Abstract

The invention discloses nanometer inorganic non-sticking water-based paint and a preparation method thereof. The paint is composed of components A and components B according to weight ration as 3:1. The components A are composed of silicon oxide sol, alumina seed crystal, yttrium oxide seed crystal, rutile titanium dioxide, nanometer silicon dioxide, black iron oxide, isopropanol, deionized water, carboxymethyl acetic acid butyrate cellulose and polyvinyl alcohol. The components B are composed of methyl triethoxy silane, tetraethoxysilane, metasilicic acid methyl ester, isopropanol and ethanol. The preparation method includes: mixing the components A and the components B of the paint according to the weight ration as 3:1, and stirring and curing for more than 12 hours in sealing mode at the temperature of 35 DEG C and under the condition of 200-300 rpm to obtain the nanometer inorganic non-stick water-based paint. The nanometer inorganic non-sticking water-based paint uses natural ore and metal oxide as raw materials, water is used as a dispersion medium in a preparation process, pollution of solvent in conventional paint on environment is solved fundamentally, and products do not contain volatile organic compounds (VOC).

Description

technical field [0001] The invention relates to water-based coatings, in particular to a nano inorganic non-stick water-based coating and a preparation method thereof. Background technique [0002] Traditional paints are oil-based paints with natural oils or resins and synthetic polymers as the main film-forming materials. Although oil-based paints have the advantages of chemical resistance, water resistance, wear resistance and good adhesion, the raw materials of oil-based paints must be Most of them come from the petrochemical industry, and organic solvents are used as the dispersion medium, resulting in the production and application of oil-based paints. During the production and application process, the solvents of the paints or the release of VOC from the paints will pollute the environment and seriously damage people's health. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a nano inorganic n...
