FIELD: chemistry.SUBSTANCE: invention relates to method of obtaining modeling mass with biocidal properties. Organosiloxane is mixed with boric acid and Lewis's acid, obtained mixture is heated, biocidal additive and, at least, one additive, selected from group, which includes filling agent, pigment, plasticiser, are introduced. Boric acid is taken in amount 4-40 wt.f. per 100 wt.f. of organosiloxane, Lewis's acid is taken in amount 0.001-3 wt.f. per 100 wt.f. of organociloxane, as biocidal additiove silver nanoparticles in amount 0.00001-0.1 wt.f. per 100 wt.f. of organosiloxane are taken. Silver nanoparticles are introduced under heating, heating being performed by superhigh-frequency irradiation to temperature 100-50°C for 10-90 minutes.EFFECT: invention makes it possible to simplify known method of obtaining modeling mass for and increase its biocidal properties by 40-70 times.1 tbl, 18 ex |
