1. A preparation method of a nontoxic antiseptic mildew-proof nano coating is characterized in that the coating is calculated according to the mass portion,tetraethyl orthosilicate:

  • 6 parts by mass of a reaction solution,weakly alkaline aqueous solution;

    10 to 100 parts by mass of a water-soluble polymer,an aqueous hydrophobic treatment agent;

    0.1 part by mass of a stabilizer,aqueous FEVE resin;

    2 parts by mass;

    wherein the content of the first and second substances,the water-based hydrophobic treatment agent is one or more of perfluorooctanoic acid, short-chain saturated fatty acid, short-chain alkane trimethoxy or triethoxysilane;

    the water-based FEVE resin is a fluororesin or fluorocarbon resin taking water as a solvent;

    the weak alkaline aqueous solution has a pH value of 8-11,the weak base is lysine;

    the preparation method comprises the following steps;

    1) preparing a weakly alkaline aqueous solution;

    adding lysine into deionized water, and adjusting pH to 8-11;

    2) preparing a nano coating;

    adding tetraethyl orthosilicate into a weakly alkaline aqueous solution, continuously mechanically stirring for 10-60min, adding an aqueous hydrophobic treatment agent, continuously mechanically stirring for 12-48h, adding aqueous FEVE resin, and continuously mechanically stirring for 1-2h to obtain the nano coating.
