PROTEINIC FOAM-PRODUCING AGENT AND METHOD FOR ITS PRODUCTION Russian patent published in 2015 - IPC C04B24/14 C04B38/10 

FIELD: construction.

SUBSTANCE: proteinic foam-producing agent for the production of porous construction materials includes, wt %: proteinaceous substance of microbiological synthesis - waste biomass of Aspergillus niger fungus of citric acid production 16, alkaline agent - mixture of slaked lime 2-4 and dust of electric filters formed during purification of exhaust gases of burning kilns of cement production, 0-2, stabilising additive in the form of 15% solution of metal salt solution, water - the rest. Method for producing the above mentioned proteinic foam-producing agent comprises mixing of protein-containing agent of microbiological synthesis, alkaline reagent, previously suspended in water, hydrolysis in the microwave field with frequency of 2450 Hz and power of 700 W during 20 minutes, cooling of mixture up to the room temperature, filtering, diluting of the obtained hydrolyzate up to the required foam-producing activity and stabilisation by the metal salt solution.

EFFECT: reduction of duration of the alkaline hydrolysis, waste utilisation.
