Mite-killing insect-preventing water-based inorganic nano-coating and preparation method thereof

The invention discloses a mite-killing and insect-preventing water-based inorganic nano-coating and a preparation method thereof. The mite-killing and insect-preventing water-based inorganic nano-coating is prepared from a mite-killing and insect-preventing agent, hydroxyethyl cellulose, a wetting agent, a dispersing agent, a defoaming agent, pigment, filler, a coalescing agent, an anti-freezing agent, modified inorganic nano-silicon emulsion, a flatting agent and water. The mite-killing and insect-preventing water-based inorganic nano-coating mainly forms covalent bonds with hydroxyl and amido in the modified inorganic nano-silicon emulsion paint film through the mite-killing and insect-preventing agent, and the mite-killing and insect-preventing effect is achieved by forming a mite-killing and insect-preventing medicine film through a coating film. The invention further discloses the preparation method of the mite-killing insect-preventing water-based inorganic nano coating. The preparation method of the wa
