The invention provides a preparation method of a glass matte
coating material, and aims to solve the problem of rough hand feeling of
coating materials in the prior art. The preparation method is characterized by comprising the following steps: putting an
epoxy resin and an
acrylic resin into deionized water, carrying out first high-speed dispersion, continuously adding an
extinction material, carrying out second high-speed dispersion, sanding, adding an assistant and nano
colloid, carrying out third high-speed dispersion, adding a
hydrolysis-resistant
coupling agent, and dispersing. Accordingto the invention, the product is a pure water-based environment-friendly product, does not contain
formaldehyde, free TDI and
xylene toxic substances, and is environment-friendly, safe, fireproof, non-combustible and non-explosive; the water-based paint does not cause environmental
pollution before and after construction, does not damage
human health, and is a brand-new environment-friendly product; the glass
coating material has strong adhesion on glass, the matte coating film layer has strong
adhesive force on a paint film, the appearance is fine and smooth, and the texture is strong; and through dispersion and
grinding multiple times, the hand feeling is smooth.
