preparation example Construction

[0046] A kind of preparation method of self-cleaning waterproof paint, it comprises steps:

[0047] S100 prepares modified acrylate emulsion by modifying acrylate with methacryloxypropyl vinyldimethoxysilane;

[0048] In S200, corresponding parts by mass of modified porous quartz powder, calcined kaolin, pyrophyllite, doped nano-titanium oxide powder, doped nano-zinc oxide powder, nano-zinc titanate powder, nano-bismuth titanate powder, graphite Disperse olefin in water, add dispersant, stir and disperse evenly;

[0049] S300 While stirring, slowly spray the uniformly dispersed mixed solution into the modified acrylate emulsion, and continue stirring for 30 minutes; and

[0050] S400 Add thickener, water repellent, plasticizer, defoamer, preservative and film-forming aid to the modified acrylate emulsion containing nano powder, stir at 600r / min for 1 hour, mix well, Prepared from clean water-repellent water-repellent coatings.

[0051] Wherein, the step S100 includes the st...

Embodiment 1

[0067] Siloxane-modified acrylate emulsion, doped nano titanium oxide powder and doped nano zinc oxide powder were respectively prepared according to the above preparation method.

[0068] 40 parts of modified porous quartz powder, 50 parts of calcined kaolin, 20 parts of pyrophyllite, 90 parts of doped nano-titanium oxide powder, 58 parts of doped nano-zinc oxide powder, 20 parts of nano-zinc titanate powder, 15 parts Parts of nano-bismuth titanate powder, 15 parts of graphene are dispersed in 120 parts of water, 4 parts of dispersant are added, stirred and dispersed evenly; under the condition of stirring, the uniformly dispersed mixed solution is slowly sprayed on 450 parts of silicon oxide In the alkane-modified acrylate emulsion, continue to stir for 30 minutes; add 25 parts of thickener, 5 parts of water repellent, 3 parts of plasticizer, 2.5 parts of defoamer, 1.5 parts of preservative into the emulsion containing nano powder , 3.5 parts of film-forming aids were stirre...

Abstract

The invention provides a self-cleaning water-resistant paint which is composed of a modified acrylate emulsion, water, a mineral filler, a nano photocatalyst and a chemical additive, wherein the mineral filler comprises cellular quartz powder, calcined kaolin and pyrauxite; the photocatalyst comprises doped nano titanium oxide powder, doped nano zinc oxide powder, nano zinc titanate powder, nano bismuth titanate powder and graphene; and the chemical additive comprises a thickener, a waterproofing agent, a dispersing agent, a plasticizer, a defoaming agent, a preservative and a film formation assistant. Thus, the paint has the advantages of high binding force, favorable water resistance and favorable self-cleaning capacity.

Description

technical field [0001] The invention relates to a building material, in particular to a self-cleaning modified acrylic waterproof paint and a preparation method thereof. Background technique [0002] Waterproof coating is a viscous slurry that is painted on the surface of a building and forms a thin film through the volatilization of the solvent or the chemical reaction between the components, making the surface of the building waterproof, anti-seepage and sealing. The waterproof film formed after the waterproof coating is cured has certain extensibility, crack resistance, impermeability and weather resistance, and can play a waterproof and anti-seepage effect. At present, there are two types of waterproof coatings on the market: one is polyurethane waterproof coatings, which mainly use polyurethane and asphalt as raw materials, and organic solvents such as toluene and xylene need to be added during use. Therefore, polyurethane waterproof coatings have many harmful volatile...
