NANOMODIFIER OF CONSTRUCTION MATERIALS AND METHOD OF ITS PRODUCTION Russian patent published in 2013 - IPC C04B24/00 B82B1/00 

FIELD: nanotechnology.

SUBSTANCE: nanomodifier of construction materials and method of its production can be used in construction technology. The nanomodifier of construction materials comprising a mixture containing carbon nanomaterial (CNM), a filler and a plasticiser, and the CNM is added in the form of nanotubes "Taunit", as a plasticiser the mixture contains polyvinylpyrrolidone, as a filler - polyethylene glycol PEG-1500, and additionally contains sodium hydro-carbonate and citric acid with the following components ratio, wt %: CNM "Taunit" 0.1-8, polyvinylpyrrolidone 0.1-8, sodium hydro-carbonate 5.5-11.5, citric acid 5.5-11.5, polyethylene glycol PEG-1500 - the rest. In the method of production of the nanomodifier of construction materials from the said mixture the nanomodifier is made in the form of effervescent tablets containing CNM "Taunit", basic and acidic components of the effervescent degree, tableting of anhydrous components is carried out by melting the polyethylene glycol PEG-1500 at a temperature above the temperature of its crystallisation, the molten polyethylene glycol PEG-1500 is divided into two parts, the citric acid, polyvinylpyrrolidone and CNM "Taunit" is added to one part and mixed, the sodium hydro-carbonate is added to the second part, and before feeding the melt to the mould the resulting mixtures of melts are filled into the preheated process chamber of a planetary mill and is processed in it for 30 min at a temperature of 75 or 80°C, after that the melt is poured into the moulds with their subsequent cooling. The invention is developed in the dependent claims.

EFFECT: increase of strength of construction materials.
