FIELD: protective materials.
SUBSTANCE: multilayer protective material contains at least two layers, one of which, which is external to the protected surface, is made of a hydrophilic porous material containing a silver-containing component and an acidic agent, encapsulated in the pores of the material and providing an increase in the concentration of silver ions in water when wetting the material with it. The porosity of the hydrophilic material is selected in the range of micropores or mesopores to ensure the prolonged release of the acidic agent encapsulated in the pores. The inner layer is made of a fibrous hydrophobic material.
EFFECT: invention is aimed at ensuring the removal of liquid from the protected surface and preventing the growth of microorganisms during repeated moistening and drying of the protective material due to the low rate of release of the acidic agent.
