Definitions

  • Nanoparticles of the above-mentioned metals and/or their oxides with antimicrobial properties may be in the form of a colloidal solution.
  • the antimicrobial hydrophobizing liquid may further comprise 0.1 to 60 % by weight of thickening agents, which in a preferred embodiment are formed by cetyl alcohol and/or lanolin.
  • the antimicrobial hydrophobizing liquid contains the addition of ethyl acetate solution in an amount of 0.1 to 60 % by weight of the starting solution of methyl silicone resin or the starting aqueous methyl silicone emulsion.
  • the antimicrobial hydrophobizing liquid according to the invention is based on methyl silicone resin dissolved in xylene and, if necessary, thickened with conventional thickening agents, for example with cetyl alcohol or lanolin. Nanoparticles and/or microparticles of at least one of metals with antimicrobial properties, such as silver, copper, nickel, zinc, titanium, iron and/or their oxides, such as copper oxide, zinc oxide, titanium dioxide, are added to this solution, wherein mutual combinations of the nanoparticles and/or microparticles of these metals and/or their oxides are also possible.
  • An aqueous emulsion can be formed by adding water to a solution of methyl silicone resin in xylene.
  • the antimicrobial hydrophobizing liquid contains a solution of methyl silicone resin dissolved in xylene, with 15 to 70 % by weight of methyl silicone resin in a thickened solution (resin + xylene + thickening agents) or in an unthickened solution.
  • the xylene solution of this resin can be used alone as a hydrophobizing coating, however, in order to add nanoparticles and/or microparticles to the powder, it is advisable to thicken it with cetyl alcohol or lanolin, to limit the sedimentation of nanoparticles and/or microparticles with a content of up to 60 % by weight of a thickening agent.
  • the nanoparticles and/or microparticles of metals and/or their oxides with antimicrobial properties are added to the solution in powder form in an amount of 0.001 to 8 % by weight based on the total weight of the solution for nanoparticles and in an amount of 0.1 to 8 % by weight based on the total weight of the solution for microparticles, whereupon they are thoroughly mixed to ensure that they are evenly dispersed in the solution. This applies to both the unconcentrated and concentrated solution.
  • the mixing method is arbitrary, except for ferromagnetic metals, especially iron and nickel, where magnetic stirrers are not suitable.
  • the liquid After the application of the antimicrobial hydrophobizing liquid to the surface of the treated component, the liquid is able to harden even at normal room temperature.
  • a heat treatment may be carried out, namely by at least drying it at a temperature of at least 50 °C for at least 20 minutes. It is also possible to use firing at higher temperatures if the surfaces of thermally stable materials are being treated.
  • water is added for emulsification in an amount of up to 50 % by weight based on the total weight of the resulting emulsion.
  • This procedure also enables an alternative method to deliver nanoparticles into the resulting liquid, when instead of powdered nanoparticles, an aqueous solution of nanoparticles, a so-called colloidal solution of antimicrobial metals or their oxides, as well as their mutual combination, is used.
  • the nanoparticle size again ranges from 5 to 1000 nm and their concentration in an aqueous solution ranges from 0.01 to 20 g/l.
  • the resulting emulsion must be homogenized.
  • the nanoparticles and microparticles further stabilize the emulsion, and emulsification prevents their sedimentation.
  • the liquids with microparticles can be mixed (homogenized) again before use, especially if sedimentation of microparticles occurs.
  • a mixture of Ce to C14 hydrocarbons may also be added to the mixture to further improve the water-repellent properties of the resulting liquid.
  • Microparticles, nanoparticles, hydrocarbons, as well as ethyl acetate can be used alone or in mutual combination.
  • the liquid thus prepared must be mixed thoroughly before use, as the microparticles sediment quickly, but their significant aggregation does not occur.
  • Suitable methods of application of this antimicrobial hydrophobizing liquid are coating or spraying, wherein it is suitable to use it for applications where abrasion is not expected, nor are expected other risks of mechanical damage due to the worse tribological properties of the given microparticles and where equipment is available to mix the liquid before use, whether continuously or once just before use.
  • methyl silicone resin in xylene 5 % by weight of cetyl alcohol and lanolin were added in a 1/1 ratio relative to the stock solution of methyl silicone resin and 2 % by weight of copper microparticles up to 10 pm in size relative to the stock solution of methyl silicone resin in xylene.
  • the solution was mixed thoroughly to ensure uniform dispersion of the microparticles in the solution.
  • liquid prepared in this manner should be thoroughly mixed before use, even though in this example the sedimentation of microparticles is slower than in example 1 .
  • the application can be carried out by spraying or coating, the liquid being usable for applications where abrasion or other risks of mechanical damage due to the inferior tribological properties of the microparticles are not expected and where equipment is available to mix the liquid before use, either continuously or once just before utilization.
  • An antimicrobial hydrophobizing liquid is formed from a solution of methyl silicone resin in xylene with a proportion of 50 % by weight and a colloidal silver solution in which the silver particle sizes range from 5 to 100 nm, with a mass concentration of silver of 50 mg/l.
  • the proportion of the aqueous colloidal solution in the total weight of the liquid was 10 % by weight, the proportion of methyl silicone resin in the resulting solution was therefore 45 % by weight.
  • the emulsion is subsequently homogenized.
  • the nanoparticles do not sediment in the thus prepared liquid and the coating or spray has a higher abrasion resistance and is therefore suitable for applications where this resistance is needed.
  • An antimicrobial hydrophobizing liquid is formed from a solution of methyl silicone resin in xylene with a proportion of 50 % by weight and water, the proportion of which je 10 % by weight.
  • the proportion of methyl silicone resin in the emulsion obtained is 45 % by weight.
  • the liquid is homogenized and 5 % by weight of a thickening agent is added to it.
  • the liquid is modified by the addition of 1 % by weight of silver microparticles up to 20 pm in size and by the addition of hydrocarbons with a Ce to C14 content at a concentration of 1 ml/l of the aqueous emulsion of methyl silicone resin. Then the emulsion is homogenized.
  • the addition of hydrocarbons serves to improve the tribological properties of the coating or spray, and silver nanoparticles are highly antimicrobial.
  • the liquid prepared in this manner is suitable, for example, for applications with high requirements for resistance to microbial contamination.
  • An antimicrobial hydrophobizing liquid is formed from a solution of methyl silicone resin in xylene with a proportion of 50 % by weight and water the proportion of which is 10 % by weight.
  • the proportion of methyl silicone resin in the emulsion obtained is 45 % by weight.
  • the liquid is homogenized and 3 % by weight of a thickening agent is added to it.
  • the liquid is modified by adding 0.1 % by weight of silver nanoparticles up to 100 pm in size.
  • a solution of ethyl acetate is also added in an amount of 50 % by weight of the aqueous emulsion and the emulsion is homogenized.
  • Silver nanoparticles exhibit antimicrobial properties even at a minimum concentration and ethyl acetate is used to improve the useful properties of the coating or spray.
  • the liquid prepared in this manner is therefore again suitable for applications with higher requirements for antimicrobial properties.
  • the antimicrobial hydrophobizing liquid according to the invention is intended for the treatment of non-porous materials with a smooth surface, ensuring their hydrophobicity and antimicrobial properties, wherein these properties are achieved even when dried at room temperature. By drying at an elevated temperature, a significantly faster drying time and a slight improvement in surface hydrophobicity can be achieved.
