AQUEOUS COMPOSITION FOR COATING OUTER, INNER, FRONT AND ROOF SURFACES, USE OF SILVER NANOPARTICLES (VERSIONS), USE OF AQUEOUS COMPOSITION, METHOD OF APPLYING COATING ON INNER AND OUTER BUILDING SURFACES Russian patent published in 2011 - IPC C09D5/14 C09D5/02 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to an aqueous composition for coating outer, inner, front and roof surfaces, having bactericidal action. The water paint composition contains elementary silver and at least one additional component selected from a group comprising a silver salt, chitosan and/or chitosan derivatives. The water paint composition contains at least one organic or inorganic binder, and can additionally contain ZnO nanoparticles with average size of 500 nm. The invention also relates to use of silver nanoparticles combined with at least one additional component selected from a silver salt, chitosan, chitosan derivatives and optionally ZnO nanoparticles as a bactericidal agent in aqueous compositions for painting inner, front, roof and outer surfaces. The method of applying the coating on inner, outer, front and roof surfaces of a building involves depositing the water paint composition.

EFFECT: obtaining a composition having highly efficient bactericidal action and does not have allergenic and toxic effect on the human body.
