Abstract
Disclosed herein are an anti-bacterial, anti-fungal and anti-viral composition with excellent sterilizing power, deodorization and adhesion activity, an application thereof, and a method for preparing the same. The composition with sterilizing activity against bacteria, fungus and virus comprises colloidal silver particles in an amount of from 11 wt % to 15 wt %, titanium dioxide nanoparticles in an amount of from 18 wt % to 25 wt %, a dispersion stabilizer in an amount of from 0.01 wt % to 10 wt %, a binder in an amount of from 0.1 wt % to 4 wt %, and a balance of water in an amount required to form 100 wt %.
Claims9
A method for preparing a composition showing sterilizing activity against bacteria, fungi and viruses, comprising
- i) reacting 15˜25 wt % of a silver precursor with 30˜50 wt % of a first alcohol in the presence of 0.1˜10 wt % of at least one dispersion stabilizer in a balance of water in an amount of 100 wt % to produce a silver colloid solution;
- ii) adding 15˜20 wt % of a titanium precursor, 10˜30 wt % of a second alcohol and 0.1˜10 wt % of an acid catalyst to a dilution of 10˜14 wt % of the silver colloid solution in a balance of water in an amount to 100 wt % of water to generate titanium dioxide nanoparticles in the silver colloid solution;
- and
- iii) adding 0.90˜26.6 wt parts of a binder to 100 wt parts of the silver colloid solution containing the titanium dioxide nanoparticles to form a combination particle,
- wherein the combination particle consists of a silver colloid bound to a titanium dioxide nanoparticle by a binder selected from the group consisting of acryls, urethanes, and epoxides.
