摘要： The invented antibacterial preparation based on silver on an inorganic carrier, exhibiting bacteriostatic to biocidal activity for a wide spectrum of microorganisms, particularly in polymers, water dilutable solvent systems and organic systems comprises 1.10e-6 to 7.2 percent by weight of metallic colloidal silver, and 1.33.10e-6 to 15.67 percent by weight of at least one silver halide being selected from a group comprising silver chloride, bromide and iodide. Balance up to 100 percent by weight represents inorganic carrier, consisting of microparticles with particle size ranging from 0.1 to 30 micrometers of at least one compound being selected from a group comprising aluminium oxide, silicon dioxide and titanium dioxide, aluminium hydroxide, magnesium carbonates and magnesium, calcium and barium double carbonates, aluminosilicates and double aluminosilicates of lithium, sodium, potassium, magnesium, calcium and barium. Ratio of the total amount of halides to total amount of silver in both the forms ranges in summary molar ratio from 1.10e-6 to 1 mole. The proposed antibacterial preparation can further contain binding components with grain size ranging from 0.1 to 30 micrometers and in amount within the range of 0.5 to 40 percent by weight. The binding component can be represented by at least one compound being selected from a group comprising phosphates, hydrogen phosphates, diphosphates, dihydrogen phosphates, sodium, potassium, calcium and magnesium phosphinates, and calcium and magnesium hydroxide.
