Embodiment 1

[0010] A kind of waterproof nano water-based coating described in the present embodiment 1, is made up of the composition of following mass fraction: 7 parts of nano-magnesium dioxide, 5 parts of nano-titanium dioxide, 6 parts of nano-alumina, 6 parts of nano-silicon dioxide, 8 parts Parts of nano-iron dioxide, 8 parts of nano-copper dioxide, 8 parts of nano-tin dioxide, 8 parts of nano-zinc dioxide, 8 parts of nano-sodium dioxide, 8 parts of activated carbon, 5 parts of pure acrylic copolymer emulsion, 5 parts of rutile Titanium dioxide, 3 parts of diatomaceous earth, 5 parts of aluminum silicate, 4 parts of gypsum powder, 1 part of thickener, 1 part of dispersant, 0.5 part of alcohol modified polyurea, 0.2 part of propylene glycol, 0.3 part of glycerin, 2 parts of polyurethane , 2 parts of isopropanol.

[0011] Further, the thickener is a mixture of polyacrylamide, polyvinyl alcohol, polyvinylpyrrolidone, polyethylene oxide, modified paraffin resin, carbomer resin, polyacryl...

Embodiment 2

[0014] This embodiment 2 is changed on the basis of embodiment 1, mainly because the composition of the thickener is different. A mixture of vinyl waxes.

Embodiment 3

[0016] This embodiment 3 is also changed on the basis of embodiment 1, mainly because the composition of the dispersant is different, and has: the dispersant is sodium lauryl sulfate, methyl amyl alcohol, cellulose derivatives, polyacrylamide , Gul Gum, Fatty Acid Polyethylene Glycol Esters Mixture.

Abstract

The invention discloses a waterproof nanometer aqueous coating. The coating comprises, by weight, 7 parts of nanometer magnesium dioxide, 5 parts of nanometer titanium dioxide, 6 parts of nanometer alumina, 6 parts of nanometer silica, 8 parts of nanometer ferrum dioxide, 8 parts of nanometer copper dioxide, 8 parts of nanometer tin dioxide, 8 parts of nanometer zinc dioxide, 8 parts of sodium dioxide, 8 parts of active carbon, 5 parts of a pure acrylic copolymer emulsion, 5 parts of rutile titanium dioxide, 3 parts of diatomite, 5 parts of aluminum silicate, 4 parts of gypsum powder, 1 part of a thickener, 1 part of a dispersant, 0.5 parts of ethanol modified polyurea, 0.2 parts of propylene glycol, 0.3 parts of glycerin, 2 parts of polyurethane and 2 parts of isopropanol. All nanometer materials especially added in the invention reduce agglomeration reactions and make the coating have an efficient lasting antibacterial property. The coating has the advantages of small degradation degree, stability, long service life, safety, environmental protection, adsorption of toxic gases, and sound insulation.

Description

technical field [0001] The invention relates to the technical field of a waterproof nano water-based coating, in particular to a nano-scale waterproof environment-friendly water-based material used for building surfaces. Background technique [0002] Most of the traditional waterproof and painting coatings will pollute and harm the production and construction environment and human affairs, and have a short service life. At present, waterproof and exterior wall coating materials have shortcomings such as short service life, aging resistance, and easy discoloration. . [0003] With the development of science and technology and the improvement of living standards, people are paying more and more attention to a healthy and safe lifestyle. In order to prevent the breeding of indoor bacteria, various antibacterial coatings came into being. Antibacterial agents used in coatings mainly include natural antibacterial agents, inorganic antibacterial agents and organic antibacterial a...
