivity, which makes it possible to use it for both heat insulation and heating. This is the effectiveness of the invention.
