Abstract

The invention provides a manufacture and construction method of a nanometer coating. Composite nanometer powder is weighed and inputted into deionized water, and then ultrasonic dispersed. Water-soluble polyvinyl alcohol solution and film former silica sol are added and ultrasonic dispersed to obtain the A component. Deionized defoamer, wetting agent, dispersant, antifreeze propanediol and pH regulator are added in a stirrer, and then rutile titanium dioxide, calcined kaolin, heavy calcium and talcum powder are added and sand milled, and then 4.0 percent of light ethyl cellulose solution is added and sand milled. The pigment and filler slurry is transferred to a paint blending tank and stirred, and then styrene-acrylic emulsion, alcohol ester-12, thickener SN612, defoamer CF-16 are added and stirred to obtain the B component which is coated on an asbestos cement plate and cured. The A component is sprayed on the surface of a template and cured. The invention has advantages of simple manufacture and construction, high utilization of nanometer material, low cost and good practicality.

Description

technical field [0001] The invention relates to a nano-coating manufacturing and construction method. Background technique [0002] At present, the general method of manufacturing nano-coatings can be divided into two categories: (1) nano-structured coatings. (2) Nano-composite functional coatings. There are surface dispersion and stability problems of nano-functional powders, especially the problem of nano-coating and sealing, resulting in poor efficacy, low utilization rate and unstable quality of nano-materials. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defect, a kind of nano-coating manufacture and construction method are provided. [0004] The technical solution of the present invention is: a nano-coating manufacturing and construction method, characterized in that: the nano-TiO 2 , ZnO, SiO 2 Proportionally added to the water medium, solid content 1.0-5.0%, nano-TiO 2 Accounting for 30-80% of solid cont...
